Let’s all agree that switching to electric cars overnight isn’t going to be easy. There has to be an intermediate solution that reduces our dependency on fossil fuels while preparing us for the impending electric future. Maruti Suzuki trusts it’s got the right tool for the job in the form of their HEV technology. HEV stands for Hybrid Electric Vehicle, and it is exactly what the name suggests. Like the SHVS system used on Marutis in India, Suzuki too uses alike mild-hybrid system in Japan, however the HEV system is a strong hybrid system proficient of powering the cars on electric power alone. As you’d expect, a hybrid-electric vehicle relies on two power sources (fuel + electricity) to run. Suzuki’s HEV tech includes of 3 units – the engine, an integrated starter generator (ISG) and crucially a motor generator unit (MGU). The one on display at the Auto Expo features Suzuki’s global 1.2-litre Dualjet motor paired with a 10kW motor generator. This setup already does duty below the cover of the Suzuki Solio (think of it as Japan’s WagonR) and the Suzuki Swift in Japan.

Under low or steady load, the system switches to pure electric power. The batteries supply power to the electric motor that in-turn drives the front wheels through an AMT gearbox. On pure electric mode, the Solio hatchback can run for 2 kilometres. Suzuki also says that the hatchback can drive in pure EV mode at 40kmph for 3 minutes.
Once the batteries run out of juice, the system switches over to good-ol’ gasoline. In the meantime, the system will focus on refeeding the arrays while you coast by using reformative braking. Also, when you decide to give it the beans, the electric motor assists the petrol engine, thereby giving you some more power (and torque) to play with. In terms of price, the Solio with the HEV system is about Rs.40, 000 more than the mild-hybrid armed version.
