Thinking About Sustainability, The German Automaker BMW Will Include In Its Electric Car BMW i3 An Ethanol-Powered Range Extender

The BMW i3, an electric car that has been sold in the country since 2014, will soon receive updates. BMW announced that it is testing a unit of the model that has an ethanol-powered generator. In some versions of the BMW i3, small 650 cc scooter engines powered by gasoline are used to recharge the battery that supplies energy to the electric motor.

The electric car, which currently costs R$ 304,950, with the use of ethanol, will become fully neutral in CO² emissions since the gases released by the exhaust system can be reabsorbed by sugarcane crops.

The electric generator of the BMW car is the same as the gasoline scooter engine, that is, 170 horsepower and 25.5 kgfm of torque. This two-cylinder engine that comes from BMW Motorrad scooters acts as an electricity generator but allows the electric car’s motor to function even with the batteries drained.

Even so, this does not make it a hybrid, as the small engine of the BMW i3 Rex does not drive the wheels; it only generates an extra charge for the electric car’s batteries, increasing the range by up to 60 kilometers. It is precisely this small scooter engine that can be converted to ethanol to neutralize the CO2 emissions in the BMW vehicle.

Changes Made By BMW To The Electric Car

To install the ethanol conversion, the automaker revealed that it was necessary to make some changes to the engine head and increase the compression ratio, which has also been done in cars that used gasoline engines and became flex. The development of the ethanol-powered BMW i3 was carried out by the automaker in partnership with AVL do Brasil.

The company does not yet have an official date to launch the technology in Brazil and states that there is no chance of presenting the ethanol-powered electric car in the short term, but knows that the setup is almost ready for the streets.

The electric car BMW i3, which has been on sale in Brazil for over 7 years, has an acceleration from 0 to 100 km/h in an impressive 7.3 seconds. The vehicle can reach a speed of 150 km/h and its battery allows it to achieve a range of 335 km on the WLTP cycle and 440 km with the optional range extender (using the small engine mentioned before).
