High-performance powertrains (engine and gearbox) consume less energy and pollute less.

Automatic transmission and fuzzy logic


Renault’s ultramodern automatic transmissions implement fuzzy logic capabilities to adapt to the driver's temperament and driving conditions.

Automated manual transmission (AMT)

AMT has the great advantage of only consuming energy when actually changing gears, which makes for lower fuel consumption.

Common rail

The common rail fuel injection system reduces fuel consumption, improves engine efficiency, and minimizes emissions of greenhouse gases.

Downsizing

Using technologies such as turbocharging, the same performance can be obtained from a smaller engine, which is more efficient and emits less greenhouse gas.

Piezo-electric injectors

Piezo-electric injectors under electronic control optimize engine efficiency by making very precise adjustments in the amount of fuel injected.

Camless motors

The traditional camshaft is replaced by electromechanical actuators, to reduce fuel consumption, improve pollution control and raise engine performance

Optimized combustion

Engine combustion optimization is a primary R&D objective, with considerable bearing on engine performance, fuel consumption and emission levels.

Turbocharger

Far from being a mere add-on, the turbocharger performs a vital function, in reducing fuel consumption and emission levels as well as boosting engine power.

"The traditional camshaft is replaced by electromechanical actuators, to [...] raise engine performance". Cool! Oare anduranta sistemului care ar fi?

Ma incanta noutatile astea tehnice... Principiile sunt simple, in general, dar elementele fizice... Mie mi-a ramas de vreo doua ori pedala de acceleratie blocata la podea (datorita potentiometrului, banuiesc, nu in covoras) si am cam inceput sa ma indoiesc de chestiile prea complicate, mai ales ca sunt constient ca, din ratiuni de pret, nu se prea pune accent pe sisteme de backup. Oricum, Renault are niscaiva inovatii la activ (pornind de la design, trecand prin siguranta si pana la... nu mai stiu ce) astfel incat poate, printre surprize nu tocmai placute (pe piata din Ro), sa mai dea cate o lectie concurentei la unele capitole.
