BMW Alpina B5 Bi-Turbo

The BMW Alpina B5 Bi-Turbo has all-aluminium V-8 engine with sensational pace. BMW Alpina B5  be complete 507 horse power at a moderate 5,500 rpm, with maximum torque of 700 Nm from 3,000 to 4,750 rpm. The “Bi-Turbo” appellation refers to the two turbo chargers comfortably nestled inside the V shaped 8 cylinder block. They work in parallel, each feeding one of the two cylinder banks.

Specially developed for BMW Alpina B5 in partnership with Honeywell-Garrett, the bespoke exhaust engine are generously dimensioned. Compared to its super-charged predecessor, this engine configuration delivers more torque over a broader rev range and improves throttle response at low revs.

To fully leverage the potential of the engine, ALPINA have optimized the indirect inter-cooling system (air-to-water / water-to-air) with short intake tracts and increased inter-cooler flow. The high-performance cooling package gains its thermo-dynamic efficiency through the use of a large-volume low-temperature inter-cooler, as well as two water-to-air inter-coolers placed close to the engine.
