Chassis & Suspension

The ALPINA driving experience is unique - perhaps best characterised by effortlessness and powerful confidence. The intelligent suspension and chassis set-up plays a pivotal role in this by allowing high, perceptible comfort combined with outstanding driving dynamics and neutral handling. This is the oft-cited driving comfort ‘made by‘ ALPINA.

The adaptive ALPINA sports suspension combines electronically adjustable dampers with springs, auxiliary springs and anti-roll bars. Independent of the active dampers continuously adapting to the current driving conditions, the driver can also noticeably adjust the suspension and overall driving dynamics towards a more comfort or sport orientated setup.

Dynamic

Camber and toe-in settings adapted to the model-specific wheel and tyre combination, subtle elastokinematic measures and the maximum rim size ensure high directional stability, precise steering and agile handling. Every BMW ALPINA is supplied from the factory exclusively equipped with MICHELIN Super Sport summer tyres. These high-performance tyres, which are specifically matched to the respective car, are benchmark in the categories: traction, wet and dry grip and durability. The tyres on all BMW ALPINA automobiles forego run-flat technology in favour of enhanced ride comfort.

The Dynamic Performance Control button, which is used to select the different modes of the electronically adjustable dampers, also controls other parameters and features that influence driving dynamics. Depending on the equipment specifications of the particular model, this may include for example active roll stabilisation, power steering, torque distribution (all-wheel drive only) and even the driving stability control systems – the latter which are programmed with a noticeably sport-oriented setup.

Limited-Slip Differential

The mechanical limited-slip differential improves traction when driving very dynamically and inhibits wheel spin by distributing torque to the wheel with more grip. This situation may arise for example when a wheel becomes unloaded during cornering or during acceleration when the driven wheels are on surfaces with high differences in grip. When negotiating tight corners in a spirited fashion, for example in the mountains or on a circuit, but also in generally wet conditions, undesired wheel spin can occur on the inside rear wheel due to becoming unloaded in combination with high engine torque. The limited-slip differential intervenes at an early stage to prevent wheel spin from arising and therefore ensures that there is no loss in traction so that the vehicle can accelerate optimally out of the corner. Overall, the limited-slip differential leads to a significant and perceptible increase in driving dynamics, much to the delight of particularly sporty drivers. The hardware itself consists of a torque-sensing differential of motor sports quality developed in cooperation with the company Drexler. It is assembled by hand with precision-forged gear wheels and a CNC-milled housing.

 

 

Safety

A BMW ALPINA offers a high degree of comfort and sportiness as well as neutral handling, which ensures stability and a high-degree of safety even when driving at higher speeds.

The electronic driving stability control systems are specifically configured for each specific BMW ALPINA model, taking into account a plethora of influencing parameters, in order to ensure that the high power and torque are transferred to the road safely and effectively.

The influence of the aerodynamic properties of a vehicle on driving stability is of particular importance, especially at higher speeds. Based on the principle ‘Form Follows Function‘, the aerodynamic components such as the front and rear spoilers are specifically designed to work together in order to achieve the maximum possible reduction in lift and thus ensure very neutral handling.

The brake system has the task of decelerating the vehicle safely and comfortably from high speeds. Generously dimensioned with maximum utilisation of the brake surface and equipped with excellent ventilation, the brake system in every BMW ALPINA provides outstanding deceleration performance. In the interest of sensitive pedal feedback and high everyday driving comfort, conventional brake discs are used.
