Diesels have their biggest advantage during the launch, and before you hit 60mph. That said, on the same testing spot, I have Vboxed a modded M3, tuned 335is, and my JBD 335d. Fact is, the two other cars trapped faster than mine, but didn't break into the 12 second qtr mile range. My 335d did. So, from a standstill, around town, etc, a 335d can definitely give a M3 driver a run for his money especially if he is fighting traction. Hitting a uphill on ramp, full of passengers is where the 335d shines with all the torque. Its insane how effortless it is with almost 500lbs of torque. FYI, the JBD is a simple module that takes 10 minutes to install, and costs a couple hundred dollars. Here is a video of mine running 0-60 in 4.5 seconds even having to shift into 3rd before 60mph...look how effortless it is even starting in 2nd gear!
Also, my best mpg on a 100 mile trip to and from LAX was over 45mpg.
Definitely a blast to drive around town, especially hearing someone trying so hard, shifting through the gears at high revs, trying to keep up with you.
see this video of my car running the qtr mile in the 12's, 0-60 in 4.5 seconds.
