*There are differences between the 325e and 325i engines. Although both models have engines from the BMW M20 family, the 325e has more displacement than the 325i (2.7L vs. 2.5L), but less horsepower (121 vs 167). The 325e's stroker motor gives it the larger torque output, it has a higher torque rating than the 325i (170 vs 164). The "e" has a low 4800 RPM redline but basically a flat powerband and a tall 2.93 diff (2.79 earlier models) to help increased gas mileage. The sportier 325i has a shorter 3.73 diff ratio (4.10 in automatics) and a higher revving engine (redline at 6700 RPM). Compared to the 325e, the 325i has a hotter cam, dual valve springs, larger valves, larger intake manifold, larger throttle body, larger exhaust manifolds, dual pipe exhaust system.
