The 2027 Mercedes-Benz GLS450 has undergone a significant refresh, focusing on powertrain enhancements and exterior design updates. This entry-level luxury SUV now boasts a more powerful and refined engine, delivering impressive acceleration. However, its ride quality leans towards a softer, more comfort-oriented feel, which some might find a bit 'wallowy'. The aesthetic updates are quite noticeable, particularly the increased integration of the brand's iconic three-pointed star logo across the vehicle's exterior.

This revised model features a potent 3.0-liter turbocharged inline-six engine, augmented by a redesigned electric supercharger, resulting in a substantial output of 375 horsepower and 413 pound-feet of torque. This robust powertrain enables the GLS450 to achieve a 0-60 mph sprint in a brisk 5.1 seconds. Despite the engine's smooth and capable performance, the vehicle's suspension tuning prioritizes a plush ride, which, while comfortable for cruising, can sometimes lead to a less controlled, undulating driving experience. Visually, the updated exterior proudly showcases an abundance of Mercedes-Benz's signature star emblem, reinforcing its brand identity.

Enhanced Performance and Engine Refinements

The 2027 Mercedes-Benz GLS450 introduces a thoroughly revised powertrain, centered around a 3.0-liter turbocharged inline-six engine. This unit is complemented by an advanced electric supercharger and other internal modifications designed to boost both power and efficiency. The result is a substantial output of 375 horsepower and 413 pound-feet of torque, enabling the luxury SUV to achieve a commendable acceleration of 0 to 60 mph in just 5.1 seconds. This combination of power and quickness ensures a dynamic driving experience, particularly for an entry-level model in its segment, while maintaining the characteristic smoothness expected from a Mercedes-Benz.

At the heart of the 2027 GLS450's performance upgrades is its sophisticated 3.0-liter turbocharged inline-six power plant. Mercedes-Benz engineers have meticulously refined this engine, integrating an updated electric supercharger alongside other critical enhancements. These improvements collectively contribute to a significant increase in power, now rated at 375 horsepower, and a robust 413 pound-feet of torque. This formidable output translates into a remarkably swift 0-60 mph acceleration time of only 5.1 seconds, positioning the GLS450 as a strong contender in the luxury SUV market for those who prioritize brisk performance. The engineering focus was not solely on raw power, but also on delivering a seamless and responsive power delivery, ensuring that the driving experience remains refined and exhilarating.

Exterior Styling and Ride Dynamics

The exterior of the 2027 Mercedes-Benz GLS450 has been refreshed, featuring a design that prominently incorporates a multitude of the brand's iconic three-pointed stars. While this updated aesthetic enhances the vehicle's luxury appeal and brand recognition, the ride dynamics present a notable characteristic: a somewhat "wallowy" sensation. Despite the smooth operation of its powerful engine, the suspension tuning prioritizes a soft, comfortable ride, which might lead to a less composed feel over certain road surfaces, particularly for drivers accustomed to a firmer, sportier setup.

The updated exterior of the 2027 GLS450 showcases a bold design direction, most notably through the extensive use of Mercedes-Benz's distinctive three-pointed star emblem across various parts of the vehicle. This design choice aims to reinforce brand identity and exude an aura of luxury. However, when it comes to the driving experience, the GLS450's ride is often described as feeling somewhat "wallowy." This characteristic stems from a suspension system that is tuned for maximum comfort, absorbing road imperfections with a soft, compliant response. While this provides a serene and cushioned journey for passengers, particularly on longer trips, it can result in a more pronounced body roll and a less direct feel when navigating turns or uneven terrain, contrasting with the engine's otherwise smooth and powerful performance.
