Spanish supercar maker Tramontana has released renderings and details of its new V12-powered XTR.
The XTR is Tramontana's second wildly-overpowered car, the first being the R and the open-top track car on which it was based.
Tramontana says the V12 is good for 653kW, and it's expected to better the R's 0-100km/h time of 3.7 seconds and 346km/h top speed.
The motivation behind those figures is Mercedes-Benz' familiar 5.5 litre bi-turbo V8, pushing the XTR's output up from the 536kW delivered in the R.
The XTR is based on the R, so the layout is still tandem two-seater, mostly carbon fibre, and hugely expensive. Expect it to stay under 1300kg.
Additions for the XTR include a new racing-spec transmission to replace the R's six-speed sequential and some aero parts to help keep the car on the ground.
As for its styling, the newer car looks less like a Dodge Prowler with bits stuck on and more like the Caparo T12 with a bit of Le Mans racer and Apache attack helicopter thrown in.
The R is built in extremely limited numbers - just twelve are made each year, although the company says it is searching for a bigger factory to increase production capacity.
The XTR is to be priced from €420,000, and, as the owner can specify whatever they like, the price on most cars will head boldy north. We'll let you know as soon as they build one.
