New Aston Martin Vanquish Volante arrives – costs £200k

The New Aston Martin Vanquish Volante (pictured) costs £200k It’s almost exactly a year since the Aston Martin Vanquish arrived as a replacement for the DBS, and now we get it’s convertible sibling – the new Aston Martin Vanquish Volante. Aston are claiming the new Vanquish Volante is the stiffest Aston convertible ever and have also managed to keep the usual weight increase for a soft top down to just 9kg by giving the Volante a full carbon fibre body. The result of that is the Volante manages to produce exactly the same performance figures as the Vanquish Coupe – 0-62mph in 4.1 seconds and 183mph – from its 565php, 6.0 litre V12 and shouldn’t, we hope, shake and shimmy in the way many Aston convertibles do in the process.
