That would probably be about 35-40 more horses than the 216 six, with a much more modern transmission that doesn't sap the power so much.
I don't remember if it was Motor Trend or Car and Driver that pitted the HHR in a comparison test against the PT Cruiser, but whoever it was ranked the HHR ahead of the PT Cruiser. Of course, considering that the PT is entering its fifth year on a platform that really dates back to 1994, while the HHR is all-new on a platform that debuted in 2003... if the PT had still won it would have been almost as dark a day for GM as releasing the Pontiac Aztek... which, BTW, is basically Prof's Trans Sport with an uglier skin.
