Think this is a classic case of “which one doesn’t belong”? Think again. The guys at ASR spent a good amount of time tweaking the baby Bimmer to fighting form, and the result is a car capable of besting even the mighty GT-R. The 135i packs 540 horsepower and 538 lb-ft of torque at the wheels. Even better, ze BMW’s competition is far from stock, with the Porsche rocking a full 510 ponies and Nissan’s finest bringing 540 horsepower to play with. Hop the jump for a look at the cars going head to head. [Source: 0-60]
