There is a
You Tube video of a 35i flat out acceleration run (Sport Mode). This appears to be a pretty quick 35i.
Since I haven't seen a published acceleration curve for a 35i, I did a frame-by-frame analysis and extracted the speed/time curve.
The values are from the speedometer readings, so if this is a typical 35i, they are probably about 1.5% to 2% higher than the real speeds. This 35i reached an
indicated speed of 255kph in 69 seconds (in 6th gear).
Note, the plotted time is not the You Tube video time, but is the actual time from the start of acceleration as indicated by the speedometer. Graphed data points are at 1 sec. intervals up to 29 seconds.
