Alpina BMW B3 Bi-Turbo
From Alpina press: The heart of the B3 Bi-Turbo offers 265 kW (360 hp) at 5,500 - 6,000 revolutions per minute, as well as maximum torque of 500 Nm from 3,800 - 5,000 rpm. The B3 Bi-Turbo’s engine has a sporty engine’s willingness to rev to 7,000 rpm. Equally as present but usually reserved for diesel engines, there is vigorous torque from 1,500 rpm onwards. The result: a powerband broader than ever before experienced, guaranteeing both sporty and bullish driving dynamics.
Technically, this is all made possible due to the exceptional BMW base engine with injectors centrally located over the pistons – the state-of-the-art in direct injection technology. For more than a year, ALPINA engineers researched, developed and tested, both on the engine test bench and on the road. Ever refining the ALPINA engine map to leverage all the advantages offered by modern direct injection, the potential inherent in the BMW foundation was maximized. The use of extremely durable MAHLE pistons allows for a maximum boost of 1.1 bar with a 9.4:1 compression ratio. The result, peak specific values of 89 kW (121 hp) per liter and a maximum average pressure of 21 bar.
The allure of the new BMW ALPINA B3 Bi-Turbo is found in its V8 like performance, but with the advantages of a much lighter and noticeably thriftier 3.0-litre straight-six, a six with an aluminum block and twin-turbo charging. The smooth-running nature inherent in this engine concept is even more prominent when the engine is charged.
The BMW ALPINA B3 Bi-Turbo embodies pure driving enjoyment – whether cruising along or enjoying all 7,000 revs in each gear. The reason for the spontaneous responsiveness of the B3 Bi-Turbo is the ZF 6-speed sport automatic transmission with its very short shift sequences, which smoothly processes the power through the drivetrain without any uncomfortable interruption of forward momentum. The driver may also choose to shift manually at the wheel using SWITCH-TRONIC, which contributes in no small part to both the awe-inspiring performance numbers and the ability to save fuel in top gear. Frugality and driving excitement are therefore not contradictory in the B3 Bi-Turbo. Driven by high torque means using sixth gear on the Autobahn is more than sufficient in almost all situations.
The engine’s kick surprises even those in the know: 0-100 km/h in 4.9 seconds and thrust-like acceleration that keeps pulling all the way up to a top speed of 285 km/h. Indulgence without remorse: in spite of its stellar performance, the new BMW ALPINA B3 Bi-Turbo achieves excellent fuel economy in relation to its competitors. One of the B3 Bi-Turbo’s features that literally stands out are the four exhaust tips, with their catalytic converters contributing significantly to the achieving of low Euro4 emissions standards.
The intense driving experience and an immediate bonding with the B3 Bi-Turbo are markedly influenced by fine materials and superior ergonomics. The standard leather interior features comfortably-padded sport seats with excellent lateral support, making long journeys a joy. The ALPINA SWITCH-TRONIC steering wheel falls perfectly to hand and affords a clear view of the typical ALPINA blue instruments with their red pointers. As demanded by any enthusiastic driver, the provision of essential information in the form of the analogue oil temperature gauge located below the rev counter means the B3 Bi-Turbo can be pushed to its limits, once the minimum oil temperature of 50° C has been reached. Next to the analogue speedometer, the B3 Bi-Turbo also provides a digital speed read-out as well as average fuel economy and instantaneous fuel economy figures – thrifty driving also creates driving pleasure.
