Not exactly "The Tortoise and the Hare": This Web video shows a Cadillac CTS-V Wagon in a drag race with a Porsche 911 Twin Turbo
The CTS-V Wagon has been given a 650-horsepower Hennessey V650 upgrade and drag radial tires.
The upgrade includes a supercharger pulley and snout upgrade, stainless-steel long tube headers and midpipes, and a high-flow catalytic converter.
The Hennessey wagon offers 658 brake horsepower (bhp) at 6,200 rpm. And despite weighing almost 1,000 pounds more than the 911, the CTS-V Wagon bests the 480-horsepower Porsche.
