Quick Takeaways
  • The symposium agenda confirms a concentrated industry focus on hybrid, electric, and hydrogen powertrain pathways for the next decade.
  • OEMs and tier-1 suppliers will use the platform to disclose near-production technologies spanning ICE efficiency, electrification, and hydrogen combustion.
On January 5, the official schedule for the International Vienna Motor Symposium 2026 was announced, confirming that the 47th edition of the event will take place from April 22 to 24, 2026. The symposium will host close to 100 technical presentations and welcome industry participants from more than 20 countries, including Germany, Japan, China, India, the United States, and several European and Asian automotive hubs.
The International Vienna Motor Symposium 2026 will place a strong emphasis on next-generation hybrid powertrains, battery-electric systems, and advanced combustion technologies. Presentations will cover highly efficient hybrid architectures, new electric drive platforms, and series-production components such as wheel hub motors, alongside high-performance hybrid concepts derived from V8 and V12 base engines.
A major technical highlight will be the unveiling of a new hybrid gasoline engine jointly developed by AVL and Chery, achieving 48 percent thermal efficiency in series production. The system is positioned as a significant step forward for range extender applications. Toyota will introduce its next-generation hybrid system designed specifically for plug-in hybrid vehicles, while Volkswagen AG will present its latest hybrid technology platform. BMW is set to reveal technical details of its new GEN6 battery-electric drive for the first time.
Several OEMs will focus on advanced internal combustion engine evolution integrated with electrification.
  • Tata Group will present a new family of 1.5-litre four-cylinder gasoline engines
while Audi will unveil a new V6 TDI paired with a powerful hybrid powertrain. Mercedes will outline the evolution of its inline six-cylinder diesel engine, the OM 656 Evo, combining modern diesel engineering with electrified efficiency enhancements.
High-performance hybrid systems will also feature prominently at the symposium. Porsche will present a hybridised bi-turbo six-cylinder boxer engine developed for the new 911 Turbo S. Mahle will showcase a V12 hybrid powertrain aimed at hypercar-level performance, while Lamborghini will introduce a high-output hybrid system developed for its Temerario GT3 super sports car.
Hydrogen-based powertrain technologies will form another key focus area. Cummins will present a hydrogen combustion engine designed for extremely demanding applications, while FAW Group will highlight hydrogen solutions for decarbonising heavy commercial vehicles. AVL, in collaboration with Scania, will demonstrate its H2 HPDI system, enabling high-pressure direct hydrogen injection with efficiency levels approaching 60 percent. In addition, AVL will present Copper Car, a rapid software regression testing solution for high-voltage electric vehicle systems.
