AC on:
In Traffic (45+)
No Traffic (40)

Wow, you are not smart are you? You sound like the troll.
Also it seems you dont know the different for mpg and europes version of mpg. You also mix up your commas and periods.
I tried everything. Those that get 40+ mpg are driving highways with no traffic, no stopping, and at a constant speed on flat land.
That is not normal for drivers to get that.
If you are going to drive your CT on the interstates in the right lane going 65mph like a long haul truck driver then you can get great mileage.
And as I said, getting that mileage is independent of the hybrid system. The gas engine by itself is what gets you the good mileage. The hybrid system is just a gimmick.

I have done a enough testing to say that the mileage the mfg states is lie.
MPG: 43 city / 40 highway
Yes, saying 40 mpg on the highway is at the very upper edge of normal driving, but the city at 43 is just not possible. If you drive through down town in a big city every day, you will never reach that mileage.

I would say the more accurate mileage would be 32 city / 38 highway. If they want to add a note stating it is possible to get 40 to 52 mpg on special certain conditions then they can, but that is not normal.

If you drive short 15 minute trips on an 70 mph interstate then you will only get 28 to 32 mpg.
You can complain to Toyota if you dont like that.

r81984, your experience is uniquely yours and obviously not average. The numbers don't lie. Just look at the fuelly.com stats, over 400 vehicles with about 5.75 million miles tracked and the average mpg is a solid 42. The Lexus EPA numbers are spot on. To believe otherwise based only on your limited experience is just silly.


The numbers don't lie.

What comes to mpg, there might be some truth in that. But how many would buy these things with 73 kW gasoline engine only, 0-60 15 seconds and so on. And then there would be no regen braking etc.

You're the only one getting this kind of mpgs. So:
Option 1.- We are all liars and this is a giant conspiracy
Option 2.- You're not driving under normal conditions (bad driver? broken hybrid system? going uphill at 80mph for 15minutes?)

The hybrid system actually helps ALOT when driving at less than ~45mph. I think fuel consumption would be 50% worse at city speeds without the hybrid battery. Would be interesting if someone could test it ^^

These cars get better MPG in the city than highway. I get 40+ MPG in city driving and in traffic that's cause the gas engine shuts off most of the time when ur rolling under 45 MPH and to a stop and if u go easy on the throttle u can even roll with only the electric motor. In traffic u can't go faster than 45 MPH most of the time anyway. When u drive at 70+ MPH yes it drops to under 40 MPG that's cause ur running the gas engine all the time.

My GS gains more MPG at highway speeds but still nowhere near the CT's MPG. 16 vs 45 city and 25 vs 38 highway. So yes the hybrid system helps but only when driving slow.

r81984

They hybrid systems does very little.
You are lying, but there is no conspiracy except in your head.

I kept testing the car and found more specific conditions to give you what mileage.
30 or less = can run EV only, without hard acceleration, there are some cases up to 50 mph were you can run EV only to maintain.
30 or less = 28 mpg on gas, you can speed up quickly and coast to increase this, but not by much.
30 to 40 mph = 28 to 32 mpg
45 mph to 75 mph = 50 to 65 mpg only on flat land, no acceleration.
45 to 75 mph = around 28 to 38 mpg when having to accelerate or drive on hilly land.
75 mph to 85 mph = 35 to 38 mpg, but lower on hills or when accelerating

These are the facts.
If you drive all city, your mileage will be in the low 30s.
If you drive with lots of stops or lights then you will be in the low 30s.
If you drive with lots of accelerations due to traffic then you will be in the low 30s.

If you drive on flat land for a long time, can keep a constant speed, no stopping, no acceleration, then it is possible to get above 50 mpg. This would be very, very hard to accomplish in many cities.
Even houston with perfectly flat land has arbitrary hills on its interstate for no reason so it is hard to achieve 50 mpg for longer than a few hundred yards.

The normal mixed driver will get 28 to 38 mpg. (with reaching on the 38 mpg if they drive on long flat roads without stopping for some short periods of time). City drivers and traffic jam drivers will get 28 to 32 mpg.
The long haul drivers going through very flat roads like I55 in missouri or the turnpike in OK can get in the 50 mpg range if they keep their speed below 75 mph.
This mileage is achieved without the hybrid system and only with the gas engine.

I can see how the MFG got the 40 mpg highway rating, but they clearly lied about a 42 mpg city rating.
The car gets worse mileage in the city than the highway and there is no room for argument.
There is no way to get 42 mpg stopping at every block for a stoplight or stop sign and driving 20 to 30 mph. It is impossible.

Do you realize that most people are actually getting 40-50MPGs with normal conditions? Do you think that the data posted by StillLine was conducted by a conspiracy of liars wanting to prove you wrong?
I live in Lausanne. It's certainly not a very big city but there's still a good amount of traffic and it's anything but flat. It goes uphill and downhill like crazy. Everything here in Switzerland is like that... Even our motorway is not flat at all and people usually cruise at 80MPH.
And I still get from 5l/100(~47mpg) to 6l/100(~40mpg). Even my wheels are not that good for fuel economy as they're not small (17x7.5 with 225/45 R17 tyres).

As for the hybrid system being a gimmick... I'm sorry but that's BS. I don't know how you can even think that When driving at city speeds, I drive ALOT in electric mode only and that makes a huge difference in fuel consumption. There is NO car in this category that is able to get this kind of MPGs with a gasoline engine.

Maybe there's something wrong with your car. EGR problem, MAF, 12V battery or something like that..

Raidin

Those hills are overpasses, they allow traffic in the service road/frontage road/feeder road to move across the highway by going underneath while highway traffic keeps going uninterrupted above.

Unless you meant something else...

sonnyhood

this was just after fill, after 50km driving to work it increased to 3.5l/100km

So 3.5 L/100km = 67.2 mpg
3.1 l/100km = 75 mpg.

its a 2011 CT F Sport and just came back from Lexus warranty service to replace a head gasket and timing crank seal.
The car drives so much better, much more power and look at the mileage.
I had to send a pic as proof.
before warranty it was doing about 4.5-5L/100

I always fill up when the gauge get to 1/2. I make sure that I always get NON-ethanol gas. Much better gas mileage. I have been getting mid 40 mpg.

E46CT

Very heavy stop and go, racing stop light to stop light w/ AC, if I do that the ENTIRE tank without highway, i'll get about 36-37 CALCULATED.

Though on a long distance highway trip, AC, radio playing with two amps, wipers going, I got EXACTLY 50.0 MPG (about 250 miles round trip all highway)

I find MY realistic MPG for this car to be about 37/50 while the EPA has 43/40. I can do 50 all day long on any highway trip. All day long. Repeatable. 72 mph or so avg speed. One time during a similar trip, but TRYING to hypermile, I got about 55 mpg indicated. But 50 is no sweat driving normal.

E46CT

I know this quote is three years old... but that's pretty interesting. I wonder if there's any downside to topping the tank off. I never tried looking into it but our tank is on the small side and a little extra range (say 1 gallon extra instead of your 3) would be awesome if it doesn't hurt anything..

And yes the theoretical range on our cars would be best at full 50 mpg (about what our cars can do on highway) x the # of gallons in the tank. I always get about 50-52.5 on highway. 55 if i REALLY try and don't exceed like 60-65

My car is lowered too so theoretically that should help. an inch lower on all four corners is a total of four inches of tire the wind doesn't have to slice through. So at a 7 inch wide tire x 1 inch that's 28 square inches of rubber. And that rubber is rotating further adding resistance (probably)
