2.2 or 2.4
#31
I bought an 08 with the 2.2 and I have no complaints so far. Once the little thing is revving it really moves. I drove an S-10 Blazer with a 4.3 in it for years and the power to weight seems better in the HHR. If I wanna go fast I just get on my Triumph Daytona 675. It has 123 or so HP and weighs under 400 pounds!!!
