The fast four-door car from Affalterbach has been on the record lap on the Nürburgring-Nordschleife since last year. This was primarily made possible by the comprehensively revised chassis geometry with completely changed elastokinematics. New subframe bearings, adapted head bearings, stiffened tension struts and push struts ensure more precision on the rear axle. On the front axle, reaching for the bag of tricks was even bigger. Asymmetrical tension strut bearings have been used here since last year, which are flexible depending on the direction of load. For example, they are significantly more flexible in the longitudinal direction and therefore more comfortable, but do not allow any feedback or steering precision to be lost in the transverse direction.
The effort and fine-tuning in the context of series production is now being repeated for the six-cylinder models GT 43 4Matic + and GT 53 4Matic + (combined fuel consumption: 10.0-9.2 l / 100 km; combined CO2 emissions: 226-209 g / km²) because the two entry-level four-door models benefit from a completely revised damping system that comes straight from motorsport.
The new damper system of the Mercedes-AMG GT 4-door Coupé ensures more comfort
The heart of the newly tuned AMG Ride Control + chassis with multi-chamber air suspension are the continuously variable dampers for use with external pressure relief valves. This so-called piggyback solution is used separately in the Mercedes-AMG GT 4-door Coupé with the fine in-line six-cylinder, even for rebound and compression.
Both the compression and rebound of the bike can now be controlled separately and the damping can be perfectly adapted to the needs of the driver and the driving situation. In addition, the solution with the external control valves offers developers the option of realizing an even greater spread of the damping force characteristics. This means that both the GT 43 and the GT 53 are not only more comfortable, but also sportier when required. Because even if most of the big four-door vehicles from Affalterbach are moved more comfortably: They could if they had to.
The lifestyle changes only affect the GT 43 and GT 53 models.
Technically everything remains the same with both six-cylinder engines. With 270 kW / 367 PS and 500 Nm, as well as 320 kW / 435 PS and 520 Nm, however, even as the basic models they provide sufficient propulsion. In addition, the 48V e-booster with 22 hp and 250 Nm helps a lot at the start. Other changes relate purely to cosmetics. The most obvious change is that the six- and eight-cylinder models are now optionally the same. With the V8 styling package, all Mercedes-AMG GT 4-door Coupé now have the Panamericana radiator grille on the front, regardless of which engine is running under the bonnet.
For the market launch of the lifestyle update, Mercedes-AMG has also put together an edition model that stages all the changes. It stands in rubellirot-metallic on 21-inch forged wheels with aero applications. The exterior details shine in high-gloss chrome and inside the new AMG performance steering wheel in two-tone gray and black vies for attention. The wood of the edition model is gray ash, and there is also a matching exclusive leather interior in nappa neva gray.
Mercedes-AMG has not yet commented on the prices for both the edition and the other six-cylinder models. (Text: fm | Pictures: Manufacturer)
