We've just driven the Mercedes GLE 450 AMG Coupe from Stuttgart, in Germany, to Kitzbuhel, in Austria, and right at this moment, it is parked outside a tony restaurant where we are lunching on fresh river fish.The Coupe is facing me, and I can't help but think that it looks like one of DonThe Godfather Corleone's thuggish enforcers. With that forward-sloping bonnet, upright grille and short overhang, it is a face that you wouldn't want to see in your rear-view mirror (unless you're driving a BMW X6). And, that's probably one reason why a lot of cars gave way as I gunned it on the autobahn leading from Germany to Austria.The second reason is that the Coupe is primed for pace. A lot of things happen when you thumb the starter button and floor the pedal. The twin turbos start shovelling air into the engine; in Sport, the suspension tautens; and downshifts from the slick nine-speed transmission are acoustically enhanced. Each time you aim for a corner, you realise two things\: this Coupe can handle, and that the transmission, which is combined with a 4Matic permanent all-wheel drive system, keeps the engine in just the right rpm window. Meanwhile, it's calm inside the cabin. Music pipes out of a Bang \& Olufsen system; there are tasteful flashes of carbon fibre and you simply watch the world turn into a Hyperlapse video from your AMG sports seat. Mercedes calls the 450 AMG Coupe an entry into the world of AMG, and so, yes, this 362bhp V6-engined beast is not a true-blue AMG. The real beast that we'd love to get our hands on, whenever the opportunity presents itself, is the GLE 63 S Coupe, whose hand-built engine spews some 577 horses. The GLE range, which includes regular non-AMG tweaked and enhanced models, should be out in India by the middle of next year, but coming up in November is the fastback's bigger, more sedate, non-coupe brother, the GLE. The GLE, of course, is the M-Class, which was Mercedes-Benz India's highest-selling SUV, and a global hero for Mercedes. And, the latest iteration looks set to consolidate Mercedes' position as one of the world's top luxury SUV makers.The new GLE looks sharper and sprightlier than the M-Class, and certainly more elegant. I wonder whether it has spent the last couple of years browsing through men's style journals. There are familiar ML design elements all around, but the real deal is the cabin that shares lots of bits with the Coupe. Folks who can afford to spend over Rs 50 lakh will be treated to interior trim in various types of wood, a COMAND controller with a touchpad and large, snug seats.On the road, our GLE 250D pleasantly reminded us of the M-Class. The 2.0-litre, 204bhp engine, also found in the outgoing model, pulled cleanly and strongly; the new nine-speed transmission works efficiently in the background, and switching between driving modes even produced pleasing growls from the hard-working diesel motor. The SUV will also be available with a V6 (both units have been tweaked for better fuel efficiency and lesser emissions), and there will also be a hybrid model. And a 577bhp GLE63S, of course. As is to be expected of a Merc SUV, the all-wheel drive GLE offers a supple ride, and will come with a suite of features, and we expect it, especially the more practical diesel model, to do the job of mopping up sales figures for Mercedes even as its Coupe brother steals the spotlight.
