hybrids ... not impressed

Just saw the new write up on the Ford Fusion hybrid. Sounds like a nice car, but not really impressed by the fuel mileage. Same with the Nissan Altima hybrid. Both get 34 mpg highway. Good, but not really impressed I have to say. I once got 31 mpg hwy on my 2001 Intrepid SE (2.7L). If I took it easy on the hwy, was no problem to average 29-30 mpg. So all this new technology and cost to get 3 - 4 mpg more? :grlaugh:

Hybrid technology does absolutely nothing for the highway milage. On the highway at constant speed cruising, the electrical machine is off and the only thing that determines the gas milage is the gas milage of the engine at the speed you choose. As a matter of fact, because you have to carry the electric machine and the battery pack, this car might actually get worse fuel economy than if the vehicle had the same engine but is not a hybrid.

A more relevant metric is what is the gas milage on pure local driving. That's where regenerative braking, engine off during idle, electric launch can really help the gas milage, WITHOUT compromising drivability. If i'm not mistaken, the vehicles you listed are classified as mild hybrids where the battery pack is relatively small. So the engine is not downsized significantly. Therefore there's even less chance for improvement in terms of highway driving.

So far my Intrepid equals the mileage of both hybrids and gets 35 mpg at 65 mph on cruise, so I guess I won't be needing a hybrid anytime soon.

They are also usually less cost effective than a comparable gasoline only car...after 60 months of payments (all payments plus gas minus vehicle equity) the gasoline car always comes out ahead....sometimes more than $1000 ahead.

Hell i get 30.7 mpg with my 2009 Sonata Limited city/hwy. If i drive 55 mph i can get 41 mpg on the hwy. Even at 80 mph i get 28 mpg.

Do any of these cars use cylinder deactivation at highway speeds? I thought one of the Honda Accords did but I was wondering how much that helps highway mileage and why some of these other cars don't use it. I really miss the 28mpg I got in my SE going 75 all the way to work.

Chrysler is suppossed to add cylinder deactivation to the V6's also .... or so I hear. Not sure how much that would improve gas mileage. I think something like 2 mpg.
Toyota Yaris owners that have the 3 door hatchback model have been getting far above the EPA rating. One Car site tested one and got an honest 49 mpg. I think Toyota doesn't want people to know this because it might compete against it's own Prius. Especially since it's so much cheaper.

For work I drive a 2009 Camry hybird I actually love it, its peppy enough to merge, and when i'm stuck in the city of Pittsburg the motor doesnt even run its perfect for high MPG in the city....When I have to travel...the highway its just like any other car but city driving I love hybirds i'll just never toss out the extra cash for one =]

"to get 3 - 4 mpg more?"

It's not just 3-4 mpg more, it's 3-4 mpg more in a smaller car.

Hybrids are better if you do a lot of city driving and very little hwy driving. For highway heavy driving clean diesel is a better option. Look at the hwy gas mileage of the Volkswagon Jetta TDI, IIRC its about 40+ mpg.

The EPA just applied a correction factor to the window sticker, basically so people who purchased a Prius wouldn't be pissed. Now almost everyone is hitting or beating the window sticker.
Did you see the Motor Trend where the '09 Camry hybrid got about 35mpg on the highway?

The electric system is how the highway mileage is better. The planetary gearset is the transmission.


I still wish Nissan would bring over the VQ25hr V6

That is with a 5 speed auto, bring on the 7 speed auto!

9/11, still an inside job

I tend to agree that hybrids are an overly complicated way to improve gas mileage. Top Gear did a challenge in which they drove over 700 mi on one tank of fuel (diesel cars). The cars were a small compact diesel 3 cylc VW, a Twin-Turbo diesel Jag, and a diesel Subaru. The VW was getting mileage in the high-60's to 70's. Hell, the fullsized Jag was getting fuel economy in the 40's and 50's. It will probably be re-ran tomorrow at 9:00 p.m. on BBC America (usually encore's of last week's show).

My point is, we can improve mileage of conventional gasoline or diesel engines without having to add motors, battery packs, and other overly complicated systems. I believe clean diesel is definately an option; hell BMW has a 7-series that will run on hydrogen or regular fuel.
