Replying to: explorerx4 (Sep 17, 2009 2:05 pm) concerning aerodynamics, which mentions that the 09 gets 1 mpg better than the 08, due to a reshaping of the front.   I suspect that's more marketing hype. It gains 1mpg in city and highway. City mileage as it's tested would not be largely affected by such a small aerdynamic change. If the increase was only on highway mileage, I'd believe it, but since it's both, I suspect the changes to the compression, cams and fuel injectors made the greatest impact. It's apparanetly slightly more efficient at part throttle from the changes, even though peak torque output has not increased.   I think the modified front end may have helped, but was a smaller factor.

"   The city MPG is because of the new 2.5L engine, they were able to use it more efficiently than the old 2.3L, so yes, they did adjust a lot of the internal timings & etc.   The highway mileage, believe it or not, is helped by increasing the width of a very small chin spoiler. In my 2008 it stops short of the edges of the front bumper. In the 2009-2010, it extends further by about 3 inches on each side. Apparently this managed to cut the aerodynamic drag caused by the front tires...

I thought you were talking about the 2010 CR-V in terms of it's mileage going up 1mpg.   Although, don't be fooled on the 2010 CR-V. IT makes 180HP now, but in real world driving, there won't be a noticeable increase because most all the gains were above 5000 RPM. Most of it likely above 6000.   On the Escape. Yes, the 2.5L is a big improvement. The 2.3L was getting dated and underperformed in the standard configuration (not the DI or turbo version) and a weak spot for both Ford and Mazda.

Replying to: motoguy128 (Sep 18, 2009 9:07 am) i think the biggest difference is the transmission. the '09 3.0 is about 20% more powerful, yet delivers better mileage. it doesn't use direct injection, either. the 6 speed shifts much better than the previous 4 speed.
#8530 of 8531 Economy improvements by motoguy128 Sep 21, 2009 (5:48 am)
An increase in power in a engine is a tricky thing ot evealuate and not a good measure of the engines overall performance. Smoetimes more power is gained by using more fuel, other times it's gained by better overall combustion efficiency, such an increase in the compression ratio.   The transmission was clearly the biggest improvment, but the increase in engine performance may have allowed hte enigne to use a lower gear, where it previously would have unlocked the torque converter or downshifted.   I still think overall the EPA ratings are somewhat suspect. A better measure would be to publush fuel consumption numbers for the vehcile when traveling at a steady speed, and when accerating from a stop to 60mph at a given rate, and holding a given speed up an incline. It would be much more objective than the simulated test cycle the EPA uses now. Replies to this message: explorerx4 (Sep 25, 2009 4:41 pm)

Replying to: motoguy128 (Sep 21, 2009 5:48 am) i don't care about objective. the real world difference is approaching 20%. pretty good with that.
