Isn't the upcoming Avalon supposed to have 31 mpg hwy?

We can no longer assume Toyota and Honda the efficiency benchmarks. Toyota and Honda needs to follow suit with 6 speeds to compete for highway numbers.

Of course, I wouldn't call this that amazing. After all, the 6.2L 430hp V8 Corvette gets 26mpg highway. That's what a high 6th gear and bullet-like aerodynamics will do.
The mustang gt gest 26mpg too

Chances are you will get better with the MT if you care to. Do some short shifts, which obviously isn't ideal for quick acceleration, but is more valuable to saving fuel than any automatic I've driven. No that's not fair. Any non hybrid auto that I have driven.
Fair enough. However, 19 mpg city in a coupe that has 305 HP and weights under 3500 lbs ... is nothing really special or exceptional.

The highway fuel economy is surely impressive, but again part of that is thanks to gearing.

The 2011 Avalon is supposed to get 20/29 EPA fuel economy. Slightly better city economy than 2011 Mustang V6, but slightly worse highway economy, so roughly equal.

While the Avalon does have 29 HP less, it's likely going to weigh more than the Mustang V6.

Yeah, it's not great, but it is an improvement. I am surprised that we aren't seeing more engine start-stop technology since supposedly it really does help save fuel.

I would expect more automakers to be using it. Toyota already uses for example stop-start tech on several non-hybrid models in Japan and Europe. I would expect them to bring this tech to next-gen North American models.

I wonder what the cost of the system are? If it's a little pricey it could probably be good on the next gen V6 Camry (where the higher costs wouldn't be so bad).

I'd love to see start-stop on all the next gen Lexus vehicles.

Big Kudos to Ford here with this new engine. Yet it STILL has 300hp.

Now that is "Advance"
well thats because US EPA tests favour constant driving at highway speeds.

Your real life is going to be very different between v6 and 4cly.

And it seems a lot of latest cars are being optimized for latest EPA tests, and real life figures are never as impressive.

you do not see start/stop because:
a. it is freaking useless in real life
b. EPA fuel tests do not favour it, so manufacturers can not claim anything on EPA official numbers.

Why is it useless in real life? Because in most cases, it will not always shut down your car at traffic stop (and thats only where it will stop it btw). If you want AC on, your car will never "stop".

You need much bigger battery if you want AC to work, basically you need mild-hybrid solution.

Not likely, today modern auto trannys short-shift more consistently than most drivers, in the interest of max fuel economy.

.
Real life 4 banger mileage is better not because of cylinder count, but because of smaller displacement, with all other technologies such as DI, DOHC, 4 valves per, etc. being equal.

I assume that by "other technologies" you mean fuel mixture as well. No matter what the displacenent, the richer the mixture (more gas to less air), the better the mileage. The average throttle opening also makes a difference. That's why some V6s actually get better average MPG in some vehicles than equivalent, smaller 4-bangers. The V6's are driven at a smaller average throttle opening, because the engines produce more power and, under high-load conditions, don't have to be strained as much. A heavily-loaded four-banger sometimes burns more fuel than a six, because of the higher throttle opening.
