It's a Christmas tradition … in Texas.
Hennessey Performance has broken its own unofficial record for the fastest speed achieved by a car with a decorated Christmas tree on the roof.
The sports car tuner has been making the Christmas Tree Run for the past few years and hit 192 mph this year with a Ford Mustang Shelby GT500, despite the added aerodynamic drag created by the conifer.
Not just any old GT500, but one equipped with the Hennessey Venom 1000 package that boosted its horsepower from 760 hp to 1,000 hp.
