Why the V8 engine is not dead: Introducing the powerful AMG GT engine [video]

The technology that went into the new 2015 Mercedes AMG GT 4.0-liter V8 Biturbo engine was learned and earned through Mercedes-AMG involvement in motorsports at the highest level. This technology was transfered from Formula 1 and the DTM to customer sport activities in the SLS AMG GT3. This knowledge was transferred and optimized for daily use in production vehicles like the 2014 CLA-Class, 2015 GLA-Class and now the 2015 AMG GT performance car.

Powerful and efficient

The new AMG GT V8 is closely related to the AMG 2.0-liter turbo engine in the A 45 AMG, CLA 45 AMG and GLA 45 AMG, which is currently the most powerful, series-production four-cylinder engine in the world. Both AMG engines have the same bore/stroke ratio, ensuring their high revving ability. They also both use a third-generation direct gas injection with piezo injectors. The highly efficient and economical AMG 4.0-liter, V8 biturbo meets the Euro 6 emissions standard and the maximum particulate emissions level that takes effect in 2016.

Innovative technology

This engines stability is derived from the rigid crankcase and lightweight forged pistons. To help reduce friction losses, the cylinder walls are lined with an innovative nanoslide coating. It features a dry sump lubrication technology the front mid-engine does not not require a conventional oil pan and moves the engine center of gravity closer to the road. This creates a significant improvement for driving dynamics and high lateral acceleration.

To keep the unit as compact as possible, the engines two turbochargers are located inside the hot inner V8 engine block. An exceptional engine response is created due to the precise routing of fresh air into the exhaust turbo chargers. The result provides a thrilling driving experience in the new AMG GT.
