The Volkswagen EcoRacer is an innovative mid-engine sports car concept first unveiled at the 2005 Tokyo Motor Show. It was built to prove that high-performance sportiness and extreme fuel efficiency could coexist seamlessly in a single package
The defining feature of the EcoRacer is its highly versatile, modular body made entirely of carbon-fibre reinforced plastic (CFRP).
The car can be manually converted into three distinct vehicle types in just a few minutes:
Coupé: The baseline configuration, complete with a hardtop roof and a rear hatch.
Roadster: Removing the T-bar roof panels and the rear hatch converts the car into an open-air targa sportster.
Speedster: Releasing a special catch allows the driver to completely remove the front windscreen and its frame, replacing it with a low-slung flyscreen.
Powered by a mid-mounted 1.5-litre TDI turbodiesel four-cylinder engine.
It generates 136 horsepower (100 kW) and 250 Nm of torque.
Power is routed to the rear wheels via a DSG dual-clutch automatic gearbox.
Thanks to its lightweight carbon-fibre monocoque chassis, the vehicle weighs a mere 850 kg.
The "Eco" in its name comes from its astonishing fuel economy. It consumes just 3.4 litres of fuel per 100 km (equivalent to roughly 69 mpg US / 83 mpg UK).
The concept also showcased Volkswagen's experimental Combined Combustion System (CCS), which allowed the engine to run cleanly on synthetic fuels to meet strict environmental standards.
While the EcoRacer never entered production, elements of its minimalist interior layout later influenced tech like Audi’s Virtual Cockpit, and its spirit lived on in Volkswagen's ultra-efficient, limited-run XL1 hybrid.
