Performance numbers for the M276 3.5 liter direct injected V6 in the SLK350 from Insideline - email@example.com
Insideline has tested the new SLK350 with the M276 3.5 liter direct injected and naturally aspirated V6. The motor is rated at 302 horsepower and 273 pound-feet of torque. The car ran a respectable 13.8@101 in the 1/4 mile although we expected a little more out of this new motor. The previous generation SLK350 with just 268 horsepower was tested by Car and Driver at 13.8@103 making the performance numbers for the new car and new motor a little disappointing. The new car is about 150 pounds heavier but the new motor should have easily offset that.
