- COMAND/MBUX software glitches (mostly fixed via updates)
Pros
- Sharp handling from rear-wheel drive
- Big boot & roomy rear seat
- Strong, efficient B-series engines
- 550 L boot growing to ~1,600 L — roomy for a mid-size SUV
- Efficient OM654 2.0 diesel (GLC 220 d: 194 hp / 400 Nm)
- MRA rear-wheel-drive platform with optional 4MATIC
- GLC 350 e PHEV: 320 hp system output and 560 Nm, company-car friendly
Cons
- Firm ride on M Sport (run-flat)
- Pricier than most rivals

Driving experience
BMW X3
Poised, accurate and remarkably car-like for an SUV. Steering is quick, well-weighted and precise, body control taut, and the X3 corners with the composure of a lower, lighter car. xDrive brings tenacious all-weather grip and a neutral, rear-biased balance, while the rare sDrive is lighter and more playful. Adaptive suspension keeps it composed on rough roads, if a touch firm on big wheels. The B48/B58 petrols are smooth and eager, the B47/B57 diesels pull strongly and stay hushed, and the xDrive30e plug-in glides on electric power. The ZF 8-speed is quick, seamless and always in the right gear. Overall a polished, driver-focused SUV that shrinks around you on a good road.
Mercedes-Benz GLC
Comfortable, quiet and more car-like than its height suggests. The GLC steers accurately with light, consistent weighting, rides well on the standard suspension, and stays hushed at motorway speeds. 4MATIC is standard on most versions and adds sure-footed traction without altering the relaxed character. The M274/M264 petrols are smooth and willing, the OM654 diesel is the economical distance choice, and the 300 e plug-in covers short trips on electric power. The 9G-Tronic shifts unobtrusively. It is a well-rounded, easy-to-live-with compact SUV that does everything competently.
