ROLEX 24 AT DAYTONA – AN IMPRESSIVE DEBUT FOR THE NEW CORVETTE C8.R

The 58th Rolex 24 at Daytona, the first round of the 2020 IMSA WeatherTech SportsCar Championship season, saw the first race for the new Corvette C8.R, the participation of an all-female driver line-up, 2019 NASCAR champion Kyle Busch’s first start in a 24-hour race and Ben Keating at the wheel of two different cars.

A NOTEWORTHY DEBUT FOR THE NEW CORVETTE C8.R

The #3 Corvette C8.R finished the first 24-hour race of its career in fourth place in GTLM (the equivalent of LMGTE Pro at the 24 Hours of Le Mans). Drivers Antonio García, Jordan Taylor and Nicky Catsburg encountered zero problems with the car and completed 785 laps (nearly 5,000 kilometers). Unfortunately, the same cannot be said of the #4 Corvette C8.R of Gavin-Milner-Fässler. As the car was in the top 5 in its class going into the ninth hour, an oil leak caused the car to return to its garage. The leak was found to be in an area that forced the mechanics to remove the engine for repair and the work took almost nine hours. The #4 was then able to hit the track again and finished the race in 36th place.

Much like the 24 Hours of Le Mans, the 24 Hours of Daytona is an extremely challenging race. To make it to the checkered flag with an all-new car is already a major accomplishment for Corvette Racing. The American team’s next stop is the 6 Hours of the Circuit of The Americas on Sunday 23 February in Austin, the fifth round of the 2019-2020 FIA World Endurance Championship season.

AN ALL-FEMALE DRIVER LINE-UP

All-female driver line-up Christina Nielsen, Katherine Legge, Tati Calderon and Rahel Frey shared GEAR Racing powered by GRT Grasser’s Lamborghini Huracan GT3 in the GTD class, but the car was forced to retire after a fire.

KYLE BUSCH ENJOYS HIS FIRST ENDURANCE RACE

2019 NASCAR champion Kyle Busch took the start in his first Rolex 24 at Daytona at the wheel of the AIM VASSER SULLIVAN team’s Lexus RC-F GT3. Along with teammates Parker Chase, Jack Hawksworth and Michael de Quesada, Busch finished 26th overall and ninth in the GTD class. The American driver pulled off a double and a triple stint without the slightest mistake and said after the race he really enjoyed the experience and hopes to return for the overall win.

BEN KEATING DOUBLES DOWN

Ben Keating participated in his 10th Rolex 24 at Daytona at the wheel of not one but two cars: the #52 ORECA 07 fielded by PR1 Mathiasen Motorsports in the LMP2 class and the #74 Mercedes AMG-GT3 fielded by Riley Motorsports in GTD. Both cars crossed the finish line, the #52 ORECA 07 in 10th place overall and second in its class two laps from the winners, and the #74 Mercedes AMG-GT3 in 29th place overall and 11th in its class. This was the fifth time Keating participated in the race with two different cars.

Exclusive! C8.R Corvette 5.5L DOHC V-8 Pics and How the Flat-Plane Crank Alters Its Iconic Sound

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.

Excerpt from USA Today….

“The Corvette has existed in a category all its own as an American car,” said Hagerty CEO McKeel Hagerty. “It’s a pretty magical story through and through. It’s very evident they’re about to do it again

“The ‘Vette, a Chevrolet model assembled in Bowling Green, Kentucky, is getting one of its biggest changes yet: The engine is shifting from underneath the hood to the middle of the car, making it a “mid-engine” car much like some of Europe’s speediest vehicles. That change is aimed at making the vehicle even faster and better able to navigate sharp turns.

How powerful is the 2020 Corvette?: Rumor is it was warping the frame in tests

But expect eye-popping numbers for the loaded editions, including a possible ZR1 supercar.

Rumors were flying earlier this year that GM had to delay the new Corvette because it was so powerful that its frame was warping in track tests. Industry observers have speculated that the high-flying version could achieve an astounding 1,000 horsepower.

The extra-powerful edition is sounding like an “unbelievable performer and fire-breathing monster,” Hagerty said.
