Alpina BMW B5 Bi-Turbo




Alpina BMW B5 Bi-Turbo
The Powertrain - First Class in both Performance and Economy

First introduced in the BMW B7 Alpina Bi-Turbo, the all-aluminum V8 powerplant endows the new B5 Bi-Turbo with sensational pace. It achieves 507 horsepower (373 kW) at a moderate 5,500 rpm, with maximum torque of 700nm from 3.000 to 4.750 rpm. The "Bi-Turbo" appellation refers to the two turbochargers comfortably nestled inside the V shaped cylinder block 8. They work in parallel, each feeding one of the two cylinder banks. Specially developed for Alpina in partnership with Honeywell-Garrett, the bespoke exhaust turbines are generously dimensioned. Compared to its predecessor super-charged, this engine delivers more torque configuration over a broader rev range and improves throttle response at low revs.
