Is it the car, us, or a little of both? Our 2011 528i has less than 1,000 miles, so we are still novice BMW owners. That said, neither my wife nor I have been able to adapt well to its accelerator. Specifically, we are having difficulty making smooth, moderately quick starts from a standstill. Slow, rolling starts are not a problem. Neck-snapping, tire-chirping starts are also easy to do. I read on a BMW blog from Canada that they were complaining about the 2011 528i accelerator pedal needing too much travel to get quick acceleration. I'm wondering if BMW heard the Canadian complaint and over-corrected on the side of too little travel for quick acceleration for the USA market? We drove Audi's for 20 years and turbo Subaru's the last 3 years. We did not have this problem with those cars. Since the system is drive-by-wire and programable, we wondered if modifications were available and/or authorized by BMW?
