Renault, for Symbioz the E-Tech Full Hybrid 145 engine

ROME (ITALPRESS) – Symbioz, the C-segment SUV launched by Renault, can also count on the E-Tech full hybrid 145 engine, very efficient and economical to use, offering all the comfort and silence of electric driving in the city, without charging constraints. Thanks to Renault's E-Tech full hybrid technology, drivers can count on consumption reduced to a minimum for most routes, with little dispersion between the different driving modes. The E-Tech full hybrid technology, for which over 150 patents have been filed and which can count on Renault's experience in Formula 1, especially in terms of regeneration and energy recovery, offers dynamism and efficiency. Its so-called “series-parallel” hybrid architecture includes two electric motors (a 36 kW e-motor and an 18 kW HSG – High-Voltage Starter Generator – type starter motor) and a 1.6-litre, 94 horsepower 4-cylinder petrol engine, combined with an intelligent multimode transmission with clutchless dog clutch and a 1.2 kWh battery. The transmission has 4 gears for the petrol engine and 2 gears for the main electric motor. The E-Tech full hybrid 145 engine therefore offers up to 14 possible operating combinations between the petrol engine and the electric motor, for optimised energy efficiency. Starting always occurs in electric mode and it is possible to drive in the city up to 80% of the time in 100% electric mode, with a reduction in consumption that can reach up to 40% in the urban cycle compared to classic petrol engines. On the motorway, the architecture of the powertrain allows the combustion engine to drive the wheels directly, without the waste that consists of running the electric motors unnecessarily, as happens in traditional hybrid systems. Renault technology allows Symbioz to record the best fuel consumption in all circumstances, with a WLTP cycle estimated at 4.6 l/100 km. Since its launch, the powertrain has never stopped being optimised, especially in terms of software management, to improve fuel consumption and ease of use, especially on the motorway. Just like on the new Clio and the new Captur, Symbioz also features the new E-Save function, which is activated by pressing a button located to the left of the steering wheel. E-Save improves driving comfort and optimises fuel consumption, keeping the battery charge level at a minimum of 40%, so you can always count on enough electric energy to tackle hills without losing speed and overtake by relying only on the electric motor, without stressing the combustion engine. It also avoids sudden downshifts, often perceived as a source of unpleasant noise emissions. With E-Save activated, the number of forced downshifts that can have the unwanted effect of making the engine rev higher when driving on the motorway is reduced by 30 to 40%. Symbioz can also count on predictive hybrid driving, which allows maximum use of electric energy compared to thermal energy, to the benefit of consumption. This function is based on data from connected maps (Google Maps) and takes into account topography (climbs, descents, etc.), travel time and traffic. This data is processed in advance by the battery management system to make the most of the electric traction energy. A driving report is available in the form of a histogram with the details of consumption and distance travelled in 100% electric mode.
