A new facility at the Vehicle Emissions Laboratory of the JRC site in Ispra, Italy was opened today by European Research Commissioner Janez Poto nik. The latest JRC VELA 7 facility is the most advanced in Europe to test fuel consumption and related emissions of full size trucks and buses under simulated road driving conditions within a broad, realistic temperature range. To conduct the tests, the laboratory can host vehicles up to 40 tons and 12 metres and simulate wind drag, tyre/road friction as well as full drive cycles. VELA 7 will provide sound scientific data needed to support new legislation e.g. the upcoming Euro VI guideline which is aimed at reducing emissions of heavy duty vehicles.
