History of Alpina B9

The first generation of BMW 5-Series M was the E28 model, which came out in 1981. Alpina B9, on the other hand, delivers a somewhat lower level of performance but a far higher level of elegance and style. Based on the BMW 528i, the B9 has a 3.45L engine instead of the M30-2.8L BMW engine. Engine modified by Alpina. Built on the M30 3.5L motor, the engine has been significantly reworked. All the engine parts were changed by Alpina, including the cylinder head, pistons, camshaft, and ECU. Alpina B8 offered a 5-speed gearbox and an automatic transmission to transmit the engine's performance. Although the E28's suspension has been upgraded to include Bilstein gas dampers, the B9's 16-inch wheels came standard with the vehicle. A new shifter and instrument panel were also added by Alpina, in addition to Recaro seats.


Online car auctions sites offer and provide different prices for the Alpina B9. The starting price for a used 1983 Alpina B9 is $30,000 for the most basic option and features and a staggering $70,000 for a top-of-the-line model.


Bilstein suspension components, five-speed Getrag manual transmissions, and 16-inch wheels take the B9's hair-raising performance to the ground. The use of an automatic transmission was entirely up to the customer. With its custom upholstery, Recaro seats, special gauges, redesigned gear knob, and leather-wrapped steering wheel, the B9's interior got a dose of premium luxury. The B9's red badging accentuates the exterior's aggressive rear spoiler and front splitter.


The 1984 Alpina B9 engine delivers 241 hp (180 kW) at 5,700 rpm and 236 lb-ft (320 Nm) at 4,500 rpm of torque. The Alpina B9 accelerates from 0 to 60 mph (97 kph) in 7.3 seconds with a top speed of 140 mph (225 kph) and a curb weight of 2,998 lbs (1,360 kg). Alpina offered the Alpina B9 as a rear-wheel-drive (RWD) model with a 5-speed automatic transmission powered by a 3.5L inline V6 engine.
