To see how well this car performed, we ran it at Tulsa Raceway Park with drag radials and it went 11.16 at 122 mph in the ¼ mile while being careful to take it easy off the line. The car was run hard off the line the second time around and it went 6.94 in the 1/8 mile and was pedaled down the track the rest of the way since there is no roll bar in the car. There is no doubt that this car will easily go mid to high 10’s in the quarter mile. For more details go to www.smotherssupercars.com/m73challenger.html. It is extremely quick and is gains a whole lot of attention wherever you go.
This car was also selected by Mopar Muscle Magazine to represent the Mopar division in the 2008 Year One Street Challenge in Atlanta, GA.
