OP, I’d split the difference and get the 330i M Sport. It’s larger, more capable, and about the same weight as an M135i. 300 lb lighter than the porky M340i. Same drivetrain as the M135i, but detuned. The BMW 330i has a three-stage variable induction system, an electric cooling pump and a volume-controlled oil pump that only pumps as much oil as needed, saving engine power. Of keen interest to Bimmer fans is the fact that both the 325i and 330i are now powered by 3.0-liter engines. The only real difference between the two is output. 330ci: can be had 3 years newer, somewhat easier to repair and maintain, coupe is sportier looking (subjective) 540i M sport manual: rare, fast, looks damn good, sedan is more functional. Tough choice, I'd probably go with the 540 if you can find one in good shape, which isn't a small task on a 9+ year old car. Reply Quote. Is the 330ci reliable? Great, reliable and affordable BMW to own Go for the older 330, and we have the convertible 330ci. Reliable, high performance and wears well over time. Which one is better E46 or E90? For example, the E46 330i ZHP offers better performance than the E90 325i. That said, in general the E90 wins the performance aspect. The 330i has enough power in nearly every situation. Especially the torque (210 Nm vs 300 Nm) makes a huge difference in the rpm regions that you use in everyday driving. The 320i does have the edge in smoothness, though. Still, both are great engines (No matter if M52TU or M54) and leagues ahead of the four cylinders, the diesels and even The top speed of a BMW 330i is 155 mph with a 0-60 time of between 5.3 and 5.6 seconds. ` The speed and prowess of the BMW 330i come courtesy of a 2.0-liter, turbocharged four-cylinder engine that produces 255 horsepower and up to 295 pound-feet of torque.
