Mercedes-Benz Introduces AMG 4.0-Liter V-8 Twin-Turbo Engine
As if we didn't need another reason to enjoy the Mercedes-Benz AMG lineup, the brand has presented an all-new 4.0-liter V-8 twin-turbo engine that promises power and fuel efficiency. Its lightweight construction helps it achieve over 500 horsepower with a max torque of 479 lb.-ft. The new engine follows a tradition that started back in the late 1960s with the introduction of the M100 engine that was first seen under the hood of the 300 SEL 6.8 AMG. Christian Enderle, engine and powertrain chief at Mercedes-AMG said, "The new AMG 4.0-liter V-8 biturbo sees us presenting an exciting and powerful sports car engine which, thanks to a number of measures, also represents the next step in efficiency." However, the way the new V-8 has been put together is a first for a sports car engine. The two turbochargers aren’t mounted to the outside cylinder banks, but in the actual V configuration. Dubbed the "hot V," this offers a more compact engine design, which even lowers exhaust emissions. Thanks to dry sump lubrication, the center of gravity for the engine is closer to the road and delivers higher lateral acceleration. The M178, the in-house name for the brand new engine, has a dry weight of 460 lbs., making it the lightest engine in the segment. Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH, added to a recent press release that "V-8 engines are an integral part of the AMG philosophy and the brand's commitment to 'Driving Performance'. The V-8 biturbo engine for our new GT is going to delight our customers!" Source: Mercedes-Benz
