the excort cosworth has been ford's group a rally car for the last 3 years.
2 litre turbo (inline) (essentially the old sierra cosworth running gear).
it is a full works rally car with 34mm restrictor to limit to about 300hp.
the 'world rally car' is an fia idea to replace the old group 'a' rules which
replaced (sigh) the old group 'b' cars (aka quattro s1, pug t16 evo 2,
lancia delta s4/2). group 'a' required 2,500 similar examples. the world
rally car requires 25,000 but gives a much freer hand with modifications
with only 20 cars needing to be produced. the cars look much better and
more like the old group 'b' cars.
it also frees up manufacturers from having to produce awd cars in order
to go rallying because awd hardware can be sourced from ourside of the
manufactures product stable and bolted onto the chosen car.
if you follow rallying you will know that, despite having 'only' 300hp, the
group 'a' cars have been significantly faster over special stages than the
group 'b' cars of the mid 1980's, due mainly to better suspensions and
diffs. recent advances in 'active' diff technology continues to push the
