A YouTube video shows the wagon edition as it surpasses 1058 horsepower during a dyno test, after swapping its 556-horsepower 6.2-liter V8 for an even larger 7.0-liter mill boosted with dual turbochargers.
Performance figures have yet to be published, though the coupe is claimed to reach 60 mph from a standstill in less than three seconds. It can complete a quarter mile in just over ten seconds before topping out around 242 mph.
It is unclear if the wagon offers the same range of upgrades as Hennessey’s two-door monster, such as carbon ceramic brakes, 345/30-20 rear wheels and lowered suspension. In its current form, it does appear to lack the special hood and other eye-catching bodywork of the tuned coupe.
Hennessey has yet to announce availability details and pricing. More than double the stock horsepower likely won’t come cheap; in contrast, the coupe fetches $295,000.
