The Bentayga has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged.

On the EPA test cycle the Bentayga running its gasoline engine gets better mileage than the Cayenne Coupe running its gasoline engine:

The Bentayga Hybrid can travel with zero emissions for 18 miles. The Cayenne Coupe can’t move without running its internal combustion engine.

An engine control system that can shut down some of the engine’s cylinders helps improve the Bentayga V8’s fuel efficiency. The Cayenne Coupe doesn’t offer a system that can shut down part of the engine.

The Bentayga Hybrid’s standard fuel tank has 1.3 gallons more fuel capacity than the Cayenne Coupe S E-Hybrid/Turbo E-Hybrid’s standard fuel tank (19.8 vs. 18.5 gallons), for longer range between fill-ups.

For better stopping power the Bentayga’s brake rotors are larger than those on the Cayenne Coupe:

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The Bentayga has standard Hydraulic Brake Assist to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Cayenne Coupe doesn’t offer a brake assist feature.

For better traction, the Bentayga has larger tires than the Cayenne Coupe (285/45R21 vs. 255/55R20).

For greater off-road capability the Bentayga has a 1.5 inches greater minimum ground clearance than the Cayenne E-Hybrid Coupe (9.7 vs. 8.2 inches), allowing the Bentayga to travel over rougher terrain without being stopped or damaged. The Bentayga’s minimum ground clearance is .2 inch higher than on the Cayenne Turbo E-Hybrid Coupe (9.7 vs. 9.5 inches).

The design of the Bentley Bentayga amounts to more than styling. The Bentayga has an aerodynamic coefficient of drag of .34 Cd. That is lower than the Cayenne Coupe (.34 to .35). A more efficient exterior helps keep the interior quieter and helps the Bentayga get better fuel mileage.

The Bentayga has a larger cargo volume with its rear seat folded than the Cayenne Coupe with its rear seat folded (62.6 vs. 53 cubic feet).

Pressing a button automatically lowers or raises the Bentayga’s rear seats, to make changing between cargo and passengers easier. The Cayenne Coupe doesn’t offer automatic folding seats.

The Bentayga has a much higher standard payload capacity than the Cayenne Coupe (1510 vs. 853 lbs.).

This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Cayenne Coupe doesn’t offer a remote starting system.

The Bentayga EWB’s optional power side swing out doors make it much easier to load and unload kids and cargo. One touch opens the door, before you even get to the sport utility. The Cayenne Coupe doesn’t offer a power rear door.

Optional air conditioned front and rear seats keep the Bentayga’s passengers comfortable and take the sting out of hot leather in summer. The Cayenne Coupe doesn’t offer air-conditioned seats in the rear.

The Bentayga has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the Cayenne Coupe.

Both the Bentayga and the Cayenne Coupe offer optional massaging front seats. The Bentayga also offers optional massaging rear seats in order to maximize comfort and eliminate fatigue on long trips. Massaging rear seats aren’t available in the Cayenne Coupe.
