Car performance and fuel efficiency is good. Pickup in traffic or highway is upto the mark, thought cars shows bit pickup lag when it's full on luggage and all seats occupied.
I drove it to 600 km at a stretch and on 7000 ft high mountain hairpin bends. It didn't disappoint me both the cases.
Ride quality is smooth and easy on the driver.
The only downside is built quality. The body frame of the car is unlike its predecessors. Maruti should not have compromised on it.
Milage in the city is (15-16)
Milage on the highway is (18-20) depends on your average speed.
So in a nutshell, except strength and built quality, i like everything about my car
