For the model years 2005 and 2006 the stock 2.2 L61 engine was rated at 145hp and 155lbs. of torque, however http://www.chevrolet.com/cobalt/specifications/ lists the 2.2 Ecotec at 148hp and 152lb.-ft of torque. Why the change? Is the factory tuning for the 2007 model year different or are these new numbers just a revalution of what the L61 was always putting out?

i actually think hm has a new rating system. I don't remember where i heard it, but i did hear it somewhere.

The SAE is pushing it's new HP rating Standard.

Probably has same amount of power, notice the torque is rated at a different rpm, 155 @ 4000 (2006) 152 @ 4200 (2007)

hp only jumped by 3, not worth anything.

Just retested the motor, manufacturing chould have change tollerances by a few thousandths, chould be the reason for the 3 hp up and 3 tq down.

Bottom line
Its the same engine and has the same amount of power. (not enough for me )

what really sucks is the Ion is still rated at 140HP and 145HP, I wonder if you guys REALLY have us on tq or is that just Chevy BS.

It's probably in the way our exhaust works or intake ducts or something. Or Chevy BS

the ion has the elctric power steering also, right? cuz the last year cavs didnt and they had the same 2.2 with 5 horses and 5 lbs of torque missing.

IonNinja
