Video: Mercedes-AMG confirms the GT’s new stonking 4.0L twin-turbo V8

Mercedes-Benz released a teaser video evolving around the highly-anticipated Porsche 911-fighting AMG GT. The video focuses more so on the AMG GT’s stonking 4.0L twin-turbocharged V8 good for more than 500hp and 479 lb-ft of twist.

The engine’s internally coded as the M178 and has a relatively impressive dry weight of just 460lbs. This is accomplished with a lightweight construction like pistons, overhead camshafts, and flow-optimized cylinder heads made with a unique zirconium alloy. Additionally, dry-sump lubrication is used so there’s no need for a conventional oil pan. Additionally, the engine features a nano-slide coating, assisting in reducing friction losses.

This same engine will not only see duty in the AMG GT, but in the next generation C63 AMG as well.
