Hello, I am looking to buy a sub-4-metre car and will be a first-time car buyer. My daily running is around 40-50 km, with a 60:40 highway-to-city usage ratio. My priorities are good fuel efficiency, low running costs, low maintenance costs, and a comfortable driving experience. I would also like to know whether it is better to buy a diesel or petrol car at the moment. I am concerned about E20 fuel compatibility issues with petrol cars and DPF-related issues with diesel cars. I am quite confused and would appreciate your advice.
Consider the Maruti Suzuki Baleno petrol. With 40-50km a day and mostly highway driving, it delivers very good real-world fuel efficiency, keeps service bills low, and rides comfortably over bad patches. If you prefer a slightly higher seating position, then the Fronx is a good choice too. Both are E20-ready, and Maruti has done a good job calibrating its engines to run on E20 fuel, so efficiency remains competitive. When higher ethanol blends eventually roll out, you can still expect some drop in fuel economy, though most modern cars are already material-compatible with ethanol blends beyond E20.
For your usage, petrol makes more sense. However, if you expect your running to increase significantly, particularly on the highway, then the Kia Sonet diesel or Hyundai Venue diesel would be worth considering.
