Praga targets road and track market with Bohema
Sports prototype manufacturer Praga has launched the Bohema, the company’s first road car, albeit one with a heavy track bias. Clocking in at sub-1,000kg, the mid-engined two-seater has been built to be capable of GT3 race car lap times.
According to the company, Praga ambassador Romain Grosjean challenged it to deliver an uncompromised two-person road/track performance car. “I was astonished by the Bohema’s amazing performance on track, its accessibility on road, and the ease of transition between the two,” said Grosjean at the launch.

Powertrain focus: Czinger 21C – the 3D printed hypercar
A decade ago, the idea of 3D printing a car would have seemed like an outlandish idea. In 2023, it is very much a reality thanks to the efforts of Czinger, the California-based manufacturer of the 21C, a 1300hp+ hybrid hypercar that makes extensive use of additive manufacturing (AM) technology across both its chassis and engine. Czinger is an offshoot of Divergent 3D, a company looking to disrupt the automotive manufacturing industry with its DAPS (Divergent Adaptive Production System) concept.
AVL develops hydrogen-fueled, 2.0-liter race engine
AVL Racetech, the motorsport department of AVL, has presented a hydrogen-fueled internal combustion engine prototype. Based on a 2-liter turbo engine, it is equipped with what the company calls intelligent water injection, which enables it to achieve high performance levels. The prototype is the first racing engine that AVL Racetech has developed and built in-house (although the department has been responsible in one way or another for many confidential race engine development projects over the years).
New tooling material offers cost-effective composites pattern solution
UK company Base Materials has launched Ares 770, which it describes as a novel cost-competitive tooling material. The proprietary resin system, which is made from syntactic materials, is designed for the manufacture of master models and patterns used in the production of carbon-fiber parts, and for vacuum forming and thermoforming applications.
The company says that the material is suitable for use at temperatures up to +130°C and boasts a fine surface structure, low coefficient of thermal expansion, excellent dimensional stability and an inert surface for wide-ranging compatibility.
F1 backs new, all-female junior series dubbed F1 Academy
Formula 1 is set to launch an all-female driver category, the F1 Academy, in 2023 to develop and prepare young female drivers to progress to higher levels of competition – including W Series, Formula 1, Formula 2 and Formula 3.
The series will consist of five teams run by current F2 and F3 teams, each entering three cars to make up a 15-car grid. The first season will comprise seven events with three races each, plus 15 days of official testing.
Australian Supercars to broadcast driver’s eye-view from helmet cameras

Alexandros Miotto Haristos, COO of Racing Force Group, commented, “The Repco Supercars Championship is yet another top motorsport series to adopt the Driver’s Eye technology to enrich the show with its spectacular immersive experience.”
David Tunnicliffe, Supercars head of broadcast, added, “The camera will be positioned at eye level on the protective padding on the inside lining of the helmet, transmitting live footage from behind the visor directly to television screens.
Interview: Arnaud Martin, chief officer, inverter systems and motorsport, Helix
Glance under the hood of any EV or hybrid hypercar and there is every chance you will see hardware from UK-based Helix, which many will have known previously as Integral Powertrain. From the Aston Martin Valkyrie, though the Czinger 21C to Triumph’s TE-1 motorcycle and NIO 333’s Formula E racer, Helix is consistently at the cutting edge of high-performance electrification.
Professional Motorsport World caught up with Arnaud Martin, chief officer responsible for inverter systems and motorsport activities at the company, to find out how Helix is reorienting its business and technology to take best advantage of the ever-evolving EV landscape.
