Mercedes-Benz GLC 300 Long Term Review – 4 Months Mumbai Test, Grace & Glitches

The Mercedes-Benz GLC 300 proves itself as Mumbai’s ultimate luxury daily driver after 4 months of real-world testing, blending silky 2.0L turbo-petrol mild-hybrid power (258 hp, 400 Nm) with class-leading ride comfort. However, MBUX glitchesdust-magnet paint, and 7-9 kmpl city mileage remind it’s not flawless.​

Price: ₹75.20 lakh (ex-showroom). Perfect for luxury seekers who crave refinement over perfection. Compare rivals in our GLC vs XC60 guide.​


Driving Experience: Silky Smooth, City Crawl Challenges

The GLC 300’s 9-speed auto delivers Mercedes polish on highways like Sea Link, where adaptive suspension glides effortlessly. Mumbai potholes? The air suspension irons them out like a built-in chiropractor.

Real-world mileage:

  • City (Mumbai traffic): 8-9 kmpl (drops to <7 kmpl with AC blast)

  • Highway: 12-14 kmpl

Low-speed gearbox hesitation in stop-go traffic feels un-Mercedes-like – built for cruising, not crawling.​​
