BMW introduces their new M135i, the highest performance version of their small city car, which competes with the Audi S and Mercedes AMG lines.

BMW is putting some serious power under the hood of this latest generation 1-Series. The new M135i is a new hot hatch powered by a 3 liter, straight six that produces 320 horsepower. Good for 0-60 in 4.9 seconds and a top speed of 155 mph. The M135i will also come in a five-door variant when it hits European showrooms later this year.
