The Terrain has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The GLC doesn’t offer a cap-less fueling system.

The Terrain has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The GLC doesn’t offer vehicle monitored tire inflation.

For better maneuverability, the Terrain w/17” wheels’ turning circle is 1.3 feet tighter than the GLC’s (37.4 feet vs. 38.7 feet).

The Terrain’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The GLC does not have an oil pressure gauge.

To improve rear visibility by keeping the rear window clear, the Terrain has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the GLC only has an intermittent setting, so in a hard rain visibility isn’t as good.
