The GLS’ pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Bentayga doesn’t offer pre-crash pretensioners.

The GLS’ driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Bentayga doesn’t offer a driver alert monitor.

The GLS has standard Mercedes-Benz Emergency Call, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Bentayga doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the GLS and the Bentayga have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems, rearview cameras and available lane departure warning systems.

The GLS comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Bentayga’s 3-year basic warranty expires 1 year sooner.

The GLS’ corrosion warranty is 2 years longer than the Bentayga’s (5 vs. 3 years).

There are over 8 times as many Mercedes dealers as there are Bentley dealers, which makes it much easier should you ever need service under the GLS’ warranty.

The design of the Mercedes GLS amounts to more than styling. The GLS has an aerodynamic coefficient of drag of .32 Cd. That is lower than the Bentayga (.34) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the GLS get better fuel mileage.
