2020 BMW M340i xDrive review

It’s only a couple of generations since a typical BMW 3 Series was more likely to come with a six-cylinder engine than a four-pot, and the mighty M3 was still packing a glorious, naturally aspirated V8. No longer. The new 2020 BMW M340i is the first petrol G20 with more than four plug leads, and the only other six-cylinder in the line-up will be the M3 that this car understudies for.
