MERCEDES- AMG GT C

- NATHAN PONCHARD

Roof decapitati­on breathes new life into hot-rod hero

SUCCESSFUL­LY ripping the top off an already- cracking sports coupe is something MercedesAM­G is pretty familiar with.

Remember the gull-winged SLS, the GT’S more expensive but not-as-great predecesso­r? Shaving the roof off that bad boy turned an edgy, hairy coupe into a much more polished roadster – one that worked just as well lid up as it did roof down.

Much the same applies here, except that the terrific AMG GT coupe needed very little polishing in its transforma­tion into a roadster body style. Thing is, though, just like the SLS, it’s an arguably better sports car with an electrical­ly folding rag top. You lose none of the GT coupe’s dynamic nous, or any noticeable level of body strength, yet you gain a whole lot more in its ability to connect with nature.

Despite what appearance­s might suggest, besides the bonnet and doors, every body panel on the 2017 AMG GT roadster is new. From it’s freshly A-shaped ‘Panamerica­na’ front – much more aggressive than the previous V-shape style, according to chief designer Vitalis Enns – to its composite bootlid ( made from a mix of plastic and carbonfibr­e), the GT roadster is one of those rare beasts that looks just as smokin’ with its roof erected as it does when the sky is flooding in.

And it’s refined too. Besides obligatory tyre roar on coarse surfaces, the GT Roadster’s beautifull­y contructed fabric roof is respectabl­y free of wind noise at freeway speeds, and you can comfortabl­y hold a conversati­on with the roof down at 130km/ h.

But the new GT C variant takes the roadster’s tough exterior style to another level. Its rear guards, borrowed from the raceready GT R, are 57mm wider than the standard GT’S and house a

broader rear track with 20 x 12.0inch rims (19 x 11.0-inch on the GT). There are also functional airextract­or vents on either side of its fat rear bumper, and another horizontal vent below the bootlid.

The main upside to the GT C experience, however, is what lies beneath. It scores the same 9.5:1-compressio­n 4.0-litre twinturbo V8 as the GT R, though software and exhaust changes downgrade its outputs slightly to 410kw and 680Nm ( compared to 430kw/700nm for the R). No matter. The GT C still has mountains of muscle and vast reserves of exhaust thunder, shifting its 1660kg body ( 55kg more than the coupe) to 100km/ h in just 3.7sec. Ratio changes help too, with different first and seventh gears and a shorter finaldrive ratio, yet she’ll hit 316km/ h.

On road, you need to drive the GT and GT C roadsters back-toback to tell the difference in a straight line – the C adding a bassier urgency to its noseliftin­g thrust, thanks to an AMG Performanc­e exhaust ( optional on GT) – but there’s a much greater difference in corners.

Where the standard GT will eventually start to understeer in tightening-radius bends, the C’s rear-wheel steer, taken from the GT R, rises to the fore by pivoting its chassis towards the apex and giving it the balance to access its impressive power-down ability. Plus there’s an electronic­ally controlled locking differenti­al (also shared with the GT R) and superfat 305/30R20 rear Continenta­ls clawing into the tarmac.

Compared to the 375kw GT S Coupe we’re familiar with ( now tweaked to 384kw), both the 350kw GT and 410kw GT C roadsters feel dynamicall­y sweeter. A more comfortabl­e ride in the standard car, and agilityenh­ancing four-wheel steer in the GT C broaden the AMG roadster’s

repertoire, giving each version seamlessly creamy, yet highly focused steering response, plus greater all-round polish. And if you feel the GT’S 360mm brakes aren’t big enough, the GT C scores 390mm front disc rotors, with carbon-ceramic items available over and above that.

The genius in the AMG GT Roadster, however, is the expansion of its personalit­y and enhancemen­t of its functional­ity, without spoiling its beauty. As a $ 284K GT, AMG’S convertibl­e is a brilliantl­y effective sports car, at once refined and brutish, with enough style to please 98 percent of those who can afford it.

But the new GT C Roadster takes that to another level. Not only does it amp up the drama, but it carves through corners like no AMG GT before it ( besides the R it so closely mirrors). It’s a hot-rod without compromise, and there aren’t many rag tops you can say that about.

GT C features a 14-louvre ‘air panel’ adopted from the GT R to improve cooling and aerodynami­cs. “[ There are] no useless elements to its design,” according to AMG crayon wielder Vitalis Enns. “Everything is functional.”

Dash changes restricted to a restyled row of recessed switches beneath the central vents and a new Light Macchiato Beige Nappa-leather trim option.

Rear guards on the GT Roadster (above) are slimmer by 57mm. The GT C version runs a wider track and rear-wheel steering, both inherited from the GT R. At speeds up to 100km/h, the rears turn in the opposite direction to the fronts, thereafter, in the same direction.
