Back in 2009, we heard that Mercedes-Benz and AMG had plans to replace its entire engine lineup with a new range of more fuel efficient direct-injected and turbocharged powerplants. A few months later we had official details on one of the most anticipated of the newcomers, a 5.5-liter V-8 that is to replace the 6.2-liter unit found in the current AMG lineup.
It was codenamed M157 and had plans to offer serious power. The new 5.5-liter engine is set to feature direct-injection and twin-turbocharging technologies, this to ensure it produces more power and torque than the current 6.2-liter naturally aspirated mill. Peak output stands at 544 horsepower and 590 pound-feet of torque, however, an available Performance Pack sees output increased to 571 horsepower and 664 pound-feet of torque thanks to additional boost pressure from the turbos.
After news of the engines, spy photos began coming in. And this weekend, the next generation ML AMG SUV was spied again by Motor Authority. Though still heavily covered, we are able to now see the fabricated air intake pipes on the front bumper and air vents on the hood. Thanks to the latest photos, we also get a good look at the large disc brakes at the front and the new AMG wheels, also expected on the next-generation GL AMG SUV. A new bumper and quad exhaust exhaust can be found at the rear.
Almost certain to pick up the performance division’s new twin-turbocharged 5.5-liter V-8, the speedy SUV will be called the ML63 AMG and will likely be launched soon after the standard version later this year. The new V-8 engine produces more power and torque than AMG’s current 6.2-liter naturally aspirated mill, with output peaking at 544 horsepower and 590 pound-feet of torque. However, a likely available Performance Pack should see output increased to 571 horsepower and 664 pound-feet of torque thanks to additional boost pressure from the turbos.
Signs that this is most certainly the AMG variant are the oversized cross-drilled brakes and dual exhaust tailpipes. We can expect a slightly lowered ride height as well as a sports tuned suspension.
