Vehicle Overview BMW's small 1 Series debuted in the U.S. for 2008 as a coupe and a convertible. The up-level 135i is powered by a 300-horsepower, twin-turbo inline-six-cylinder engine that drives the rear wheels. A less expensive 128i covered separately in the Cars.com Research section is also offered. The 135i competes with performance cars like the Nissan 370Z and Audi TT.
New for 2010 The only changes of note are that HD radio becomes standard and automatic high-beam headlights are a new stand-alone option.
Exterior Compared to the 3 Series coupe, the 135i features a more upright grille and a C-pillar that's not as sleekly styled. A pronounced sheet metal crease runs the length of the coupe's sides, which are otherwise relatively smooth.
