Something to keep in mind is the effect of altitude on HP. A normally aspirated engine will lose approx 10% power for each 1000' gain in altitude. My ML 430, for instance, is rated at 268HP at sea level ( I forget at what RPM), when I get up to where I live at 5000+ ft. it's down to approx 158 HP. That's a signifigant loss, which BTW, you won't suffer with either of the XC90 engines. The turbos make the eng perform much the same as at sea level. Food for thought. I posted this thought on the other XC90 forum (which shall remain nameless), and thought it was worth posting here. It makes the XC90 all the more desirable, and sort of negates all the stuff about the 4sp, 5sp, 6sp tranny. <IMG SRC="http://www.swedespeed.com/ubb/biggrin.gif"><P>
