Mercedes-AMG GT 63 S Coupe 4-door test: super sports car in evening dress


Mercedes brochures do not have to be yellowed any more: V8 6.2 of the sublime SLS, V12 6.9 of the fearsome CLK GTR, V12 6.0 Biturbos of the last S 65 AMG, none reaches the 639 hp of the V8 4.0 biturbo of our Mercedes AMG GT Coupe-4-door-63-S-4Matic + (to our liking). This means the escalation of power among the premium brands, which at least corresponds to the explosion of the number of bodies: three models at Mercedes in 1996, twenty-six in 2018.

"The Mercedes range? Three models in 1996, twenty-six in 2018!"

However, the new 4-door GT (short) is not necessarily an extended Mercedes-AMG GT. More like a close cousin of the Mercedes CLS, started six months earlier: same dashboard, same flag, same window without frame, same hull here with aluminum elements. And a difference in wheelbase (and in gauge), only due to the shock absorbers tested by the anchors. The ultimate development concerns the task of the trunk in favor of a tailgate … which could have justified a name "five doors" and not "four".

The Mercedes-AMG GT 4-door coupe is not limited to the evoked V8, but also reduces the performance: V6 435 hp for the GT 53or V6 367 hp for the GT 43… which also exists in the CLS area under the name 450 (Read our essay). More than a cousin, a twin!

For fans of anecdotes, we add that the French market has not retained the GT 63 version without "S" (driven by the V8 biturbo "deflated" to 585 hp) and that the GT 43 and 53 have the system lightweight hybrid -EQ boost: A small electric motor with 22 hp and 250 Nm supports the V6 at low speeds, increases flexibility and reduces fuel consumption. Insufficient to escape the maxi malus, which is stated in all versions of GT 4 to 10 500 €. But talked enough about bad topics …

The Mercedes-AMG GT 63 S cuts 4 doors from the front

For this first test of the Mercedes-AMG GT 4-door coupe we try to tame its advanced version 63 S, which is not only more powerful than the GT 43 and the GT 53. The front discs have a diameter of 360 to 390 mm and are therefore very well mounted on a bowl. The piloted suspension houses three-chamber air springs. The rear wheels are steeredturn the opposite from below 100 km / h (1.3 ° maxi) and in the same direction to (0.5 ° maxi).

The nine-speed automatic transmission swaps its converter through a wet clutch, while at the rear axle an active differential is introduced. In 4Matic + all-wheel drive, the drift mode with the E 63 S (Read our article again), which converts this integral of 900 Nm into simple drive. An explosive cocktail to test on the shining streets of Morocco … Like Josiane Balasko in a tanned ski (my film culture is endless): I go, but I'm scared.
