Chassis technology that delivers driving pleasure
The new BMW 4 Series Coupé utilises an enhanced version of the 3 Series Saloon chassis to offer improved handling and reinforce its sporting character.
An almost completely sealed underbody, improved air flap control and numerous other measures have led to a reduction in drag, reflected in a Cd as low as 0.25 (BMW 420d Coupé). The extra 23 millimetres of track width at the rear axle compared with the new BMW 3 Series Saloon, 50:50 weight distribution and a centre of gravity that is 21 millimetres lower than the Saloon significantly aid agility.
Customers can tailor the driving experience with options that include M Sport suspension, Adaptive M suspension with variable sport steering, M Sport brakes and the M Sport differential.
Stiffened body structure and suspension mountings
Targeted measures for increasing the stiffness of the body structure and suspension mountings strengthen the distinct driving qualities of the new BMW 4 Series Coupé. Model-special features include a shear panel for connecting the front spring strut towers to the bulkhead and integral tower-to-front end struts. Bracing elements have also been added to increase stiffness in the rear axle area.
Weight-minimised axle design, lift-related dampers with specially tuned characteristics
The design principle of a double-joint spring strut front axle and five-link rear axle offers an outstanding basis for combining precise handling with impressive long-distance comfort.
The standard lift-related dampers aid performance and comfort, reducing body movement on bumpy road surfaces as well as improved handling on cornering.
Increased damping forces, firmer springs and anti-roll bars have been employed to give the new BMW 4 Series Coupé supreme handling characteristics. The M Sport suspension, standard across the range, includes stiffer settings for the lift-related damping and the likes of additional body struts, more rigid mounts, firmer anti-roll bars and increased negative wheel camber.
The optional Adaptive M suspension combines all the qualities of M Sport suspension with electronically controlled dampers. Continuously adjustable valves allow the damping force to be metered at each wheel individually and as a function of vehicle load. Switching between the various Driving Experience Control switch modes produces a clearly perceptible variation in the damping characteristics.
An extra mode can also be selected using the Driving Experience Control switch on models with Adaptive M suspension. In the ADAPTIVE setting, the steering, damping and accelerator responses along with the Steptronic transmission’s shift characteristics are automatically adjusted to suit the driving style.
Electric Power Steering including Servotronic speed-sensitive power assistance is fitted as standard. Variable sport steering, with a ratio that adjusts to changes in the steering angle, is part of the M Sport suspension and Adaptive M suspension set-ups.
M Sport models come with 18-inch M light-alloy wheels whilst M Sport Pro package upgrades to a 19-inch M light-alloy wheels. M440i xDrive Coupé and M440d xDrive Coupé are fitted as standard with unique Cerium Grey Double Spoke 19-inch light-alloy wheel. 20-inch light-alloy wheels for the new BMW 4 Series Coupé are available from the Original BMW Accessories range.
