The Chevrolet SS--which is basically an Australian-made Holden VF Commodore--recently went on sale in the United States, and it didn\'t take long for Hennessey Performance, an American tuning company, to get its hands on one.
Fitted with its HPE600 Supercharged upgrade kit that bumps up the car\'s power output from 362hp to 600hp, the modified SS was taken by Hennessey Performance to a closed toll road in Texas. Using its Racelogic GPS data logger and the speed guns of Texas\'s law enforcement officials, the aftermarket tuner tagged the SS at a top speed of 262kph.
While that seems painfully slow for a 6.0-liter performance sedan with a supercharger that nearly doubles the car\'s power output, Hennessey Performance claims that what held the car back was its factory-fitted six-speed automatic transmission, which supposedly prevented the car from exceeding its top speed.
While we wonder why Hennessey Performance didn\'t go around the issue with the transmission before doing the high-speed run, we\'re sure that once the issue has been resolved, we\'ll probably see them do a similar run again with the SS in its full, unbridled glory.
We might even see them obliterate that 262kph top speed since Hennessey Performance actually sells an HPE1000 Twin Turbo kit that can boost the SS\'s output to 1,000hp provided that the transmission has seen a performance build and torque-converter upgrade.
Does this make you want The Covenant Car Company Inc. (aka Chevrolet Philippines) to bring the SS into the country? After all, General Motors Southeast Asia did say that they needed to hear from interested customers before they would decide whether to sell the car in the region.
