Alpina D3 Bi-Turbo Coupe with N47D engine

The original Alpina D3 was based on the BMW 320d sedan and made its debut at the end of 2006. The 2.0 litre inline-4 single turbo diesel engine received an upgraded turbo, resulting in an increase from 170hp to 200hp, and 410Nm (up from 340Nm) of torque between 2,000-3,000rpm. It sold 850 units since its introduction.

This year a new Alpina D3 debuts called the Alpina D3 Bi-Turbo Coupe based on the E92 Coupe. Like the D3 Sedan, it is also powered by a 2.0 litre turbodiesel engine but this time it is the new twin turbocharged BMW N47D from the BMW 123d. The N47D’s stock power levels of 204hp and 400Nm have been upgraded to 214hp and 450Nm.

The brakes have also been uprated from the ones in the D3 from 300mm front and rear to 330mm and 336mm from and rear respectively. The engine radiator has also been uprated in size for better cooling. The 6-speed manual version is upgraded from the ZF SG6-37 to the ZF SG6-53 to handle the higher torque. This new gearbox can handle up to 520Nm of torque. The automatic model which Alpina calls Switch-Tronic is loosely based on ZF’s 6HP19TU but adds an extra planetary plate and a different flywheel for 100ms upshifts. Driveshafts, propshaft and halfshafts have been uprated for the higher torque.

Aesthetics that help it be identified as an Alpina include a front lip, Alpina floor mats, a straight exhaust system with no rear box that allows a 5,200rpm redline (high for a diesel engine), sport suspension, Alpina alloy wheels, and the typical Alpina instrument cluster with a blue background.

    technically, its not from bmw, but from alpina. Alpina buys the cars from bmw, rebuilds them, and resells them with a new alpina chassis number, and the cars are also registered as an alpina. but alpina has such an interesting relationship with bmw, that the cars are still warranteed by bmw. Alpina cosmetic parts are also sold only to alpina owners.

    I would rather have the M3 or any Bimmer unadultered. Still like the black and blue with BMW lettering on the hood.
