There is no shortage of powerful models in the BMW line, but sometimes buyers have a legitimate question — is it worth overpaying for a factory “charged” model, or can you buy a less powerful and more affordable car, and then resort to third-party tuning to increase the engine output and compete with the creations of factory engineers? The answer to this question was sought by the authors of the Officially Passed channel, who brought together a BMW M3 sedan and a BMW M240i coupe in one straight race.
BMW M3 Competition has a 510-horsepower (650 Nm) 3.0-liter inline turbo engine under the hood, the thrust from which is transmitted to the rear axle via an 8-speed automatic. The sedan weighs 1,730 kilograms.
The BMW M240i coupe is lighter — 1,690 kilograms — and is equipped with a 3.0-liter 6-cylinder engine with a capacity of 374 horsepower with a torque of 500-newton meters, which is combined with a similar 8-speed automatic transmission. Both models are all-wheel drives.
But in comparison with the Officially Gassed standard 510-horsepower M3 Competition, the 450-horsepower M240i was already opposed, retrofitted with a new intake and exhaust tracts, as well as a new engine control unit. The stock sedan and the tuned coupe were compared in the starts from the spot and also evaluated their acceleration dynamics in motion. It turned out that each variant of BMW has its advantages in different modes of racing in a straight line.
