The rear-driven model will be launched next year, after the upcoming new V8 Vantage, with a higher performance focus than its grand tourer forebears. Although it is labelled as a DB11 S in the video below, Autocar understands it is a Vanquish mule.
Under the bonnet will be Aston Martin's turbocharged 5.2-litre V12 engine, but power will be ramped up so it will produce considerably more than the 600bhp offered by the V12 DB11. This will edge it towards the realm occupied by the Ferrari 812 Superfast, which has a 789bhp 6.5-litre V12.
The DB11 bodywork of the spotted mule gives no clues as to how the next Vanquish will look, but the fitment of a large rear spoiler, front lip and wheels that are larger than the DB11's 20in ones are all nods to the finished product's more aggressive set-up.
The Vanquish will use its own version of the DB11's structure, which will also underpin the next Vantage. Due to its harder focus, the Vanquish's underpinnings will be the most aggressive of the trio, as illustrated by the spotted development car, which clearly sits lower and corners with less bodyroll than the DB11.
Aston Martin often runs development versions of upcoming cars under the body of sibling models, with the most recent example being the V8 Vantage, which is due for launch later this year. It has recently been seen with production bodywork, but sightings earlier this year were of a 'cut and shut' DB11 mule.
The company's decision to shift the Vanquish into supercar territory is part of a line-up blitz, where Aston Martin will also launch a mid-engined rival to the Ferrari 488 GTB and McLaren 720S in 2021. Also planned is the DBX SUV in 2019, to be built at Aston Martin’s new factory in St Athan, Wales, and two Lagonda models: likely a saloon first in 2020, followed by an SUV in 2022.
The new models will sit beneath the brand's halo model, the Valkyrie hypercar.
