Vauxhall’s Signum fitted with the new 2.2 direct injection petrol engine is the most environmentally friendly petrol car, according to this year’s European ADAC/FIA Foundation Eco Test.
With 79 points, the Signum 2.2 Direct topped the family car section of this year’s results.
The EcoTest is designed to provide a fair and meaningful assessment of the environmental performance and impact of cars. The tests are based on those developed for emissions legislation in Europe and then extended to cover a wide range of real driving situations.
The FIA Foundation reports: "No stylised procedure fully reflects the environmental impact of a car in the wide variety of driving behaviours. However, cars that perform well in these tests provide less environmental impact than cars which perform less well."
The EcoTest, which was carried out by the ADAC on behalf of the FIA Foundation, tested 113 vehicles in the mini, small, compact, mid-size cars, upper mid-size and luxury car segments. The highest possible rating was 90 points or five stars; both Signum and Vectra earned four stars each. The Corsa ECO was awarded five stars in 2003.
Signum’s 2.2 direct injection engine has a power output of 155 hp and makes 220Nm of engine torque at 3800 rpm. On a combined fuel cycle, 34.9 mpg is returned while the CO2 figure is a creditably low 194 g/km.
Adding to Vauxhall’s environmental credentials further, the Signum and Vectra are now also available with the new 1.9 CDTi diesel engine, in 120 and 150 hp versions. Both engines meet Euro 4 and can be equipped with a maintenance and additive-free diesel particulate filter (DPF).
