I have purchased the zeta plus strong Hybrid model recently and driven around 1500 kms. I and sharing my experience with this car. I personally like the design of this car. My car is accessories loaded which gives it a shiny look. The Interior of this car is premium. The panoramic sunroof has a dual-opening system and it opens almost end of the roof. Also, it has safety features if any object comes while closing it stops. Mileage I am getting around 26 km/l in the city. Sometimes it gives up to 34 km/l. The engine moved from petrol to electric and vice versa seamlessly.
Battery charging generator sound comes sometimes when the battery discharged to one dot. There is no lack of power and the car picks up as you press the accelerator. The only negative is the back seat height space. If you are above 6 feet then you will have less headroom.
