2027 Mercedes-AMG GLE 63 S Keeps the V8 Alive

The 2027 Mercedes-AMG GLE 63 S 4MATIC+ proves that AMG is not ready to give up on the V8. At a time when many performance vehicles are moving toward smaller engines and heavier hybrid systems, AMG has chosen a different path. The latest GLE 63 S continues to deliver the kind of performance that enthusiasts expect, while introducing important engineering upgrades that make the vehicle even more responsive and engaging.

Under the hood sits an updated 4.0-liter twin-turbocharged V8 engine. While the displacement remains the same, AMG engineers have redesigned key components to improve efficiency, throttle response, and overall performance. The biggest change is the introduction of a flat-plane crankshaft. This technology is commonly found in exotic sports cars and allows the engine to rev more freely while delivering a sharper, more aggressive character.

The result is an impressive 603 horsepower and 627 pound-feet of torque. An integrated 48-volt mild hybrid system can temporarily contribute an additional 23 horsepower and 151 pound-feet of torque during acceleration. Together, the system gives the large luxury sport utility vehicle explosive performance whenever the driver requests it.

Power is sent to all four wheels through the AMG Speedshift 9-speed automatic transmission and the AMG Performance 4MATIC+ all-wheel-drive system. Launch control helps the GLE 63 S sprint from 0 to 60 miles per hour in just 3.6 seconds. That places this luxury family vehicle firmly in sports car territory.

One of the most interesting aspects of the new engine is how it delivers its power. The revised V8 feels more eager throughout the rev range and responds instantly to throttle inputs. Whether accelerating out of a corner or merging onto a highway, the engine provides effortless performance with a sense of urgency that makes every drive more enjoyable.

Of course, no AMG V8 discussion would be complete without mentioning the exhaust sound. The new flat-plane crankshaft changes the character of the engine’s soundtrack compared to previous AMG models. Instead of the traditional deep rumble associated with older AMG V8 engines, the new setup produces a sharper and more exotic sound.

At idle, the engine still delivers the muscular tone buyers expect from an AMG product. Under acceleration, however, the exhaust note transforms into a higher-pitched performance soundtrack that resembles some of the world’s most exciting supercars. Turbocharger whistles, crackles during downshifts, and aggressive bursts from the exhaust create a driving experience that feels special every time the vehicle is started.

Mercedes-AMG has also carefully tuned the exhaust system to preserve the emotional connection between driver and machine while meeting modern emissions requirements. The result is a vehicle that sounds exciting without becoming overwhelming during long highway journeys.

Beyond straight-line performance, the GLE 63 S benefits from AMG Ride Control+ air suspension, active roll stabilization, rear-wheel steering, and an electronically controlled rear differential. These technologies help disguise the vehicle’s size and weight, making it feel remarkably agile for a high-performance luxury sport utility vehicle.

The 2027 Mercedes-AMG GLE 63 S 4MATIC+ demonstrates that there is still a place for a handcrafted V8 in today’s automotive world. With over 600 horsepower, lightning-fast acceleration, advanced chassis technology, and an unforgettable exhaust note, it continues the AMG tradition of combining luxury and performance into one exciting package.
