first reported on the Danish firm's work back in May, but now we can put a bit more flesh on the bones of the car.
Originally there were whispers that HBH would be creating their own bespoke chassis, but it seems that the final product will actually be based on a (heavily, we presume) modified version of the 'normal' Aston V12 Vantage.
That might sound like a mammoth job for a company you've never heard of, but in fact HBH has supercar form, having designed the ST1 supercar for fellow Danes, Zenvo.
the New Stratos project.
Power of the new car will come from a twin-supercharged version of the Aston Martin V12, with 666bhp and 548lb ft of torque from the 6.0-litre engine. 0-60mph, they reckon, will be dealt with in 3.9secs, with a top speed of 186mph.
Clothing the modified under-bits is (or rather, will be) a body of hand-beaten aluminium.
Classic Driver. "In fact, in many ways it would have been easier and the weight of the body could have been slightly lower. But it just didn't feel right, given the heritage of Aston Martin. Instead, we chose to manufacture the body panels in hand-beaten aluminium - following Aston tradition."
HBH reckons on development for the new car taking 12 months to develop, so we could see it in the metal in early 2013.
