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 is also offered. The 135i competes with performance cars like the Nissan 350Z and Volkswagen R32.

New for 2009
New features include a heated steering wheel available on models with the Cold Weather Package, plus a new iDrive control feature on navigation-equipped 135i models. Also new on models with the nav system is a Google Maps feature that allows users to search for restaurants, gas stations, etc. using Google's database.

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.

  • 18-inch wheels standard on coupe, available on convertible
  • Heated side-view mirrors and heated windshield washer jets
  • Rain-sensing wipers
  • Convertible features power-operated soft-top that BMW says can open or close in 22 seconds
