Hey guys, what the overall combined mpg on your car?

 

You can look at real-world data here: https://www.fuelly.com/car/lexus/lc500

 

Best ever 28 on a short trip. Overall average 22, but I drive with a feather foot.

 

I got up to 31mpg doing 70mph on a long trip

 

driving around in a city in a lot of slow speed (think something like manhattan/newark in terms of driving environment) and stop/go traffic i get an average of 8km/L (about 19 US MPG) as measured from the actual fuel uplift (not the onboard which overreads by about 0.5km/L so on mine is says 8.5km/L).

My buddy in his 2012 IS250 gets about 20% better fuel economy than me with the same driving conditions. So I consider the LC500 consumption very good for a car this heavy with an engine this large. With constant speed highway use at the speed limit, i easily get 1.7x the fuel economy

 

Best I’ve seen on my ‘18 was 31.1 over a 441-mile interstate haul. Local rural driving = about 25.

 

32.6MPG @ 82 MPH in Comfort mode across northern Arizona / New Mexico. 10th gear, like ~1700 RPMs.

FYI the car only uses 10th gear in Normal, Comfort and Eco. For straight highway cruising Comfort and Eco don't seem to perform any differently, so better to have it in Comfort. Eco seems to smooth the throttle inputs, so may be better in stop&go traffic.

 

~2500 mile road trip with occasional spirited driving in it = 24mpg average.
