2009 Chevrolet Corvette ZR1 Thread

^^ I hear GM is giving Al Gore one for Christmas

Like Lincoln at Gettysburg, General Motors chairman Rick Wagoner uttered but a few select words to inspire a whole new Chevrolet Corvette. Reacting to plans for the $65,800 Z06 outlined by chief engineer Tadge Juechter no score and three years ago, Wagoner mused, "I wonder what this team could do for $100,000?"

The answer is the 2009 Corvette ZR1, engineered to be the most powerful, best performing, highest priced Chevy in history.

The perfect car for Optimus prime

It's really, really AWESOME! Damn, never thought I'd like a Corvette this much.

The tires are Michelin Pilot Sport Run flats- I saw a set of prototypes in the factory that makes the wheels for the ZR-1, when I was getting my Z06 track wheels.
I have put out feelers to try and get a ZR-1, but I heard they are making 2000 a year for the remainder of the C6 lifespan, so they shouldn't be too hard to get after the initial excitement dies down. I had one of the first 1990 ZR-1 back in the day.
It will be interesting to see how the ZR-1 does on the track- I think the Z06 will remain the preferred track car. 300 pounds is a lot. I don't think softening the rear has anything to do with performance in this case- its to make the ZR-1 more agreeable to the touring crowd. My Z06 has no problem even on a bumpy track like Sebring.

And since launching a car with so much horsepower can become a violent, axle-hopping mess, Chevrolet has come up with two novel countermeasures.

First are the rear shocks. When you're stopped and the clutch pedal is depressed and you pile on some revs, the car assumes you want to launch it hard. It automatically softens the compression damping of the rear shocks, and this allows the rear end to squat and effectively shift more weight to the rear of the car for added traction. At the same time, the rebound damping of the rear shocks goes up to 99 percent of full stiffness. This means that the rear cannot spring back up under power in the up-and-down monkey motion of axle hop.

All this is perhaps the cleverest use of adjustable shocks that we've ever heard of. Also, according to Juechter, the standard magnetic shocks allow the ZR1 chassis team to use softer springs than the Z06 for a more compliant ride. To further mitigate power hop, Chevy has also fitted the ZR1 with axle half-shafts of different diameters (33mm on the right and 40mm on the left).

We'll see how all of this works next year when we finally get to drive the thing. We might just try a hard launch or, you know, several.

F1 active ride cars did that. These semi-active suspensions truly impress me, along with the rest of the car.
