The only other car with a bumper like this is the X2 in one specific trim level, M Sport X. The body kit will basically be the same for the M135i, but the brakes are too small for that model. The M Performance grille with the same mesh as the Z4 M40i is also missing. Instead, based on the shape of the exhaust muffler, we believe we're dealing with the 118i.
According to some recently leaked specs, this will use a 1.5-liter 3-cylinder turbo to deliver 140 HP. This direct rival to the Mercedes-Benz A 180 and Audi A3 35 TFSI should come with BMW's DCT and will get to 100 kph (62 mph) in about 8.5 seconds. At launch, your only other powertrain option will be the 190 HP 120d, though more are obviously coming.
The flagship 1 Series has already been confirmed to be the M135i with a 2.0-liter boasting 306 HP and 450 Nm (332 lb-ft), giving it a 0 to 100 kph time of well under 5 seconds. At this time, BMW is not working on anything to rival the A45 and RS3.
The main advantage of using this FWD platform is interior space. Within the same footprint, BMW will offer more legroom and a larger trunk while also reducing the weight. However, the architecture is also better suited to being a plug-in hybrid with the battery tucked away at the back and within the tunnel.
