Watch a Dodge Challenger Demon break 200 mph

We all know that the Dodge Challenger Demon is a monster in short bursts. Its 840 horsepower and drag-ready tires allow it to hit 60 mph in a claimed 2.3 seconds on the way to a sub-10-second quarter-mile time. But it turns out that the Demon doesn't run out of grunt after the quarter-mile. This was proven by a group that took one to the runway where space shuttles landed, Johnny Bohmer Proving Grounds in Florida. There they hit a top speed of 203 mph. Dodge doesn't give a top speed for the Demon, but for a bit of comparison, the 707-horsepower Hellcat Widebody has a top speed of 199 mph. Watching the video, it's interesting how calm things appear to be in the cabin. There doesn't appear to be much vibration, and the car was clearly staying steady in a straight line, since the driver hardly moved the wheel. And before you know it, the 2.3-mile run is over. The run's not official unless a record-keeping body is witnessing it, and there will surely be Demons out there trying to beat this run, but it's sure fun to watch in the meantime.

2015 Dodge Challenger SRT Hellcat has 707 glorious horsepower [w/video]

Hold onto your butts. "600-plus horsepower" is what we were told to expect from the 2015 Dodge Challenger SRT with its 6.2-liter supercharged Hellcat V8 engine. But as we've just learned, those were incredibly conservative numbers. Dodge has officially announced that the range-topping Challenger will hit the asphalt with 707 - seven hundred and seven - horsepower, making it the "most powerful muscle car ever."
Of course, 707 hp is only part of the story, as the Hellcat has also been confirmed to produce 650 pound-feet of torque. All that power will run exclusively to the rear wheels through an eight-speed automatic transmission that differs from other Challengers. The new gearbox, 8HP90 (rather than the 8HP70) is "upgraded to handle the extra power and torque," says Dan Reid, SRT's manager of product design and motorsports.
We certainly hope you're prepared to spend a ton of money replacing tires.

Brand new cars are being sold with defective Takata airbags

If you just bought a 2016 Audi TT, 2017 Audi R8, 2016–17 Mitsubishi i-MiEV, or 2016 Volkswagen CC, we have some unsettling news for you. A report provided to a US Senate committee that oversees the US National Highway Traffic Safety Administration (NHTSA) and reported on by Automotive News claims these vehicles were sold with defective Takata airbags. And it gets worse. Toyota and FCA are called out in the report for continuing to build vehicles that will need to be recalled down the line for the same issue. That's not all. The report also states that of the airbags that have been replaced already in the Takata recall campaign, 2.1 million will need to eventually be replaced again. They don't have the drying agent that prevents the degradation of the ammonium nitrate, which can lead to explosions that can destroy the airbag housing and propel metal fragments at occupants. So these airbags are out there already. We're not done yet. There's also a stockpile of about 580,000 airbags waiting to be installed in cars coming in to have their defective airbags replaced. These 580k airbags also don't have the drying agent. They'll need to be replaced down the road, too. A new vehicle with a defective Takata airbag should be safe to drive, but that margin of safety decreases with time. If all this has you spinning around in a frustrated, agitated mess, there's a silver lining that is better than it sounds. So take a breath, run your fingers through your hair, and read on. Our best evidence right now demonstrates that defective Takata airbags – those without the drying agent that prevents humidity from degrading the ammonium nitrate propellant – aren't dangerous yet. It takes a long period of time combined with high humidity for them to reach the point where they can rupture their housing and cause serious injury. It's a matter of years, not days. So a new vehicle with a defective Takata airbag should be safe to drive, but that margin of safety decreases with time – and six years seems to be about as early as the degradation happens in the worst possible scenario. All this is small comfort for the millions of people who just realized their brand-new car has a time bomb installed in the wheel or dashboard, or the owners who waited patiently to have their airbags replaced only to discover that the new airbag is probably defective in the same way (although newer and safer!) as the old one.
