Suburban Terror: Hennessey offers upgrade packages for GMC SUVs

Lest you think that Hennessey Performance Engineering will only tune up your Dodge Viper or Cadillac CTS-V, feast your eyes on this little number showing one of the company's souped-up SUVs taking on a 2011 Nissan GT-R.

But Hennessey, not looking for a beatdown, drops a twin-turbocharged 427 cubic-inch LSX engine with high-flow cylinder heads, intake and exhaust upgrades, a performance camshaft and a laundry list of other parts to bring the truck's output to 1,000 hp.

In city driving, the 1.4-liter turbocharged Ecotec engine gets 29 mpg.
