I would like to see a "Sport" mode with a bit more aggressive acceleration from a stop. While the car is more than fast enough I bet there could be a bit more performance to squeeze out without overwhelming the tires.
I'd love to see a Sport mode, too. I have the sneaking suspicion that BMW has already explored this (after all, BMW is all about driving) and for reasons of their own, have decided to forego a Sport mode -- for now.
If you were in the ActiveE program, you may recall that the early version of software did allow "Launch mode" (at the stoplight, DSC off, step on brake -and- step on the accelerator. Floor it. A checkered flag appeared in the dashboard display. Wait for the light to turn green. Release the brake pedal and hang on.)
Not long later, issues started showing up with the motor's output shaft's gear teeth (splines, actually) and the gearbox's counterpart were showing premature excessive wear and failure. BMW replaced the $30,000 motor in every ActiveE in the test program. Ow.
If you lurk on Tesla discussion threads, you may have picked up on a similar problem with the Model S: premature wear of the motor's output shaft's splines. Not as dramatic as the ActiveE, but indicative if "issues" with high-torque, low-rpm conditions on electric cars with ample horsepower.
Soooo, I'm guessing that BMW is forbidding a Sport mode until those high-torque low-rpm components are beefed up -- probably in the next generation of motor, which may exclude the i3 entirely :-(
It is interesting to see that Tesla is dealing with the same spline issues that us ActiveE drivers dealt with. In one article I read 1000 of the the Norwegian cars were recalled and I remember the Edmunds and Consumer Reports having multiple motor issues in their Teslas.
It looks like BMW experienced this in their Field Trail phase and then fixed it (fingers crossed) for the world wide launch of the BMW i3. Having the ability to do field trials is perhaps a luxury that larger OEMS can do.
I remember a lot of criticism leveled at BMW for their second field trial car the BMW ActiveE. The comments were along the lines of "C'mon man you have already done one field trial car, launch the retail version already!" But it was the second car that exposed the spline issue. So good for BMW for being deliberate and thorough.
I had a blast with the Mini-E and ActiveE, issues and all!
