Hannover, Germany (Sep 23, 2014) – On the Cummins' stand (E18 Hall 11) at this year's IAA Show, visitors saw the Cummins Railton car; created by engineer Terry Clarke, it is a dimensionally accurate replica of the famous Napier Railton Special racing car.   

The original car was first raced in August 1933 by John Cobb, and broke the Brooklands outer circuit lap record of 143.44mph in 1935.  It set the 24 hour record of 150.6mph at the Bonneville Salt Flats in 1936.  Now based in the Brooklands Museum (Surrey, UK), the car is powered by Napier Lion XI gasoline aero engine, with 12 cylinders in three banks of four arranged in a ‘W’ configuration.  It has a displacement of 24 litres with a rated power of 530 hp at 2,350 rpm. 

Steve Nendick, Cummins Communications Director said; “We saw the project as an excellent opportunity to promote diesel power in areas you would not normally associate it with.  It enables us to highlight the key product developments that have made our modern diesel into an efficient and ultra clean form of power.  Technologies such as advanced combustion with high pressure fuel systems and the latest turbocharging will allow us deliver the equivalent power of the original iconic car with a significantly smaller engine.”

The replica is powered by Cummins’ ISBe, an in-line 6 cylinder, 6.7 litre engine.  Designed and built in the UK, it is normally available up to 310 hp for commercial applications with tough duty cycles such as double deck city buses, rigid trucks and military vehicles.  To push the engine power capability, a number of high specification components have been added including the block, cylinder head, camshaft, pistons, fuel injectors and turbocharger.

“Using the latest components, coupled with engine development and electronic controls expertise, Cummins’ engineers have achieved close to 500 hp.  Working with Terry Clarke, they have recommended some minor configuration changes that will increase the power further.  Although this is not destined for full production, it highlights the capabilities of our diesel engines and engineers to push the envelope in challenging projects,” added Nendick.   

Cummins has a strong history in racing, using it to test product durability as far back as the 1930s.  In fact, the 1931 No. 8 Duesenberg Indianapolis 500 car, built around the same time as the Railton, was also driven at Brooklands during a European tour organised by the company founder Clessie Cummins.  This car still runs and is displayed in the Indianapolis Motor Speedway Museum.
