Mercedes has lifted the covers off the GLE 63 S AMG – the new performance range-topper of its recently unveiled GLE Coupe SUV – at the Detroit motor show this week.
The new model, which will snappily be called the Mercedes-AMG GLE 63 S-Model Coupe 4Matic, has been conceived as a direct rival to the BMW X6 M, which has enjoyed sales success in SUV loving markets such as China and Russia.
The new Mercedes outguns its BMW rival with its 5.5-litre turbocharged V8 engine, which produces 577bhp, compared to the X6 M's 564bhp. That power is sent to all four wheels through a seven speed automatic transmission, and is enough to get this large SUV from 0-62mph in a Porsche 911-beating 4.2 seconds, and on to a top speed of 155mph - or, optionally, 174mph if you specify the AMG Drivers' Package.
Amongst the go-faster upgrades over the standard GLE, which has also made its public debut at the Detroit show, the AMG model gets sports suspension with roll stabilisation, as well as revised electric power steering.
In typical AMG style the GLE 63 gets a smattering of blingy exterior details, including a new front bumper with gaping air vents, AMG's new twin-plane grille and four exhaust tailpipes.
