Perfect handling: high-quality suspension technology, even weight distribution and improved stability control

The new BMW 1-Series boasts best-in-class suspension technology, with a double-joint cross-strut front axle with McPherson struts and sway bars, and a five-link rear axle. The high aluminium content of the front axle structure effectively reduces the unsprung mass, while noise levels have also been reduced and crash performance improved.

Both the front and rear axles have double elastic bearings and extra-large bearing blocks for increased comfort and responsiveness. The new BMW 1-Series has a wider track than its predecessor (51 millimetres wider at the front, 72 millimetres wider at the rear), and the almost perfect 50:50 weight distribution helps to translate the dynamic advantages of the rear-wheel drive layout into an exciting and agile ride.

The new BMW 1-Series has electromechanical power steering as standard, combining typical BMW precision with very low energy consumption. The optional Servotronic function provides speed-dependent power assist. Variable Sport Steering, also available as an option, reduces the number of steering wheel rotations required to make sharp turns. In this mechanical system, steering ratios are adjusted using a variable steering rack. Parking and turning are safer and easier, requiring minimal steering effort, but the typical BMW steering precision and directional stability at high speeds are maintained.

As an alternative to the standard 16-inch wheels, the new BMW 1-Series is also available with 16, 17 and 18-inch light-alloy wheels. Its responsiveness and powerful braking in emergency situations are partly due to DSC Dynamic Stability Control, and the car also has ABS anti-lock braking, DTC Dynamic Traction Control, CBC Cornering Brake Control and DBC Dynamic Braking Control. Other features now include braking assistance, fading compensation, brake drying and hill assist.

DTC mode increases the intervention thresholds of DSC, making it easier to drive on loose sand or deep snow. By allowing slight slippage of the drive wheels, it also facilitates controllable oversteer. DSC Off mode activates the electronic rear axle differential locking system. If either of the drive wheels suffers wheelspin while accelerating through tight bends, brake force is applied to this individually, so that the opposite wheel maintains traction.
