i get 375-345 miles with 60-70% city 40-30% highway

 

Very similar results to most of you here.

IS350 AWD getting approx 480KM per tank. But in the dead of winter right now in Toronto, it's definitely closer to 420-440KM per tank.

This is driving in Eco mode 99% of the time, and a hwy/city split of 90/10.

I guess I can't complain since the engine is quite the gem at balancing comfort (quiet, smooth, and linear power) and performance. Although, I wish it had a turbo to remain competitive with other automakers in fuel efficiency. The suggested fuel economy figures on Lexus.ca is a joke. (7.7/11.0 hwy/city split for those too lazy to look)

 

I have a 2014 IS250 and get about 375-400 miles. 40-50% highway. Averaging 26.5 mpg

 

wow, that's pretty good!
2015 IS250 here. I get around 290 miles with 35% highway, 65% city

 

Wow, 220 miles per tank? This might be the first time I'm not regretting my 250 over a 350. I do mostly highway driving; however, I-95 is absolute hell every evening with the stop and go traffic. Still, when i fill up, my range is showing about 360-380. In the summer, when AC/Heating isnt being used, i was in the 390s. Got about 12,500 miles on my car, for reference.

 

About 450 km in winter driving conditions with some remote start idling... About a 70/30 City:Highway ratio.

 

After the new 5-stage fuel efficiency testing methods were established for 2015 models by Natural Resources Canada, the ratings are 9.1/12.6 (L/100 km) Highway/City. With a 66L fuel capacity, we should be getting ~524km per tank until ideal City conditions.

Having said that, I can't believe Lexus Canada is still advertising the 2014 ratings on their website with a small disclaimer, "2015 models do not have higher fuel consumption vs 2014 models, only the methodology for determining the fuel consumption ratings of 2015 has changed to better approximate typical driving conditions/behaviours." This disclaimer does not give them the right to hide the actual rating in a long list of specs elsewhere.

345 this morning.

 

For some reason these numbers feel very high. I have an F sport intake and exhaust and I feel like I'm getting about 200 per gas tank ( I will measure on my next fill), should this increase the gas consumption? Or do I have an issue with my car?

 

I just filled up my tank and it states that the range is 260 miles. Is this thread telling us that the range is wrong? Or is it different for me since I have a 350 RWD? If some are getting more than this I have a serious issue.

 

Where in CA are you located? Winter gas? I'm in the bay and get ~310 for range and its usually fairly accurate in my experience
