2016 Mercedes-AMG GT 4.0-Liter V8 Biturbo Engine Information
To get you up to speed on the 4.0-Liter V8 Biturbo Engine on the all new Mercedes-AMG GT, here's some of what you need to know about it, from a Mercedes Press Release:
The newly developed AMG 4.0-liter V8 biturbo engine
The new high-performance engine springs to life at the push of a button. The
4.0-liter V8 biturbo engine was developed specifically for the GT. The
innovative eight-cylinder engine boasts outstanding power delivery,
performance figures on a par with motor racing, lightweight construction as
well as high efficiency and environmental compatibility. It boasts the brand's
hallmark emotive V8 engine sound, along with an immediate response and
high pulling power.
The new AMG V8 engine (internal designation M178) stands out with its
precise power output, which is easily a match for a naturally aspirated engine. The linear power delivery makes it easy to handle the vehicle even at its limits.As part of this process, the sophisticated ECU even factors in the current driving condition and adjusts the accelerator response depending on the lateral forces generated.
With a displacement of 3982 cc, the V8 uses a range of technologies which are already being used in the 2.0-liter turbo engine in the CLA45 AMG -- presently the most powerful, series-production four-cylinder engine in the world. Both engines have the same bore/stroke ratio, providing the basis for high revving ability. The piezo direct petrol injection used at Mercedes-Benz is responsible for the mixture formation. The spray-guided combustion process was further developed in the third generation to meet all future legal requirements.
First sports car engine with 'hot inside V' and dry sump lubrication
The new AMG V8 engine has two turbochargers which are not mounted on the outside of the cylinder banks but rather inside the V configuration – experts call it a "hot inside V". The benefits are a compact engine design, an optimum response from the turbochargers and low exhaust gas emissions thanks to optimum air flow for the close-coupled catalytic converters. The dry sump lubrication also ensures the oil supply even with high lateral forces and allows the engine to be installed lower, thus moving the center of gravity closer to the road and forming the basis for high lateral acceleration. The new Mercedes-AMG V8 biturbo engine is the world's first sports car engine with 'hot inside V' and dry sump lubrication.
A tradition of hand-built excellence: "one man, one engine"
The 4.0-liter V8 biturbo engine is being made in Affalterbach according to the "one man, one engine" principle. In the AMG engine shop, highly qualified master engine builders assemble the engines by hand according to the strictest quality standards. Once completed, this impeccable standard is clearly visible on the AMG engine plate, as it bears the engine builder's actual signature. "One man, one engine" ties in with Mercedes-AMG's unique motorsport genes, which exude innovative strength by virtue of the technology transfer from the racing series – from Formula 1, the DTM to the involvement in customer racing with the SLS AMG GT3.
