Meet the 205mph Alpina B7 Bi-Turbo – an epic high-performance sports saloon based on the superb new BMW 7 Series.
Now available in the UK, the luxurious B7 develops 600bhp from its 4.4-litre V8, giving it a 0-62mph time of just four seconds. That’s Porsche 911 R, Nissan GT-R, McLaren 570GT territory.
Priced from £115,000, the Alpina B7 Bi-Turbo builds on the strengths of the acclaimed BMW 7-Series which already includes a state-of-the-art lightweight platform with A, B and C pillars, the transmission tunnel and the windscreen header all made from carbon fibre composite.
UK spec B7s will be long wheelbase cars with air suspension (allowing ride height to be automatically reduced by 20mm in Alpina Sport+ Mode) and Active Roll Stabilisation (with new light weight, high-speed electro mechanical actuation).
They will also feature 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.
At the front, there is a new calibration for the variable ratio electric steering and increased wheel camber to provide a more direct turn-in when cornering.
At the heart of the new B7 Bi-Turbo is a heavily-revised, direct injection V8 breathing through two specially-developed, twin-scroll turbochargers located between the cylinder banks, operating in parallel to deliver up to 1.2 bar with minimum inertia.
Particular attention has been paid to airflow optimisation, with a new wide-bore intake system providing shorter intake paths and optimised radii to allow near-instant throttle response. Pistons and spark plugs are uprated to Alpina specifications.
A new 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.
“Not long ago, only the most focused million pound hypercars could touch 200mph. Where road conditions allow, owners of the new B7 Bi-Turbo can cruise long distances at that legendary speed. with friends and family in considerable comfort,” says Alpina GB’s Gary Lott.
“Remarkably, Alpina has achieved this alongside superb ride quality and refinement at lower speeds, and all for just £115,000.”
