2027 Mercedes AMG GLE 63 S Gets a Surprising V8 Upgrade

Mercedes AMG is proving once again that the V8 engine still has a place in the performance sport utility vehicle world. The newly revealed 2027 Mercedes AMG GLE 63 S arrives with one of the biggest mechanical updates in the model’s history, combining traditional V8 power with modern hybrid technology while delivering even more performance than before.

At a time when many manufacturers are downsizing engines and moving toward electrification, Mercedes AMG has chosen a different path. The company has taken its legendary 4.0 liter twin turbocharged V8 and given it a major redesign. The new M177 Evo engine now features a flat plane crankshaft, a significant departure from the previous cross plane design used in earlier AMG models.

The result is an impressive 603 horsepower and 627 pound feet of torque. An integrated 48 volt mild hybrid system adds another layer of performance, contributing up to 23 horsepower and 151 pound feet of torque when needed. Together, these upgrades help the high performance luxury sport utility vehicle sprint from 0 to 60 miles per hour in just 3.6 seconds.

For enthusiasts, the flat plane crankshaft is one of the most exciting changes. This design is commonly found in exotic sports cars because it allows the engine to rev more freely and respond more quickly to throttle inputs. Drivers can expect sharper acceleration, improved responsiveness, and a more emotional driving experience behind the wheel.

The performance improvements extend beyond the engine. Mercedes AMG has retained its advanced AMG Performance 4MATIC+ all wheel drive system, ensuring that all available power is delivered efficiently to the pavement. The vehicle also continues to use AMG Ride Control+ air suspension, adaptive dampers, active roll stabilization, and an electronically controlled rear differential. Together, these systems help balance comfort and performance while maintaining impressive handling for a vehicle of this size.

Visually, the 2027 GLE 63 S receives several updates that give it a more aggressive appearance. The front fascia has been revised with a new AMG specific grille design, updated lighting elements, and fresh wheel options. Quad exhaust outlets remain a signature AMG feature, instantly reminding everyone that this is not an ordinary luxury sport utility vehicle.

Inside, Mercedes introduces the latest generation of its digital technology. The cabin features updated MBUX infotainment software, support for over the air updates, and access to the company’s newest operating system. Drivers and passengers will also benefit from the available Superscreen dashboard layout, creating a more modern and connected experience.

Despite all the new technology, the biggest story remains the engine. Many enthusiasts feared that future AMG performance vehicles would lose their V8 identity. Instead, Mercedes AMG has invested heavily in keeping the V8 alive while adapting it to meet modern efficiency and emissions requirements.

The 2027 Mercedes AMG GLE 63 S demonstrates that performance and electrification do not have to be opposites. By combining a powerful twin turbocharged V8 with hybrid assistance, Mercedes has created a luxury sport utility vehicle that remains true to its performance heritage while embracing the future.

Deliveries are expected to begin in Fall 2026, and pricing will be announced closer to launch. However, one thing is already clear. The new GLE 63 S is shaping up to be one of the most exciting high performance luxury sport utility vehicles on the market and could become one of the last great AMG V8 powered sport utility vehicles ever built.
