Over 200 people are killed each year when backed over by motor vehicles. The Envision has standard Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision.

An engine control system that can shut down some of the engine’s cylinders helps improve the Envision’s fuel efficiency. The GLB doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Buick Envision uses regular unleaded gasoline (mid-grade octane recommended for maximum performance). The GLB requires premium, which can cost on average about 35.1 cents more per gallon.

The Envision 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 GLB doesn’t offer a cap-less fueling system.

A nine-speed automatic is standard on the Buick Envision, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the GLB.

The Envision’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the GLB are solid, not vented.

For better traction, the Envision Sport Touring/Avenir’s tires are larger than the largest tires available on the GLB (245/45R20 vs. 235/55R18).

The Envision has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the GLB; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the GLB don’t have a run-flat feature, either.

The front grille of the Envision uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The GLB doesn’t offer active grille shutters.

The Envision’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 GLB does not have an oil pressure gauge.

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