Chassis & Suspension

Dynamic Comfort

The times when overly stiff suspensions were seen as a positive handling characteristic are long gone. It remains a fact that a truly neutral set-up, even at the limit, provides the best technical compromise.

This is achieved in part through shorter ALPINA springs, greater camber at the front and subtle changes to the toe in. Together with 20“ wheels and tyres this yields a very balanced and direct chassis set-up, discarding a pure sport-orientated approach for an agile suspension with precise turn-in.

Mounted on lightweight ALPINA CLASSIC wheels are non-run-flat MICHELIN PILOT SUPER SPORT tyres measuring 255/35 ZR20 front and 285/30 ZR20 rear. Representing the latest in ultra-high performance tyre technology available today, they feature a running surface which is made up of 2/3rds soft compound (centre) and 1/3rd hard compound (outside and flanks). This mixture makes for excellent durability despite typical hard use in high-performance vehicles, yet provides very good grip in the wet. Enhanced tread stability and a new flank reinforcement technology ensures the tyre is less likely to suffer from spikes in temperature with a resulting loss of grip in the dry.

To fulfil the seemingly contradictory demands for comfort, everyday usability and dynamic handling, the D5 Bi-Turbo is equipped with electronically-adjustable dampers (Variable Damper Control). This system has been artfully calibrated by ALPINA, and is tied into other system parameters controlling steering assistance, torque cushioning and the Dynamic Stability Control system.

Featuring pronounced Comfort+, Comfort, Sport and Sport+ settings, the D5 Bi-Turbo transitions effortlessly from cultivated luxury to thoroughbred sportiness. Light steering, ultra-comfortable suspension and an imperceptibly shifting transmission make the D5 Bi-Turbo an ideal partner in stop-and-go traffic, when covering great distances or when encountering less than perfect road surfaces. Yet at the touch of a button, the D5 Bi-Turbo will track through tricky corners and along exciting sections of road with an agility and light-footedness like no other in its class.
