I'm currently in a loaner 2013 CT with approximately 5,500 miles. When I got the car, the tank showed just a little under half tank. The estimated range was 24.

Well, after approximately 24 miles, it read 0. It's been 0 for over 100 miles already. I thought the range estimate was smart and constantly adjusting?

Showing 24 miles from just under half a tank is a little strange ... Although +100 mile range from 0 isn't so much. There's a reserve built into that calc and I think Lexus are still doing the Gallons/Litres reserve amount according to what their thirstier cars need. So the CT and my IS300h have about 8-9 litres in the tank when the light comes on, good for 100 miles ish up from the 50 ish in the thirstier cars. Would I trust that or just fill up ? Lol no - no point running the tank dry just to prove a point :).

Mine is more optimistic than it should be. From full it shows cruising range of 800km, but realistically it is more like 650. It always shows about 20% high until I get under 1/8 of tank, then it ignores the 10l reserve and shows a very low cruising range. It renders the whole estimate quite useless.

Yes the range calculation is broken/messed-up on your loaner, but don't worry it is just a loaner. You can use the old school tools of gas gauge and /or trip odometer. Or if you are paranoid, carry a 5 gallon fuel container. Contrary to popular FUD tales you can run out of gas in a CT200h and then put gas in an start-up again just like a regular car.

One other issue is that if the gas tank is running low, and only a few gallons are put in, it doesn't update the range indicator. Doing that a few times would really screw up any potential warning signs. In reality, when the gauge hits 0 miles, I still have 2 gallons left in the tank, which translates to nearly 100 miles. I've never run out, but I have gotten to the point where upon fillup I was a half gallon to fumes. But that's still over 20 miles. Talk about being conservative!!!
