I have an Audi A6 C7 2019 S Line, which is lightly driven with 14,000 km and has a company record. Since the vehicle is 7 years old, should I switch to an Audi A4?

Keep the A6. With only 14,000 km and a full company service record, it is barely used, and you already own the bigger, comfier car. An A4 is a size down, so you will notice a tighter cabin. At seven years, the smart move is a preventive refresh - new tyres, battery, fluids and rubber bits. That bill will be far lower than the money you will lose by selling the A6 and buying an A4.

Switch only if your daily use is mostly tight-city driving and you want an easier-to-park car with a fresh warranty and newer screens. In that case, the A4 petrol is smooth and light to drive, and it will sip a bit less fuel. Just do not expect it to feel as special as your A6.

I will suggest don’t even think of replacing your car unless government fixes the fuel blending. By the way I also own 2022 model petrol A6 Tech Pack..and had similar usage and thought tto replace

Hi Team, I am from Bangalore, and I am planning to buy Mahindra Thar Roxx AX7L Diesel AT 4x4 in October 2026, hoping to get festive offers. My annual running is around 12,000 km, with 70% of it on highways. If I use my car only on weekends in the city and occasionally (once every two months) for long highway drives, will that be enough to avoid DPF-related issues? With the upcoming Isobutanol fuel blending, do I need to be concerned? Are Mahindra diesel cars compliant with this fuel?

With 12,000km a year and 70% highway driving, you are actually the ideal diesel owner. The Thar Roxx AX7L Diesel AT 4x4 is a great choice for your usage pattern, and you should not be worried about DPF issues. The DPF system needs sustained higher exhaust temperatures to regenerate, and your regular highway runs will take care of that naturally. Even if you are only using the car on weekends in the city, as long as you are doing occasional long highway drives, the system will regenerate as intended. The real DPF problems tend to occur with cars that are used exclusively for short, low-speed city trips with no highway running.On the isobutanol front, there is nothing to worry about. Isobutanol is being considered as a diesel blend, but it is not a major policy direction like E20 petrol. Mahindra diesel engines are designed to handle the fuel blends available in the market, and there is no evidence to suggest that isobutanol blends will cause any issues. The bigger concern with diesel ownership is always usage pattern, not fuel blends.The Thar Roxx is a very capable and enjoyable SUV, but it is worth being aware of its limitations. It is not the most practical family car, and the ride can be a bit firm on broken roads. But for your usage pattern, it is a solid choice. If you are looking for a more practical alternative with similar diesel capability, the Mahindra XUV 7XO Diesel AT is worth considering. It offers a more comfortable ride, better practicality and the same strong diesel engine. But if you want the Thar Roxx for its character and off-road capability, your usage pattern supports that decision.
