Remember though, that there are 2 different transmissions in the LX's a 4 speed and a 5 speed w/autostick. Also a RWD and AWD version. On dry pavement, the RWD should be a little quicker than the AWD. Yes the LX's are heavier, but the engine puts out 8-10 more hp and I believe the RWD transmission robs less power than the FWD one in the LH's.
"Tuned up for this year with a variable-length intake manifold, the big 3.5 pulls hard but doesn't generate grins like the Hemi. We ducked the cops on a desert back road to steal a 7.5-second 0-to-60 with a 15.8 quarter-mile at 89 mph." ~ Car & Driver 2004
"Nevertheless, our Intrepid R/T test car managed to slice a second or more off the acceleration of our last 3.2-liter Intrepid. Weighing 75 pounds less than our last 300M, it managed to stay 0.1 second ahead of the Chrysler to 60 mph (7.8 seconds) and through the quarter-mile (16.0 at 89 mph). Top speed for our sleek and slippery Dodge climbed to 139 mph." ~ Car and Drver June 2000
Not set in stone, but I've found Car and Driver to be pretty accurate with thier numbers. Much better than Motor Trend, Edmunds or Road and Track. They did a test on an Intrepid SE and they said 0- 60 mph in 10 secs. I was like, b.s.! because it seemed faster. But I did some runs and I'll be damned my Intrepid was 10 secs.
So off the line about the same, although the LH's will pull ahead at higher speeds because of the better aerodynamics.
