bmw e36 318i vs 320i 3rd gear acceleration
318i left, 320i right. E36 limousines, both 97'. Same place, same set of wheels, almost the same weight, different season (summer, autumn). 320i might have faulty oxigen sensor. Both start at 950rpm. 85kw vs 110kw. Up till ~3000rpm they both make the same power/torque according to Dyno sheets i found on the internet. The other time i videod 0-120kmh, and 318i is no match to 320i, so its not that hopeless though.
