Track day drivers looking for the next step up in their motorsports careers got a look at the future on July 19th and 20th when Dyson Racing and RaceCo showed off the dramatic Caterham SP/300.R on the East Course at Miller Motorsports Park.

A project of England’s Caterham Cars, the SP/300.R was designed by Lola Cars with input from and development work by America’s legendary sports car championship-winning Dyson Racing. As part of the team’s role as the SP/300.R’s exclusive distributor for the Americas, Dyson Racing recently completed a nationwide tour, demonstrating this futuristic Le Mans Prototype-inspired sports-racing car to enthusiast drivers at premier motorsports facilities around the nation.

At Miller Motorsports Park it was two-time American Le Mans Series driver champion Chris Dyson who gave rides and coached prospective owners during their own laps behind the wheel of the Caterham SP/300.R.

“I really enjoyed the folks I met out here during our demo drives,” Dyson said. “It was great of RaceCo to make this happen and it was a pleasure to make these friends of RaceCo our friends as well. I’ve always loved Miller Motorsports Park, so I made sure I got the assignment to come here.”

Dyson noted that the SP/300.R represents a new and very different approach to motoring fun than Caterham’s traditional Seven. “The Seven traces it heritage back to Colin Chapman’s original Lotus Seven from the mid-1950s. The SP/300.R looks like a slightly smaller version of the cars we race in the ALMS series and it has the same 21st-century technology. It is the perfect car for the trackday driver who’s been driving a hot street car or a vintage racecar and is looking to go faster and spend less money. The SP.300.R is the next logical step.”

Here are some of the technical details. With its strong and safe high-sided aluminum-honeycomb monocoque chassis and separate front-end crash box, the SP/300.R weighs only 1275 pounds, but provides unmatched driver safety. And with 300+ horsepower from its supercharged two-liter, four-cylinder, dry-sump lubricated Duratec-based engine, this car boasts an impressive power-to-weight ratio that few if any production-based trackday cars can match. All those numbers equal more numbers: 0-60 in 2.8 seconds and a top speed of 165 mph.  The SP/300.R’s race car technology includes a mid-engine chassis layout, pushrod-actuated/rocker-arm suspension with coil-over springs and adjustable shocks, airjacks and adjustable front and rear rollbars. Power is transmitted to the centerlock 13-inch Formula 3-style wheels and racing tires through a Hewland FTR six-speed sequential gearbox with error-proof paddle-shift (the clutch is only used when starting or stopping the car) and a limited-slip differential.

The car has a few tricks up its eight-piece coachwork sleeve as well.  Lola developed the aero package by using computational-fluid-dynamics technology to produce a car with an optimized high-downforce, low-drag aero signature.  The SP/300.R features AP Racing disk brakes with cockpit-adjustable front-rear balance, an adjustable carbon composite rear wing, a downforce-generating aluminum rear diffuser (990 pounds at 150 mph), and at the front end the splitter and carbon-fiber dive planes are aerodynamically optimized to balance all that downforce.

The SP/300.R features a genuine two-seat cockpit, just in case your friends want to see what it’s like being strapped into a prototype-style race car for a few quick laps.  The twin roll hoops and front crash structure are MSA spec, and the 30-gallon fuel cell meets FIA specifications.  While the six-point harness keeps you strapped in the cockpit, you can feel free to adjust the balance of the AP Racing brakes.

 

Want to see it for yourself?  RaceCo is going to be home for a few months to one of Dyson Racing’s Caterham SP/300.Rs.  Get a hold of them and get out there to take a look at this amazing machine.
