Alpina has revised the top speed of the new BMW
7-Series-based B7 Bi-Turbo, just in time for the model’s UK launch. The final specification of the new
super-saloon pushes the
top speed to a very impressive 330 km/h, up from the predicted 310 km/h figure that was announced at the model’s debut at the last Geneva
Motor Show.
Power comes from a heavily reworked version of BMW’s
twin-turbo 4.4-liter V8 which now makes 600 hp and 800 Nm,
courtesy of the specially developed twin-scroll turbos which deliver up to 1.2
bar of boost pressure with minimal inertia.
Alpina has also added a new indirect intercooler
system (air/water/air), featuring a main intercooler feeding two large and
close-coupled intercoolers and additional radiators, to make sure that the
twin-turbo V8 will be thermodynamically stable at all times.
The ZF eight-speed automatic transmission has also
been upgraded with additional cooling and a range of modifications that include
strengthened gear clusters and a larger torque converter.
B7 Bi-Turbos that are destined for the UK market
will be rear-wheel drive, long-wheelbase models equipped with air suspension,
Active Roll Stabilisation and Alpina’s active rear steering. The variable ratio
electric steering also gets a bespoke calibration while the front wheels
benefit from an increased camber for a more direct turn-in. 0-60mph will come
in 4 seconds flat.
Alpina has achieved this alongside
superb ride quality and refinement at lower speeds, and all for just £ 115,000.”
