The New R1Improved

The Praga R1 is a true revolution in sports racing cars. There is no other racing car like it. Nothing blends together a unique carbon fibre chassis with highly-evolved aerodynamic bodywork and bespoke engineering quite like it.

Furthermore, no car in its class can match the Praga R1’s safety features and cost-effectiveness.

Engineering
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.

Slide

AERODYNAMICS

You can tell by just looking at the R1’s bodywork that it has been shaped to manipulate the air itself. The result is an advanced aerodynamic package; evolved and improved to create grip, stability and agility. Recent developments to the R1’s aero package have delivered an improvement in the R1’s sensitivity to ride height adjustments, and underfloor modifications have optimized overall aerodynamic balance.

Slide

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.

Slide

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.

Slide

LOW RUNNING 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…

Safety
Features

There is a reason that the fastest racing cars in the world employ a carbon fibre chassis: safety. The R1 far exceeds recognised standards and we are confident that it is the safest car in its class.

Carbon monocoque

With Zylon bodywork panels manufactured to prevent penetration and a second generation monocoque improved with additional layers of carbon fibre, the R1 driver can feel confident and secure in an enviroment designed to keep them safe.

Zylon Composite/aluminium panel Aluminium honeycomb

Crash structures

Both the R1’s crash structures (front and rear) are made from high-strength carbon fibre and tested to extremes beyond what is to be expected in competition.

Front crash box Survival cell Rear crash box Side-mounted crumple zone

Interior safety

The R1 driver sits between the front and rear crash structures and side-mounted crumple zones for increased safety performance. Plus both the pedal box and collapsible steering column are designed to reduce risks inside the R1. Removable interior door hinges are also fitted as standard.

Fuel cell
and fire extinguisher

A high-specification foam-filled FIA approved fuel cell comes as standard, plus a mechanically-operated fire extinguisher system for both the engine bay and the cabin.

Endurance lighting

For turning night into day during those challenging endurance stints after dark, the R1 features two pairs of improved high intensity LED headlights, carefully selected for colour temperature to maximise sharpness and definition. These lights are manufactured from 3D printed carbon fibre and nylon composite and are watertight to IP65 standards.

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.

#winninginstinct

In 2020, the Praga R1 scored overall victory in the highly competitive Britcar Endurance series.

With 7 wins of 9 races and scoring fastest laps and pole positions in the process – Praga outpaced far more exotic and expensive-to-run machinery.

Eligible
Race Series

Praga works closely with governing bodies and race organisers all over the world. The R1 is eligible for a number of highly competitive and popular championships – with more to be revealed. If your chosen championship is not listed, please get in touch.

Praga plan to expand our race programme significantly across Europe, USA, Middle East, Asia-Pacific and Australia as well as launching a unique, one-make race Praga R1 race series in UK/Eu.

Partnerships on the track

Praga has a technical partnership with a Formula 1 team engineering division and works closely with driver Romain Grosjean. Praga also recently announced Josef Král, one of the Czech Republic‘s most successful and influential racing drivers, as Head of Motorsport.

All of these assets will be utilised across our motor racing activities and will integrate with Team Praga.

114 Years of Innovation...
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-ups and 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.
