The Envista 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 Coupe doesn’t offer a cap-less fueling system.

The Envista 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 Coupe doesn’t offer vehicle monitored tire inflation.

The Envista’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 Coupe does not have an oil pressure gauge.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Envista’s available exterior PIN entry system. The GLC Coupe doesn’t offer an exterior PIN entry system, and its Mercedes-Benz Emergency Call can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.
