Hennessey HPE1000 builds a 1,000 hp 2016 Chevy Camaro

If the 455-horsepower 2016 Chevrolet Camaro SS isn't powerful enough for you off the showroom, ring up the folks at Hennessey Performance. The company can bump the coupe's output up to 650 hp if you want to keep the engine naturally aspirated, but supercharged versions can more than double the stock rating to 1,000 hp. To achieve such a massive boost in performance, the company performs a thorough suite of engine modifications in addition to installing the supercharger and intercooler. Among the biggest tweaks is stroking the motor to 6.8 liters from the stock 6.2 liters. To make sure the mill can handle the boost, it also gets forged pistons, billet steel connecting rods, ported cylinder heads, an upgraded valve train, new engine management, and more. Hennessey tests each car before and after on a chassis dyno and does up to 100 miles of road evaluations. The company claims this tune works with the factory automatic and manual gearboxes. The HPE1000 Camaro is available to order now. Clients send the company their 2016 Camaro SS, and the upgrades cost $65,000, which includes installation, John Hennessey tells Autoblog. The improvements also come with a one-year / 36,000-mile warranty. Unfortunately, Hennessey Performance doesn't have a video of the HPE1000 Camaro, but it does have a clip (below) showing the naturally aspirated HPE600 version, which boasts 526 hp at the rear wheels. Think of it as just a taste of what the forced induction model might offer, but we'd imagine with a screaming supercharger.

Nissan Leaf, Chevy Volt have best sales month of 2015

Things are trending upwards for the two best-selling plug-in vehicles in the US. Both the Chevy Volt and the Nissan Leaf had their best sales month of 2015 in May, with the Volt selling 1,618 units and the Leaf moving 2,104. The upward swings come at an interesting time, with lots of excess first-gen Volts waiting for buyers and some buyers already ordering their second-gen Volts. So far in 2015, the Leaf has outsold the Volt 7,742 to 4,397. While 7,700 Leafs is respectable, it's nowhere near the numbers that Nissan will have to hit to reach the 50,000 annual sales that CEO Carlos Ghosn says is possible in the US. Still, the Leaf had its best sales month since December 2014 (when it sold 3,102 units) in May, but last month was still down 32.5 percent compared to May 2014. Despite the smaller overall number, May represents a big positive for Chevy, which has seen sluggish sales for the Volt for a long while now. The 1,618 Volts sold last month are only 3.9 percent lower than the 1,684 sold in May 2014 and May 2015 was the best month for Volt sales since August 2014. Perhaps salesmen are ready to make deals, what with thousands sitting around on dealer lots right now. The next-gen Volt is due this fall, and the order books (in California, at least) opened up this week. Like every month, our full wrap-up of green car sales in the US is coming soon (the VW e-Golf, for example, hit a best-ever high of 410 sales). Until then, feel free to discuss the Volt and Leaf sales figures in the Comments. Green Chevrolet Nissan Electric Hybrid ev sales hybrid sales

Petrolicious visits a coachbuilt Corvette in Montana

There was once a time when most anyone could take a car to one of the great coachbuilders of Italy and have it rebodied into something entirely original. That's what one Gordon Kelley did back in 1962. And it's the story that Petrolicious tells in its latest video. An industrial designer by trade, Kelley penned his own design for bodywork to cover his '61 Corvette, and brought it to Vignale (today owned by Ford) in Turin for realization. The stunning result became known as the Kelley Corvette. It appeared at major auto shows and graced the covers of magazines, and with good reason: as you can see for yourself, Kelley's design and Vignale's work came together beautifully, and have gracefully endured the test of time in singular fashion. Today the car's custodian is one John Breslow, based out in Montana – a state that not only doesn't require a front license plate (which would be a crying shame to mount in that front grille) but also has some of the highest speed limits in the country. Breslow likens the Kelley Corvette to "a Van Gogh you can drive." But even higher praise is that he actually drives it, which is no mean feat considering what else he has in his garage, from cherished classics like a Ferrari 275 GTB and Jaguar XKSS to modern Zagato coachbuilt specials like the Alfa Romeo TZ3 and Ferrari 550 GTZ Barchetta.
