Bimmer 1 Series Moves to the Front

BMW AG took the wraps off the redesigned 1 Series small car, which is moving to a front-wheel-drive platform from its former rear-drive layout.

The modular FAAR architecture is a modified version of the fwd UKL chassis that carries the X1 and X2 small crossover vehicles and Mini Countryman. The new 1 Series is slightly smaller than its predecessor. But BMW says the fwd layout—and transverse engine mounting with a lower transmission tunnel—provide more interior space, yielding an additional inch of rear seat legroom and nearly an extra cubic foot of cargo space.

BMW’s research indicates that 1 Series customers prefer such roominess over the handling benefits associated with rwd models. But the carmaker tried to minimize any performance drop-offs with yaw control and an improved stability control system to prevent understeer.

The new model, which is available only as a five-door hatchback, also is about 30 kg (66 lbs) lighter than its predecessor. Other gains include a multi-link rear suspension and increased torsional stiffness. All-wheel drive is optional.

Buyers can choose among five 3- and 4-cylinder engines, including three diesel mills, that range in output from 114 hp to 302 hp. The previous inline-six engine has been dropped to enable transverse engine mounting.

The gasoline engines are teamed with a 7- or 8-speed Steptronic automatic transmission. A 6-speed manual is available in the diesel-powered models.

A variety of driver-assist technologies also are offered, including adaptive cruise control, lane-departure warning and assist, blind spot detection and rear collision and cross-traffic alerts. A new reverse assist feature can automatically back the vehicle as far a 160 feet along the same path it took when it last traveled forward.

The new 1 Series is compatible with BMW's new digital key and over-the-air software updating systems. Options include a digital instrument cluster, head-up display, power-operated hatch and gesture recognition controls.

BMW will publicly unveil the model this summer. Sales in Europe and Japan are due to start by year-end. There are no plans to offer the 1 Series in the U.S.
