Mileage
My new Panel LT has the 2.4 and a five speed trans. From the very first tank I have been getting 28.5 mpg average and the only real trip (highway only) trip so far I got 31. 
no complaints here!

YOU HAVE NO IDEA HOW INTELLIGENT I AM. I TYPE IN CAPS BECAUSE IT
IS EASIER AND THIS IS AN INFORMAL SITE. I DIDN'T ASK FOR YOU TO
REVIEW MY GRAMMAR, PUNCTUATION OR LANGUAGE. WE WERE TALKING ABOUT GAS MILEAGE. BY YOUR IDIOTIC RESPONSE, I KNOW MY IQ IS
DEFINITELY HIGHER THAN YOURS. GO BACK TO SLEEP OLD MAN.

[QUOTE=nfboy;193718]I'll call this a YMMV thing. I am not saying your assertion is untrue, but I highly doubt that any increase in fuel economy is due solely or even in part, to turning the engine off at stop lights. ]
This does work and GM offers a Silverado that uses this type of technology as an option. It's like driving a golf cart. The engine shuts down at stop lights and starts when you press the gas peddle. It offers a 15-20% MPG increase over a standard 5.3 ltr V8 pick-up.

I'm doing this by memory, and I'm an old guy
, but when I witnessed some of the tests GM conducted regarding this, they discovered there was no(or not much) benefit to turning the vehicle off unless it was going to idle for more than 2 minutes. That may have changed.
So, do you know if there is some type of timer device in the option that you speak of?

I imagine there is something in the computer that shuts the engine down at a complete stop. Throttle position sets it for start-up.
The vehicle was first shown at the National Lawn and Garden show in Louisville and at that time there was a ride and drive set up for all who wanted to try it. 2 years ago it was also shown at the Fed-Fleet show in Los Angeles. I have only seen it in 1500 Silverado p-ups. Not sure if it was also offered on any other model.
There is also some reduction on rated emissions since the truck will not just sit and idle. This feature is also becoming required by California on I believe 2010 commercial trucks to reduce emissions. Problems are anticipated because some trucks work at idle.

I took my hhr with 2.4 to Birmingham, Al from Pensacola, Fl this past weekend. I was impressed with how well my little car did. Handled very well, accelaration was great going around trucks, etc....much better than I had been led to believe. I have been getting 31mpg consistently when just driveing the interstate around here But this weekend, inluding the weekend in Birmingham, stops for bathroom and then the long stretch between Pensacola and the interstate...I got 28.5 overall. I am quite happy with that. I used the dash dic and also kept track of mileage and how much gas I used...very similar numbers either way. Very happy with my hhr overall! A few minor complaints...don't like the upholstery feel...so getting some seatcovers, cant stand the armrests so just don't use them. By the way I have the automatic transmission and only about 1500 miles on it...I just bought a few weeks ago. I will also mention that I saw quite a few hhrs on I65 and they all looked to be keeping up with traffic which was going, for the most part, 75 to 80 mph.

I Appreciate Everyone's Comments. First Of All, When You Are Posting Your Mileage, I Wish Everyone Would Remember To State If They Have The Auto Or Manual Trans, What Year The Hhr Is, And How Many Miles They Have On It. However, Please Note - I Know All About Driving Conditions, Hills And Flat Roads, Jackrabbit Starts, Tire Pressure, Toping Off The Gas Tank, Etc. I Manually Calculate The Mpg Each Time I Fill Up. The Dic Is Always Very Close To My Manual Calculation. I Still Think The Mileage Stinks For The Amount Of Highway Driving I Do. Before I Got The 2007 Hhr (auto Trans), I Had A 6 Cyl Pontiac Grand Prix 3.8ltr. 200hp. I Got About The Same Mileage On Her, Give Or Take A Half Gallon And She Had Twice The Power Of The Hhr. I Dont Even Attempt To Pass Anyone Anymore. The First Week I Drove It I Knew The Hhr Just Cant Do It. It Cant Even Get Out Of Its Own Way. Getting An Extra Half Mile Per Gallon, While Driving On The Highway And Driving Gently, Just Isnt Worth The Investment I Made. I Brought It To The Dealer And After Leaving It There All Day, I Went To Pick It Up And The Idiot Service Mgr Says To Me 'there Is Nothing We Can Do About The Mileage!' Then Why The Hell Didnt He Tell Me That When I Made My Appt? I Dont Understand Why I Should Be Happy With 21.5 Mpg When The Majority Of Owners Are Doing Much Better. This Will Be My Last Gm Car. No Wonder They Are In Trouble. For Anyone Looking - Stay Away From Schumacher Chevrolet In Little Falls, Nj. They Were Great Until I Paid Cash For My Car. Once I Drove It Out Of The Showroom, They Forgot My Name.
