In the past year, Nürburgring has been all the craze among auto manufacturers. Nissan, Porsche, and now Chevrolet and Dodge have been doing whatever they can to create the fastest super car and they go to Germany to find out. Chevrolet turned their venerable Corvette into the ZR1 while Dodge created the American Club Racer (ACR) version of its Viper.

Some might not even be able to notice the differences on the Corvette ZR1 design compared to other Corvettes. Much of the design carries over from the Z06 version. There's an extensive use of carbon fiber but you can't tell. There's also wider fenders, a new hood, revised air dam and other various bits and pieces but the design is kept unsuspecting.

The Viper holds nothing back in trying to gain every ounce of performance in its design. A revised hood, front air dam, and gigantic wing are all there to provide 1,000 pounds of downforce at 150 mph. That's 10 times more than the regular Viper. Unlike the ZR1, the ACR wants to show that it means business with a two tone paint job and racing stripe to top it off.
The ZR1 and ACR's hoods are polar opposites. The ZR1's hood is more tasteful than the ACR which really goes to the extreme. The Corvette features a window so that the top of the engine can be seen even with the hood closed. The ACR doesn't bother with aesthetics and adds louvers and a new design all for the sake of performance.
The Viper which even in stock form looks menacing is even more vicious in ACR form. The ZR1 shares the Z06's aluminum chassis but replaces panels with carbon fiber.
The ZR1's carbon fiber front lip spoiler is kept moderate unlike the ACR. New fenders add unique side vents to the ZR1 and are also made of carbon fiber. The ACR takes styling cues from race cars which makes sense because its more of a race car kept street legal.
The ZR1's rear fascia is left relatively unchanged from the Z06 version. The Corvette is devoid of any large wings but has a small trunk spoiler to help aerodynamics. The Viper's wing would feel right at home on any other race car. The quad exhaust pipes exit the ZR1's rear versus the ACR's side exhaust which leaves room for a rear air diffuser.

NOTES
The ZR1 initially ran a lap time at Nürburgring in 7:26.4. Since then, It was able to run a 7:22.4 time which is a mere .3 seconds more than the ACR's time. So close yet so far away.

The current generation Viper is expected to end production in 2010 but don't fret, a new one is coming in 2012.
