I took my 05 Xfire automatic coupe with 11,000 miles to the drags last night.I made 5 passes with a best time of 15.12 and 92.6 mph.I was surprised at the times. In the past I have raced an 05 Chrysler 300 hemi and a 06 Dodge Charger hemiat the same track with similar times and speeds. Is this a normal time and speed for a automatic coupe????
