In principle, a new hybrid, combining a gasoline engine and two electric motors, will allow 80% of the city's time to be driven, which would reduce fuel consumption by about 40%. It was developed by the Renault Nissan Mitsubishi Alliance and plans to be built on about 17 different models of the band.

The first car, which will receive the hybrid facility, will be the fifth generation of the Renault Clio. The car is waiting in Bulgaria in September, but the first hybrid modifications will be available next year.

Fuel economy technology uses a 1.6-liter direct-injection gasoline engine with a horsepower of just over 87 horsepower. The two electrical units are connected to it.

The main electric motor used to boost the car and generate power to charge the battery in the stop and inertia is 35 kilowatts (almost 47 horsepower). The second power engine is 15 kilowatts (just over 20 horsepower) and acts as a starter for the "ignition" of the gasoline engine. It also synchronizes the revolutions to provide a smoother gearshift, since the car has no clutch.

A curious feature is that two gears are used when operating a chain, and when using the gasoline engine, they have four gears.

The hybrid system of the alliance Renault Nissan Mitsubishi uses a battery of 2 kWh that is mounted under the back seat. Thus, the volume of luggage is not less than that of gasoline models (between 391 and 1069 liters). One advantage of the hybrid system is the low weight – only 30 pounds.

How it works

As for the operating principle of the hybrid "Renault Clio" in this case, it will turn off every time in electricity, using electricity for low speed traffic, for example, when crawling in a traffic jam.

The gasoline engine will be used at constant speed. At times when the throttle is not depressed and the car is in stop mode, the traditional engine will not run and the electric motor will generate a current and will also be used for the engine brake. With a smooth deceleration, the brakes will practically not be used, and this will be the resistance of the electric motor.

When the driver suddenly encounters the accelerator pedal, both the gasoline engine and the electric drive will operate at the same time to ensure good momentum. What will be the total power of the system so far is not reported. There is also no data on fuel dynamics and fuel consumption since no measurements were taken.

The dynamics of the hybrid "Renault Clio" are expected to be close to that of the most powerful gasoline engine (1.3, 130 hp), which accelerates from 100 km / h in 9 seconds. The cost in urban conditions should be lower than that of diesel, ie less than 4%.

Until the launch of the hybrid Renault Clio on the market, buyers can choose between three petrol engines and two diesel engines. Interestingly, a one liter gas turbo now has 100 horses instead of 90.
