yeah I agree with you on sticking to MPG.
Its early to say, but I get 18.7MPG after 200 miles on it with my TX350. I think I can get it up to 21-22mpg.

 

I have almost squeezed 24mpg out of my TX 350 on the highway in cruise control around 70mph. you should be able to get more than that if you stick to 65mph or so.

 

I'm getting 14mpg this is crazy I just got tx500 hybrid f spot 2weeks ago

 

you'll need to do at least 5 tanks worth to get any accurate reading. it's brand new and you are probably having fun with it. how many miles are on it?

 

From my experience, whether or not a car is "broken in" only equates to a 1-2 MPG difference.

In my case, living in San Diego, which is hilly, I generally get approx. 10% less than the EPA rating for a vehicle. When I am on a road trip I generally hit the EPA rating.

For those that are experiencing 20-30% less, I can't understand what is going on there. Maybe a combination of lead foot, hilly terrain, tire pressure, windows open, A/C on, etc.

Maybe check the engine air filter to ensure it is clean and installed correctly? Other than that, maybe Lexus has a software update that addresses the engine performance assuming that the poor MPG has been manually and accurately calculated.

 

Our TX350 has approached 20 mpg after 700 mi in normal mode.

 

that's not too bad. is that combined or strictly highway?

 

Combined. We drive about 70% hwy 30% city

 

Finally got 1200 miles on our TX350, and computer says I'm getting 21mpg driving combine hwy & city running BP premium (93).
Been slowly improving, but notice it uses a little oil so far about 1/3qt total.

 

it is pretty standard for a brand new car with rings seating and other things breaking in to use a bit of oil. most cars these days consume oil all the time and if you read the manual (any car) the in spec oil consumption numbers are insane. most MFGs accept like 1 quart per 5000 miles as normal.

 

So at about 300 Miles on the ODO my milleage had creeped up to 22.4 mpg. I reset or cleared the MPG value and drove my TX500h like my CT 200h, and achieved 28 mpg over 120 miles or so.

I had seen the early reviews on this car and how no one came close to the EPA rating...but I'm certain no reviewer had a CT200h. Steady Eddy and no hurry driving is the key.

I had lots of minutes in the car at idle learning the menus and switches and such so once I was clear of the learning curve cleared the data and started new. I haven't checked by filling the tank and recording the miles traveled yet....will do that on my third tank.

 

In my experience, all the Toyota/Lexus "power" hybrids have been deeply disappointing as far as MPG vs rating. Tundra and Sequoia with iForceMax were barely better than the V8 of prior gen. Saw similar on the Grand Highlander HybridMax, I got about 23 MPG over the course of the week with fairly light driving (rated 27 combined). But I was still happy with that relative to the nice level of power as well as traditional albeit 6-speed automatic vs something like the eCVTs on the normal hybrids.

In a TX550h+ this week. First longer drive with some highway and A/C on blast we netted about 35 miles electric vs stated 33 mile range.

 

I bought my. TX500h L Certified with 1530 miles on it. It’s got about 3500 miles on it now a bit over a month later. The onboard computer is reporting about 24 MPG.

 

I think a lot of this has to do with car configuration as well. if you were a MFG you would provide models to the EPA with the base, smallest wheel package possible. a TX with an 18 or 20 inch wheel/tire combo will always get better MPG than one with the 22s. it's physics. I can tell you the 22s with all seasons are HEAVY moving them around and my 18" snow tires on aftermarket wheels are much much lighter....

this is something people have been doing in the motorsports industry for a long time to save on rotating mass and unsprung weight.

 

What I know is hybrid is good when you drive in city alot. Maximize the electric motor as much as possible, which means go light on the pedal. If I nuke the pedal, of course MPG will be poor. I drive ky 350 lightly, cruising 65-70 on highway, and sometimes I get above 30, average 26-27.
