Car-makers 'exaggerate' fuel efficiency: study
The gap has widened between the fuel-efficiency that carmakers declare for their models and the reality for drivers, with luxury German vehicles showing the biggest divergence, a study has found.
The research by the non-profit International Council on Clean Transportation (ICCT) found “real-world” carbon emissions for new cars based on fuel consumption are about 25 per cent higher on average than carmakers say, compared with 10 per cent a decade ago.
