You just know that the biggest name in horsepower wouldn't be able to lay off GM's hottest car, and the result is this 2010 Chevrolet Camaro HPE 650. John Hennessey doesn't mess around, either, with this bright yellow F-body cranking out an astounding 655 horsepower and 642 pounds of torque. Yeah, it's legit and there's just no way you'll be able to buy more speed for less cash anywhere else. It isn't subtle, but when you can run 11-second quarter mile times at will, well, there's not much reason to keep a low profile. Actually, the HPE mods are pretty low-key relatively speaking, and most folks on the street won't see this as the threat it actually is. There are some black side skirts, a carbon fiber chin spoiler, and a few Hennessey badges, but by the time anyone really notices that stuff, it's already too late. With just 4418 actual miles, this Camaro is still virtually new and hasn't been abused, raced, or flogged, so the sheetmetal and paint is factory fresh. The searing yellow paint is better than you'd expect for GM, befitting a much more expensive car, and the retro-inspired look is aging well, because this car still gets a lot of looks on the street. Add in some satin black stripes, oversized chrome surrounds for the exhaust pipes, and the hunkered-down stance (HPE is nothing if not great at lowering vehicles), and you have one heck of an intimidating Camaro. Inside, it's pretty much the same as any other Camaro you've seen: deeply sculpted leather buckets, a fat steering wheel, retro-style gauges, and tons of creature comforts. Hennessey embroiders the headrests for you and puts a serialization badge on the dash (this is #22, by the way) but otherwise leaves well enough alone. As you'd expect, it's like new, which is the highest praise we can give any vehicle, and obviously everything works. The seating position is pretty good if you're intending to go fast, although you should familiarize yourself with your surroundings, because this car gathers speed so quickly, you'll find yourself in another zip code before you can count to 10. Don't say we didn't warn you. And if you just want to cruise, it's happy to do that with ice cold A/C, a kickin' stereo system, and great road manners thanks to a deep overdrive on the 6-speed manual gearbox. You even get a decent-sized trunk as part of the deal, complete with cargo net. Under the hood, there are big, obvious changes. One, the intake manifold has been replaced by a supercharger. Two, there are yellow coil covers. And three, horsepower is up by about 50%. The central part of that is a TVS2300 supercharger with cold air induction, which crams pressurized air into the upgraded LS engine. The heads were ported, there's an upgraded camshaft inside, and it's been fitted with high-flow fuel injectors to add fuel to all that extra air. Of course it's been properly tuned so it starts quickly, idles nicely, and doesn't get fussy. Throttle response is instant, and it's still emissions legal thanks to stainless headers, high-flow cats, and a stainless exhaust system that don't mess with the exhaust output. Still, it sounds nasty. The suspension is pretty stock save for the lowering job, and those big 3-piece wheels with blacked-out centers and oversized rubber totally stuff the wheel wells.
