Confidence
The Praga R1 takes the established conventions of racing car design and amplifies them. When we talk about lightweighting, we do so with the authority of a brand that has designed and built a proven bespoke carbon fibre chassis.
When we talk about aerodynamics, we do so as a company that understands that a racing driver requires grip not only for outright speed, but for confidence, driver feel and overtaking performance.
And when we talk about strength, integrity and reliability, we do so as a company that has established these as guiding principles.
We don’t do things differently just for the sake of it. We analyse, improve, test and evolve.

Lightweight philosophy
Brake later, take corners faster, steer with more confidence and accelerate more freely. Enjoy the competitive advantage of a truly lightweight racing car with the Praga R1. Being lighter also means less tyre wear, reduced mechanical stresses, and therefore lower maintenance bills. We call that a win win.
AERODYNAMICS
You can tell by just looking at the R1’s bodyworkthat it has been shaped to manipulate the airitself. The result is an advanced aerodynamicpackage; evolved and improved to create grip,stability and agility. Recent developmentsto the R1’s aero package have deliveredan improvement in the R1’s sensitivity to rideheight adjustments, and underfloor modificationshave optimized overall aerodynamic balance.
3G LATERAL FORCE
Continuous improvement using advanced CFD tools has increased downforce and reduced drag. Yes, the R1 can generate close to 3G of lateral force in corners – but we prefer to talk about how we’ve engineered the aerodynamics to give you the confidence to approach your limits lap after lap.
Easy to maintain
Want to run the car with a single mechanic? No problem. For track days and testing, the Praga R1 has been designed to be operated by one person. For a race weekend, you may choose more support – but the essential fact is that the R1 is engineered from the outset for easy set-up and on-track maintenance.
LOWRUNNING COSTS
Your rivals will envy your running costs.The R1 has been developed for maximum reliability over a racing season and beyond thanks to parts and systems that have undergone an extensive testing and durability programme. Question is, what will you invest the savings in? Tyres? Driver training?Or maybe simply more racing…

Reliable performance, courtesy of a highly efficient four-cylinder engine built by the specialist racing division at Alpine Renault, and honed with bespoke engineered Praga parts for increased driveability, power and torque.
With sufficient tank capacity for around 90 minutes of racing, the fuel system is optimised with two main pumps – with one used as a spare. The low-pressure pumps propel all 92 litres of fuel to the injection system, ensuring no scavenging issues when fuel levels reduce. Minimising these variables means that endurance racers and team-managers can accurately predict fuel consumption over a race distance – long or short.
Custom-made Hewland JFR six-speed gearbox with interchangeable gearsets for circuits of all lengths and configurations. Bespoke paddle-operated system with flat-shift and auto blip included, plus a lightweight triple-plate competition clutch.
We understand drivers. And we know that feel is a crucial element in operating a racing car – the ability to immediately sense the behaviour of the car in the corners and braking zones. It’s with this in mind that we have evolved these areas of the car with second generation components including roll bars, lightened uprights, and revised steering geometry. The result? Trust, confidence, and a car that obeys your commands.

Delivering Results Today
The Praga brand was founded over 100 years ago and the company has since designed, engineered and manufactured hundreds of thousands of automobiles, trucks and buses, motorcycles, airplanes, military and agricultural machinery. Consumer-driven model line-upsand bespoke solutions to challenging technical briefs were introduced across Praga’s portfolio.
Praga became one of Central Europe’s biggest automotive engineering firms in the first half of the 20th Century and grew to become one of Czechoslovakia’s “big three” brands.
