The Cayenne Turbo S E-Hybrid Coupe can drive on battery power alone for up to 31 miles. The Q7 must run its internal combustion engine to move.

Regardless of its engine, regenerative brakes improve the Cayenne Coupe’s fuel efficiency by converting inertia back into energy instead of wasting it. Audi only offers a regenerative brake system on the Q7 55 TFSI.

The Cayenne Coupe’s standard fuel tank has 1.2 gallons more fuel capacity than the Q7 55 TFSI’s standard fuel tank (23.7 vs. 22.5 gallons).

The Cayenne Coupe’s optional launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Q7 doesn’t offer launch control.

The Cayenne Coupe offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The Q7 doesn’t offer ceramic brake rotors.

The Cayenne Coupe Turbo has standard air brakes, which adjust the spoiler automatically during high-speed braking in order to shorten stopping distances. The Q7 doesn’t offer air brakes.

Tires and Wheels

For better traction, the Cayenne Coupe has larger standard tires than the Q7 (F:275/45R20 & R:305/40R20 vs. 255/55R19).

The Cayenne Coupe’s standard 275/45R20 front and 305/40R20 rear tires provide better handling because they have a lower 45 series front and 40 series rear profile (height to width ratio) that provides a stiffer sidewall than the Q7’s standard 55 series tires. The Cayenne Coupe’s optional 315/30R22 rear tires have a lower 30 series profile than the Q7 Prestige’s optional 35 series tires.

For better ride, handling and brake cooling the Cayenne Coupe has standard 20-inch wheels. Smaller 19-inch wheels are standard on the Q7.

The Cayenne Coupe has a standard space-saver spare (not available on E-Hybrid) so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Q7; 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 Q7 don’t have a run-flat feature, either.

The Cayenne Coupe offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The Q7 doesn’t offer an active sway bar system.

The Cayenne Coupe offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Audi doesn’t offer an active suspension on the Q7.

The Cayenne Coupe has a standard automatic load leveling suspension to keep ride height level with a heavy load or when towing. The Q7 doesn’t offer a load leveling suspension.

For better maneuverability, the Cayenne Coupe’s turning circle is 1.2 feet tighter than the Q7’s (39.8 feet vs. 41 feet).

The Cayenne Coupe’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 Q7 does not have an oil pressure gauge.

To help drivers see further while navigating curves, the Cayenne Coupe offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Q7 doesn’t offer cornering lights.
