Watch these Dodge Demons explode on a Texas drag strip

The Dodge Challenger SRT Demon is extremely quick. It can hit 60 mph from a dead stop in less time than it takes to read this sentence thanks to its supercharged 6.2-liter V8. That engine makes up to 840 horsepower and 770 pound-feet of torque, depending on what octane is running through the fuel lines. That's a ton of power going solely to the rear wheels. So much so that Dodge developed a number of features and a new set of tires specifically for the car. In our time with the Demon, the car took abuse run after run on a drag strip without skipping a beat, but it seems some actual owners aren't quite so lucky. Just take a look at what happened to a few of these cars. You can see the whole car shake and jitter right as the whole rear explodes in front of the tree. It seems the initial shock from the launch — the most taxing bit of any drag run — is what kills the differentials. Catastrophic failure is rarely pretty, but it is neat to see the whole thing occur in slow motion. Three more cars — four stock and one modified in total — suffered similar fates. Not a great look for Dodge or SRT. According to The Drive, a private drag event in Texas drew a number of Demon owners all trying to beat NHRA NHRA Top Fuel racer Leah Pritchett's time in her personal Dodge Demon — 42 stock Demons attended along with five modified cars. While no one managed to match her 9.65-second quarter-mile run, a few owners did dip below 10 seconds. Now, there are a few of caveats we must address. First, with any modified car, you run the risk of breaking something, even with a car that's set up from stock specifically for drag strips. Even a set of tires like the Mickey Thompsons shown in the video above can have an effect on driveline components. Horsepower may be king, but it's torque that's the rear killer. All that torque sends a shock through the car. Adding even more with aftermarket parts increases the risk of something failing. The modified car was apparently pushing out about 1,000 horsepower. That said, four of the five vehicles were stock, so any extra power or torque should theoretically be a non-factor. The drag strip's surface was maintained by a company called Mass Traction. FCA used Mass Traction during the Demon's development, so that too should be a non-factor in the part's failure. It's unclear what exactly caused the failures, though The Drive reports that FCA officials are investigating the matter. Related Video: This content is hosted by a third party.

Chrysler expecting up to 200,000 9-speed transmissions for 3 models this year

Striving for improved fuel economy, we already knew that Chrysler will begin using a nine-speed automatic transmission in some of its new products this year, but what we haven't known is that volume at which this gearbox will be used. According to Bloomberg, Chrysler CEO Sergio Marchionne has been quoted as saying that the automaker expects to sell close to 200,000 units equipped with this new transmission in 2013. Those gear-rich trannies will be spread out across three models, consisting of the redesigned Chrysler 200, the still-unnamed Jeep Liberty replacement and the Dodge Dart.
This transmission should play a pivotal role in making Chrysler vehicles more competitive in their respective segments. Just for comparison, one of the Dart's key competitors, the Toyota Corolla, still uses a four-speed automatic, and a previous report indicates that the next-generation 200 could get up to 38 miles per gallon on the highway, which is better than most non-hybrid midsize sedans on the market. Marchionne says that the new Jeep model is expected during the second quarter of this year, but there is no word as to when the new 200 or nine-speed Dart will debut, but clearly Dodge would like to have the transmission in its compact yesterday. As for that volume figure, it definitely doesn't seem out of reach since the Dart, Liberty and 200 combined for a total of more than 225,000 units in 2012.
How many more gears can we expect in future cars? Probably not many more, since the CEO of transmission-builder ZF, Stefan Sommer, previously stated that nine speeds was the "natural limit" for transmissions.

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.
