ALPINA have been creating exclusive automobiles based on the BMW 3 Series. In the beginning of this continuing success story spanning over 6,000 units was the legendary 1978 BMW ALPINA B6 2.8 – revolutionary in its day due to its six cylinder engine. This success story is continued in a most prominent fashion by the BMW ALPINA B3 Bi-Turbo.
The straight-six cylinder petrol powerplant manages to accommodate torque and power in a compact, nimble and efficient package like no other car in its segment.
400Nm (294lb-ft) of torque from 1300rpm onwards, peaking between 3800rpm and 5000rpm at 500Nm (368lb-ft), provide plenty of punch and elasticity, rocket-like launching the B3 Bi-Turbo from standstill if required, or sovereignly navigating traffic at the touch of your foot.
The omnipresence of Its sporty character means the engine revs freely, accompanied by a wonderful soundtrack, to a maximum 7000rpm, offering up 360hp (265kW) along the way between 5500rpm – 6000rpm.
The use of extremely durable MAHLE pistons allows for a maximum boost of 1.1 bar with 9.4:1 compression. The result, a peak specific output of 121hp (89kW) per litre and a maximum average pressure of 21 bar.
An ideal 50:50 front/rear axle weight distribution in combination with a carefully chosen blend of suspension components make for a great overall chassis set-up, which is equally engaging and comfortable. Stiffer rear axle suspension mounts, for example, increase steering precision and feedback, especially noticeable during fast lane changes.
Low profile conventional tyres which forego Run Flat technology in favour of comfort in combination with light weight alloy 18″ or 19″ ALPINA wheels ensure that unsprung mass is kept to a minimum.
