I currently drive a 2020 Tata Tiago petrol and have clocked nearly 1 lakh kilometres in five years. I’m planning a replacement now as my usage remains high — around 1,800 to 2,000 km every month. My budget is between ₹10–12 lakh. I’m wondering whether shifting to a diesel car makes sense at this point, or if I should continue with petrol. Also, which model would suit my requirements best?Asked By– RameshCarBikeGPT Says: With the kind of distance you cover every month, moving to a diesel-powered compact SUV is a logical step. The stronger torque delivery and lower running costs will benefit you over long-term ownership.A suitable option for your upgrade would be the Maruti Suzuki Brezza (diesel variant). The engine offers solid mid-range performance, making it effortless to cruise on highways while still being frugal in city traffic. Diesel engines also tend to handle long-distance usage better, which aligns well with your driving pattern.Within your budget, you could consider the mid-level variant that offers a well-rounded feature set — including automatic climate control, a reverse camera with sensors, a larger cargo area, and a more premium cabin experience compared to your Tiago. The gearbox is easy to work with and suits both daily commuting and long trips.Based on your mileage and upgrade expectations, a diesel compact SUV like the Brezza provides better long-term value and a more effortless driving experience — especially on highways. If your usage ever drops dramatically in the future, petrol may make sense, but at your current running levels, diesel remains the practical choice
