The Fiat 131 built by Rally Sport Developments is expected to make an eagerly-anticipated debut on round four of the West Wales Rally Spares R.A.C. Rally Championship, the Severn Valley Stages (31 May).An entry has been placed for former British Historic Rally champion Julian Reynolds and co-driver Ian Oakey and, subject to a shakedown test in the run up to the rally, the car will start the rally from Builth Wells on Saturday morning.The Fiat, which replicates the late 1970s works cars, is the result of more than two years of graft by Kevin Theaker at RSD in Malton and was first unveiled to widespread acclaim at Autosport International in January. Theaker’s outstanding engineering ability has been used to faithfully recreate the best-loved rallying Fiat and includes re-manufacturing many key components, including engine block, cylinder head and suspension.Reynolds says it is an honour to be invited to drive the car, on what will be his first rally for 18 months, but says it will be a journey into the unknown. “What Kevin has done is amazing,” said Reynolds. “It’s a fantastic project. I actually looked at buying a 131 a few years ago, so to now get the chance to drive one is amazing.”Reynolds has so far only seen photographs of the car and says that he is keeping expectations in check for the Severn Valley. “I’m keeping a very open mind on it,” he said. “It is so new and Kevin has built it from nothing, so I have no big expectations at this stage. But I have no doubt that it will be competitive in due course.“I have a passion for Escorts but it will be nice to see something out there challenging them, just like Owen Murphy is doing with the Sunbeam Lotus. I can’t wait to see what the Fiat is like!”Reynolds’ last rally was the 2012 Roger Albert Clark Rally, which only lasted around four miles, so he will also be playing himself back in to competitive driving.
