Aston Martin DBX: generations, engines and what to know when buying
The Aston Martin DBX is the British manufacturer's first luxury SUV, launched in 2020. We look at the DBX, DBX707 and DBX S generations, engines and what to consider when hunting for a used example.
DBX in brief
The DBX is a five-door luxury SUV that marks Aston Martin's first foray into this segment. The car is built in Wales on a bespoke aluminium platform with all-wheel drive and pneumatic suspension.
It's a rare and expensive car, so there aren't many used examples around. Buyers typically praise the distinctive design, interior trim and sporty driving character, which isn't typical of many rivals in this class.
Which version to choose
The base version is simply the DBX with a 4.0-litre V8 twin-turbo engine sourced from Mercedes-AMG. It offers more than enough performance and is the cheapest of the lot.
The DBX707 (from 2022) gets a more powerful engine, beefier brakes and sharper handling. It's the hotter version for those prioritising speed.
The DBX S (from 2024) is even more powerful, so there will be fewer of these on the market. If budget isn't an issue, most buyers will get more bang for their buck with the DBX or DBX707.
Engines and gearboxes
The original DBX engine is a 4.0-litre V8 biturbo, initially producing around 540 hp, later slightly increased. The DBX707 produces around 707 hp, while the DBX S churns out around 717 hp.
All versions come with a 9-speed automatic gearbox with wet clutch and permanent all-wheel drive. Manual gearboxes are not available.
What to check when buying a used DBX
The car isn't old, so the most important thing is a full service history with the official dealer and completed software update campaigns. Ask if there were any recall notices and check if they were all carried out.
Test the air suspension at all height settings and all electronic systems: the multimedia screen, cameras, sensors. Check the condition of the brake discs and tyres – a heavy, powerful car will wear them out quickly.
Luxurious leather interiors are prone to scratches, so inspect the sides of the seats and the steering wheel. Due to the high price, it's worth getting an independent inspection by a specialist.
