The 2015 BMW 335i xDrive will not disappoint with quick acceleration and a good sounding exhaust note. The familiar 3.0-liter turbocharged I6 engine still delivers 300 horsepower and 300 lb-ft of torque. However, the damp test track is not ideal for getting the best acceleration times or other performance measurements. It’s not fair against other cars we tested.
Still, there are questions about different ways of measuring acceleration and the new VBOX Sport device can answer them after just a few button clicks. Americans measure 0-60 mph with and without a 1-foot rollout. Europeans and other regions around the world, measure 0-100 kph without the rollout.
First, the 1-foot rollout (actually 11.5 inches) is made popular by the drag racing community. This is the distance between where the leading edge of the front tire crosses the laser beam (the second beam at the drag strip) and where that tire rolls out of the beam, thus starting the timer. It means the car can travel around 11.5 inches forward without being timed, thus getting a better result.
The fastest time we got was 6.17 seconds for a 0-60 mph. We know the 335i is quicker than this even at a mile above sea level. We got a better result with the 2013 model. However, the wet track conditions did not allow us to get the best time possible.
What are the differences? Lets find out. Check out the video for all the behind-the-scenes action.
