You are in the Chevrolet HHR
What is this discussion about?

27-30 MPG isn't typical average mileage other people post unless they only drive on highways.
Most cars get good mileage driving at a steady highway speed (even a 268HP Camry can get 30 mpg on the highway), so 30 mpg on highway trips is expected, but mix in stop and go city driving other people say they get more like 22 MPG (which is V6 territory).
The problem with the HHR is that it seems to give you V6 gas mileage with the performance, noise and vibration levels of a 4 cylinder.
What kind of acceleration numbers have the mgazines got when the HRR has the automatic transmission? I only see test results with the 5-speed manual.

That's baloney, check Car and Driver...when they tested the new RAV, with that 268 HP engine you're talking about, they got 16 MPG! Even when they tested the 2007 Camry Hybrid 2.4L they only got 33 mpg and that car cost >$30,000!! You can buy a lot of gas for $10K. Besides the last new Toyota I bought was something of a nightmare. If I would have had to pay for everything that went wrong with it during the waranty period it would have been over $6,000. They'll probably stick the Turbo or Supercharged versions of the Ecotec in there eventually, maybe even a Hybrid...but you'll pay several thousand more either way.

A supercharged engine comes as an option in the fall.

Most likely the supercharged model will be manual transmission only since that engine is not available in automatic with the Cobalt. I guess that will be OK for hot rodders.
The 2.4 would probably be fine if it had a 5-speed automatic instead of that old 4-speed. A couple more mpg and a little better acceleration without having to drive and try to resell a manual transission model down the road.
The very heavy weight of the HHR is probably what causes the sluggish performance and so-so fuel economy.
The Edmunds review tested the HHR with the 2.4 engine and automatic at 0-60 of 9.5 seconds. That seems just adequate if a little slow.
If the 2.4 is that slow, then the 2.2 with automatic must really be dangerously slow for merging onto highways with a load of passengers.
A V6 would be nicer and would move the vehicle's weight around without working as hard, but their V6s probably don't fit the engine department or they would offer one.

Well, to put it in some perspective....in 1978 I bought a brand new Corvette off the showroom floor....L48...180 HP 3400 lbs....the 2LT is 172 HP 3200 lbs. The Vette got 16 mpg. Today when I filled up the 2LT the DIC said 27.9 mpg the trip meter said 279 miles...I chugged it till it was ready to overflow....10.0004 gallons = 27.9 mpg ..just like the DIC said.
So jaxs1, what vehicle out there, well loaded, station wagon like, that really get 27.9 mpg, for <$20K beats the 2LT?

Vibe, Mazda5 etc. etc..
Chevy just should not put engines designed for the much lighter Cobalts into such a very heavy vehicle as the HHR.
Or maybe the HHR just shouldn't be as heavy as it is and then the Cobalt engines wouldn't have to struggle to move that weight around as much as they do.

Put a 2.0L diesel in the HHR and I'll buy one in a heart beat.

The 2LT weighs 3155lbs/172HP = 18.3lbs/HP.
The Vibe " 2700lbs/126HP = 21.4lbs/HP.
The Mazda5 " 3389lbs/157HP = 21.6lbs/HP.
Once again, you are full of baloney.

The Caliber weighs 2966lbs/ 158HP=18.7#/HP
SRT4 Caliber weighs 2966lbs/ 300HP=9.9#/HP
Caliber RT weighs 3308lbs/172HP=19.3#/HP incl AWD

I don't have one but have driven a couple automatics and they move really good. I can't say how they would be with a load though.
