on a private test track of course,
was pretty even all the way really, several times we had to slow down and re-accelerate up to impressive speeds, and one point we lined up alongside, i was in manual sport and it when i booted it kicked down and lost me a few seconds he got a car length ahead but the gap remained unchanged upto some high speeds
thought they were limited to 155???
getting more impressed with the 335d all the time, she be a quick beast
