Mercedes-AMG GT Coupe
Engine & Performance
The GT53 and GT63 employ the renowned twin-turbo 4.0-liter V-8 engine from Mercedes, coupled with an innovative nine-speed automatic transmission. Generating 469 horsepower and 516 pound-feet of torque, the Mercedes-AMG GT Coupe GT53 exemplifies power. While the GT63 impresses with a robust 577 horsepower and 590 pound-feet of torque. Mercedes has repositioned the engine slightly forward. Situating it atop the GT’s front axle line instead of its previous rear placement. This adjustment translates to augmented interior space, potentially compromising the front-to-rear weight distribution. The newly incorporated standard all-wheel-drive system promises enhanced acceleration from its predecessor and the capability to channel 100 percent of the engine’s torque to the rear axle. Enabling captivating burnouts and donuts.
Price & Mileage
Anticipate a notable contrast of around $40,000 in cost when juxtaposing the GT55 against the GT63. If you’re contemplating the fiscal chasm, direct your focus to the substantial surge of vigor. Boasting a spirited 577 horsepower and 590 pound-feet of torque. Additionally, an available package introduces carbon-ceramic brakes, surpassing the dimensions of standard wheels on a full-size Sprinter delivery van. The starting point for the GT coupe’s pricing is projected at $150,000. Of course, this abundance of horsepower inevitably demands fuel, although the EPA’s estimations remain pending. Drawing from the preceding AMG GT iteration, the former 577-hp AMG GT R Pro secured a 15 mpg city and 20 mpg highway rating. Considering the present model now encompasses all-wheel drive and likely carries extra weight, marginal improvements are envisaged at best.
Acceleration & Features
Mercedes asserts that the GT63 boasts a 0-60 mph acceleration of merely three seconds, with the integration of rear-wheel steering and an electronically-controlled limited-slip differential ensuring the GT’s agility. When it comes to negotiating challenging driveways or speed bumps, the AMG GT offers an optional nose-lift system that elevates the front by 1.2 inches. Across all AMG GT Coupe variants, you’ll find a standard 11.9-inch infotainment touchscreen, complemented by convenient wireless smartphone charging. Notably, both Apple CarPlay and Android Auto come as standard features, in addition to the high-quality Burmester audio system that enriches your driving experience.
Porsche 911 GT3 RS
Engine & Performance
The GT3 RS, making its debut this year. Receives a power boost to 518 horsepower from the same 4.0-liter flat-six engine. It boasts a range of aerodynamic enhancements that generate substantial downforce, ensuring exceptional road adhesion. Notably, the rear wing features a drag-reduction system akin to Formula 1 race cars. The latest generation of GT3 models introduces a notable performance upgrade with a control-arm front suspension. A first for a production 911. Combined with adaptive dampers and high-performance Michelin Pilot Sport Cup 2 or even stickier Cup R tires. The coupe’s chassis delivers a remarkable cornering grip and unparalleled sensory feedback.
Price & Mileage
Porsche offers two variations of the “standard” GT3, namely the winged model and the Touring variant which opts for a more subdued appearance by removing the prominent rear wing. Additionally, there is the ultimate GT3 RS, which stands out as the most hardcore option. It’s a tough decision to choose just one among these extraordinary cars. But our admiration leans towards the extraordinary GT3 RS. The Porsche 911 GT3 has a starting price of $171,150 for the GT3, reaching up to $225,250 for the GT3 RS. According to EPA ratings, the automatic transmission-equipped 911 GT3 achieves 15 mpg in the city and 18 mpg on the highway. Opting for the manual transmission lowers the city rating to 14 mpg.
Acceleration & Features
The engine used in the latest 911 Speedster, which revved up to 9000 rpm and emitted a captivating sound, is virtually identical to the one found in this model. On the track, the automatic transmission achieved an impressive 2.7-second 0-60 mph time. While the six-speed manual demonstrated its prowess with a quick 3.3-second acceleration to 60 mph. The GT3 version of the 911 inherits the infotainment system from the regular model. Featuring a 10.9-inch touchscreen positioned at the center of the dashboard, supplemented by convenient physical controls on the steering wheel and center console. Porsche’s connectivity features include wireless Apple CarPlay and a Wi-Fi hotspot, with the option to upgrade to a Bose stereo system.
