Hennessey's Dodge Challenger Hellcat cranks out 1,032 hp

Enthusiasts know the Dodge Challenger Hellcat produces 707 horsepower. It's one of the modern muscle-car era's iconic numbers. But for some, that's not enough. Enter Hennessey Performance. The Texas tuners loaded the Hellcat with a twin-turbocharger that works with Dodge's supercharger to boost output to 1,032 hp and 987 pound-feet of torque. Yes, that's an engine dyno rating, not at the rear wheels, but still! It's a little more complicated than a bolt-on booster. Called the HPE1000, the turbo kit has stainless steel headers and down pipes, billet aluminum compressor wheels, and a high-flow air system. There's also an an improved fuel pump, and the engine and chassis are specially calibrated. You also get numbered plaques signed by John Hennessey himself and the engine tech who builds your mill. All of this helps get your Hellcat to 60 miles per hour in 2.7 seconds, and it can do the quarter mile in 9.9 seconds at 142 mph. The Hellcat and it's 6.2-liter blown Hemi V8 are not for the faint of heart. Hennessey makes this Dodge downright demonic.

Are supercars becoming less special?

There's little doubt that we are currently enjoying the golden age of automotive performance. Dozens of different models on sale today make over 500 horsepower, and seven boast output in excess of 700 hp. Not long ago, that kind of capability was exclusive to supercars – vehicles whose rarity, performance focus, and requisite expense made them aspirational objects of desire to us mortals. But more than that, supercars have historically offered a unique driving experience, one which was bespoke to a particular model and could not be replicated elsewhere. But in recent years, even the low-volume players have been forced to find the efficiencies and economies of scale that formerly hadn't been a concern for them, and in turn the concept of the supercar as a unique entity unto itself is fading fast. The blame doesn't fall on one particular manufacturer nor a specific production technique. Instead, it's a confluence of different factors that are chipping away at the distinction of these vehicles. It's not all bad news – Lamborghini's platform sharing with Audi for the Gallardo and the R8 yielded a raging bull that was more reliable and easier to live with on a day-to-day basis, and as a result it went on to become the best-selling Lambo in the company's history. But it also came at the cost of some of the Italian's exclusivity when eerily familiar sights and sounds suddenly became available wearing an Audi badge. Even low-volume players have been forced to find economies of scale. Much of this comes out of necessity, of course. Aston Martin's recent deal with Mercedes-AMG points toward German hardware going under the hood and into the cabin of the upcoming DB11, and it's safe to assume that this was not a decision made lightly by the Brits, as the brand has built a reputation for the bespoke craftsmanship of its vehicles. There's little doubt that the DB11 will be a fine automobile, but the move does jeopardize some of the characteristic "specialness" that Astons are known for. Yet the world is certainly better off with new Aston Martins spliced with DNA from Mercedes-AMG rather than no new Astons at all, and the costs of developing cutting-edge drivetrains and user interfaces is a burden that's becoming increasingly difficult for smaller manufacturers to bear. Even Ferrari is poised to make some dramatic changes in the way it designs cars.

Demon's NHRA competition ban: Good talking point, bad feature

One of the biggest headlines for the Dodge Challenger Demon is that, in stock form, it's so fast that the NHRA won't allow it to compete in the organization's events. It's the ultimate humble brag, "I can't drag race my car because it's so fast it was banned by the sanctioning body." Certainly Tim Kuniskis, head of FCA brands in North America, was excited. He told the press that he hugged the guy that brought him the letter banning the Demon from competition. Unfortunately, the reality is that not being NHRA-legal is kind of silly, and frustrating for owners who would want to actually race. Before we go too much farther, we should explain exactly why the Demon is illegal for NHRA competition. The car is capable of a sub-10-second quarter-mile time both on racing fuel and 91-octane pump gas. Cars that fast are required by the NHRA to have a full, certified roll cage, and the Demon doesn't. Now there are certainly ways to get around this. The most obvious would be for a Demon owner to have a company install a roll cage. Using less grippy tires than the barely street-legal Nitto cheater slicks would probably help bring that time down, too. There's also the option of putting the car into Eco mode, and, yes, the Demon has one. In Eco mode, the Demon makes just 500 horsepower, and trips the lights at the quarter-mile in 11.59 seconds, which will avoid the roll-cage requirement. However, none of these options are ideal. For one thing, if you bought an 840-horsepower car, you're not going to want to limit it when you get to a closed course such as a drag strip. Similarly, you're not going to want to ditch your super-sticky tires at the strip, especially when they're standard equipment. Finally, having to go aftermarket for a roll cage is an inconvenience at minimum, and it seems like a strange oversight considering the rest of the car. This is a car from the factory that comes with drag radials, no passenger seats, a racing fuel tune, air conditioned intercooler, and even skinny front wheels for drag racing. Its purpose is clear, but for some reason, Dodge stopped short of giving it a roll cage that would allow it to compete. Perhaps adding a roll cage would've made it difficult to pass safety regulations, and we would be more disappointed if the car wasn't allowed on the street. Even so, it seems like an odd stopping point.
