What actual fuel consumption for IS350 ? Boring I know !

Recommended Posts

Morning all,

I am considering buying a GSE31R IS350 luxury or sports luxury.  I've heard they are not too good on fuel.

I've searched the forum etc but was hoping for a little more precise info.

I was just wondering if I could get feedback from people on the actual fuel consumption for suburban only (not daily commuting into CBD) and highway only assuming driven quite conservatively (yes, perhaps a bit of a waste!)

Thank you for your feedback

My 2012 IS350 was normally getting 15.8-16 L per 100kms this was 100% inner city Sydney driving with no highways. Max speed about 70kms and heaps on traffic..

Hi my 2010 is350 gets a consistent 7.2l/100km doing 110 without cruise control from Brisbane to Gold Coast. If I set it on cruise control to about 95-100kph, I get about 6.9 on the same trip. I can't tell you what the suburban is, but my avg consumption combining city/highway is about 12.8l/100km. This is driving the car pretty easy.

That's pretty bad.  I wonder how it would go towing approx 1000kg caravan, as if I owned it rather than stole it.

I dont think it would get anywhere near that. I was just quoting worse case , racetrack style :)

As you can see from the other above posts generally on cruising they are pretty good.

That's good, just need to find a towbar solution.  I am looking for a decent sedan which can also do periodic modest towing duties, so I was hoping the IS350 might do the job.

Thanks for the towbar suggestion bazzle, I'm in Brisbane but will see what insights they may have.

Ummm, 350s aren't meant to be a tow car. My user's manual doesn't have it as an option whereas the 250 is. I figure it's got something to do with the trans tune; you may wreck the trans. I could be wrong - haven't looked that far into it.

Hi Kelshouse,

I own a 2019 IS 350 F sport and get around 9 l/100kms on average. I live in inner Sydney and so I don’t use it as a commuter hack, mostly to visit relos out at Penrith and down the south coast where I love the overtaking power. Since I don’t need to commute I’m not worried about fuel economy. In reality this beautiful car is wasted on me as I don’t use a fraction of its power and handling potential but it’s sooo luxurious, punchy and fun to drive (do I sound like a commercial for Lexus? Sorry!). I wouldn’t think of towing with my car - that’s what SUVs are for. 
Hope my rant hasn’t put you to sleep. 🙂
