EXCLUSIVE 992 GT3 RS vs Corvette Z06 vs BMW M4 CSL w/ Randy Pobst — Cammisa’s Ultimate Lap Battle

We're going on a race track, these are three of the fastest production cars ever made, they've got our compound tires, they've got arrows and if it weren't currently three degrees colder than the surface of Pluto, we could see lap times around Willow Springs faster than us. I have never seen before one of them is Front Engineers one is mid-engined one is rear-engined they all send their power to the rear wheels from a four liter, five and a half liter and a three liter with two turbos combined they have more carbon than a crematorium, speaking of carbon, we have a real record maker here with us today his name is his name his name his name is Randy post and we have three of them they are scca hall of fame racing drivers they won the Rolex 24 Hours of Daytona twice twice and today they go abroad what are you doing?

I'm trying to say mostly good things about using social media. Oh, and what's up with this smoke. It's a heroic photo. Bomber car racing drivers have to eat. I love them. guys, oh, in a vacuum, any Porsche is awesome because it would be awesome to put any Porsche inside a vacuum. Porsches aren't typically found in a vacuum, they're found on race tracks, and on race tracks, race cars run on more than just the clock. Let's compete with each other, our race begins with the new 992 Porsche 911 GT3 RS. It has a 9,000 RPM, 4-liter, 518 horsepower engine that punches well above its weight.

This is because the 911 punches below its weight. It's by far the lightest car here, that light advantage. It wasn't enough a while ago, when we were racing the regular GT3 versus the surprisingly fast Corvette Z06, which was faster in a straight line, the GT3 RS has an Arrow that will slow this car down even more on the straights, but on the curves the arrow will help, will it be enough to keep up with the Z06? Is Randy prepared to use DRS and what color underwear is Randy Nomex wearing? It is not a color. We've established how fast the Z06 is in a straight line, but this isn't what that means.

Corvette is about if you want to win a drag race in a Corvette get an e-rig we did it it was awesome you should check it out we'll link to it below the Z06 is the track special Corvette and this car package on z07 amplifies it. Even further, this is 3.6 inches wider than the base Corvette, all to fit huge Michelin Pilot Sport cup 2rs tires, just like the Porsche. The z06's flat V8 revs to 8600 RPM and makes the most power of any naturally aspirated production V8 ever and 152. more horsepower than a Porsche, that means the Chevy will be faster than the GT3.

What about the BMW? The CSL nickname is back and don't underestimate it. Firstly, Willow Springs is at elevation and has two turbochargers that will ensure it runs. their maximum power all the time, which is decidedly not going to be the case with the other cars and look, we all know BMWs that make more power than you'd expect anyway. Secondly, the M4 CSL has the least extreme aerodynamics, so it will suffer even. less in a straight line and despite being based on a big fat luxury sedan it somehow still weighs less than the Z06 Jason this is a crumbling street tire how am I supposed to do a quick lap on that well?

Step one, stop complaining, take a completely good look. BMW tried but in the end couldn't get the optional tire on this car, the same Michelin Pilots sport cup 2, these are tires that are on the other cars, they are barely legal track tires, these are street tires, they are Pilot Sport 4S , but it's absolutely cold here, right? Now, those tires might have a cup performance advantage over ours. In other words, don't screw it up. Randy, foreigner. I told you. Randy is fast. Now let's rewind the tape, go back and find out what happened and what that frontstretch was like.

It's just a big long run uphill and into a headwind, so the BMW really had its work cut out for it because it came out of the last corner going 11 miles per hour slower than the pressure, but it not only made up for those 11 miles per hour. hour but also added another 5.3 reached 153 miles per hour which is a different league of speed foreign turbos at his job Randy was able to brake in the Porsche 50 feet after braking in the BMW and when he did The craziest thing is that, despite For all their differences, all three cars arrive here within a foot of each other, think of Willow's turn two as a big, long skid pad that rises six stories in elevation in more than 180 degrees of turn, and what does is measure tire grip plus a car's ability to put a ton of power to the ground at high speed, well this is where the Porsche 911's rear engine weight distribution really starts to pay dividends.

Griff increases one to two hundred miles per hour. He has never seen anything so high, the cars enter very close together but the Porsche immediately starts walking at its average speed in the curve. It's 7.6 miles per hour faster than the BMWs the grip just isn't there this is a handful that's not really where the competition is here it's still 3.6 miles per hour faster than the Corvettes it feels good but it's not putting up the numbers it It is a There is a big difference in grip and this results in the Porsche having a three car lead over the Corvette at the end of this corner and 10 car lengths over the foreign BMW.

The turn three complex really separates a good chassis set-up from a great chassis set-up; in other words, she is a complete mother and this is the reason why you appear on camera with a full stop and just when you turn on the road, the road becomes very uphill, well that is good uphill and before the Camera means you have plenty of grip, however, just when you think you have it all. I discovered it right on the Apex, when you're about to get power back on, the tilt arm goes away, which is really easy to control there while you're going uphill, but you have to do it because you have to get the car back to the side left in preparation for the second half of the S, which is a right turn that goes up and over the top of the hill.

A big push to break the hill is unusual there, however, it was right here in the braking zone where Randy first realized something. wasn't quite right with the Z06 oh boy stop stop stop stop oh no stop our data clearly shows that in the turn three braking zone the Z06 couldn't even match the braking performance of the BMW even though the Vets tires were much more aggressive than before. Randy slowed the Z06 and turned, he had to drive the rear, although not as much as he had to do in the BMW, this is a pretty wild man.

I'm going to struggle with this car, the complex downhill turns four and five are all about combining braking and cornering, something the BMW didn't do well, the Z06 was much easier to drive, especially on the road of the pitch, good grip at the start, reduces power, while the Porsche was rock solid and simply extended its lead, breaking there. I don't want a gearbox. Next up is turn six, which isn't a big corner, but turns into a jump if you're in a fast car. The W is a really fast car. It's on the left, that's right. Oh, definitely rebellious.

Bump six is ​​a really important turn because its exit speed prepares you for the entire back section of the track. Here the Porsche was perfect. This car doesn't roll, it doesn't pitch. The shocks are surprisingly good at controlling the body, so I'm full speed on the jump at six 120 at the start. I had never seen anything like it. Randy had to be a little more cautious in the Corvette. I don't know if I can stay here. It's a small movement. a little oversteered in the middle of the six in the tail um the Porsche is the slowest accelerating car of the three, enters the back straight at the highest speed with BMW proceeds to lift its skirts, spool up the turbos and explode towards the other two, it is still the Porsche. that gets to turn eight first I'm thinking about the wing on the arrow we're carrying a lot of speed over 140 on the road in stuck just stuck Randy enters this turn at 143 miles per hour in the Porsche 144 miles per hour in the Corvette and 145 miles per hour in the BMW think about it look at that corner turn the wheel at 145 miles per hour crazy especially in a car without Aero like the CSL there is no way just don't trust it in case this seems anything less than completely crazy let's say it So these two cars in Cup Two have tires that average 130 miles per hour around the corner during that time, the whole time they are pulling between 1.2 and 1.3 G of lateral acceleration that lasts longer. . of 17 seconds and they cover over half a mile doing that, if you experienced that speed, that level of Cornering Force for that long anywhere else on planet Earth, you would end up in a coffin and if Randy tried to maintain that speed in the BMW , he would have ended up on the ground too, sweating here trying to keep up with me, but now I know what all those other guys at the races were going through all the time, modesty for the win, Randy's minimum speed here in the BMW .

At one hundred miles per hour, the Porsche and the Z06 never went below 127. That's the difference Arrow makes, by the way, at this speed the Porsche generates a thousand pounds of downforce, and yet, to everyone's surprise, the Z06 and 911 are tied. Going through this curve in hundredths of a second, although the Corvette is 130 feet behind the Porsche, meanwhile the BMW is two football fields behind, halfway between the turn point and the exit on nine, we are going to exit to the front straight, I see. If I can take advantage of the torque, I'll need that torque because on the tight Kink entering the frontstretch, the BMW drops up to 90 miles per hour compared to the 98 Corvettes and the Porsche 101.

Oh, not as stable. I'm going to be a little careful here, fire up the little Harvester moment at the Yahoo exit, once out of Nine the drag race begins again to see how much ground the BMW and Corvette can take up, sweet and it's powerful too, it's barely making it, but it's winning the portion where the Porsche wins, the slowest car wins on the track, it may be the slowest in a straight line, but the 911's combination of grip, aerodynamic power braking and composure put it just ahead of the much more powerful Z06, which landed just nine cars behind or just six-tenths of a second and the BMW, well, is 788 feet behind.

BMW might have been in a different zip code, but it's the fastest BMW we've tested at Willow Springs, beating even the big M5 CS. by six tenths of a second, all without its sticky optional tires; In other words, this M4 certainly did its CSL badge proud and the Z06, despite the frigid temperatures, tied with the 759-horsepower Lamborghini Aventador SVJ, whose ideal conditions almost matched a Porsche that costs almost exactly twice as much and Porsche, the 911 GT3 RS is effectively a road-legal race car; Not only did it set an incredibly fast lap time but it was easy to drive from start to winning finish, so there you have it three very different formulas for the track. toys that share the same objective but surprise if you want to set the fastest lap around Willow Springs in one of these monsters you will have to choose the slowest foreign car
