The Alpina B7 Bi-Turbo Is Even Faster Than Originally Thought

Alpina

Time to go supercar hunting.

When it was first revealed at Geneva in March 2016, Alpina proudly announced its new B7 Bi-Turbo had a predicted top speed of 193 mph. Turns out they were wrong, but in a good way. The Alpina B7 Bi-Turbo now has an official top speed of 205 mph. That’s incredibly fast for a large luxury sedan that’s based on, although heavily modified to Alpina’s own specifics, the latest BMW 7 Series. Alpina, of course, has altered the car to its own beat, as it does with all BMWs it works on. Powered by an Alpine-optimized bi-turbo 4.4-liter V8, total output is 608 hp.

And, for the record, being a member of the unofficial 200 mph+ club is quite an accomplishment, especially for a heavy sedan. How did Alpina pull off this feat? The V8 was heavily revised, starting with two specially-developed twin-scroll turbochargers located between the cylinder banks. Attention was also given to airflow optimization, with a new wide-bore intake system providing shorter intake paths and optimized radii to allow near-instant throttle response. Even the pistons and spark plugs were updated to Alpina’s specifications. The ZF eight-speed automatic gearbox, which can be controlled manually, received additional cooling, strengthened gear clusters and a larger torque converter.

It’s best to view the Alpina B7 Bi-Turbo as "an evolution of the latest BMW 7 Series," and it’s for those who want something a bit more special and, not to mention expensive. The interior, for example, offers an almost limitless range of options and leather trims. There’s absolutely nothing cheap inside, and the price reflects that. In the UK, that pricing begins at 115,000 GDP, or roughly $150,000 USD. The base BMW 7 Series begins at about $83,000.
