Renault's first turbocharged, direct-injection petrol engine – the Energy TCe 115 – is particularly responsive. Thanks to peak torque of 190Nm, a figure worthy of a two-litre powertrain and available from as low as 1,750rpm, the Energy TCe 115 delivers the acceleration and mid-range response expected of a 1.6-litre engine.

'Square' engine architecture: takes up less space yet delivers the same performance
- Reduced friction: friction-related energy losses have been reduced, meaning that less fuel is required to deliver the same quantity of energy. Other benefits are longer engine life and enhanced robustness.
- Variable-rate oil pump: oil pressure is electronically monitored and adjusted as a function of how the engine is being used. The benefit to the customer is lower fuel consumption and CO2 emissions.
- Low-friction timing chain: this optimised timing chain is equipped with a hydraulic tensioner which keeps it permanently taut to minimise friction.
- Graphite-coated piston skirts DLC: (Diamond Like Carbon) coated cam followers, a technique that has been employed in F1 for some years. Benefits are significantly reduced friction and enhanced energy efficiency for uprated performance and improved fuel consumption.

Direct fuel injection: fuel is injected directly into the combustion chamber to optimise efficiency by carefully adapting the strategy as a function of how the engine is being used. The result is improved combustion and, consequently, lower fuel consumption and CO2 emissions. Double cam-phasing

Variable Valve Timing (VVT): combined with an integrated turbo manifold, VVT ensures that maximum torque is available at low engine speeds and across a broad rev-band.

Stop & Start with ultra fast start-up: at a standstill, the system automatically detects the position of each piston and injects fuel into the most favourably-placed cylinder, in the same way as a cyclist presses on the uppermost pedal when pulling away. Re-starting is instantaneous. The energy required for frequent re-starting is recovered during deceleration and braking.
