Improving our internal-combustion engines and developing the electric vehicle
Our Group is a European leader in low CO2 emissions and the first automotive group to go under the 115 g/km CO2 mark, a result achieved in 2013 with our passenger cars*. We aim to maintain this leadership and go under the 100 g mark in 2016 and 95 g in 2020.
To that end, our powertrain strategy is focused on two main points:
- the continuous improvement of our internal-combustion engines (by downsizing, reducing friction and improving combustion, notably by fitting our Energy engines on more of our vehicles) and our transmissions (in particular with the increased rollout of our EDC gearbox)
- the commitment to electric vehicles – the only technological solution offering zero emissions in use. We are working continuously to improve this technology and foster the development of charging infrastructure.

After introducing the first V6 turbo in Formula 1 competition in 1977, Renault Sport F1 (RSF1) has developed the Renault Energy-F1® engine, a V6 turbo featuring a dual energy recovery system (ERS), for the 2014 season.
Energy engines. The Energy range is based on three fundamentals: reliability, performance and energy efficiency. These three criteria apply as much to the Group’s production models as they do to its motorsport activities.
This shared DNA is reflected in the extensive dialogue conducted between the RSF1’s head office in Viry-Châtillon and the Group centers that design volume-production engines. RSF1’s experience in friction-reduction technologies has already benefitted the Energy engine family now fitted widely across the Renault range:
- diamond-like carbon treatment on the push rods
- pressure-vapor deposit process used on the piston skirts
- U-Flex oil ring, the geometry of which adapts to cylinder distortion to optimize efficiency and friction.
The end result is reduced fuel consumption and CO2 emissions – by as much as 25% – with no compromises on performance and driving pleasure.
30% of our production is delivered to partners
The powertrain business is one of the main sectors implementing industrial synergies in R&D with Renault’s partners.
The aim of the synergies is to pool development costs, absorb fixed production costs, and generate economies of scale in the industrial activities of Renault and its suppliers. More than 30% of our powertrain production is delivered to partners.
