We are looking for midsize luxury SUV and have it narrowed down to Infiniti Q50 and the Lexus RX350. We really loved the Infiniti 50 Essential that we drove today, but when we got home realized that it needed premium gas, which makes each fill up about $10 more. We do put a lot of miles on the vehicle so this might be a deal breaker.

Would like to know the communities feedback on the true mileage this car gives... It showed the QX50 would give about 27 mpg average.

Thanks

Would assume that the Q50 would be a much funner drive!

25-27 MPG is about right for the Q50, but, I believe you mean the QX50 SUV and not the Q50 sedan.
