New 600 hp Alpina B7 Bi-Turbo super saloon to be launched at Geneva - performance, ultimate luxury, comfort and quality all in one package
A new supersaloon that will reach 100 km/h in just 4.0 seconds and push on to 310 km/h will be revealed by Alpina at the 2016 Geneva autoshow next month. With an Alpina-optimised 4.4-litre V8 delivering a remarkable 600 hp and 800 Nm (available from 3,000 rpm!), the new B7 Bi-Turbo will be the most powerful and most luxurious model in the bespoke vehicle manufacturer’s range.
One of the keys to this combination of comfort and handling is maintaining the lowest appropriate weight, complementing BMW’s investments in ground-breaking light weight technologies such as the new, high-strength Carbon Core, in which the vehicle’s A-, B- and C-pillars, the transmission tunnel and the windscreen header are all made from carbon fibre composite. It will also have air suspension, Active Roll Stabilisation and Alpina-tuned active rear steering, which turns the rear wheels a maximum of three degrees the opposite way to the front wheels at low speeds and the same way at higher speeds. Then, to keep both sprung and unsprung weight down, the B7 Bi-Turbo will be available only in rear-wheel drive guise.
ALPINA has also invested considerable expertise in the engine. The highly-responsive, direct injection V8 uses two specially-developed twin-scroll turbochargers located between the cylinder banks, operating in parallel to deliver up to 1.2-bar with minimum inertia. An indirect intercooler system (air/water/air) further improves both power and responsiveness, with a main intercooler feeding the two large-volume close-coupled intercoolers. Together with additional radiators, the system ensures the thermodynamic stability of the V8 Bi-Turbo engine at all times, even under the highest sustained loads and most aggressive ambient air temperatures.
Alpina’s work on the eight-speed automatic transmission is another reason for the exceptional acceleration of the new B7Â Bi-Turbo: The result of extensive analysis and strengthening to ensure durability to high mileages - even with the very high torque output of the V8 Bi-Turbo engine. chassis electronics specialists have developed their own calibration for the Dynamic Traction Control system to ensure that the characteristics of the engine and transmission can be fully exploited for maximum performance and driver enjoyment.
Inside, the new B7Â Bi-Turbo can be specified with an almost limitless range of options. Standard equipment includes high-end Nappa leather, a leather-covered instrument panel, ceramic applications on selected control elements, soft close doors, a full-colour Head-Up Display and a rear view camera. The driver’s connection with the car and its dynamic performance is enhanced by a sports steering wheel, hand-finished in exceptionally high-quality 'Lavalina' leather with stitching in Alpina Blue and Green. Door sills are enhanced by Alpina Blue illumination of the B7 model inscriptions coordinating with interior Alpina Blue mood lighting features.
