I am confused between the BMW X3 30 and the X3 20d. My first concern is about the long-term reliability of E20 petrol and its impact on critical engine components, as well as future compatibility with higher ethanol blends like E30. Diesel, on the other hand, is ethanol-free. Secondly, both variants produce the same 400 Nm of torque, so does the difference between 197 hp (diesel) and 258 hp (petrol) make a significant real-world impact? Which variant would be the smarter choice for hassle-free maintenance, good mileage, and ownership over the next 5-7 years?

I have mainly city drive in bumper to bumper traffic in Bengaluru or Kolkata. Long highway drive include Bengaluru to Kolkata and back twice a year. Also there are some vacation trips to hilly areas of western ghats like ooty and kodaikanal. I might plan for vacation drives to Pune or Rajasthan or Tamil Nadu in days to come back that would be once in 3-4 months max.
