Dodge Viper to out-Hell the Hellcat with supercharged V10?

The Viper wouldn't be the Viper if it wasn't the most powerful model under the Chrysler umbrella. But with the arrival of the Hellcat engine in the Dodge Charger and Challenger, the Viper has fallen behind in the bragging rights department: where the new supercharged V8 produces 707 horsepower and 650 pound-feet of torque, the naturally aspirated V10 offers "only" 640 hp and 600 lb-ft - gargantuan output figures by almost any other standard, but crucially behind on the SRT power scale. Conner Avenue is going to have to do something about that.
Although the Hellcat's engine reportedly won't fit under the Viper's hood, SRT is now rumored to have another trick up its sleeve: supercharge the existing V10. According to the Pentastar performance enthusiasts at allpar.com, Chrysler has already taken delivery of the first such prototype engines so that it can begin the process of fitting it into an upgraded Viper.
The spooled ten-pot is tipped to produce around 800 hp and 650 lb-ft of torque. More than that and the Viper's drivetrain, chassis and bodywork would have to be substantially reworked. Though beefier transmissions are available, fitting them would reportedly set off a domino-game of changes required to handle the added torque. Which may be something Chrysler would be prepared to do for the next-generation model, but in the meantime, 800 hp could prove enough to put the Viper back atop the Mopar performance ladder where it belongs, and give it an edge against the new Corvette Z06 to rekindle sales.

Cold start comparison: 2020 Alfa Romeo Giulia Quadrifoglio vs. 2013 Dodge Challenger SRT8

The 2020 Alfa Romeo Giulia Quadrifoglio is a five-seat, compact luxury sport sedan packing 505 horsepower thanks to a 2.9-liter twin-turbocharged V6. My personal 2013 Dodge Challenger SRT8 392 is ... well ... not. It's a full-sized muscle coupe whose iron-block 6.4-liter V8 makes 470 hp in the very traditional way: it's freakin' huge, like everything else about the car.  On paper, these two have nothing in common beyond the fact that they were built by the same multi-national manufacturing entity.  But if paper were the be-all and end-all of automotive rankings, everybody would buy the same car. And we don't, especially as enthusiasts. Whether it's looks or tuning or vague "intangibles" or something as simple as the way a car sounds, we often put a priority on the things that trigger our emotions rather than setting out to simply buy whatever the "best" car is at that particular moment.  So, what do these two have in common? They both sound really, really good. Like looks, sounds are subjective. While a rubric most assuredly exists in the world of marketing (attraction is as much a science as any other human response), we have no way of objectively scoring the beauty of either of these cars, and the same applies to the qualities of the sound waves being emitted through their tail pipes.  But we can measure how loud they are. In fact, there's even an app for that. Dozens, as it turns out. So, I picked one at random that recorded peak loudness levels, and set off to conduct an entirely pointless and only vaguely scientific experiment with the two cars that happened to be in my garage at the same time.  For the test, I opened up a window and cracked the garage door (so as not to inflict carbon monoxide poisoning upon myself in the name of discovery), and then placed my phone on a tripod behind the center of each car's trunk lid. I fired each one up and let the app do the rest. I then placed my GoPro on top of the trunk for each test so that I could review the video afterward for any anomalies.  I started with the Challenger. The 6.4-liter Hemi under the hood of this big coupe is essentially the same lump found under the hood of quite a few Ram pickups, and it has the accessories to prove it. Its starter is loud and distinctive. Almost as loud, it turns out, as the exhaust itself. As its loud pew-pew faded behind the V8's barking cold start, we recorded a peak of 83.7 decibels. In the app's judgment, that's roughly the equivalent of a busy street.

Gas prices down, 707-hp engine production up... USA!

On Saturday, the United States of America will celebrate its 239th birthday. That means fireworks, barbecues, block parties, and, oh yeah, Hellcat engines and low fuel prices. The most American of (Mexican-built) powerplants, the big, loud, supercharged, 707-horsepower Hemi is slated for yet another production boost to match up with some serious demand, while the dino juice it runs on is cheaper than it's been in over half a decade. The Saltillo, Mexico engine factory already produces some 4,000 Hellcat engines each year – that's in addition to the Tigershark four-cylinder, the 5.7-liter Hemi, and 6.4-liter SRT Hemi V8s – and it's not entirely clear how many more might get added to that total. What we do know, though, is that Fiat Chrysler can't build the engines fast enough. "We're going to build more [Hellcats] for 2016," SRT boss Tim Kuniskis told Automotive News. "It's a small sliver of what we sell, but it really creates a halo for the rest of the lineup. For example, the next highest car, the Scat Pack Challenger, I have essentially a zero-day supply. It's sold out." This bit of good news comes on the back of something equally good – low summer gas prices. According to the US Energy Information Administration, the nationwide average for for "all formulations" of fuel in June sits at $2.885. Ignoring the remarkably low prices we saw in January and February of this year – figures that themselves hadn't been seen since May of 2009 – the national average hasn't sat that low since October 2010. So yes, it's a very a good time to be an American gearhead.
