Gas Mileage changes 2006-11?
It seems the mileage and HP changed each year the HHR was produced, so my question is what year gets the best mileage and which engine?

You are going to get a mixed bag of answers on the mileage. Mileage is really based on your driving technique. I have a 2.4L 2006 HHR auto running 87 octane and have averaged 30.6 mpg for the 81,000 miles that I have on the car. Max HP is obtained around 6200 rpm, now how often do you drive at 6200 rpm? At 70 mph, my HHR runs ~2500 rpm. Unless you are a NASCAR driver and on some track, the HHR isn't running at 6200 rpm.
If you have an SS version 2.0L turbo, it has lots more HP and the 2.2L has a bit less HP than the 2.4L. HP rating can be changed by what parameters where the reading are taken.. 6000 rpm or 6500 rpm. |
Ditto on the "mixed bag of answers on the mileage"....... Much of what you are seeing with GM's changes from year to year with the mileage is just a "numbers game" they play. HP and TQ numbers is also a game sometimes, but there were a few improvements, I believe the 2.2L got VVT at some point.
Most of us are getting around 30... some lower, it depends on driving technique and what your daily commute is like. :skull: |
I have a 2010 HHR 2.2L (LAP-VVT) and get about 30.9 mpg consecutively, with almost 50/50 driving. I've hit 32.5 once and was absolutely shocked.
I don't stomp on it or anything, I feel like I drive what would be the norm. |
At first, my mileage was ABYSMAL. I was getting 21-24 MPG. She was BRAND NEW then though. Now, with 6700mi on the clock, shes STILL breaking in a littler bit and I should see somewhat better results. My 2006 Cobalt SS/SC would get 30 consecutively as well.

My 2011 after 4 months as of today has around the city gotten 24 to 25 mpg combined city highway mostly city . Our only trip aprox 500 miles round trip it got 32.1 mpg not bad wife seems to have a heavy foot ! I get a tiny bit better avg mpg than she does :D but honestly its not much like 1 mpg more . I mostly run Sunoco and Shell ! Did run a couple tanks of E 85 and boy was that a mistake never again ! avg was about 25% less MPG just awful .
I didn't see a performance lose thou in the E 85 just really bad mpg highway and city :thumbsdow One more thing these little van wagons what ever you call it seem to have a sweet spot on the highway ! Mine is at aprox 69 mph with the cruise control on . gets a tad over 32 mpg |
Pretty sure Both engines went VVT in 2009.

My vintage 2008 2.4 has VVT,
the 2.2 went to VVT in '09 & I believe direct injection, IIRC. |
2007 2.4L has VVT also.....
