I have a budget of around ₹10-12 lakh and need decent fuel efficiency, as I’m not confident about petrol mileage after fuel blending. My running is on the lower side. Should I consider a Sonet diesel or a Fronx petrol? I would prefer an automatic option with features like proper hill hold control. Please advise.

If you want efficiency, the Kia Sonet diesel is the one to go for. Beyond the cost advantage of running a diesel, the Sonet diesel is actually nicer to drive than the Maruti-Suzuki Fronx petrol. 

The Sonet 1.5 diesel offers better performance and works well with the 6-speed automatic transmission. The Fronx is, of course, cheaper, but if you have the budget and want a car with low running costs and want an alternative to petrol, then the Sonet diesel is for you.
