Praga R1

The first affordable race car of the 21st centuryYou don’t need a radical revolution just our progressive evolution.Nowadays, affordable racing is thought of as second level engineering. We think of it differently. High-endmaterials are no longer restricted to factory teams, and the ingenious simplicity of tubular space frame simplycannot compete with the strength to weight ratio of carbon fibre monocoque. Add in non-compromised, allroundsafety, mix it with reliability, and wrap it in excitement and emotion. These are the visions behind R1.Does this sound like the last century to you?We live in the 21st century and we are aware of it.

The perfect balance between attractivedesign and aerodynamic efficiency.We wanted the car to be stunning. But that isn’t enough withoutthe added value that ensures our primary objective – to go fast.Combining the two might seem difficult, until you realize thatwell executed aerodynamics creates state of the art racing.R1 can in fact generate up to 1,5x times its weight through itssophisticated aerodynamics. Enhanced traction and the overallcapability of the car to go fast around the corners is whatdifferentiate R1 from its competitors.

Where standard racingsafety is not enough.Although we think light, there is no compromise in terms of safety. Racing rules dictate tomount a nose cone crash box on to the car. We think this is not enough. R1 crash safetystructure is composed of bespoke honeycomb carbon fibre monocoque, carbon/Kevlarstrengthening flooring, front and rear crash boxes, and side mounted crumple zones. Anindependent test centre in Cranfield (UK) carried out a test of R1’s monocoque accordingto FIA CN standard and the monocoque survived with absolutely no damage at all.Coupled with the racing standard six point seat belt, neck restraint, helmet side support,FIA approved fuel cell, polycarbonate windows, and an integrated fire extinguishersystem, you’ll never feel so safe in a race car.It is good to know that when everything else“disappoints“, your safety is not compromised.

Out of the first 50 starts, we have 100%finish score. You get the picture…

Affordable, does notmean boring!We know what it costs to race. You spend money on a car, but that is where your expenses merely begin.So we thought about what we could do to make racing more affordable, and here’s what we did:• The R1 cost is comparable to other race cars, but in termsof its technology you’ll be left with no doubts about its valuefor the price.• Lightweight and aerodynamically efficient design allows fora stock engine to be used. Don’t get us wrong, the enginecomes from Formula Renault, but the difference comparedto its stock origin is only the dry sump for a lower centreof gravity. That means 3-10 times longer intervals betweenengine rebuilds than the racing standard.• Maintenance requires race mechanics, which can oftenstretch the budget. The R1 is designed to be maintainableby a single mechanic, keeping those costs minimal.• Suspension setup is optimised to enhance traction whileminimise tyre wear. Aware of tyre cost, we did what wecould to give you more running time on a single set.• R1s parts are designed and build to last. Less replacementmeans less cost and if you do need to replace a part youwill find more than competitive prices. We believe thatquality matters.• Crashes and scratches? Carbon fibre doesn’t mean justlightweight, it also means durable. And R1 is completelycarbon fibre.• Reliability? Out of the first 50 starts, we have 100% finishrate. You get the picture.Where others reach deep into their pockets to keep their engines running,the heart of your R1 will last you throughout the season.

R1 is meant to beraced, not serviced.We don’t have patent on being smart. Why reinvent thewheel? Reliability is a question of trial and error and so wemade a deal with those who tried. In the 21st century, thereis no shortage of bespoke motorsport products from greatproducers and we gladly accept the knowledge coming fromtheir experience. AP brakes, Hewland transmission, RenaultSport engine, Koni dampers, Cosworth Pectel – ECU and aformula style steering wheel, ATL fuel tank, Sachs clutch,OMP fire extinguisher system, and KMP pneumatic paddleshift. We take reliability seriously.Utilizing what works in the bestpossible way is our solutionto keep the costs down whiledelivering incredible performance.

We admit that R1 is not just aboutpurpose, it is also purposefully beautiful.The design was mainly inspired by the legendary 24hour Le Mans prototypes, but theinspiration did not stop there. Raindrops gave it aerodynamic efficiency, fighter jets elegantfunctionality, advanced materials an eye-shattering shape and the Star Wars similarities a bitof timelessness. We wanted you to feel the functionality and emotions in perfect harmony,the pre-load of energy in all the curves mixing with the lightness of air passing by. We simplywanted it to be breath taking. Whether we were successful, we’ll leave that up to you…

Race cars are an art like paintings. No wonder people like to hang theirpictures on their walls. And we believe that R1 will cover a lot of walls…

Ready for racingIt is not just another weekend racer but has been designed and approved according toInternational Sporting Code regulations Appendix “J” Article 277 and crash tested accordingto the CN regulations. The R1 is therefore eligible for any of the FIA events supporting E2-SCsports cars, allowing you and your friends to feel the full thrill of competiting in motorsport.
