I am in the process of looking for a HHR.
Just wondering which engine will be the less troublesome in the long run?

 

I put over 42,000 miles on a 2.4 auto without even the slightest hint of a problem. I didn't get any more miles on it because I traded it in. I don't know if that helps, but I thought I'd put my experience out there for you.

 

the engines are nearly identical except cubic inches. both newer ones have variable valve timing. the ecotec is a very good engine found in a ton of cars. 2.2l will get you better gas mileage(2-3mpgs), while the 2.4 has nearly 30 more horsepower. my first car was a cobalt with a 2.2 auto. i traded that in for the 2.4l auto in the HHR. it was definitly a big 30 horsepower when it came to my camping trips and hauling stuff around. my cobalt was slow as a dog with passengers, the hhr wasnt nearly as bad. hope this helps

 

Both will give you a good life. They are excellent built motors and should last a long time with proper maintenance.

 

I would go with the 2.4 myself if possible.
I had one and was impressed with the power and smoothness.
I thought I read somewhere that the 2.4 had a heavier duty block or rods
Either way both awesome reliable great gas mileage motors

 

133k on my 2.4L and no problems. Only had to replace 1 sensor. Get an avg 28-29mpg regularly.

 

2.4L here, love it...

 

2.2's and a 2.4 here, love 'em and no problems.

I do notice a roughly 2% difference in fuel economy favoring the 2.2 over the 2.4, but that's such an insignificant number that it doesn't really matter.

As for driving characteristics, you get a bit more low end "oomph" with the 2.4, but not much. The 2.2's are more eager to rev, and in my opinion, they are the crisper engine when it comes to throttle response and overall "Fun to Drive-ness".

 

I'm looking at a 2011 fully loaded LT 2.4 Silver 20,000K for 19,900.

 

take 2.4
Reliable, economical and powerful. The ideal heart for Hippo.
This engine is a champion. Mark - LE5. Some time ago I read: LE5 several times awarded the title of "Engine of the Year" nomination "Volume - traction" (if memory serves me). In short, the engine - good luck to the GM. How 3SFE for Toyota.
With regard to fuel economy - no worries. Eating more, but the difference is not great. If half a gallon - I'll be very surprised.
