One of these days we’ll do a tank-engined car showdown, and this Rover SD1 will be among the contenders. We could go on for a while, but PPC’s intro sums it up nicely:

One day back in the 1990s a middle-aged man from a sleepy village in Lincolnshire decided that he’d start a new project saloon car. Over a decade and two marriages later PPC’s own Charlie Broomfield had a road legal matt black Rover SD1 powered by a 27-litre V12 Merlin tank engine.

It seems his goal is to take it up to 200mph. So there ya go. You need to head over to PPC, because they’re basically a UK version of Hooniverse. Seriously, check out their project cars page. Rover SD1 27L V12 at Practical Performance Car via Save The Enzos
