Suppose this will work on my GMC??..........terry

Going the extra mile
Regulars on these sites report mileage of 60 mpg, 70 mpg, even 80 mpg over
extended periods. Of course, the average commuter can't even begin to
approach these levels of fuel economy. Most of us wouldn't want to try.

Many of the techniques embraced by hypermilers are uncomfortable, illegal or
downright dangerous. Some block off their car's grille to improve
aerodynamics; some shut their engines off while coasting. They'll remove
side mirrors to reduce drag, remove a power steering pump or buy a new set
of tires in hopes of improved coasting.

But by applying common sense and some of hypermiling's simpler techniques,
it is possible to improve significantly the fuel efficiency of any vehicle.
Hypermilers report daily mileage -- even in bone-stock cars such as a Honda
Civic, Ford Escort or Toyota Yaris -- well into the 40s.

Little things mean a lot
In fact, Gerdes says, following just the basics, like parking so that you
can pull forward rather than wasting gas backing up, will improve your own
mileage 25%. This might even be a bit of an understatement.

At its HYPERLINK "http://www.fueleconomy.gov" the U.S.
Department of Energy says that by following the speed limit and swearing off
aggressive driving (rapid acceleration and deceleration), drivers can
improve mpg by anywhere from 12% to 55%. An additional 19% improvement can
be achieved, it is claimed, merely by keeping a car properly maintained.

Editors at HYPERLINK "http://www.edmunds.com" achieved similar
results when they put to the test some widely accepted driving tips. On
average, fuel efficiency improved 12% when speed limits were followed, 31%
when aggressive driving tactics were avoided and an additional 7% when
cruise control was used. Limiting the time spent idling also led to
improvements of up to 19%.

Not only is significantly improved fuel efficiency achievable, it's easily
achievable. Hypermiling builds on these relatively simple concepts.

Gerdes proved this recently when he put a visitor behind the wheel and
talked him through a 30-mile trip to Chicago's O'Hare International Airport.
The driver, previously untutored in the ways of hypermiling, averaged 51.2
mpg in Gerdes' 2005 Honda Accord, exceeding the EPA's highway rating for the
vehicle by more than 50%.

Hi Terry,

Did they mention GMC's?
Could be raising the rear end would help, that way you would always be going
down hill.
Seriously I wonder if there are any of these mileage freaks in the motorhome
community?
I would think just about anything that applies to a car would apply to the
GMC, particularly accelerating slowly and driving slowly probably about 45
MPH
I had a 14 foot step van (bread truck) I used as a service truck, I had a
Pontiac 455 in it and I always hauled butt got about 6 MPG typically. One
day the engine developed a problem and was running on 7 cylinders, I decided
to limp back over a 110 miles, I got over 11 MPG on 7 cylinders!!

I neglected to say I was doing about 40 to 45 on the way back instead of the
usual 70 to 75

Wayne Gerdes website is cleanmpg.com.

I'm a member and have a Yaris. The techniques do work with the car. If the GMC had a consistant route it would be possibe to test any changes. Most of us are running a scangauge on the vehicles to get feedback on the fly.

I have been very happy with my Toyota Camry Hybrid. Long term mileage has been slightly over 40 mpg and takes into account every drop of gas I have put in. I drive "normally" at about the speed limit on whatever roads I am on. Great power (0-60 in 7.5 seconds) and not a small or light weight car at 3800 lbs. Much nicer than the Prius Hybrid that Toyota makes, and not a lot more expensive either.

Unfortunately, the weight, efficiency, and aerodynamics of the GMC are not nearly as good, but then I understand the differences in purpose.

A good step forward. I'm glad you have the experience and are willing to share it. How much more did you pay for the vehicle that a similar conventionally powered Camry? The web site shows a premium of $6275 vs. the conventional LE. The hybrid does not seem to have any special luxury features. The city mile ratings for each are 40 mpg vs 24 mpg.
Seems to me its going to be a while before that investment gets paid off by gas savings.

The car cost $26,700 and a Camry LE was about $23,000 list as I recall. No discounts on the Hybrid but some on the LE. Last year the Fed's gave a tax credit of $2600 on the Hybrid (over now) so the real cost was $24,100 to me.

The hybrid is quite differently equipped than the LE. Alloy wheels, traction control, skid control, dual climate control are all standard on the Hybrid. Traction control and skid control, and dual climate control are not even available on the LE or LX. All Camry's have tire pressure monitoring, and 400 watt stereo with Bluetooth phone capability. All have 7 air bags. Only the Hybrid has a continuously variable automatic transmission.

It also has keyless entry and no key to "start". Just keep the key fob in your pocket, open the door and get in and press power button. Not available on the LE or LX. Toys, granted, but fun toys.

No conventional starter, alternator, power steering pump, or AC compressor. They are all electric. One small belt for the water pump only.

The AC is wonderful when parked. I left my 90 yo dad in it one day when it was 100+ while I went into Costco for 15 minutes. The engine was not running, but the all electric AC was. As I came out, I heard the engine "start" to recharge the batteries. He was completely cool, but the engine was not ruining for those 15 minutes. He said it had not run while I was in the store, just started for the first time as I came out.

It is a technological car for nuts like us GMC owners. We like our toys, huh? (GMC content)

I sound like a Toyota salesman. I am not, but it is a great car. However my experiences have sold two others to friends, and that gets me $200 for each one from the dealer, who only does word of mouth advertising, not paper advertising. They put their advertising money into the pockets those who send friends to the dealership.
