In the universe of alternative cars we find several options and one of them are the electric ones with extended autonomy , whose electric motor receives energy from both a battery and a combustion propeller that acts as a generator. This is the case of this Tesla Model 3 with last name HyperHybrid developed by the Austrian engineering company Obrist Powertrain , which promises an autonomy close to 1,000 kilometers .
The objective of this hybrid train patented by this company is to offer an electric car alternative for those countries where the charging infrastructure of electric vehicles is still deficient , for example in Austria according to Electromaps the charging points barely exceed 2,000, as well as for those consumers who do not have their own garage and therefore a plug in their homes.
Why extended autonomy electric cars can have a future in Europe
And that’s how this Tesla Model 3 HyperHybrid was born, still in the prototype phase and in the process of approval, which are waiting to start marketing in 2023. In short, the Tesla model becomes an extended-range electrician that replicates the concept of other models already existing in the market, although a very small offer in Europe as well as those of hydrogen, such as the BMW i3 REX or Karma Revero.
Turn electric into hybrids to help democratize electromobility
In this way, Obrist Powertrain incorporates in the Tesla Model 3 a small gasoline engine of two cylinders and 1.0 liter that yields 54 hp , which they call ‘Zero Vibration Engine‘. It is located in the small front trunk of the Californian model and supplies energy to its electric motor.
The Model 3 based on this company is the Standard Autonomy, which has a single electric motor associated with its rear train and a 50 kWh battery capacity. The Obrist Powertrain system also replaces the electric car battery with a smaller, cheaper, 17.3 kWh and 18,650 cells, which reduces the total weight of the car, because for the scale by 98 kilos compared to 478 kilos of the battery that carries this series version.
Thus, this curious Tesla Model 3 allows to improve the efficiency, in addition to autonomy , which is estimated according to Obrist Powertrain in 1,000 total kilometers . This variant in question, in its production version, ranges between 190 and 395 real kilometers depending on the temperature and cycle, whether urban, extra-urban or mixed.
In the Tesla Model 3 HyperHybrid the thermal propeller comes into operation at speeds above 65 km / h and announces very low consumption and emission figures, standing at about 1.42 l / 100 km in mixed cycle (NDEC), while the emissions do the same in 33 g / km of CO₂.
And while Obrist Powertrain is testing its technology in a Model 3, as well as in a BMW i3, they claim that its system can be integrated into various types of cars , from urban to saloons or SUVs, due to the small size of the components it uses (both the battery and the combustion generator). In fact, his first prototype was a Geely EC7 .
In the same way, this company also has another version of greater power of its system, which reaches 116 hp and uses two combustion generators instead of one . According to Edison Media , Obrist Powertrain is already in the process of obtaining the production licenses for his system and they hope to start marketing it within three years.
The hydrogen car is the future in Japan, but in Europe it won’t be so easy
Electric cars of extended autonomy are, like those of fuel cells, an interesting alternative for those drivers who do not have their own garage. However, European manufacturers are betting more on pure electric or plug-in hybrids, than if they require an outlet at home.
Among the electrified models that will arrive on the market this 2020 we only find three of extended autonomy and all of them are Japanese: the new Honda Jazz e: HEV , a variant of the first electric Mazda, the MX-30 , and the Nissan Qashqai e-Power .
