Wow.. I am impressed with the gas mileage (28.1 MPG!)
Ok.. memorial day weekend, Vegas, family trip, ~600 miles (roundtrip).
We had to take two cars (LS460 + RX400H), guess who won.
Temperature ~80-100 degrees (~85 degress most of the time)
98% highway/ 2% city, no traffic 75~80mph normal speed
A/C on LOW, Chevron Supreme 91
Here are the stats.
LS460 4250lb, 4 Adults, ~40lbs of luggage, 38 PSI tire, 28.1 MPG
RX400H 4100lb, 2 Adults, -20lbs of luggage, 34 PSI tire, 26.2 MPG
unbelievable, the LS had about ~400 more pounds of weight and still managed to get a better mileage than our hybrid. More power and room..
Let's not talk about the wind noise though.. it was windy in the desert.
I thought my ears were going to pop.. (i am not trying to be funny)..
you know how your ears get numb, when you ride coach in an airplane? Well that's the feeling I had when I got to my destination...
btw.. i think I could certainly do 28.5~29mpg if the weather was a little cooler, no A/C, and 1 or 2 passengers~ Does this car get the best mileage for it's size? Probably the diesel A8 has it beat i bet...

yeah...and also on freeway the battery from the hybrid doesnt really help. It basically runs just on the 3.3 engine, which EPA estimates a 24-25 hwy mileage.
So, with the advanced port and direct engine, with all the great tech they put into that engine, it is rated at 28 hwy isnt it?

Just got back from a weekend trip (Atlanta, GA <-> New Orleans, LA). Just me and a couple of pieces of luggage.
On the trip down (ATL -> MSY) I used Chevron Supreme (93 Octane). Avg speed ~75MPH w/ 30.5 MPG
On the return trip (MSY -> ATL) I used BP/Amoco ultimate (93 Octane). Avg speed ~77MPH w/ 28.5 MPG
Each leg of the trip was 494 miles, and I did each leg with a single tank of gas (with a little to spare, too). Unfortunately, the fill-up was $65 ... eesh !
Amazing machine, if you ask me !

Ah Ha! Does anyone know if the engine for CA is de-tuned for the lower octane?
