The new Radical SR1 XXR highlights this week’s edition of the Racecraft & Race Cars Roundup on Motorsport Prospects.
I also feature some valuable racecraft advice on how the driver inputs influence car balance, as well as tips for racing at Watkins Glenn and the Circuit Se La Sarthe, using the Garmin Catalyst to improve on-track performance and booking a test drive in a Revolution race car at Spa or Zolder.
All this and more in the Racecraft & Race Cars Roundup on Motorsport Prospects.
Racecraft Tips & Techniques
OptimumG‘s lead performance engineer Bruno Finco explains in the video above how the driver inputs influence car balance, and how to identify if the balance issues you have are coming from the driver or from the vehicle setup.
In Ross Bentley of Speed Secrets latest Ask Ross column, he answers the question, “In racing, what does it mean to “present” myself to the driver I’m passing?“
From ASMotorsports, join Coach Tomo in the video above for all the track tips you should know before driving Watkins Glen International in Watkins Glen, NY.
In Road & Track‘s The Winner’s Guide to a Lap of Le Mans, Tom Kristensen explains how to tackle Circuit De La Sarthe. “Kristensen, 55, has won almost 10 percent of the 24 Hours that have run. Here he takes Road & Track through a lap of this greatest of all racing venues, using a 2013 Audi R18 e-tron quattro for reference. He could communicate through semaphore or finger painting, and we’d still be rapt.”
In the video above, Motorsport UK Academy driver, Abbi Pulling, and Motorsport UK Academy Performance Coach, Tom Onslow-Cole, take on the tight and technical Bicester Heritage track to put the Garmin Catalyst through its paces. The professional racing duo see how much the driving performance optimiser can improve their lap time. Learn more about Garmin Catalyst here.
Race Car Developments
Radical Motorsport have announced that their entry-level SR1 will get an XXR upgrade. The changes include a new aerodynamic design in the form of a central LMP-inspired ‘fin’ and a new engine, the Generation 5 1340cc power unit from Radical’s bespoke engine facility.
“Although the entry-level racer, the SR1 XXR offers an outstanding package with unparalleled performance for the money, that will get you on the grid in a professionally administered race series. Racers with the SR1 XXR will still be eligible to race in the PRO SR1 classes of Radical Cup championships around the world, too.”
According to Goodwood Road & Racing, “the aim of the game with this new SR1 is increasing seat time, with the new fifth-generation RPE 1.3-litre engine now able to go for 25 percent longer between invasive maintenance intervals. Oil changes have moved further apart, with each change now allowing ten hours of driving rather than six.”
Unveiled in January after an intense development program covering 5,000 kilometers, Clio Rally3 made its first rally appearance as a zero car on the opening round of the French Gravel Rally Championship.
Powered by the four-cylinder 1.3-litre TCe 16-valve turbocharged direct injection engine, Clio Rally3 develops 260bhp and 415Nm of torque with a five-speed gearbox fitted with a limited-slip differential. On the outside, the aerodynamics have benefited from numerous synergies within Renault Group as Viry-Châtillon was able to draw on the expertise and computing resources of the BWT Alpine F1 Team in Enstone to design Clio Rally3’s rear wing.

To ensure it delivers on its promise and vision of a lightweight, track-only hyper sports car built around the W16 engine, Bugatti is beginning the next phase of development testing with its high-performance Bolide model.
“Limited to a production run of just 40 units, the vehicle is said to represent “an entirely new level of engineering, aerodynamic and technological innovation.” Starting with the quad-turbo W16 engine as the vehicle’s heart, Bugatti has then built an extremely lightweight body to encapsulate the powertrain. Despite its minimalistic design, the bodywork is highly functional and has been developed to provide maximum downforce and cooling. Furthermore, the combination of 1,600ps and a dry weight of 1,450kg results in the track car achieving a power-to-weight ratio which exceeds 1:1.”
