According to several sources, the ratings for the 2010 2.2L engine is 155 hp with 150 lb-ft of torque. Wikipedia says it puts out 149 hp and 152 lb-ft. Which is correct? I know that Wikipedia can be horribly unreliable but they had to get the numbers somewhere. My gut says 155/150 is the correct rating but is it possible Wikipedia is right?

149 was for the 2006-?. 155 was in the later years when the engine got upgraded. Don't recall the exact year but it may have been when they became flex fuel capable.
edit: apparently the 2006 L61 was only rated at 143hp. 149hp, 07-08. 155hp in 09-11 when GM changed to the LE8 engine version.
Same applies to the 2.4. They saw a measly increase of about 3hp to 175.
The SS 2.0 was always rated 260/260 for it's 3 years of production.
(auto trans models had a 235hp detune program for the lower gear. )
