The New BMW 1 Series

BMW 1 Series
Chassis and Suspension
The BMW 1 Series is unique in its class with its front engine - rear drive layout offering near perfect 50:50 weight distribution, resulting in dynamic on-road capability. Unlike its competitors who transmit power and steering input through the same two wheels, the 1 Series leaves the front wheels to guide the car while the power is transmitted to the rear. This ensures improved grip and better traction under acceleration as the weight of the car transfers to the rear.
Once on the move, the rear-wheel drive 1 Series comes into its own, with the steering remaining uncorrupted and the car delivering a sports car-type driving experience. It is no coincidence that all serious racing cars are rear-wheel drive.
But sporty and dynamic handling can be compromised by weight. Thanks to the car's svelte 1,205kgs overall weight (116i), delivered through the use of aluminium parts, the 1 Series delivers on its promises. Much of the front suspension and subframe are made of aluminium along with the axle, suspension struts and pivot bearings. At the rear, BMW's pioneering five-link rear suspension is fitted for optimum ride quality. By replacing the traditional double wishbone arrangement with a version of the five-link set-up employed on the 5 and 6 Series, engineers have been able to subtly alter the toe-in, toe-out and camber angles for increased cornering ability.
For drivers wanting an even sportier ride, the new BMW 1 Series can be specified with sports suspension that lowers the car by a further 15mm. This not only gives the car a more aggressive stance but also adds to the performance characteristics by giving a more agile ride.
Transferring the chassis abilities and engine performance to the road is the responsibility of the car's Run-flat tyres. The 1 Series comes as standard with 16-inch wheels and Run-flat tyres, banishing roadside tyre changes to history. For those wanting to personalise their car, a variety of optional 16 or 17-inch alloy wheel designs are available as factory-fit or dealer-fit accessories.
