Now a days there are three types of engine cars. Petrol/Diesel, Hybrid and EV. Which is reliable and give long life services and what is the hybrid battery life and EV battery life.

These days, cars are built to be very reliable irrespective of the powertrain and reliability also varies from manufacturer to model wise too. Speaking generally, a modern diesel engine is very reliable, however its long term future is uncertain with all the negativity around the fuel and its environmental impact. EVs are also reliable given that there are far fewer moving parts, battery life too is long and most brands now offer warranties in excess of 7 years to even lifetime (15 years) warranty. However in the long run an EVs resale value is yet unknown. Thus looking at reliability, and a long term service life a petrol is a safe bet. The engine is reliable and easy to service with much less complexity than a hybrid.

The choice between a diesel and a petrol really comes down to how much you drive and how long you intend to keep the car. If you drive a lot and will put many miles on your car then a diesel makes sense as only then would you recover the extra initial investment. Between the Kia Seltos and the Tata Sierra it really comes down to your specific requirements which we don't have. However if you are going for a diesel, the Kia would be better as the diesel engine is more refined and delivers a strong performance too. If it is petrol you are looking at then you can consider the Sierra but the turbo direct injection engine only. The naturally aspirated unit is under powered and lacks a lot in performance.

Looking at your requirements we would recommend the Skoda Kylaq. The automatic transmission is a torque convertor unit which is smoother than a dual clutch autobox (which is what the Tata Nexon has). You will appreciate this since you drive daily in heavy stop-go traffic. The Kylaq is also very safe with many safety features and it secured a 5-star rating in the BNCAP tests. Skoda dealers do not have a legacy of great service however Skoda has made significant improvements in service standards.

Happy birthday! And if you like the Volvo XC60, we recommend you go for it. It is, as you said, the most understated of the lot, and a less common sight on our roads, which makes it a little bit more special. Both the interior and exterior design aren't too over the top, and with the recent update in August 2025, its tech is now on par with the rest too. An underrated feature is the 1,410W Bowers & Wilkins audio system, which is possibly the best you'll find in this segment. It's an excellent highway cruiser with superb refinement at speed, and though not the most exciting to drive, it is very relaxing. Cost of ownership is on par with Mercedes GLC 300 and the Audi Q5, the only caveat being a slightly smaller service network, although Volvo is present in most big cities. For a heart patient, more so than the body style, its a safe, smooth, comfortable and predictable driving experience that is beneficial, and with its refined and relaxed demeanour, the Volvo XC60 should be ideal for you.
