BMW ALPINA B4 GRAN COUPÉ

Chassis

ALPINA Sport Suspension

A negative camber of 1.25° at the front axle in combination with specially developed front-axle anti-roll bars increase lateral dynamics significantly. A bespoke spring and damper configuration ensures balanced suspension characteristics and the specific adaptation of the variable damper control ensures a noticeable differentiation between the various driving modes.

Variable sports steering

The variable sports steering offers direct steering feel and feedback. The driver can choose between three steering modes: COMFORT mode offers balanced directional stability with a good safety feeling into the higher-speed range, while the two SPORT modes are characterised by substantially more direct feedback.

Ultra-high performance tyres

The Pirelli P ZERO ultra-high performance tyres offer high levels of grip and lateral support. The manufacturer code ALP on the tyre flank indicates that this is a custom tyre developed specifically by Pirelli for ALPINA. During the development process equal emphasis was placed on ride comfort and dynamic characteristics.

 

 

Safety reserves

The brake system has been dimensioned with the handling potential of the BMW ALPINA B4 and a top speed of 301 km/h (187 mph) in mind. Four-piston fixed brake callipers with Ø 395 mm (15.6") brake discs at the front axle and floating brake callipers with Ø 345 mm (13.6") brake discs at the rear axle offer generous safety reserves. The optional high-performance brake system* with drilled lightweight composite brake discs offers more precise pedal feedback and thermodynamic reserves.

*Please note that drilled brake discs may lead to a loss of acoustic comfort.
