2023 Aston Martin DBX707 Performance

The 2023 Aston Martin DBX707 is fitted with a twin-turbocharged 4.0-liter V8 that produces 697 horsepower and 663 lb-ft of torque. Power is sent to all four wheels via a nine-speed transmission. Mash the accelerator pedal, and the DBX707 will dispatch 60 mph in a claimed 3.1 seconds. Keep your left foot planted, and 0 to 100 mph quickly arrives in 7.4 seconds. The top speed is pegged at 193 mph.

The Bentayga Speed may have a larger engine, but it is outclassed in terms of power, acceleration, and top speed. The 631-hp Cayenne Turbo GT may not have as much hp, but its taut chassis and spirited dynamics more than make up for the deficit.

Sadly, the US-spec DBX707 is not rated for towing.

The 4.0-liter V8, sourced from AMG and tuned in-house, is the only engine available in the Aston Martin DBX707. The all-alloy quad overhead cam mill produces 697 hp at 6,000 rpm and 663 lb-ft at 2,750 - 4,500 rpm which makes for remarkable performance.

Motivation arrives at all four corners thanks to a nine-speed automatic transmission. The magnesium-bodied gearbox boasts a multi-plate wet clutch with oil cooling. As you'd expect, there are steering wheel-mounted shift paddles for manual control.

Drive it normally, and the V8 will emit nothing more than a polite grumble. Drive it like Aston Martin wants you to, and the mighty eight-cylinder awakens with a mighty bellow and propels the car forward with gusto. It's a masterpiece of an engine and works well with the gearbox.

DBX707 gas mileage figures show the Aston Martin to be more frugal than its rivals with estimates of 15/20/17 mpg city/highway/combined.

It's not exactly sparing when it comes to gas consumption, but it does better than the Bentayga Speed (14 mpg combined) and the Cayenne Turbo GT (16 mpg combined). The DBX has a fuel capacity of 22.5 gallons, allowing the thirsty SUV to travel up to 382.5 miles between refueling.

Interestingly, the regular DBX has poorer fuel economy, according to the EPA. It scores just 16 mpg on the combined cycle.
