Default Camaro ZL1 1LE just ran a 7:16 at the Ring

Impressive!!


We will need to keep our eyes on them at track days in our 991 GT3's.

wow wee that is crazy time. is it possible all the amazing street car records have to do with the drivers skill? maybe drivers have just gotten much faster given all the attention these lap times now get.

The driver left NOTHING on the table. The video is a rush as the pro driver was just going ***** out the whole lap.

Amazing run. Can you imagine what that car would do if it were 500lbs lighter and had a DCT? lol

We may find out when the new ZR1 comes out with more power and probably 500lbs less than the ZL1 1LE. I doubt the dual clutch, but it will probably have a tweaked version of the great new 10 speed automatic. I'm predicting a 7:05 or less for that monster.

The driver was fearless. His skill level is off the charts. Of course much of this has to do with his familiarity of the course. I suspect he could have driven it blindfolded.

Apparently the driver's name is Bill Wise with BNR Racing. Definitely an epic lap.

Wait. How is this possible with a manual? I thought you lost 10 car lengths with every shift.

Exactly, and with the 650 ft-lbs of torque and wide ratios, I bet this car suffers even less than the 3 second deficit of the manual GT3, compared to a DCT.

I'm also struck by the pace of technical progress on display here, particularly with respect to tires.

Consider that in 2011 Lexus turned in a 7:14.6 with their LFA "Nurburgring" package. To do it they used a bespoke carbon chassis, double wishbones, a six speed sequential gearbox with eye-blink shift times and big, a lightweight V10 that reved to 9500 rpm.

Six years later Chevy is essentially matching that time by throwing a blower, beefed up manual transmission and go fast bits onto their $27k, steel bodied entry level coupe. The result weighs 577 lbs more than the LFA, costs 82% less and has on paper disadvantages in virtually every category. Frankly it should not work, and even five years ago it wouldn't: half way around that lap its tires would have melted under the weight of 3900 lbs and 650 hp.

You can see this car slithering around towards the end of the lap, the car getting more and more out of shape under power, but the tires never give up. That lets the engineers largely forget about weight and simply throw power at the problem, and that in turn is a game-changer. Forget rear wheel steering, 10 ms shift times and active aero. Not only are tires alone cutting nearly 2 seconds off the laptime per year, they are completely changing the engineering equation for the rest of the car...

Not to take anything from the chassis composure on display here. Very impressive.

The driver is more impressive than the car.

He was busier than a one legged man in an *** kicking contest. I thought I saw him send a text half way through. Epic run.

The "Ring time bragging rights" competition certainly creates a lot more questions than it answers. Cars (hello Huracan Performente) with minor to moderate changes suddenly dropping half a minute. Sports cars or "super" cars running faster times than "hyper" cars....It's tires, like Petevb mentioned.

I was at Viper Exchange a week and a half ago where they were putting together the 2 Vipers that are going for the production lap record this month on the Ring. To hear the stories that some manufacturers go to, to accomplish amazing lap times (OEMs, not privateers) is hilarious. The level of cheating just beggers belief. Pure racing slicks that have been cut by a tire maker to look like a street tire when mounted??? YUP.

Oh well, it's fun to watch. Just need to keep that massive grain of salt handy.

It's very unfortunate, in a way, that tire technology has progressed to this extent so quickly. It means that manufacturers have little incentive to make lightweight vehicles, which I believe benefits both driver enjoyment and the environment / conservation of resources.
