New 1.5, 1.6 and 2.0L diesel engines will also improve efficiency, meet new EURO VI emissions standards and cut CO2 by 20-25 g/km compared to existing units. Starting sometime in the next year, Renault will also replace existing automatic transmissions with new dual-clutch units that are lighter and more efficient.
Also high on the list are electric drive systems which Renault calls "an inevitable answer." Renault is working with alliance partner Nissan and its battery joint venture Automotive Electric Supply Corp (AESC) to try and make affordable, durable electric cars a reality. While an important part of the answer, Renault doesn't expect EVs to replace all internal combustion vehicles in the foreseeable future. Check out the full release from Renault at the link.
