Car and Driver: Audi RS5 vs. BMW M3 vs. Cadillac CTS-V

Car and Driver ventured out to the German Autobahn and the 'Ring to test the three hottest sport coupes out today. The Car and Driver test team burned up 2,000 dollars of fuel testing the coupe's 178 mph top speed. Car and Driver loved the RS5's gearbox, the Cadillac's power and M3's steering and the general performance level of all three was outstanding with 0 to 60 arriving in around 4 second flat and the "slowest" ran a 12.5 second 1/4 mile. Here are the ratings:

Third. Audi RS5. Car and Driver appreciated the RS5's 7 speed S-Tronic gearbox and 450 horsepower V8 but its 4,000 pound curb weight along with steering modes that never achieve satisfaction put it in third.

Second. Cadillac CTS-V. Car and Driver found the CTS-V the most stable on the Autobahn and the supercharged V8 most powerful, yet a little too quiet. C/D also liked the Cadillac's steering and brakes but was disappointed by its interior and Recaro seats.

First. BMW M3. The lightest in test (3,600 pounds) M3 with the competition package had the best handling in the test. C/D also liked the M3's V8 soundtrack. The M3 was the shiftiest at high speed on the Autobahn.
