2017 BMW M240i vs. M235i Autobahn Acceleration Comparison Gets a Bit Puzzling

This isn't a back-to-back test and with the cars having been driven on different occasions, you can expect all sorts of inconsistencies. In fact, it seems like the M240i might've had to deal with dirty roads, as you'll notice the car it replaces actually beats it during the first half of the speedometer.

For the record, according to BMW, the B58 alows the almost-hot 2er to shave 0.2 seconds off its 0 to 60 mph (96 km/h) time.

Even so, going past that point reveals a noticeable sprinting difference between the M Performance sportscars and this is where the juicy part of the video lies.

In fact, this clip reminds us of the one comparing the M240i to the M2, which came with the same type of questions, but once again managed to keep us on our toes.

As noted in the clip, the 2017 model year didn't just see BMW squeezing some extra oomph from the N55 straight-six of the M235i. Instead, the M240i packs a new B58 3.0-liter unit, which might keep the configuration of the engine it replaces, but adds 15 hp and 39 lb-ft. The resulting 335 hp and 369 lb-ft of twist poses a serious threat to the M2, which allows the driver to play with 369 hp, but packs the same 369 lb-ft of torque.

Things will change next year, though, when the mid-cycle revamp is set to hit the 2 Series (call this LCI - Life Cycle Impulse - in Bimmer talk). Nothing has been officialy confirmed yet, but we've seen "civilian" 2er prototypes and as for the M2, this is where things get complicated.

The rumor mill talks about BMW introducing the 2018 M2 facelift next year, while bringing us a 2019 M2 CS (Club Sport) track-friendly version one year later. And we'll return with more news on this Nurburgring-infused topic as soon as we get our hands on them.
