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.
Stated fuel consumption and CO2 emissions are measured pursuant to EU Regulation 715/2007 in its applicable version. From 1st of September 2018 the Worldwide Harmonized Light Vehicles Test Procedure (WLTP) has replaced the New European Driving Cycle (NEDC).
From January 2021 onwards, European Union member states are required to ensure that new passenger cars offered for sale, for lease or exhibited in showrooms or similar, are clearly labelled with consumption and emission data according to the new WLTP test cycle. Work is currently underway on the amendment of the German regulatory framework which governs the implementation of this European Union obligation in German law, its final completion however is still outstanding. For a number of new vehicles, NEDC consumption and emission values are no longer available, it is therefore reasonable that the more realistic WLTP consumption and emission values are provided to customers instead.
The official manufacturer consumption and emission values have already been determined on the basis of the new WLTP test cycle and, for some models, calculated back to NEDC test cycle for information purposes. The WLTP values are used for the assessment of taxes.
BMW ALPINA B4 Gran Coupé
Fuel consumption WLTP, combined: 10.1 l/100 km
CO2 emissions WLTP combined: 229 g/km
All technical data apply to the German market, additional international units of measure shown in the technical data for the purposes of information only. Further information on specific fuel consumption and CO2 emissions of new passenger cars is provided by the ‚Leitfaden über den Kraftstoffverbrauch, die CO2-Emissionen und den Stromverbrauch neuer Personenkraftwagen‘ which can be obtained free of charge at all points of sale and from the Deutsche Automobil Treuhand GmbH (DAT) or online https://www.dat.de/co2/.
