Less than a month before the IAA Transportation trade fair dedicated to commercial vehicles, UTAC is presenting its 4-wheel drive VTEC (Variable Temperature Emission Chamber), which allows emission testing on a new variety of vehicles. This chamber located in UTAC Millbrook in the UK can accommodate larger, heavier and more powerful vehicles and offers the possibility to test electric, hybrid, thermal and hydrogen engines.

This new variable temperature emission chamber allows for more efficient and accurate testing, while reducing set-up times. The four-wheel drive and triple-axle capabilities make it possible to perfectly simulate driving in real conditions. VTEC allows temperature-controlled emissions testing for a wider range of buses, coaches, off-road vehicles and passenger cars in a temperature-controlled environment (from -20°C to 50°C). It can be adapted to vehicles with a wheelbase of 8 m and an axle load of 20 tonnes.
