To give consumers a clear orientation when choosing an economical car that is as green as possible, the 13th round of the ADAC EcoTest (2003) added a fundamental innovation: cars that won a recommendation in the lab test had to submit to additional emissions measurements on the road (real driving emissions).
In the strictest ADAC EcoTest to date, the Toyota Prius 1.8 Hybrid Executive delivered convincingly low fuel consumption and exhaust emissions. The measurements were 1.7 l urban, 3.9 l extra-urban and 5.4 l motorway, each over a distance of 100 km, CO2 emissions of 113 g per km.
