There’s A New Engine In The C8.R Corvette, And It Sounds Nothing Like Its Predecessor.

They say beauty is in the eye of the beholder, and although that’s true, it can also be in the ear of the listener.

Since the Corvette first hit the streets back in the 1950s, it was imbued with the beautiful and nearly magical sound of V-8 performance. It was a deep, bass-filled rumble that just oozed a feeling of power. Over the years, the sound emanating from Corvettes, both on the street and at the track, had a distinctive note that became synonymous with the car. When the Corvette moved to the LS1 in 1997, the firing order was tweaked a bit, and although the sound did change, it still had that deep rumble that we all love.

Chevrolet is super secretive of its new mill for the C8.R, so much so that it covered up the back hatch to keep out prying eyes. About all the team will say is that it’s a 5.5L DOHC V-8 fitted with a flat-plane crank. Power numbers are limited to 500 hp and around 475ish lb-ft of twist, but that’s all it will say. In fact this picture is about as close as you’re going to get to seeing the new C8.R engine.

But the only thing constant in the world is change. For the C8.R, Chevrolet Racing really changed things up with its new mid-engine marvel, but it wasn’t the engine placement that ended the car’s iconic sound signature. It was the engine itself. Gone is the deep baritone exhaust note, replaced instead with a high-pitched Ferrari-like sound. Think puberty in reverse. And although we love the sound of a wound-out Ferrari or other Italian supercars, having that pitch emanate from the back of a Corvette is something that will be hard to get used to. We’re not saying the sound is bad—it’s actually pretty badass—but it’s not even close to the sound signature we’ve come to associate with Corvettes.

The real culprit here isn’t the new 5.5L DOHC V-8 that Chevrolet moved to. Instead, it was the choice to go with a high-revving flat-plane crank. This drastically changed the firing order of the engine and eliminated the classic American V-8 sound that’s typical with the firing sequence of a traditional cross-plane crank. But we know what you’re thinking: “Well, this is just the race car, so I’m going to be able to get my V-8 rumble fix from the production car!” Well, yeah, for now. You see, for Chevrolet Racing to run this new DOHC flat-plane crank mill in the C8.R, it has to, according to the rules, run a similar engine in at least 300 production cars. So does this mean that an eventual C8 Z06 variant will lose its iconic exhaust note?

Chevrolet Racing tried hard to give race fans a great-sounding engine. And although the new 5.5L engine in the C8.R does have a unique sound, it’s nothing like we’ve grown accustomed to.

The C8 Corvette and Other NACTOY Finalists Discussed on Autoline TV

The 2020 Corvette Stingray was named as one of the three finalists for the prestigious North American Car of the Year Award and the winner will be named Monday morning (Jan 13th) in Detroit. The all-new mid-engine Corvette does have some stiff competition as it’s facing off against the redesigned Toyota Supra and the Hyundai Sonata midsize sedan.

If you’re looking for a scouting report on the three finalists, you’ve come to the right place!

In this recent episode of Autoline This Week, host John McElroy is joined by panelists Gary Vasilash, Jeff Gilbert and Lindsay Brooke to discuss the contenders up for what is by far the most important vehicle award of the year. All four members of the panel are “NACTOY Jurors” who tested each of the cars and they all weigh in on the strengths and weaknesses of each vehicle.

After watching this episode, I am feeling pretty good about the Corvette Stingray’s chances, but that Sonata does have a ton of style and technology for a $30K vehicle so it won’t be a given. Check out the full conversation below:

From Autoline Network via YouTube:

The North American Car, Truck and Utility of the Year (NACTOY) jury comprises roughly 50 automotive journalists from the U.S. and Canada. Every year they vote on the best new cars, trucks and utility vehicles that came out in North America. Three of the NACTOY jurors join us on Autoline This Week to discuss the three cars that made it to the finalists’ list, as well as some of the cars that did not make the list. They also predict which vehicles will win the awards for best car, truck and utility.

Panel: Garry Vasilash, Automotive Design & Production Jeff Gilbert, WWJ NewsRadio 950 Lindsay Brooke, SAE International John McElroy, Autoline.tv

Detroit Bureau Steve Burns will be live at the NACTOY award ceremony and will bring us any breaking news from the event. The North American Car, Truck, and Utility Vehicle of the Year awards will be announced on January 13, 2020, at 8 a.m. in Detroit.

Corvette Poised for Sebring WEC Return

#3 Corvette Racing Corvette C8.R, GTLM: Antonio Garcia, Jordan Taylor, Nicky Catsburg

Corvette Racing set for COTA-Sebring double FIA WEC run with C8.R

Corvette Racing looks set to contest the 1000 Miles of Sebring, in what would be the second consecutive FIA World Endurance Championship outing for the new Chevrolet Corvette C8.R.

Sportscar365 has learned that provisional plans are in place to run the Sebring WEC race alongside its two-car factory GT Le Mans class program in the Mobil 1 Twelve Hours of Sebring the following day.

It would come as one of the prerequisites from the ACO, which has stipulated that the Pratt & Miller-run team must run in at least two regular-season WEC races in order to be guaranteed a pair of GTE-Pro entries for the 24 Hours of Le Mans.

The team ran the Shanghai WEC race in 2018 in addition to Sebring last year with its previous-gen Corvette C7.R.

While declining to comment or confirm on any WEC plans beyond its COTA entry, Corvette Racing program manager Doug Fehan said that it’s been their intention to run two regular-season races in the 2019-20 WEC season.

“Right now, that’s the plan but we’re running down a road,” Fehan told Sportscar365.

“We haven’t refined what exactly that plan is going to be. I couldn’t give you every detail and widget.

“We’ve been busy for a couple of years trying to race and design, build and develop the new car. This adds to the challenge of all of that.

“I think most people would understand that we don’t have it completely defined yet.

“It’s a case of dealing it in an orderly fashion.

“We can’t become overwhelmed too much with what’s going on down the road when we have to focus on what we need to accomplish [in Daytona] in a couple of weeks.”

While set to give the new mid-engined GTE contender its competition debut in the Rolex 24 at Daytona later this month, the car’s second race will come just four weeks later at Circuit of The Americas, with a single entry having been submitted for the WEC replacement round.

Fehan said details on that program, including drivers, have yet to be determined.

He explained the reason for doing the additional WEC races is to “try as best we can” to support the globe-trotting championship.

“We understand the value that has to the sanctioning body and the value to the global fan base,” he said.

“We know it’s important but they also know the business side of it that prevents us from doing both things. They get that.

“I think they also appreciate how hard we’re trying to make all of the accommodations we can to keep the ball moving down the field. 

“It’s not easy for us and they know it’s not easy for us and they appreciate that.”

No Issues in 2019 ‘Super Sebring’ Endeavor

Fehan said the team faced no issues in its double-duty endeavor at Sebring last year, in what was only the second-ever time the team raced three cars between two different series on the same weekend. 

In addition to its over-the-wall crew and several other staff, drivers Antonio Garcia, Jan Magnussen and Mike Rockenfeller took part in both Friday’s eight-hour WEC race and the around-the-clock IMSA enduro the day later.

“That worked out great,” Fehan said. “We were lucky because we had enough equipment.

“It’s not like you can piggyback what you have set up. You’ve got to have a completely additional set of stuff.

“Between stuff that we had in stock and stuff that we had for the Cadillac program, we had enough in place.

“That system is getting better and we learned from that on all the things we did right and all the things that we know we could improve upon.”

‘Everyday Supercar’: A New Corvette Puts a Target on Ferrari’s Back

The $60,000 Stingray pushes its engine to the middle and expectations through the roof.

The new Corvette Stingray is racking up rapturous reviews and dominating industry awards.

From its dream-car debut in 1953 at the Motorama show at the Waldorf-Astoria hotel, the Chevrolet Corvette has kept its engine up front, where sports-car tradition says it belongs.

But with sales of many fast, fun cars on the wane — blame the rise of dully practical S.U.V.s, an aging boomer audience or a declining car culture — the Corvette’s creators saw the need for a radical about-face. The 2020 Corvette Stingray has moved its engine behind the driver and passenger, adopting the physics-approved layout that brought Ferdinand Porsche his first racing successes in the 1930s. Today, this approach is associated with money-torching supercars from Ferrari, Lamborghini and McLaren.

The long-awaited “mid-engine” Corvette easily outruns its formidable predecessor, as I learned during a time-warping desert drive near Tortilla Flat, Ariz. The eighth-generation “C8” Corvette is earning rapturous reviews and dominating industry awards, as a car that can take on European exotics that cost $200,000 and more, but at a $59,995 base price that reads like a misprint.

“It’s certainly a great moment in the car business,” said Eddie Alterman, chief brand officer for Hearst Autos and a former editor in chief of Car and Driver. “It’s nothing less than the democratization of the supercar.”

At General Motors, that democratization includes a virtual decree that Chevy’s relatively blue-collar baby generate vastly more sales than, say, its Porsche 911 nemesis, enough to earn its keep in profits. Yet sales of sports cars and muscle cars have plunged by nearly half since 2000, on track for just 230,000 this year, according to analysts at Motor Intelligence. A reborn Toyota Supra, despite huge fanfare, has found a lukewarm 500 buyers a month since its summer debut, fewer than one-quarter of the expected 25,000 to 30,000 first-year sales of the Corvette.

At Porsche, a single sport utility vehicle, the Macan, finds more buyers than all the brand’s sports cars and Panamera sedans combined. Unsurprisingly, the world’s speed merchants, including Lamborghini, Bentley and Jaguar, have developed S.U.V.s into their best-sellers around the world, with entries from Aston Martin and Ferrari on the way. Some of those companies had vowed to never sully their names with a sport utility. Never mind.

Into this minefield steps Tadge Juechter. As just the fourth chief engineer in the Corvette’s fabled 67-year history, Mr. Juechter holds one of the most scrutinized positions in the American industry, his every utterance parsed for clues to the ’Vette’s future.

The previous-generation Corvette, the first to wear the Stingray badge since 1968, also generated robust sales beginning in 2014. Yet Mr. Juechter and his team saw a car nearing its end, both in technical terms and its ability to win new buyers.

“We saw an aging demographic, the same faces at Corvette events year after year,” he said.

That honking, 6.2-liter V8 up front had become an Achilles’ heel. The Corvette’s top-shelf, $121,000 ZR1 edition was already pumping out 755 horsepower, keeping pace in an unprecedented industry horsepower war. Moving the engine aftward — shifting critical weight over driven rear wheels — became the only way to apply such monstrous force to the pavement while improving traction and stability.

The move risked alienating the Corvette’s tradition-loving buyer base. At a design clinic for owners of various sports cars, Mr. Juechter discovered that current customers were split roughly 50-50 on the mid-engine switch. But among supercar owners that Chevy hoped to conquer, 90 percent favored it.

“We had to go for it,” Mr. Juechter said. “We did it purely for physics rules, but the byproduct was that it would also appeal to a new generation. We try to respect the past, but not be stuck in the past.”

G.M. had teased the faithful for decades, experimenting with a midmounted layout in a series of fanciful prototypes, beginning with the CERV 1 (for Chevrolet Engineering Research Vehicle) in 1959. Finally, for the 2020 model year, the near-mythical mid-engine Corvette is here, including the coupe’s Ferrari-esque view of its V8, provocatively exposed below a glass cover.

The public’s first glimpse of the car, in April, supported the Corvette engineering team’s confidence. Mr. Juechter drove a prototype, its body work disguised by a black-and-white pattern, through a bustling Times Square, with Mary Barra, the G.M. chief, riding shotgun. Rolling, windows down, Mr. Juechter heard younger voices yelling, “Mid-engine Corvette!”

“We imprinted on young people a super passion for this car,” he said. “Our job is to push that, that every drive can be a joy, an adventure.”

Dodging Times Square tourists and Ubers in a 495-horsepower, roughly 190-m.p.h. sports car is one form of adventure. But in my Arizona test, including roller-coaster desert curves, this new model combined moonshot acceleration, handling, tech and versatility like no rival remotely near its price. That includes a 2.8-second catapult to 60 miles an hour, on a par with a $250,000 Ferrari 488 GTB; a sharply improved, jet-fighter-inspired cockpit; and a GPS-based video data system that records street or track drives, overlays them with animated telemetry readouts and lets drivers analyze their performance with racing software.

The Corvette is notably aerodynamic, and gets solid mileage.
New sports cars are safe and approachable for amateurs, yet still rewarding for skilled pilots.

“It doesn’t have the operatic Sturm und Drang of a Ferrari or Lamborghini, but it really is an everyday supercar,” Mr. Alterman said.

Fuel economy is surprisingly decent, roughly 26 to 28 miles per gallon at a steady highway cruise. The Corvette is notably aerodynamic, and can deactivate half its cylinders to save fuel. The latest driver-adjustable magnetic suspension, a G.M.-first technology now adopted by several European exotics, lets the ’Vette drive as smoothly as some luxury cars in its Touring mode, despite the sleeping-bear V8 just over your shoulder.

“It couldn’t be just a weekend toy,” Mr. Juechter said. “A lot of people use this as their only car.”

Perhaps because do-it-all S.U.V.s are strong-arming sales — and definitely because today’s fans won’t put up with punishing rides or dodgy reliability — the worldwide trend is all about more practical sports cars that are safe and approachable for amateurs, yet still rewarding for skilled pilots.

Many mid-engine exotics lack a trunk, because the engine hogs the space. Yet Corvette designers made room for a trunk that can fit two golf bags, in addition to the Porsche-style “frunk” up front where the engine used to go.

Even the carefree convertible model doesn’t neglect its chores, with an ingenious powered soft-top that tucks away without stealing an inch of luggage space. Welcome practicality does bring a visual downside: The wide, chunky rear deck makes the ’Vette a bit back heavy.

Proper fits aside, wishful fans didn’t find a little red-ribboned Corvette under their Christmas tree: A now-settled G.M. strike has delayed production until February. For Chevy’s pampered halo car, only about 12 units each hour will roll off the production line in Bowling Green, Ky., down the road from the National Corvette Museum.

In anticipation of huge demand, more than 400 workers have been hired to fill a second daily shift, including employees laid off from Chevy’s closed plant in Lordstown, Ohio. (G.M. plans to open a new battery plant there, part of a $2.3 billion joint venture with LG Chem of South Korea.)

Mr. Juechter is confident that Chevrolet can sell every Corvette it can build, for now. The real test comes after the initial frenzy subsides. Mr. Alterman points to an increasingly short, roughly 18-month shelf life for such high-profile performers, with fickle buyers and collectors always in pursuit of the hot new thing. He sees the Corvette borrowing from Porsche’s ultra-profitable playbook, keeping the lineup fresh with myriad styles, performance upgrades and personalization options.

Though Mr. Juechter wouldn’t comment on future models, the cottage industry of Corvette rumors cites development of a hybrid ’Vette with up to 900 horsepower.

The dominance of S.U.V.s and the momentous shift to electrics has automakers playing offense.

Aside from an industry explosion of superpowered sport utilities, Ford ignited a controversy when it unveiled a Tesla-baiting electric S.U.V. and called it the Mustang Mach E. The traditional Mustang is enjoying its own golden age of performance, including a bonkers Shelby GT500 with 760 horsepower and an affordable four-cylinder model that gets 32 m.p.g. on the highway. Yet Mustang sales continue to tumble.

And while traditionalists are crying foul over the Mustang Mach E — first S.U.V.s stole customers, now they’re stealing legendary names — Mr. Alterman suggests that this heresy won’t be the last. A five-seat, Corvette-branded S.U.V. could be the most “everyday supercar” of all.

“You’ve got that sub-brand of the Mustang that’s so evocative,” he said, “so why not draw on it? There’s an opportunity for Chevy to do the same thing.”

This Corvette achieved supercar-rivaling speed without a single drop of gasoline

Several companies are developing electric supercars but, for now, the fastest one of all is a modified Corvette.

Maryland-based Genovation Cars built an electric Corvette called the GXE, and that car just hit 211.8 mph at the Kennedy Space Center in Florida. That’s the same as a Ferrari SF90 Stradale. Genovation claims that is also a world record for a street legal electric supercar, but the company was competing against itself. The GXE set the previous record of 210.2 in September 2019.

The GXE boasts 800 horsepower, which is 45 hp more than the 2019 Corvette ZR1 — the most powerful production Corvette ever. The GXE is also based on the same C7-generation Corvette platform as the ZR1, rather than the mid-engined Corvette C8. However, the GXE is a hair shy of the ZR1’s 212-mph top speed — for now, at least. Genovation claims the electric car is capable of more than 220 mph. It will need that kind of speed to beat an upcoming crop of electric supercars.

Croatian firm Rimac claims its Concept Two will reach 258 mph, while the Japanese Aspark Owl boasts a claimed top speed of 248 mph. Running prototypes of both cars exist, but no customer cars have been built, and their manufacturers’ top-speed claims have not been independently verified. The second-generation Tesla Roadster has a claimed top speed of 250 mph, but the car hasn’t gone into production yet. The same goes for the Lotus Evija, which will surpass 200 mph, according to its maker.

The Bugatti Chiron remains the fastest car in the world, having achieved 304 mph in August 2019. A handful of other automakers are eyeing the 300-mph barrier, but with gasoline rather than electric power. While electric motors can produce absurd amounts of horsepower (of the cars listed above, the GXE is the least powerful), heavy battery packs put electric cars at a disadvantage when it comes to weight.

The GXE isn’t exactly a stripped-down track car, either. It comes with adaptive suspension, a 10-speaker JBL audio system, and 10.4-inch central touchscreen. Genovation plans to build a limited production run of 75 cars, with the first customer deliveries expected in 2020. The company previously quoted a price of $750,000, which could buy you 12 gasoline-powered 2020 Corvettes.

Ode to the Burnout

Save your letters. we know better.

Thanks to the curiosities of a liberal-arts education, I found myself with a 21-credit workload in my last semester of senior year, one that included a seminar on John Milton’s Paradise Lost. Published in 1667, the epic, 10-volume poem wraps itself around the biblical fall of man, painting a picture of humanity’s temptation from Satan’s view. Our professor argued that, deep down, Milton saw temptation as a kind of litmus test for the soul.

This story originally appeared in the December 2019 issue of Road & Track.

If that’s true, Performance Car of the Year might well be the bar exam for moral fortitude. Spend a week in the world’s most spectacular cars. Visit a beckoning track and some of the country’s best roads. Don’t go weak in the knees at the soprano trill of a 600-hp, twin-turbocharged 3.8-liter McLaren V-8. Try not to think too hard about being one of the first people on the planet to get your hands around the neck of the mid-engine Corvette. Be a good boy. But as John Henry opined, a man ain’t nothing but a man. We were somewhere outside Tahoe when that wide lake of asphalt and six days of sleep deprivation finally got to me. I’d spent the better part of a week pretending to be a professional. But when I found myself alone, in the first mid-engine Corvette, with acres of empty ski-park pavement ahead, no amount of restraint or discipline could stand up to desire. I had found my garden, and the serpent was waiting.

I’m more of a middle-path kind of guy, anyhow.

Burnouts and donuts, juvenile as they may be, are as pure a celebration of the automobile as you’ll find. Sports cars are wrapped up in the quandaries of personal freedom more than any other vehicle on four wheels, in pushing the bounds of legally and socially acceptable behavior. We do the math every time we choose to take the convertible to work instead of the family crossover, when we push a brake zone a little deeper, when we lean on the accelerator while chasing shadows up a mountain. Or when we turn the rear tires to billowing clouds. Modern life is increasingly a series of confined boxes, and a sports car fits in none of them.

A good burnout isn’t entirely frivolous. If you listen, it will tell you a thing or two about the people who put the car together. In this age of eager litigation, some automakers simply deny you your inalienable right to light tires on fire. Doesn’t matter how many systems you shut off, a digital overlord will step in and pull power until you get back to acting like an adult. On a certain level, it makes sense. If you sat down and designed a sports car by bullet point, listing necessary functions on a spreadsheet, a burnout would be last on the list. Apart from drag racing, the act serves no logical function. But it’s such a fundamental question: Who’s in control of this vehicle? You or some attorney in Michigan?

This next-generation Corvette has moved the badge further from its roots than any Vette before. And from the moment I saw it sulking in the California sun, I needed to know if the thing remembered how to be America’s sweetheart. So I switched off everything and leaned into mechanical masochism. Somewhere, Satan smiled. The car performed a perfect pirouette, that pushrod small-block screaming at the sky while the tires went to vapor. A devotional to free will. Automotive enthusiasm’s shit-eating grin.

If God really wanted us to be good all the time, he wouldn’t have planted that apple tree. Or given us rear-wheel drive.

2020 Corvette Stingray Convertible in Shadow Gray on Display at GM’s Detroit Headquarters

Photo Credit: Kevlar Bike- Corvette Forum

Inside General Motors’ headquarters known as the Renaissance Center in downtown Detroit is a large turntable that is currently featuring all eight generations of the Chevrolet Corvette. The new eighth-generation iteration of America’s Favorite Sports Car is a 2020 Corvette Stingray Convertible painted in Shadow Gray Metallic.

A Youtuber named portcarlingboats captured a minute of video as the new C8 Convertible spins by him on the turntable.

The visible cues on this Corvette show that it’s a non-Z51 model but it’s loaded with some great looking options that include the two-tone Natural and Black seats, Spectra Gray Trident Wheels and red brake calipers. We also prefer the bright Corvette emblems to the the darker versions on this exterior.

Corvette C8 convertible on display at the GM Headquarters in Detroit Michigan on Sat Nov 23 2019; part of 8 generations of corvette convertibles on a rotating display from 1953 to today; C8 supercar, exotic car, european sports car; this is the car that will change the automotive for years to come; can’t wait for the all electric version to come- No sound

On his original post on the Corvette Forum, Kevlar Bike tells us he is Canadian and that the C8 Corvette on display inside the GM’s HQ is the closest C8 Corvette on display so he made the trip to check it out.

Shadow Gray is one of those colors that change drasticly when viewed in the direct sunlight and the lightings inside the RenCen does nothing to show-off the varying hues within. As a comparision, here is a quick walkaround of a Shadow Gray Metallic C8 at the NCM earlier this year from CorvetteBlogger contributor Jeremy Welborn:

Most Expensive 2020 Chevy Corvette Convertible Costs $113,955

Configurator with pricing info is up, so we’ve decided to max it out.

We’ve been periodically checking Chevy’s website for the Corvette C8 Convertible configurator ever since it went up at the beginning of October to see if there’s pricing available. You can finally know how much the desired spec is going to set you back as the configurator now has all the pricing details included. Much like we did with the coupe a few weeks ago, we’ve decided to max out the online builder in an attempt to find out how much a fully loaded Stingray Convertible costs.

We’re not going to go through each and every option as we did in the previous post because most of them are identical. It’s worth pointing out the convertible commands a $7,500 premium over the coupe and it starts at $67,495 for the entry-level 1LT. Go for the better-equipped 3LT and the price jumps to $78,945, and then you can add this $995 Long Beach Red Metallic Tintcoat paint and a dual racing stripe also priced at $995.

The most expensive options available for the C8 Convertible are the $5,000 Z51 Performance Package and the $4,850 Grounds Effect Kit, but on top of these, you can also add the $2,095 grille insert and $1,145 side mirror caps both finished in visible carbon fiber. Another pricey option is the $2,695 wheel set measuring 19 inches up front and 20 inches at the rear, with a five-spoke design and a Performance Pewter-painted finish.

If you truly want to go all out with the configurator, Chevy will be more than happy to provide you with a two-piece leather travel bag set for $1,450 as well as indoor and outdoor car covers each priced at $460. Inside, a carbon fiber trim adds $1,500 to the final bill, while the Competition Sport bucket seats are an additional $500.

With all the boxes ticked, you’re going to end up with a 2020 Corvette Stingray Convertible that costs $113,955, plus an additional $110 worth of dealer-installed

As you’re probably aware by now, production of the C8 has been delayed until February 2020, so it’s going to be a long wait to park the new Corvette in your garage.

VKTRY Performance Insoles Embrace Carbon Fiber For Energy Return

If just a touch of carbon fiber can provide benefits for athletes, then VKTRY founder Matt Arciuolo figured engineering a full-length carbon fiber insole had a range of untapped potential. Following nearly a decade of research and development, all sparked by an effort to provide the USA Olympic bobsled team more explosiveness on their starts, Arciuolo patented a carbon fiber footwear insole customizable to provide performance benefits for athletes far beyond the bobsled. 

VKTRY, now four years beyond that patent and three years since producing its first commercial insoles, has made inroads in major college and professional sports the country over, gaining backing from LSU’s director of athletic training Jack Marucci, now-retired Lakers trainer Gary Vitti, Red Sox doctor James Creps and a handful of professional athlete endorders. 

“Insole inserts are passive devices designed to absorb shock, but they don’t generate energy or return energy to the athlete,” Arciuolo says. “Instead of a passive device, I designed this carbon fiber insole to store energy and return it.” 

The process works in four steps, all using the impressive strength-to-weight ratio of carbon fiber. When the heel hits the ground, the VKTRY insole absorbs the shock of the heel strike and returns it like a trampoline, Arciuolo says. When the second phase of an athlete’s gate moves their full body weight over the middle of the insert, the arched design deflects and adds cushioning. “The third phase is where the magic happens,” he says. When athletes pick their heel up to take a step or jump, the carbon fiber stores the energy at the ball of the foot, returning it in the toe-off phase — phase four — “where all the energy stored in the first three phases is returned.” The insole isn’t generating energy on its own, instead using an athlete’s energy and returning it to them for efficiency and explosion.

Using independent studies, including one from Southern Connecticut State University, VKTRY CEO Steve Wasik says science backs that claims, showing the company’s insoles provide over a 9 percent rate of force development, basically explosiveness, than not using the product. 

The carbon fiber is engineered with multiple layers of fibers in different lengths, makeups and directions to offer flexibility where needed and stability in other areas. 

VKTRY was designed for use across multiple sports — major footwear brands from Nike to Asics have started employing carbon fiber in long-distance running shoes for linear benefits — and Wasik says they’ve seen adoption from football to baseball, but have found basketball and volleyball players especially enjoy the energy return for higher jumping ability and less force upon landing. “We hear some great stories from athletes who have suffered from sore knees or shin splints and the pain is gone,” he says. 

The original bobsled design requiring the insole to fit in the tight confines of a spike helped create a product ideal for all athletes, Arciuolo says. “The challenge was not only getting something that worked in terms of propulsion, but also that fit in the shoe,” he says. The carbon fiber portion of the product weighs less than an ounce and is less than a millimeter thick. A proprietary polyurethane top cover provides additional comfort. 

VKTRY isn’t a one-size fits all proposition, with Arciuolo calling it a “truly customized product.” It comes in five different “pro levels,” which are basically different flex levels. Lighter athletes with smaller feet require more flex than a 320-pound football player. To get the same propulsion performance, insoles require customization based on sport, weight and foot size, so an algorithm helps find the best flex level for each athlete. The insole is further customized by sport, using different thickness and sizes. 

“The VK is the best combination of injury protection and performance I have ever seen in insoles,” Vitti says. 

Endorsers of the brand also include Vladimir Guerrero Jr. of the Toronto Blue Jays, Anthony Miller of the Chicago Bears, Josh Norman of the Washington Redskins, Lexie Brown of the Minnesota Lynx, Myles Jones of Chaos Lacrosse Club, George Springer of the Houston Astros, CrossFit world champion Annie Thorisdottir and plenty more. 

Creps says that “for the first time, athletes can experience stabilization, shock absorption and propulsion in a device that is specifically tailored to their size and weight. This is a game changer.”
