I need more comfort and ease of driving.
Hyundai i10 is not available in India with an automatic gearbox. The car you need would be the Grand i10, which comes with a 4-speed automatic gearbox. It is actually many times better than the simple AMT unit on the Renault KWID. The gearbox on Renault KWID does not offer hill hold control, making it worse when it comes to riding on slopes and holding in heavy traffic. The creep mode is also missing from the car. Hyundai i10 uses an actual automatic gearbox with all these features and comes out to be more efficient and safe in all cases.
