Sure of what? I am sure the needle indicated at least 60 mpg at 70 miles per hour, and 50 mpg at 75 miles per hour, over a mile or so at each speed. I obviously do not know what real-life mileage would be with sustained travel since I do not yet have the car and only did a very short test-drive, and I do not know the accuracy of the gauge. I never pretended to.

I am not saying it has better highway mileage than a 2006 HCH either because, again, I have not driven it on a real drive, just a quick test-drive. Given Road & Track's results, its mileage is probably slightly worse (they got 38.3 with the Camry and 40.0 with the 2006 HCH).

For the record, I expect to get 35-38 mpg with the TCH, though it will probably be lower for the first tank or two (32ish?). But I also expect to get a car that is much faster, much smoother, and with a greater driving range.

Oh, and please stop comparing real-life MPG to EPA estimates. I got 96% of the EPA estimate with a 2000 Jetta driving extremely leadfooted, and 78% of the EPA estimates driving my 2006 HCH very gently, coasting alot, etc. You simply cannot use a fixed percentage to guess how one car does in real-life compared to another.
