Steve Dinan really wants to tune the BMW i8. He and his team sat down to hatch a plan, but it was scrapped in short order. By turning up the electric wick on BMW's hybrid super coupe, the life of the battery would be decimated. And that's a problem when the 7.1 kWh pack costs upwards of $10,000.
Putting warranty issues aside for the moment, boosting the performance of everything from the i8 to the Nissan Leaf is wrought with challenges.
