An assessment of vehicle fleet structure, fuel consumption, and emissions, with comparisons to the EU-28 market and other key global markets, and to the German auto sector in particular.
Compares official fuel consumption values with real-world performance for 20 popular vehicle models. Officially, fuel consumption gains in these 20 models ranged from 8% to 30%. But on-road measurements indicate that 8 of the 20 showed little to no improvement in real-world fuel efficiency.
