Gas prices are getting ridiculous. I'm lucky though NJ has some of the lowest prices around. V-Power cost me $3.19/gallon on Monday.

For the cold weather folks, have you turned off eco mode yet? I decided to do it tonight so I could get a little more heat. Temps have been in the 20s-30s the past few days. I'll take the hit on gas mileage to keep the toes toasty

I've been turning it off at start-up to warm up the cabin a bit faster. Headed to single digits tonight. After a year of ownership, the best I've done was a tank with 29.1 MPG average. No hitting 30 for me B-(

After the 1st 2 months of ownership and 1200 miles, my 450h averages 27 MPG on the highway, and 23 MPG in-town. The in-town are short trips of < 10 miles and temps from 30-45 degrees, and not in ECO mode. Assume MPG will pick up after break-in, and will try ECO mode setting when it warms up in the Spring.

I just did a return trip of 500 kms each way. With only 1450 kms on my RX 450h, I'm averaging 10.5 L/100 kms. I consider this quite good considering the below freezing temperatures.

If my conversion is correct, that is 62.13 miles divided by 2.77 gallons or 22.4 MPG (for the folks like me who do not have a clue about the metric measures).

22.4 mpg is pretty good for the RX in sub freezing temperatures I think especially since my RX is so new. How many miles or kms. until the engine is considered broken in, any idea?

on a hybrid, "broken" in is much longer than on a regular car so its more like7 thousand miles. But expect improvements as early as 3K and 5K

I'm running 26+ in 20F weather. Started playing with the EV mode when speeds allow -- very easy to kick into regular run mode. But it does stretch MPG. Not sure that I really saw a burn in during the first 5K miles, but I went from warm to cool weather during that time.

I have 19,000 and change on my 2010 RX450h now and some of my best mileage was in the 1st few thousand when I drove with an extra light foot. In fact most of my 1st few tanks averaged 30 or better mpg.

Over the past year I've played a little too much with the 'available' power of both gas and electric power plants and my mileage over the last 4 months is down to 28.8 mpg. I have discovered short trips under 5 miles (especially when it's cold) or murder on good mileage but even when it's cold if my trips or 10 miles or longer and I watch my acceleration I can still get around 30 mpg.

You can get exceptional mileage right out of the box but not if your trips are primarily short ones or you accelerate to hard. One thing that did supprise me was slow stop and go on the expressway when you're able to keep the 'ICE' off for long periods gives phenomenal mileage where as a conventional gas only car gives awful mileage.

yep...they dont write that in the brochures

hills, cold, short trips and even the highway are not biased towards hybrid driving.

Try driving it like you know for a fact it will be two more weeks before 'your ration card' will let you buy anymore gas anywhere.

Folks if there were ration cards and we all drove that way, our (h) models would never be under 30mpg.

I wish I could drive that way! However (at least with my car), after stopping for a red light, accelerating to 45+ mph takes forever if I try to keep the tach in the "green zone" (with folks honking and glaring at me as they change lanes to pass). When I have a chance, I'll find a back country road, and measure my 0-45 MPH times when keeping the car at it's max green limit in ECO mode. Might be an interesting comparison for some of us! After 6,000 mi, I'm averaging 25.5-27 mpg (75/25 city/hwy driving).

Silly newbie H question for you, I have just over 1500 gentle miles on a new 450h, is it too soon to 'peg' the power meter (WOT run) ? I'm dying to find out what the engine sounds like at WOT and feel the torque from the electric motors in conjunction w/the CVT . . .

It's not something you need to do on a regular basis but when you're on a two lane country road behind a farmer, that's a good time to feel/hear the passing performance of just under 300hp. You won't forget it for awhile .

Just make sure you've warmed it up good, then hang on .

Youve waited this long, I would wait for at least a thousand more miles before you floor it
