Why it matters
On its 1989 launch the B10 BiTurbo was considered the most powerful series-production saloon in the world, pairing a twin-turbocharged 3.4-litre six with a BMW 535i body. Only 507 were built, each with its own consecutive Alpina production number.

Every figure says what it counts.

| Total model productioncars built Sept 1989–March 1994 | 5071,2 | Factory production | Independently researched |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
Alpina based the B10 BiTurbo on the E34 535i, fitting its B7/5 engine with two water-cooled Garrett T25 turbochargers whose boost the driver could adjust. A Getrag five-speed gearbox designed for the car and an M5 limited-slip rear axle handled the 360 PS. Production ran from September 1989 to March 1994, totalling 507 cars, and the car's title was later taken by the Lotus Omega and others.

06Reference
Identification guide
How to tell an original from a replica or later conversion.
Each genuine car has its consecutive production number stamped into the right-hand front shock-absorber dome and on a silver-plated plaque on the centre console; these should match. Mechanical clues include twin Garrett T25 turbochargers and the Getrag type 290 five-speed gearbox.
