The 2026 Mercedes-Benz GLC is a high-tech, luxurious, and spacious compact luxury SUV that’s a bestseller for all those reasons and more.

Driving Impressions

The non-AMG models in the 2026 GLC SUV lineup don’t put speed and acceleration at the forefront of the driving experience. Still, they’re quick, nonetheless, with the base GLC 300 capable of 5.9-second zero-to-60-mph runs, the 4Matic all-wheel-drive GLC 300 good for 6.0 seconds, and the GLC 350e plug-in hybrid electric vehicle (PHEV) doing the deed in 6.3 seconds.
You might notice that the GLC 350e is the slowest of the group, despite also being the most powerful. Both of those traits are due to the presence of the PHEV system, which, although it boosts total output, also weighs enough to counteract that extra power, at least if acceleration from a stop.
Fuel Economy
The GLC 350e’s extra PHEV bits also mean it’s slightly less efficient after you’ve depleted the battery, earning a 25 mpg combined EPA rating versus the mild hybrid GLC 300’s 26 mpg combined. Both variants are on par for the compact luxury SUV segment, most earning between 25 and 29 mpg combined.
That said, the GLC 350e is rated at 64 MPGe when you take its impressive all-electric range of up to 54 miles into account.
