I have beat my dads 300 (v6) but there is no way in the world a 3.6 Malibu will beat an R/T Charger. I'd bet he was playing with you or didn't know he was racing.I own a 2000 3.3l Dodge GC. Claimed HP is 158, 11 shy of the 2.4l in the Malibu. The Bu should weigh about 400lbs less but that depends on the models you are comparing. I suspect the 2.4l in the Malibu will beat it in 0-30, or 0-60 times; however, the 3.3l has a 43 ft/lb torque advantage. The seat of the pants feel gives a slight edge to the 3.3l in around town [short distance accelerations] driving.
As for the 3.6L - I easily beat a Grand Cherokee w/ a 5.7 Hemi, yesterday.
