The Aston Martin DBX borrows three major components from Mercedes-Benz: the 4.0-liter twin-turbo V8 engine, the nine-speed automatic transmission, and the 4Matic AWD system. The platform is all Aston, however. This means that the DBX doesn't feel too Germanic, as Aston made sure to mix enough of its DNA into the design.
The engine produces 542 hp and 516 lb-ft of torque. Aston Martin claims a 0-60 mph time of 4.5 seconds and a top speed of 181 mph. So it's fast but not as quick as most of its rivals.
The interior is gorgeous. Aston Martin uses high-quality materials, which goes a long way towards justifying the high asking price. Unfortunately, Aston also uses a defunct Mercedes infotainment system, which is intensely annoying once you've driven any modern car with a touchscreen interface.
The driver-assistance suite consists of adaptive cruise control, a speed limiter, forward collision warning with autonomous braking, lane departure warning with lane keep assist, rear cross-traffic alert, blind-spot monitoring, door opening warning, and traffic sign recognition.
