Mazda to race diesel P2 prototype in 2014 TUDOR United SportsCar Championship

8th January 2014 | BY Adam

It’s confirmed that this year Mazda will be competing in the TUDOR United SportsCar Championship in their prototype P2 diesel racer.
Their latest venture in to competitive racing with diesel engines come off the back of their success in the Rolex Grand-Am Championship last season. They won 9 out of twelve races in the Skyactiv Mazda 6, scooping the overall manufacturers title and proving that diesel engines absolutely have a place in motorsport.

The new P2 prototype is based around the Lola LMP2 chassis and features the same 4-cylinder, twin-turbo Skyactiv diesel engine found in their Grand-Am racer. With 50% of the stock internals still in tact, only the pistons, rods and crankshaft have been changed to cope with the increased horsepower in the race engine, reported to be 450bhp and 580lbft torque. Weighing in at just 900kg before fuel and driver are added, that gives the P2 a power to weight ratio of 500bhp/tonne.

Mazda took two cars testing at ‘Roar before the 24′, the annual pre-season publicity event where fans can watch the teams testing and get a closer look around the pits. Unfortunately the P2′s both suffered issues with broken driveshafts and when replaced with stronger ones, the transmission took the brunt and also failed. Although according to a Mazda team insider, it’s not a worry for the team as the lessons learned at this level are crucial for their success further down the line - most notably at Le Mans, which is what they have their sights set on.

We’ve said it before and we’ll say it again, Mazda are really impressing us with their dedication to pushing the limits and expectations of diesel powered race cars and we’re very much looking forward to how things progress over 2014….stay tuned.
