Settling into the driver's seat reveals an interior that, like the exterior, offers the unique world of Aston Martin. Supple semi-aniline leather covers the seats and instrument panel, complemented by genuine carbon fiber trim on the center console. This space, a masterful fusion of "sportiness" and "luxury," mirrors the coupe models, including the DB series, truly embodying Aston Martin's signature excellence.

The space surrounding the driver feels appropriately snug, and apart from a slightly elevated seating position, the posture is that of a sports car. These elements further reinforce the sense that the DBX 707 inherits Aston Martin's DNA.

The design of the five circular buttons arranged in the center of the instrument panel is also consistent with recent Aston Martin models. Pressing the starter button located in the center awakens the 4-liter V8 twin-turbo, its deep, powerful beat resonating within the cabin.

Like the DBX V8, this engine is based on a Mercedes-AMG unit. It employs more responsive ball-bearing turbochargers and has undergone dedicated tuning, resulting in 707 horsepower and 900 Nm of torque—a significant increase of 157 hp and 200 Nm over the base DBX V8. Despite its substantial weight of 2,245 kg, it achieves 0-100 km/h in 3.3 seconds and a top speed of 310 km/h, performance befitting the Aston Martin name.

To handle the increased power, the 9-speed automatic transmission has been changed from a conventional torque converter to a wet multi-plate clutch system developed for racing cars. The propeller shaft has also been upgraded to a more robust carbon fiber construction.

To enhance stopping power, the vehicle is equipped with carbon-ceramic disc brakes, known for their lightweight design and stable braking performance across a wide temperature range. This braking system also contributes to a reduction of 40.5 kg in unsprung weight.

Furthermore, comprehensive enhancements have been made to various driving-related elements, including optimized tuning of the air suspension system and electronic active roll control system, the adoption of a new version of the electronic limited-slip rear differential, and improved feel from the electric power steering.
