9. Dodge Challenger Drag Pack
Drag racing is big in the U.S., so car manufacturers sometimes produce specially-prepared versions for racers in the stock car class. Those cars started its life as ordinary models, but have been turned into fierce drag racers by eliminating all that is unnecessary and adding more power.
The best example of this is the crazy Dodge Challenger Drag Pack model. It debuted in 2011 as a non-street legal model they sold only to professional racers and teams. Basically, this was a stripped-down Challenger with a Viper V10 engine, 600 HP and drag tires. This car appeared on race tracks across the country, shattering past records with a 0 to 60 mph time of only 1.80 seconds.
