I dunno... For direct drive, I'd say that AC-50 would be good for a lightweight (say ~800kg) car, but for a 1500kg car it'll be pretty anemic without a gearbox, especially at takeoff. Assuming your ratio puts the hp peak at 60mph, you're looking at what, 6hp at 5 mph?

If you had a 5-speed in there, you could be seeing around 40-50hp at that speed, much more fun
