Thanks for the correction, I never saw the episode, and was relying on 3rd hand witnesses who were there.Bonneville was limited to 1 mile. James got the cts-v to 163mph. the Z06 got to 176mph.
Getting to 200mph is tough. I got my 996 turbo to read 198 in NM. I was probably going a little over 190. You need a long straight! I got to 196 when a little dip in the road got me 198. Then a hill came up and I broke like hell. Also, the circumstances have to be right. Wind and tire pressure play a big roll. And the porsche gets up to 170 pretty easily, but after that it's pushing. The video of the beefed up cts-v automatic in dubay shows it gets to 195mph. It's also pushing it in the last 20mph. I'd say the M5 is a bit lighter and less wind resistance. I read it could do 205mph.
I tried to call today, but wasn't sure I got through. Call me at 951 270 0808, I'll be here another 30 minutes, or I'll try to call again tomorrow. I don't carry a cellphone, or I'd have you call that.There have been SEVERAL customers that have gone over 200mph. Including a few in Dubai. Any vids showing over 321 KMH shows them hitting over 200..
I know for a fact that my car has seen it 2 times...
As for autos, YES stock form they are limited to 175. That dont mean they wont go faster with the limiter removed. They keep pulling VERY quickly all the way up...
m3's and m5's are limit to 155 mph only in the usa...The M3 only has 400 HP and it can do 203. If anyone with a V2 lives or visits Sweden, you can go to the SuperCar Shootout thing they have over there. I have heard that a government mandate requires speedos to read 5-7 MPH more than actual.
You read somehwere that the V needs a larger rear spoiler to reach a higher top end speed? Where? Do you realize a larger spoiler will increase downforce and most likely Cd? Also, as you add downforce the car lowers itself as speed is increased. A spoiler adds aero grip in addition to mechincal grip, but hurts top end.I read somewhere that the aero whold have to be tweaked ie... larger rear soiler, lower the front end...etc... Right now it's rev limited to 160. I had mine at or just above 150 mph... still had pedel to go...
Make sure you're close to a dealership so it won't be a long tow there.That dont mean they wont go faster with the limiter removed.
The CTSV M6 traveled an average of 191.2mph for an entire lap on GM's Desert Proving Grounds 5 mile circle track. Even with banking, it was pulling 0.3 G lateral continuous. On level straight ground, it would likely pick up ~3 mph.When I was clocked at 174.586mph at Bonneville, the GPS said 181, and the reported axle speed (engine RPM) was 188mph. The GM speedo reading freaked out, as it went back to 0 and started counting again when it hit 256kph (155'ish?).
