Ford vs. Audi
"Recently at an auto show Ford showed off its 5.0-liter, 412-hp engine in the 2011 Mustang as an example of making a performance V8 fuel-stingy. The EPA rates the car at 26 mpg on the highway"
Am I missing something? How can Ford's V8 have better MPG than Audi's V6?

My RS4 gets 26 on the hwy. The Audi has AWD which has more mechanical losses.
From Ford:
Fuel economy also is aided by engineering a lightweight powertrain. The engine, as shipped, weighs just 430 pounds. This represents a weight savings of more than 20 percent versus the previous 5.0-liter offering. Lower mass can be attributed to the aluminum block and heads, the lightweight composite intake manifold, composite cam covers and hollow camshafts.

Weight and mechanical losses mentioned earlier are huge factors against MPG.
Don't confuse highway MPG with stop and go MPG. The 26 highway rating is a result of higher gearing in the Mustang, possible because of lower curb weight and rolling resistance. The Q7 has more than 6000 lbs to push compared to a Stang with about 3600 lbs. The Q7 has the AWD frictional losses and has much more frontal area causing more wind resistance.
If you compare the city MPG ratings, they are much closer or even better with the V6 Q7.
I get about the same city MPG between my 3.6 Q7 and 6.0 liter Corvette. But on the highway, the Corvette barely turns 1500 rpms to do 70 mph. I get about 25 highway on that 400 hp 3300 lb car.

Vette, new Stang, incredible HP and MPG. Really like the new Camaro also (not too sold on the Stang design-something about the slanted rear bumper looks wrong). Am happy to see Ford come out with some new & decent vehicles.
