2014 Chevrolet Corvette Stingray C7 by Hennessey

The all-new 2014 Chevrolet Corvette Stingray is gonna be good enough for most people, but not for Hennessey Performance. The gearheads at this tuning house have unveiled a series of upgrade kits for the C7, including a top-end package that will yield a breathtaking 1,000 horsepower. The HPE1000 package ($67,950 on top of the C7’s price) is at the top end, bringing twin superchargers, a stainless-steel exhaust system, air-to-air intercooler, forged aluminum pistons, and more under the hood. You can also pick up other Hennessey goodies like monoblock alloy wheels, Michelin Pilot Super Sport tires, and Brembo brakes with carbon-ceramic rotors. You know; if 1,000 hp isn’t enough.

Hennessey Performance CTS-V VR1200 Twin Turbo

For the perfectionist… for the, I-can’t-be-seen-in-anything-but-the-fastest-car-on-the-road guy… comes the Hennessey Performance CTS-V VR1200 Twin Turbo. Just 12 of these voracious creatures are being built, and with good reason. The specs are insane. The 427 CID (7.0L) aluminum V8 engine delivers an astonishing and ungodly 1,226 horsepower and 1,109 lb ft of torque. That (and the gorgeous looks) gets you from 0-60 mph in 2.9 seconds, which probably also gets you on the radar of every nearby cop. But with a top speed of 242 mph, is this really something to sweat?

Hennessey 800-hp Jeep Grand Cherokee

Hennessey Performance (HPE) seems hellbent on creating a vehicle that can not only outrun an avalanche, but climb over the top of one too. The HPE800 Twin Turbo Jeep is based on the new Jeep Grand Cherokee SRT8, with the factory 6.4 L Hemi getting bumped to 7.0 L (426 cubic inches) while adding a twin turbo forced induction system. What you’re left with is a road-ravaging beast of a vehicle, capable of 805 hp and 823 lb-ft of torque. Yes, it’s a Jeep that does 0-60 mph in 3.1 seconds.  The state-of-the-artness continues with an upgraded transmission system and torque converter, 15.1 inch Brembo brakes front and rear, a lowered sport suspension system, lighter alloy wheels, carbon fiber front splitter and a custom leather interior with Alcantara steering wheel. HPE is only conjuring up 24 of these monsters, and they’re going for $235,000 a pop.
