Watch the Dodge Charger SRT Hellcat verify its 204-mph top speed

The industry is producing some ridiculously fast four-doors these days, from the Porsche Panamera and Maserati Quattroporte to the Mercedes E63 AMG and BMW M5. But the fastest of them all doesn't cost six figures. It doesn't even come from Europe. It's made right here in North America, by a US automaker. And it starts at under $64k. We're talking about the Dodge Charger SRT Hellcat, the Pentastar muscle sedan with the 6.2-liter supercharged V8 and its 707 horsepower. Dodge claims it's the "quickest, fastest, most powerful [production] sedan ever," and they're not just blowing smoke... or smoking tires. During the final stages of development, engineers from Auburn Hills took a bone-stock, Hellcat-powered Charger out to a seven-mile oval for a top speed run and they filmed the occasion for posterity. The result? 206.9 miles per hour with the wind, 202.2 against it, for a two-way average top speed of 204.55 mph. Chew on that, imports.

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.

Watch dual-engined Dodge SRT4 do a FWD burnout, a RWD burnout, then AWD launch

There's something fantastically insane about racers who go out on their own and build something unique. Just take this crazy video from last year of a twin-engine Dodge SRT4 at a drag strip that can burn the rubber at either end – or both ends – at a moment's notice. With tires sticking out way past the fenders, a massive cooling system at the front and no back window to speak of, this Dodge is clearly meant solely for speed. Though it's real party trick is being able to spin the front or rear wheels independently. The setup makes for three quite showy burnouts. When it came time to actually get down the track, things got somewhat awkward. Like other twin-engine creations we've seen, the separate powertrains make for some odd sounds and a weird look launching down the strip. Still, there's no doubt that the engineering behind this Frankenstein is very impressive. Scroll down to see this monster in action and another of it in a very mismatched race last year.
