I have filled my tank fully when range is near 0 about 8 times. Here is the mileage extracted from each tank:

Gallons added:

Remember our tank capacity is 17.2 gal and our rated range is 516mi city, 482 highway. This is only true if you run your car dry though.

 

That’s surprising, I purchased my RX from a certified pre-owned Lexus and they stated it ranges between 500-650 miles fuel range.

Thats disappointing if it is below 400 mile range honestly for a hybrid.

 

"They stated"? Lips moved?

 

I state that the RX hybrid will give you 1000mi+ range. Believe me, I'm smart. The range is huge. Don't fact check...

 

I average 400 miles per tank. Max was 450 miles (perfect run at 30 - 40 MPH). It drops above 70 MPH. Keep in ind the tank is smaller than the RX350.

 

If it's your first fill up, give it a few more tanks to 'learn' your driving style and the range will be more accurate for you. Previous owner may have been a hard driver, or it may have been sitting around with lots of short trips prior to you buying it, which reduces mpg and the range reported.

Fwiw, my typical range after a fill up in the summer time is around 800km (500 miles), and I usually fill up when the warning light comes on; and that's usually at 700-720 km (435 - 445 miles). But I do a lot of long easy commutes, so it helps with the mileage.

 

Unfortunately the folks at that dealer didn't even bother to do the basic math. 17.2 gal * 29 mpg (est) = 498 miles. 650 miles would be nearly 38 mpg. The real range is more like 450-525 (ish).

FWIW, I've been able to get a very consistent 31-32 mpg. I'll go 400 miles comfortably before I start thinking about filling up. The meter reads about 1/4 tank at that point, usually ~ 13 gallons go in.

I just reset all the drive data I could find to clear the prior driver as best I could, and then reset the trip computer on fill ups and just started tracking my own range based on my observed mpg - I know 400 miles is safe, I rarely look at the range anymore.

 

What is your mix of driving city vs highway?

 

Mine has settled in at 22 - 24 mpg combined. I’m not sure if I’ve mentioned this previously, but the A/C appears to drain the hybrid battery FAST & the car won’t go into EV mode, because it’s always trying to charge the dang battery up. My mileage has now flipped & is much worse in the summer vs. the winter. Has anyone else noticed this? Keep in mind, my average temperature right now is between 98 - 105 degrees (F).

 

That's to be expected actually. The batteries in our vehicles (and all the other electric cars out there) have a narrow optimum temperature range. Once you are out of that range, they don't hold as much charge and drain faster. The more extreme the temperature, the worse the batteries get.

I have noticed about a 5% drop in mileage as our temperatures climbed to 30C (86F) recently and I had to use the A/C during the day. It's roughly on par with the winter mileage, although we don't get the extreme cold in the Vancouver area.

 

Around here it may be better to describe it differently Because highway driving is often stop and go.

It's 23 miles to work. First 4 are suburb / frequent stoplights / 35 mph or so. The next 10 is rural highway, usually 40-50 mph, 5 lights. The last 9 is highway in the morning (60 mph). But coming home that 9 miles is bumper-to-bumper stop and go. The other 14 is similar to the morning.

What I've observed is the car really likes the rural highway part from an mpg perspective - that helps. 45-55 mph cruise seems to be a sweet spot, and 18 of my 46 miles are doing just that. The actual highway isn't too bad either because 60-65 isn't too bad for mpg. The bumper to bumper part is offset somewhat by a lot of electric only driving because the speeds are < 15 mph. The worst parts of the drive are the suburb parts. Stop, go 35, stop, go 35, stop.....

 

I’m looking to trade in my 2012 IS 250 for a 2020 RX450H. Just wanna know what’s the mileage on the hybrid like?
Also what is maintenance like ?

 

Here's my Canadian perspective. Maintenance is very little (oil change every 16,000 km and problems for me with brake caliper slide pin seizing with our harsh climate).

Mileage is 8 l/100 km for city driving in summer. If short trips (less than 5 km) it is much worse as it never switches to battery. Above 110km/hr on extended road trips it's 9l/100 km as the hybrid system makes little difference. In winter it drops to 10l/100 km. Hybrid is awesome in extended stop and go and below 70 km/hr.

First fillup in my 2019. 445 miles with 13.69 gallons = 32.5MPG. 50/50 mix of highway (with many long stretches of steep climbs up and down) and local drives (35-45). And I suspect that first tank of gas put in by the dealer was probably regular, so it might get even better as I put more miles on the car. Super impressed with the car.

I drove a 2012 RX450h for 65k miles before I traded up. Purchased in 7/2014, the average for those 65k miles was 27.8MPG, having gone through 5 winters with it. The trip computer in the RX hybrid is highly accurate, I could tell because I calculate every fillup manually, unlike the CT200h which is usually +2MPG over actual.
