The exterior styling of the Vanquish is an evolution of the DBS with many styling cues such as the elongated side strakes being inspired by the One-77. The boot lid included an integrated rear spoiler designed to look as if it is impossible to make, this was done on the orders of the then Aston Martin Chief Executive, Dr. Ulrich Bez. The car has an exposed carbon fibre side skirt showing its all carbon fibre body. The Vanquish uses the new VH Generation IV platform which is lighter and uses more carbon fibre components than the VH Generation II platform used in the DBS.
The car featured a new interior with details inspired by the one found in the exclusive One-77. The standard interior was upholstered in hand stitched leather and Alcantara and was available in a range of colours. The centre console has an revised infotainment system as opposed to the one found in the DBS. The car was available as either a 2-seater or 2+2.
The Vanquish used an upgraded version of Aston Martin's 5.9-litre AM11 V12 engine called the AM28 with a power output of 565 BHP at 6,750 rpm and torque of 620 N⋅m (457 lb⋅ft) at 5,500 rpm. The Vanquish can accelerate from 0 to 100 km/h (62 mph) in 4.1 seconds, and has a top speed of 295 km/h (183 mph). Like many modern Aston Martin automobiles, the engine is front-mounted with the transmission in the rear for better weight distribution. The Vanquish has 51/49 front/rear weight distribution, and a kerb weight of 1,739 kg (3,834 lb). It uses a fully catalysed stainless steel exhaust system with active bypass valves. The car uses an updated Touchtronic II six-speed automatic gearbox. It was the first Aston Martin model to be available with launch control. The combined space of cabin and a boot that, at 368 litres, is more than 60% larger than that of the DBS.
The braking system uses ventilated carbon ceramic discs, 398 mm (15.7 in) six-piston callipers in the front and 360 mm (14.2 in) four-piston calipers in the rear. The suspension is a lightweight aluminium front sub frame with hollow castings with independent double wishbones incorporating anti-dive geometry, coil springs, anti-roll bar, and monotube adaptive dampers in the front and independent double wishbones with anti-squat and anti-lift geometry, coil springs, anti-roll bar, and monotube adaptive dampers in the rear. It has a three-stage adjustable adaptive damping system including normal, sport and track modes. The tires are Pirelli P Zeros, 255/ZR20 in the front and 305/30 ZR20 in the rear.
The Vanquish was unveiled in the London Film Museum, Covent Garden, followed by the 2012 Monterey Car Week. Deliveries to UK and Continental Europe began in late 2012.
