I have driven this G-hybrid car (insta blue) around 600 km . Of which, 300 km was on highways. I was pleasantly surprised that the mileage touched 31 km/l when driven at 80 km/hr. In the city, I obtained around 20 km/litre. The car is extremely comfortable, has all the features I wanted, is very spacious, refined engine, a quiet cabin, the steering is very responsive, and the gear changing is smooth. The hybrid works magically and make it highly fuel-efficient, which is noticeable at traffic signals. The hybrid does come into effect in highways also when sudden acceleration is required. I wish there was a cruise control and 4 more airbags for the rear passengers. The boot space is ample for a family of 3-4. The buying experience was marvelous. The car was delivered within 4 days of booking it. The colour of the car is Insta-blue and it did attract the attention of many passer-byers. It's a lovely car and has great mileage. Probably the best hatchback in this segment.
