Chevrolet Camaro ZL1 takes aim at fastest Ford Mustang

Chevrolet just unveiled the most powerful Camaro and the fastest Corvette it's ever built in demonstrations at its Michigan proving track. Fast? You betcha.
The 580-horsepower supercharged Camaro ZL1 aims "right between the eyes" at Ford's 550-horsepower Mustang Shelby GT 500, chief engineer Al Oppenheiser said. You'll be able to get one in the first quarter of 2012.
Meanwhile, the 2012 Corvette used "barely street-legal" new Michelin performance tires to cut a stunning 7.seconds off the car's lap time at Germany's legendary Nurburgring racetrack, Corvette chief engineer Tadge Juechter said.
Neither car will sell in large numbers, but they should generate lots of profit from buyers who want the newest, fastest and best. And the hyper-fast sports cars polish Chevy's performance credentials at the same time the brand is boosting its reputation for fuel economy with cars like the upcoming subcompact Sonic, the Volt electric, and the 42-mpg Cruze Eco compact.
The high-performance Camaro ZL1 is about more than the brute power of its 6.2-liter V-8. It comes track-ready with features like a six-speed tap-shift automatic transmission, head-up display, magnetic ride control, standard oil, transmission and differential coolers and track-tuned stability control led Chevrolet to draw comparisons to exotic cars like the $196,800 Audi R8 GT V10.
And Chevy touted that its Camaro on steroids has more horsepower than a Ferrari 458, more torque (556 lbs.-ft.) than an Aston Martin DB9 V12 and a better power-to-weight ratio than a Porsche 911 Carrera GTS.
Take that, Mustang lovers.
The Corvette's Michelin Pilot Sport Cup run-flat tires have a unique tread pattern, with the outer third of the tire surface very nearly slick, like the fastest racing tires. The tires cut a Corvette ZR1's Nurburgring lap time to 7 minutes and 19 seconds.

2012 VW Passat, Audi A6 earn IIHS "Top Safety Pick"

Two redesigned sedans from the Volkswagen group -- the 2012 VW Passat mainstream, mid-size sedan and the 2012 Audi A6 large luxury car -- have earned the coveted "Top Safety Pick" ratings in testing by the Insurance Institute for Highway Safety, the insurance industry's research group.
To get the rating, they had to get the top score of "good" in IIHS front, side, rear and rollover crash tests, some of which are more stringent than the government crash tests.
TEST DRIVE here: The 2012 Passat is an interesting, satisfying new alternative in the Accord-Camry universe.
Neither car has been tested by the government, yet, so they haven''t gotten their ratings on the feds' star system.

To get a "good" in the stricter IIHS rollover test, vehicles must withstand force of at least 4 times their weight without failing (the feds require just a 1.5 ratio). The Passat scored an impressive 6.3 times its weight. The heftier A6 scored 4.9 times its weight.
The old Passat was also was a top pick, though the new one proved to be even sturdier on the roof test. The A-6 moved up -- the old model missed top pick status because it fell short, with a 3.8 force-to-weight ratio on the roof test.
The IIHS has, in the past, also required stability control to get the top rating, but as of Sept. 1, government safety rules require all new cars to have ESC.
