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.

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.

Chrysler says its 8-speed transmissions will save 700 million gallons

Chrysler Group's TorqueFlite eight-speed transmission could be earning some serious green bragging rights if the company's projections are correct. The recently widely proliferated automatic gearbox, which is now in more than a million vehicles around the world, is poised to save drivers an estimated 700+ million gallons of fuel over the vehicles' lifetimes (an expected cost savings of $2.5 billion). In addition, Chrysler expects a reduction in CO2 emissions by more than six million metric tons. According to Chrysler, and depending on the vehicle, the TorqueFlite can improve fuel economy. The TorqueFlite autobox features particularly close ratios from fifth to eighth gear (see the press release below for the specific numbers), and uses low-viscosity fluid that doesn't need to be replaced. Transmission software adapts to the driving situation to optimize efficiency based on driver behavior, temperature, grade, stability control, and longitudinal and lateral acceleration. The TorqueFlite is capable of handling a variety of duties. As evidenced by the wide range of vehicles Chrysler Group has seen fit to equip with the eight-speed transmission, the TorqueFlite is capable of handling a variety of duties. Since its 2012 introduction, the TorqueFlite has gone from performing cog-swapping duties in Dodge Charger and Chrysler 300 models equipped with the 3.6-liter Pentastar V6 to changing gears in vehicles such as the Pentastar- and Hemi-powered Dodge Durango, Jeep Grand Cherokee and even the Ram 1500 EcoDiesel. For the 2015 model year, the eight-speed is finding its way into even more vehicles with the addition of a third version. In addition to the American-made TorqueFlite 845RE and 8HP70, the new 8HP90 will be manufactured in Saarbrucken, Germany. The 8HP90 is designed for higher torque loads, making it ideal for high-performance vehicles like the 2015 Dodge Challenger SRT Hellcat. The already-in-use 8HP70 will expand its duties to be used in 2015 Hemi models such as the Dodge Charger, Challenger, and Challenger SRT8. You can see the list of those benchmarks in Chrysler's press release below.
