It’s the punchy little m10 motor, 4 speed transmission, and incredibly low curb weight that make these cars fun to drive. You lose all that with an electric conversion.
As an aside, the most powerful F1 engine ever put on the track was made by modifying the little 4-banger m10 found in the BMW 2002. Fun fact.
Supposedly BMW lacked a dyno that went high enough so it's an educated guess what the actual hp was, but definitely over 1,300hp... from a 4-cylinder (turbo charged, and only lasted a few laps, but still) engine!
AKA the 4 speed transmission I mentioned :)
But yes, the vibration, sound, and feel of the incredibly simple (as in stripped down, not unsophisticated) mechanics around you all very much contribute to the special feeling of driving these cars.
My 1976 BMW 2002 is actually my first car. I used to drive it to high school more than half my life ago, and I still drive it today. I’ve driven some other classic cars, luxury and sport, and simply nothing feels like a 2002. Just a beautiful, balanced, timeless design.
There are so few of these cars on the road anymore that I think very little progress is to be made on emissions levels by converting them to electric, especially when you consider that you’re ruining the driving experience.
