Unfortunately fall is coming to an end here in western PA, and the temps have already dropped in to the 20's in the a.m.'s. I've noticed a big difference in the way that the 450h runs. Seems a bit more sluggish, but mostly it seems that the gas engine activates as soon as you touch the pedal and stops a soon as you stop. It also seems like the transition between gas and electric is not as smooth. Later in the day as it warms up everything is back to normal. Just curious if anyone else has experienced this.
