410 hp From 2-Liter Displacement – Prototype of the H2-ICE Race Engine From AVL RACETECH Proves Itself On The Testbed
The motorsport department of AVL is celebrating the next milestone on the road to a zero-emission future of motorsport. The prototype of a hydrogen-powered, two-liter turbo engine –
built by AVL RACETECH – was put through its paces on the testbed and confirmed the top values calculated previously in simulations: with a specific power density around 205 hp per liter (150 kW per liter),
the engine achieves a highly competitive level in the world of motorsport. This is made possible by, among other things, an intelligent PFI water injection to moderate combustion.
Up until now, hydrogen combustion engines (H2-ICE) have been somewhat renowned for low performance figures and lean-burn. AVL RACETECH is banishing that “preconception”. Over the past few months, the motorsport
department at AVL has developed an innovative H2 racing engine in cooperation with the Hungarian HUMDA Lab. For AVL RACETECH it is the first race engine under its own name. On one of the engine testbeds modified for
the use of hydrogen at the AVL headquarters in Graz, a prototype of the hydrogen-powered, two-liter turbo engine achieved a top figure of 410 hp (301.7 kW) with an engine speed of 6,500 rpm. The engine generates 500 Nm of
torque at 3000 - 4000 rpm, that corresponds with a mean pressure (BMEP) of 32 bar.
The features include an intelligent PFI water injection, which injects additional water into the engine’s intake air, in order to avoid unwanted premature ignition, which can damage the engine. The air-fuel ratio (lambda)
is 1 (stoichiometric combustion), meaning it is no longer in the lean range. The air demand, which is lower than with lean combustion, is covered by using a wastegate turbocharger designed specifically for that purpose.
AVL had performed detailed simulations in advance, which displayed an excellent correlation with the results recorded on the testbed. The next milestone in the development is to test the new engine concept in a car on the racetrack.
Project leader Paul Kapus, Manager Development Spark Ignited Engines: “At the end of 2022, we announced for the first time that we would be working on a two-liter,
hydrogen-powered racing engine with stoichiometric combustion and PFI water injection. Our goals were 500 Nm of torque and an output of up to 300 kW (specific output 150 kW/l).
We are proud to have been able to validate those figures on the testbed.”
Ellen Lohr, Director Motorsport AVL: “The results achieved by our H2 racing engine confirm that we are able to deliver an extremely competitive package with this technology.
The goal of AVL RACETECH is to lead motorsport into a sustainable future. With the development of the first racing engine developed under our own name – a high-performance H2 ICE –
we have taken another step closer to achieving this vision.”

who we support through our ambassador program – from preparing them for races in our simulator to support them with our race engineers at the track.
Born in 1997, Ferdinand was the first participant on our young driver program. The Austrian amassed a multitude of victories and pole positions in the Euroformula Open, FIA Formula 3 and in the LMP2 class (Le Mans Prototype) at the Rolex 24 Hours of Daytona, before making his DTM debut in 2019. After a second season in the renowned sprint series, he successfully focused on endurance racing in 2021: He was champion in the Asian Le Mans Series, won his class at the 24 Hours of Le Mans, and crowned his outstanding LMP2 season with the title of FIA World Champion.
Tatiana (born 1993) decided at just nine years of age that she wanted to be a professional racing driver. Having cut her teeth in karting, the Columbian has achieved her big goal in various racing series, including Super Formula Japan, FIA Formula 3, FIA Formula 2, the European Le Mans Series (ELMS), and the FIA World Endurance Championship. In 2022, she lines up in the NTT INDYCAR Series. Tatiana hopes her passion will inspire other young girls, in particular. She is passionate about making motorsport a more diverse and integrative environment on all levels.
Finn (born 2004) made the step up to automobile racing and attained his international racing license in 2020 as a multiple karting champion. The youngster took his first steps in GT4 racing, where he immediately impressed and claimed class victories. In 2021, Finn became the youngest driver ever to make his debut in an Le Mans Prototpye (LMP3) in the Michelin Le Mans Cup. His team, Phoenix Racing, is a championship-winning team, which has been a familiar name in motorsport for 22 years. In 2022, Finn lines up for top team United Autosports in the LMP3 class within the famous European Le Mans Series (ELMS).
Aliyyah and Yasmeen have one big goal: The twins want to take part in the famous Dakar Rally together. Their love of motorsport was handed down to them when they were born in Dubai in 2004. Their father, two-time European truck racing champion Martin Koloc, is a true motorsport legend, whom they are attempting to emulate. And with success: At the age of just 16, Aliyyah became the youngest ever winner of a truck race. In 2022, the Dakar Sistaz line up in various racing series, including the FIA Middle East Cup for Cross Country Bajas, the EuroNascar Series, and selected GT3 and GT4 races.
Liam (born 2004) and his brother Jonas (born 2005) are among the best young Germans when it comes to off-road racing. Their motor racing career began in the German Autocross Championship, in which lightweight cross buggies go head to head in short sprints on gravel and mud tracks. In 2019, Liam was crowned German champion in the Juniorbuggy category, with Jonas runner-up. The Müller Brothers’ big dream is the World Rally Championship. On their way there, they are contesting selected rounds of the Mitropa Europacup and the German Rally Championship in 2022.

Launched by Ferdinand Habsburg and the Green Future Project in 2021, the “Drive Fast, Act Faster” program is helping the motorsport industry become more sustainable and make racing increasingly climate-neutral. As well as the general reduction of emissions, the program also offsets any remaining emissions by preserving biodiverse ecosystems. AVL RACETECH is supporting this goal by offsetting the complete CO2 footprint of its brand ambassadors for the entire racing season.
AVL and Ducati have been working closely together for several years. AVL RACETECH has been official technical partner of Ducati Corse since 2021. The motorsport department of the Italian manufacturer is responsible for developing the motorcycles that line up in MotoGP and Superbike competitions. Among other things, Ducati Corse uses the AVL CAMEO™ and AVL CONCERTO™ software solutions to analyze, visualize and optimize the performance of their race engines for MotoGP and other classes. And with great success: Ducati won the Constructor title in the MotoGP class in 2020 and 2021.
Founded in 2010 by Kuba and Wojtek Śmiechowski, the team entered endurance racing in 2016 with prototype cars and was able to claim early success. In 2019, Inter Europol Competition extended its involvement to cover the LMP2 (Le Mans Prototype 2) class, competing there for the first time in the Le Mans 24-hour race. The team debuted with the Oreca LMP2 #34 in the 2021 World Endurance Championship (WEC) – the first Polish team in the history of the WEC. They finished the season in an outstanding fifth place. Starting with the 2022 season, AVL RACETECH is the official team partner of Inter Europol Competition and supports the team, among other activities, in its preparation for the 24 Hours of Le Mans.
The expansion of our partnership with the Green Future Project will do more than just compensate for the
complete CO2 footprint of the AVL RACETECH brand ambassadors over the course of the 2022 racing season. In addition to
permanently protecting the acquired rainforest areas to preserve biodiversity, our technologies also make an important
contribution to environmentally-friendly mobility. Our involvement in the program is documented in the dashboard below.
