It's a Ford RS200.. Yes it does have a Cosworth engine.
200 were built for Rallying under the old Group B rules in 1986. Unfortunately after some bad accidents, due primarily to lack of crowd control the category was banned in 1987.
Of the 200, 6 were destroyed as part of the development program ( it under went full crash and emissions testing) and a further 20 were dismantled to use for parts.
The fastest 0 to 60 time ever recorded in one was 2.6 secs. This was done in 1986 by Stiq Blomquist testing for the UK magazine Autocar. O to 100mph is done is 6.93 and depending on the gearing installed the 1/4 in 10.9 or less.
I take delivery of it around the end of January. The current owner enjoys outperforming big bikes and even F40's and Xj220's. He says the look on the owners faces is priceless.
This car actually appears in the video Too Fast to Race which details all of the Group B cars.. Oh and also shows the most gorgeous woman ever to step into a rally car, Michele Mouton. She very nearly won the World Rally championship in 1986, mastered the awesome 650hp Audis, held the pikes peak record for 14 years and is still the only woman to have won a world championship motorsports event.
Never mind the cars, she's worth buying the video for
