CO2 changing focus The global economic crisis could trigger novel engineering solutions and the need for comprehensive testing. ZEVs, fuel cells, and high-tech engines Only 10% of cars on Europe's roads by 2020 may be zero-emissions vehicles, but Mercedes-Benz is supporting future ZEV and other advanced technologies with an undiminished R&D budget. Warning signs Design and engineering lead-time tightening may be strangling innovative thinking, says Royal College of Art's Harrow. The decade ahead Renault anticipates that a majority of its powertrains will be downsized to the 0.9- to 1.2-L range and that electric cars will appeal to 30% of the buying public. Automatic for the people Automatic-shifting dual-clutch transmissions are poised to grab share from traditional transmissions thanks to their combination of efficiency and convenience.
