Renault unveils next-gen Scénic engine

Renault has introduced an all-new gasoline direct injection turbocharged engine co-developed by the Renault-Nissan-Mitsubishi Alliance and Daimler. The new unit, which will be initially included in the 2018 Scénic and Grand Scénic, is available in three power outputs and will be progressively added to the full 2018 Renault line-up.

“Our new gasoline engine embodies all the expertise of Groupe Renault’s engineers, the Alliance and our partner Daimler,” said Phillippe Brunet, vice president at the Alliance. “It meets the quality standards of both the Alliance and Daimler, with more than 40,000 hours of testing. Compared with the Energy TCe 130, the new Energy TCe 140 delivers 35Nm additional peak torque, which is available across a broader rev band, from 1,500rpm to 3,500rpm.”

The new gasoline engine block, coupled with manual and EDC dual-clutch automatic transmissions, will generate between 115ps and 160ps depending on the variant. The Energy TCe 160 option offers a maximum torque of 260Nm in the manual gearbox and 270Nm in EDC gearbox from 1,750rpm up to 3,700rpm. However, the Energy TCe 115 – available in manual transmission only – has 220Nm of torque at 1,500rpm.

Thanks to a specific combustion chamber design, the fuel and air mix is optimized, this means the Energy TCe 140 and 115 will output 122g/km of  CO2 while delivering 5.4 l/100km (52.2mpg) on the NEDC cycle. In addition to a redesigned combustion chamber, the pressure of the direct fuel injection has been raised by 250 bar and ‘Dual Variable Timing Camshaft’ technology controls the intake and exhaust valves according to the engine load. The result is more torque at low revs and more torque available linearly at high revs, meaning better mid-range response.
