The last time I lined up with a guy driving a Z4M Roadster, he thought he would easily walk away from my 335d sedan. We took off and he chirped his tires, frantically revving his engine through the gears, as the 335d effortlessly pulled away from him, riding the huge tidal wave of torque. With a simple JBD module, I have achieved high 12 second qtr mile times, and 0-60 in 4.5 seconds. With this simple 10 minute modification, this car will easily out accelerate any stock petrol 335i. Look how effortlessly the car accelerates from 0-40mph in one big surge. You are doing the speed limit in the city almost instantly. And this is with a 2nd gear launch! Drove 52miles to LAX this weekend. With 4 people in the car and the A/C running, got 47mpg. On the way back with some stop and go traffic, I still averaged 45mpg. Is there any other 3800LB+ car made that can get 45mpg and run 12 second qtr mile times??? Any car?? Thats how significant diesel performance can be..
