2026 Mercedes-Benz GLC
GLC is Mercedes' volume midsize crossover against X3 and Q5. Trade-offs: premium fuel, option packages that move price quickly, and mpg below hybrid luxury rivals.
What's confirmed (EPA 2026)
From Mercedes-Benz 2026 EPA listings:
- GLC300: 27 mpg combined (24 city / 32 highway)
- GLC300 4MATIC: 26 mpg combined (23/31)
- GLC300 4MATIC coupe: about 26 mpg combined (23 city; confirm highway on EPA row)
Practical notes
4MATIC costs a little mpg for AWD. Coupe variants are style-first packaging, not efficiency plays. Cross-shop X3, Q5, and RX 350h if mpg matters.
Safety (IIHS)
IIHS 2026 GLC page: ratings apply across 2023–26 (some tests 2024–26). Headlights Good; pedestrian front crash prevention Acceptable on standard systems (Good on some optional configs).
