Compare the 2022 BMW 2-Series with the 2022 Audi A3: car rankings, scores, prices and specs. Model Year. Comparing 2 Cars. A 320i has a 2.2L 6-cylinder engine whereas my 318i has a 4-cylinder 2.0L engine.Historically, a 318i would have been an 1800cc, etc. But with the last two or three generations, what BMW has sheepishly done is to increase the 318i’s engine capacity to 2000cc, and made the 320i a 2.0 Turbo engine. When RS Audis would came up I quickly scooted out of the way, but the 320i managed surprisingly well and this is coming from someone that also runs a performance car. I suspect a 318i will be a little worse. Not enough to be bad, but just that bit to leave you wanting more. The same is true in 320i vs 330i and 330i vs 340i. GYRES.
