2026 Mercedes-Benz GLC vs. Lexus RX: Specs

Both the GLC and Lexus RX are available with a turbocharged four-cylinder as their base engine, and both lineups offer a plug-in hybrid option. With that said, the GLC lineup includes two dedicated Mercedes-AMG® performance trims, neither of which has a true rival in the Lexus RX lineup. Power-related Mercedes-Benz GLC vs. Lexus RX specs range from 255 hp on the base GLC 300 SUV up to a massive 671 hp on the Mercedes-AMG® GLC 63 S E PERFORMANCE SUV. In comparison, the Lexus RX lineup spans 275 hp on the base RX 350 up to 366 hp (net combined output*) on the Lexus RX 500h F SPORT Performance.

That gives the top-tier GLC over 300 additional horsepower and roughly 2.4 fewer seconds to 60 mph than the fastest Lexus RX configuration. Standard models also feature available 4MATIC® all-wheel drive for enhanced control during Western Massachusetts winters. Overall, Mercedes-Benz offers a wider spectrum of performance—efficient commuting in Longmeadow, plug-in hybrid efficiency, and bold, racing-inspired Mercedes-AMG® power—giving you more options for tailoring your next SUV to your exact driving needs.
