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 new 300-horsepower inline-six-cylinder engine with one turbocharger instead of two 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 2011
In addition to the new 3.0-liter engine for the 135i, an optional seven-speed dual-clutch automated manual transmission replaces the six-speed automatic. BMW also added some features to option packages.
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.
