This 1990 Alpina B10 BiTurbo is #53 of 507 E34s converted by the company and is powered by a twin-turbocharged 3.4L inline-six paired with a five-speed manual transmission. Finished in Diamantschwarz Metallic over gray upholstery, the car is equipped with 17″ alloy wheels, sport seats with patterned inserts, automatic climate control, a Blaupunkt stereo, and power windows, mirrors, and locks.
The car is finished in Diamantschwarz Metallic, and the seller states that the bumpers and hood have been resprayed. A Zender rear apron has been added along with AC Schnitzer side skirts, and additional exterior details include tinted windows, a power sunroof, Shadowline trim, an Alpina front spoiler, and Alpina, B10, and BiTurbo badging.
Silver 17″ Alpina wheels are mounted with 235/45 front and 255/40 rear Continental ExtremeContact tires showing 2019 date codes. A matching spare wheel and Michelin tire are mounted under the trunk floor. The B10 features Automatic Stability Control, and Alpina suspension changes include revised springs, anti-roll bars, and Bilstein front shocks with an automatic load-leveling system out back. Braking is handled 13″ ventilated rotors at all four corners.
The cabin features front power-adjustable sport seats and a rear bench trimmed in Alpina gray fabric with green and blue striped inserts. Features include burl wood trim, an Alcantara headliner, central locking, power windows and mirrors, an onboard computer, dual-zone automatic climate control, a Blaupunkt stereo, and an adjustable boost controller. A center console-mounted plaque indicates this chassis is the 53rd B10 BiTurbo built.
The four-spoke airbag steering wheel frames an Alpina-branded instrument cluster featuring a 320-km/h speedometer, a tachometer with an inset fuel economy readout, and gauges for fuel level and coolant temperature. The digital odometer shows 84k kilometers (~52k miles).
The 3.4-liter inline-six was modified by Alpina with twin Garrett T25 turbochargers, an intercooler, lightweight Mahle pistons, and a revised cylinder head and camshaft. Output was rated at 355 horsepower and 348 lb-ft of torque when new. A Zender strut-brace has been installed, and service in January 2021 involved replacement of the exhaust manifold gaskets, spark plug wires, ignition coil, engine mounts, and power steering fluid. Work performed in September 2021 included an oil change, coolant flush, and replacement of the thermostat, temperature sending unit, and oil pressure switch.
Power is delivered to the rear wheels through a five-speed manual transmission.
Manufacturer’s literature, service and import records, and two sets of keys are included in the sale.
