New L-certified Lexus IS 350 (2014) owner here. I drive relatively conservatively here in Houston (stop and go traffic w/ some freeway) in a mix of Eco & Normal mode yet the middle info cluster shows 14.7 MPG since refuel. That has me concerned as it's below what Lexus quotes for city driving.

I'm curious - what MPG do you all see on average?

To be honest, that's pretty low. I'm consistently driving aggressively and get between 18-19 mpg. I've gone through two sets of brake pads before 25k cause of my lead foot. I'd take it to the dealer for assessment.

2014 IS 250 ~27.5mpg combined city and highway. pretty impressive for the 250's 2.5L V6. I do drive pretty judiciously, though.

2014 IS250: My instrument cluster usually displays around 26-27mpg average over the course of a full tank but my Fuelly App shows a calculated 24.4MPG average since I bought the car 2934 miles ago. I drive around 75% highway.

I get 22 mpg combined (mostly highway) and best I got was 26 mpg combined. The car is actually good at highway, but it's city fuel consumption is terrifying!, but again I have a 1.6T Hyundai for city driving.

2014 IS350 Fsport AWD here and I average 17-19. Mostly city driving. Never in ECO!

I drive my 2016 IS350 F Sport on the spirited to aggressive side. Usually in mixed driving, I see somewhere around 18-19, but if it was 100% city, I could see getting closer to 16-17.

For what its worth, I've tracked every fill up with Fuelly. You can check it out if interested here: http://www.fuelly.com/car/lexus/is35...lexduke/418471

Do you have an AWD or RWD model? The 8-speed makes a big difference in fuel economy.

FWIW I have an IS 300 and get about 18-19 MPG, mostly city driving (my commute now doesn't even involve a freeway). Hoping it'll get better once it warms up.

This is the problem with city driving - it is poorly defined, there are vastly different city drivings.
Take her on a flat highway, no traffic, at steady 60 mph you should see 35+ MPG if you are in top gear.
Even at 80 mph I see over 30 MPG.

2014 IS350: I drive like an a-hole and get 17.8. Mostly a mix of city/highway everyday.

It's smiles per mile for me. That's why I bought the 350.

premier3IS
