I have a Step 330XI and have raced a few new V6 Honda Accords myself. I raced a v6 auto coupe from about 40-50 mph and it seemed to SLOWLY be pulling away from me, up to 70 mph. I didnt really expect to beat him, but i was of course upset that a HONDA ACCORD was pulling away from my precious BMW. Weeks later, i managed to line up a v6 sedan at a stoplight and took him by 2-3 cars, noticing my car gets a big jump to 30 mph bc of AWD traction while his front wheels are spinning alot at the start. From 30 mph on the Accord sedan does manage to gain ground but at 80 mph i remain 2 cars ahead. As far as the coupe, im waiting to catch one at stoplight. My guess is that a manual with a good driver would beat my auto 330xi, but an auto would be a nice race. Auto accords, coupe and sedan, from what ive read run 0-60 anywhere about 6.6 (coupe) and 7.0 for sedan. Ive hand timed my 330xi, with 1 passenger, and consistently got 0-60 of around 6.65-6.9, on 3 different flat open roads.
Ill race my 330xi against an auto accord ANY DAY. the Manual, now thats another story.
