BMW built much of its early reputation on small, nimble, fun-to-drive vehicles. For decades, BMW's smallest offering in the United States was the 3 Series-a model that has grown in size and weight to proportions more commonly associated with the larger 5 Series. For 2008, BMW offers the 1 Series: a smaller, lighter, and more nimble vehicle. Its appearance is dramatically different from any BMW model intended for U.S. markets in recent years, but the design is still unmistakably that of a BMW.

Model Lineup
Consumers can choose between two different BMW 1 Series models for 2008, both 2-door coupes. Most of the significant differences lie in the powerplant, and in a few optional pieces of equipment. The 128i offers the less potent of the two engine choices, but has a full complement of standard power features and amenities. The more powerful performance-oriented 135i is offered with standard Xenon headlamps and an M-division Aerodynamic Kit. The 135i also offers larger multi-piston brakes, and 18-inch wheels.

Options on 1 Series models include leather seats, Active Steering, and a Sports package (upgraded seats, wheels, tires, and suspension-standard on the 135i, optional on the 128i). iDrive, BMW's all-in-one solution for control of navigation, audio, communication, and climate settings, is also available on both models. It has been updated for 2008, with six programmable memory keys for more intuitive functioning. A 60/40 split rear-folding seat, with Lower Anchors and Tethers for Children (LATCH) attachments for safer child seat installation, is standard on both models.

The 2008 BMW 1 Series is offered with a choice of two different inline 6-cylinder engines powering the standard rear-wheel-drive platform. The 128i is motivated by a 3.0-liter 230-hp powerplant with 200 lb.-ft. of torque. The 135i enjoys a twin-turbo 3.0-liter engine with 300 hp and 300 lb.-ft. of torque. Both models are equipped with independent suspension on all four corners, with an extensive use of aluminum for rigidity and weight savings. The BMW 1 Series is offered with "BMW Ultimate Service," a program that includes a 4-year/50,000-mile new-vehicle warranty, and, according to BMW, the only no-cost maintenance program in the industry (for 4 year/50,000 miles). As of this writing, EPA fuel economy figures had not been released.

In addition to standard electronic safety aids such as anti-lock brakes, traction control, and stability control, the driver and passenger in the 2008 BMW 1 Series are protected by front and side air bags. All occupants are shielded by curtain air bags that extend the length of the passenger cabin. The seats inside the 1 Series are of a special "crash-optimized" design with padded headrests and backrests to significantly reduce the risk of injury from a rear impact. The 1 Series has not been crash tested by the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS).

The twin-turbo powerplant of the 2008 BMW 135i features special direct piezo gasoline injectors designed to release the proper amount of fuel into the engine for efficient combustion. The result, BMW claims, is better engine response and improved fuel economy. BMW's Dynamic Stability Control (DSC), standard on both 1 Series models, has been specifically tailored for the performance-oriented 135i. Under certain conditions, DSC is able to simulate a limited-slip differential lock for stronger acceleration in turns. Radio options include Sirius satellite radio, HD radio, Premium Sound, and Bluetooth. While a USB port is an option, an auxiliary jack is standard for connecting an external MP3 player to the stereo system.
