Review and road test of the Mercedes-AMG GT

HOT INSIDE

Mercedes and AMG bring us the sports car we knew they were capable of. Jonathan Crouch reports on the revised Mercedes-AMG GT.

Ten Second Review of the Mercedes-AMG GT

The Mercedes-AMG GT continues to shake up the high performance sportscar market with a combination of extreme power, sleek styling and all the combined know-how of the Affalterbach and Sindelfingen works. Recent improvements have made the Coupe and Roadster variants look a little classier and there's now quite a choice in terms of engine output.

Background

The first Mercedes was a racing car. Ever since, the brand has had competition in its bloodline, drawn upon throughout a rich history of motorsport-orientated coupes and roadsters. Cars like this one, the Mercedes-AMG GT. Mercedes-AMG is a brand that enthusiasts may now be used to, its primary focus being the creation of high performance versions of usually mundane Mercedes models. Every so often though, this Affalterbach division gets let off the leash to do its own thing and on the first occasion that happened, we got something very special - the SLS of 2009. As with the SLS, this GT model still uses a V8 beneath the bonnet, but its 4.0-litre engine is smaller and quicker-responding, with lighter weight and twin turbos comfortably compensating for the power deficit over its predecessor's 6.2-litre normally aspirated unit. The experience here though, isn't just about power: Mercedes set out with this GT to create the most involving driving machine ever to sit in its regular model line-up. Quite a claim. Quite a car? Let's find out.

Driving Experience

'Mercedes builds a 911', screamed all of the enthusiast mags, who then stopped screaming that when they saw this car. The AMG GT is quite a different thing, power being delivered by a 4.0-litre twin-turbo V8 driving the rear wheels. The powerplant has an unusual layout, with the turbochargers not attached to the outside of the engine like most ancillaries, but housed inside the 'V' of the V8 - something AMG calls the 'hot inside V' configuration. As for the models on offer, well the standard GT generates 523hp and 670Nm of torque and is offered in Coupe or open-topped Roadster guise with two trim options. 62mph from rest takes 3.8s en route to 194mph. If for some reason that's not fast enough, the Roadster body style is also available in a 557hp GT C guise. At the top of the range, there's the 585hp GT R coupe variant that was race-tuned on the Nurburgring Nordschleife. Across the range, drive goes to the rear via a seven-speed AMG DCT-SPEEDSHIFT dual clutch gearbox. Transmission toys include a 'RACE START' launch control feature and software that blips the throttle on downshifts to the evocative accompaniment of popping and banging from the switchable AMG Performance exhaust system. The exhaust note is one of the parameters influenced by the various settings of the car's 'AMG DYNAMIC SELECT' driving mode system, this being one of those set-ups that can alter throttle response, steering feel, gearshift timings and stability control thresholds to suit the way you want to drive. This rear transaxle system offers decent weight distribution, with 47 per cent of the car's weight up front and 53 per cent aft. Depending on the model, the transmission offers up to six different driving settings: 'Slippery', 'Comfort', 'Sport', 'Sport Plus', 'Race' and a configurable 'Individual' mode. All versions are fitted with a standard locking differential. The GT R variant also gets active driveline mounts which continuously isolate the mass effects of the engine and transaxle.

Design and Build

Buyers choose between Coupe and Roadster bodystyles, but either way, the styling of the AMG GT follows a definite theme, the long bonnet and squat glasshouse of the Coupe version being an evolution of the SLR and SLS models. It's a subtler and gentler shape than both though, but not without purpose, with squat haunches suggesting all its power is balled up at the driven wheels. From the rear, there are elements of Porsche 911 in its curves which may or may not be deliberate, but it's a car with nary a bad angle. It's just a shame that we have to do without the SLS's magnificent gullwing doors. Changes to this revised model include re-styled exhaust tailpipes, exterior styling enhancements, smarter LED High Performance headlamps and a new and front and rear view camera package, with parking sensors and parking assistant. Like the old SLS, the GT is built around a lightweight aluminium body structure that, in this case, weighs a mere 231 kilos. Drop inside and you're greeted with a broadly sweeping dash with a hugely chunky centre console. The sightlines at first seem a bit pinched but the driving position is lovely and Mercedes has fitted a beautifully tactile steering wheel. There's even an element of practicality too, Mercedes realising that cars in this class are built to be used rather than looked at. The rear hatch allows access to a luggage compartment with a capacity of some 350-litres.

Market and Model

For the Coupe model, expect to pay just over £108,000 for the GT version, around £117,000 for the 'GT Night Edition' variant and around £158,000 for the GT R. The asking figures put this Mercedes up against cars like the Aston Martin Vantage, the Porsche 911 GTS and the Audi R8. The open-topped Roadster bodystyle is offered with the base GT model's 530hp engine for around £120,000, or you can have the 'Night Edition' version of it for around £129,000. The 557hp GT C Roadster variant costs just under £154,000. Whichever variant you choose, you'll find that the interior's beautifully finished, with aluminium shift paddles, silver chrome trim elements and sports seats in ARTICO material. A free-standing 10.25-inch central display is located centrally above the four ventilation outlets. The driver operates the seat heating, PARKTRONIC, the hazard warning lights and, depending on the equipment, the extendable rear aerofoil using the buttons in the top control panel in the roof frame. The instrument cluster is served by a 12.3-inch screen. AMG GT buyers can further boost performance of their car through the fitment of optional carbon-ceramic brakes and Michelin Pilot Sport Cup 2 tyres.

Cost of Ownership

For a car with a turbocharged V8 engine, fuel economy isn't as catastrophic as you'd imagine. The GT with both bodystyles returns up to 22.2mpg on the combined cycle and up to 290g/km of CO2, while the GT C Roadster doesn't impose too much of a penalty for its additional 27hp, returning up to 22.1mpg and emitting up to 291g/km. The GT R Coupe manages 22.2mpg and 289g/km. All variants get better economy and lower emissions than something like an old Honda S2000. Residual values are likely to hold up well given that this is a rare product line. You'll need to book a service every 12,500 miles, which is more frequent than a Porsche 911's 20,000-mile stops, but this AMG comes with a three-year, unlimited mileage warranty and Mercedes' 30-year 'Roadside Assistance' breakdown cover. And it's worth knowing that your maintenance outlay can be kept a little in check by going for the optional 'Service Care' package.

Summary

The Mercedes-AMG GT is continuing to get all manner of rivals very worried indeed. It's got everything from a Nissan GT-R to a Bentley Continental GT in its gunsights and the AMG team at Affalterbach are extremely confident of success. Perhaps the most difficult thing is pinning down exactly what this car is. That might sound trite; it's clearly a two-seater supercar but this market is driven by nuance. Enthusiasts are clear about what differentiates, say, an Aston Martin Vantage from a Jaguar F-TYPE R. Where the AMG GT might struggle is in trying to be all things to all customers. If that's the extent of its problems, Mercedes will be delighted. The fact that this car isn't marketed as a Mercedes-Benz, instead carrying the 'Mercedes-AMG' badging, speaks volumes. This is a new-era Stuttgart sports car. And a very good one indeed.
