BMW ALPINA B4 GRAN COUPÉ

Powertrain

Engine power

The straight-six cylinder engine generates 364 kW (495 hp) of power and a maximum torque of 730 Nm (538 lb-ft) from 3.0 litres of displacement and two mono-scroll turbochargers.The power delivery is effortless throughout the full rpm range, which is a hallmark of the superior driving experience for which ALPINA is known.

The engine is fitted with ALPINA specific flow-optimised turbine housings to effectively convert exhaust gas energy into boost pressure at low engine speeds. The large intercooler increases the efficiency of the charging system. An optimised air intake duct with large-volume air filter housings aids engine response.

 

 

ALPINA sport exhaust system

The BMW ALPINA B4 Gran Coupé exhaust system combines close-coupled catalytic converters and underbody catalytic converters with two gasoline particulate filters. To reduce the exhaust back pressure, the ALPINA engineers rely on wide diameters in the exhaust system as well as large cross section particulate filters.
