Renault knows that radically curbing fuel consumption and CO₂ emissions is vital in today's world.

The brand already figures among Europe's three best-performing carmakers when it comes to average CO₂ emissions, and its sights are now set on moving to the top of the order. To achieve this objective, Renault is currently working on the development of low-emission and zero-CO₂ emissions vehicles in a determined bid to introduce as many effective technologies as possible at an affordable price. Its work on powertrains focuses on two main areas.

Renault is working on a new generation of turbocharged internal combustion engines, as well as on new automatic transmissions.

• 'Modular' TCe engines, with power outputs ranging from 90 to 115hp
  With the imminent switch to Euro 5 and Euro 6 legislation, petrol engines are poised to become an increasingly attractive proposition, a trend anticipated by Renault's new TCe powerplant family. Scheduled for launch in 2012, it is expected to account for 85 per cent of Renault's petrol engine sales in 2015. These 'modular' engines will have a cubic capacity of between 0.9 and 1.2 litres and will be available in three- and four-cylinder form with power outputs ranging from 65 to 85kW (90 to 115hp). A number of vehicles equipped with these engines will emit less than 100g of CO2/km.

• The future 1.6 dCi 130 engine
  The forthcoming 1.6-litre engine will boast a power output of 96kW (130hp) from launch. It is being co-developed within the framework of the Renault-Nissan Alliance and is scheduled for release in 2011. Its CO₂ emissions will be 25g/km lower than those of a current 1.9-litre diesel.

• Twin-clutch transmission
  Renault will be in a position to release a twin-clutch transmission on the market in the course of the next year. Twin-clutch transmissions combine exemplary gearshift quality with lower CO₂ emissions for the same fuel consumption as that of a manual gearbox.
  

All-electric vehicles do not produce any CO₂ emissions resulting from their use on the road.

Renault is aiming to become the industry leader in the realm of mass-market electric vehicles. The Renault-Nissan Alliance is consequently developing a comprehensive range of all-electric powertrains, with power outputs ranging from 50 to 100kW (70 to 140hp).
