Volkswagen Audi Group AMB Engine

The Volkswagen Audi Group AMB engine was an inline four-cylinder turbocharged engine of the 1.8 T line, built from 2001 to 2003 by the Volkswagen Group in Ingolstadt, Germany, as the replacement for the earlier 1.8T engines such as the AEB. It differed from the AEB chiefly in its thinner 19 mm wrist pins in place of 20 mm ones. Each cylinder had five valves, three for intake and two for exhaust, a BorgWarner K03 turbocharger, multi-port electronic fuel injection and a cast iron block, and the design was built to handle more power than it was tuned for. It was mounted longitudinally in most Audi applications and transversely in most other cars, and was fitted to Volkswagens, Audis and cars of Group-owned makers such as SEAT, with five- or six-speed manual, five-speed automatic and, for front-wheel drive, CVT gearboxes. In 2003 slightly more powerful versions such as the AUM replaced it.
