A brand new Riley & Scott with the best technology

In 2001, the Riley & Scott MKIII C succeeded the MKIII which had been launched in 1995 and was the main competitor to the Ferrari 333 SP. The idea behind this new model was not to evolve the MKIII but rather to create a completely new car using, of course, the experience gained from designing the Cadillac Northstar LMP for General Motors in 2000.

The chassis is made of steel with carbon inserts and is much stiffer than that of the MKIII: At the launch of the MKIIIC, Bob Riley indicated that it was 40% stiffer than the MKIII. Externally, there are major changes. In accordance with LMP900 regulations, the roll bar no longer runs the full width of the cockpit, but is only present behind the driver. It is taken directly from the Northstar LMP. The front of the cockpit has also been redesigned, with an aerodynamic windscreen added immediately in front of the driver.

The front end is also more rounded and plunging. The radiator inlets are designed to cover the full width of the nose, but are slimmer. The airflow is much better managed, the aerodynamics are optimised and the MKIIIC benefits from much more downforce at high speed.

Mechanically, the MKIII C's transmission is a marked improvement over the MKIII. A market benchmark, the X-Trac 6-speed sequential gearbox is present. It is controlled by a pneumatic system developed by Megaline and activated by paddle shifts on the steering wheel. The motorization is entrusted to Elan which equips the very efficient Panoz and then YATES in 2003. The brakes are now in carbon. 

 
The MKIIIC has been studied and validated by Audi engineers 

Proof of the seriousness of the MKIII C project, Audi had spied on the American manufacturer. Indeed, a chassis had been obtained by the brand with rings, which studied it in its own wind tunnel. By studying it in great detail, the Ingolstadt engineers saw that the Americans had done a good job. A competitor with potential, so much so that Audi was more than a little curious. 

 
Riley & Scott MKIIIC on the podium at the 24 Hours of Daytona and the 12 Hours of Sebring 

The results were not long in coming, in 2002 the #04 chassis entered by Riley & Scott finished 2nd in the 24 Hours of Daytona and 3rd in the 12 Hours of Sebring. During the 24 Hours of Le Mans, it qualified in 16th position while running on Good Year tyres, which was not at all a guarantee of speed as we will see the following year...

In total, five MKIII Cs were assembled. Only four were entered in competition, chassis #03 being the one used for the FIA crash test.

Riley & Scott MKIII C #005: the ultimate Riley & Scott MK3C

Chassis #005 offered for sale and part of the Ascott Collection is the last chassis assembled by Riley & Scott and entered as an official car by Riley & Scott in 2003. In 2003, Jim Matthews, who was already racing the official car of 2002 (chassis #04), is still the pillar of the official Riley & Scott team. The car will enter the American Le Mans Series (ALMS), and the 24 Hours of Le Mans. It was also entered in the one-off 1000km Le Mans event in September 2003, the start of the Le Mans Series. Its last competitive outing was at the 2004 12 Hours of Sebring. A short career of one year.

This Riley & Scott MKIIIC was particularly noticeable at the 2003 24 Hours of Le Mans. The team had changed tyre supplier and the official Riley & Scott was now equipped with Michelin tyres.

In the big week of the 24 Hours of Le Mans Marc Goossens set an exceptional time of 3'37''476. The car was 7th on the grid, behind the Bentley Speed 8, the Audi R8 and a Dome S101. By comparison, the fastest Audi R8 (the #10 of Biela, Salo and McCarthy) is in 3'35''745. The Riley & Scott is less than two seconds behind the best Audi R8, a performance that does not go unnoticed as the Riley & Scott MKIII C is on the pace of the best LMP900s of the moment. Unfortunately, the engine broke during the race, forcing the team to retire. In 2004, it was entered in the LMP1 class at the Sebring 12 Hour race, where it qualified in 8th place.

The winning car in the Endurance Racing Legends LMP1B Championship in 2022 - 3rd place in 2023 an 2024

This Riley & Scott MKIIIC has proven that it's a car built to win since it started competing in historic races. Xavier Micheron has driven it to numerous podium finishes. Whether in the support race for the 2021 Le Mans 24 Hours, in the Masters Endurance Legends or in the Endurance Racing Legends, this car has always been among the front runners. At the end of the 2022 season, it won the Endurance Racing Legends Championship in its class and overall. In 2023 and in 2024, third place in the Championship was achieved. A solid performance given the high level of competition!

 

Excellent value for money

This Riley & Scott MKIIIC from the 2003 Le Mans 24 Hours is undoubtedly the LMP900 that offers the best value for money, thanks in particular to its engine, which is packed with torque and power and can run 5000 km between overhauls.

The engine was overhauled prior to the Dubai GP Revival race in December 2023, where Riley & Scott achieved another podium finish.

Both easy to maintain and extremely well engineered, it benefits from excellent preparation by the Scott Sport team and Lap Engineering (Lee Penn).

 

The highest level of specification for a car of this era

A stiff chassis coupled with effective aerodynamic loading, a 620bhp engine controlled by traction control, a sequential XTRAC gearbox with paddles, electric power steering, tyre pressure sensors, a latest-generation Motec and dashboard, and carbon brakes.

This Riley & Scott is ready to conquer new podiums in 2025.
