Hot on the heels of unveiling the new M-badged M135i, BMW introduces another high performance 1-Series, this time based o the old 1er. The 2013 135is continues the tradition of “s” models, which save the M version are the most powerful member of each series. The new 135is packs 320 hp, only about 30 hp less than the much-loved BMW 1M Coupe.

Both the coupe and convertible 135is are powered by the renowned N55 TwinPower Turbo 3.0-liter inline-6 engine. It is tuned at 320 hp and 317 lb-ft of torque (+ 20hp and 17 lb-ft over the 135i), but offers the same mpg as its non-s brother. Also i the ‘s’ the engine cooling system has been upgraded to match the additional performance.

Transmission-wise, you can have the cars with either a standard 6-Speed manual transmission or an optional 7-Speed Double Clutch Transmission.

Sport suspension, high-end systems like Dynamic Stability Control (DSC) and Dynamic Traction Control (DTC), better brakes, 18-inch wheels… this car has got the lot. Just about the only thing it lacks compared to the full-fat 1M is the bespoke M differential.

The looks are different as well. The 135is looks pretty much standard, save a few details like M-sport bumpers, bigger wheels, and dual exhaust pipe. Interior highlights include stainless steel pedals, special interior badges and optional black leather seats with blue stitching for the standard sport seats.

So if you couldn’t get your hands on a BMW 1M, this thing seems to be the perfect replacement, especially as it’s cheaper. The 135is goes on sale in America this autumn starting from USD44,145 for the coupe and USD48,845 for the convertible.
