Subaru Legacy pitted against Roadkill project cars

There's an evergreen debate among auto enthusiasts about whether they would prefer to have the latest and greatest car of today or a certified classic from yesteryear. What if you had to further define that, though, and the choice was between a brand new 2015 Subaru Legacy or a turbocharged Datsun 240Z with a hatch that wouldn't close? Roadkill aimed to find out that and more in one of its best videos to date.
According to the hosts, Subaru came to them, handed over some money and challenged Roadkill's project cars against its latest Legacy. The result is every bit as good (or better) than any automotive-themed show you could find on television.
Things start simple with a figure-eight race in a rodeo arena with the Subaru taking on Roadkill's 1968 Ford Ranchero, originally built for ice racing. From there the Legacy races a 1968 Dodge Charger with no windows around and off-road rally stage. Finally, the Subie goes head-to-head against the Rotsun, the aforementioned turbocharged 240Z, through an abandoned neighborhood. Plus, there's a bonus drag race challenging them all.

2016 Dodge Viper ACR is ready to take a bite out of the Corvette Z06 [w/video]

The Dodge Viper ACR is back, and as Fiat Chrysler Automobiles tells it, it's the most venomous breed ever born. Before you get too excited, the 8.4-liter V10 produces 645 horsepower; five more than the standard Viper and five less than the supercharged Chevrolet Corvette Z06. It's unclear why Dodge didn't extract more from the huge engine, although we somehow imagine that certain people in Maranello, Italy had a say in the matter. Instead of blessing the ACR variant with bunches of extra output, Dodge instead turned to an aggressive aerodynamics package that it claims delivers nearly a ton of downforce at the Viper's maximum speed of 177 miles per hour. The total aero package includes an adjustable, twin-element, carbon-fiber rear wing, carbon-fiber diffuser, an extendable front splitter, and dive planes. Those big louvers on the hood? Yeah, they're removable, too. The "race-tuned" suspension uses coil-over Bilstein shocks that offer ten different settings and up to three inches of height adjustment. Kumho Ecsta V720 tires were built specifically for the Viper ACR, and come in 355/30 in back and 295/25 in front, with 19-inch wheels at all four corners. Along with the aero improvements, Dodge is claiming the Viper can pull a race-car-like 1.5Gs in higher-speed turns. Carbon-ceramic brakes with six-piston calipers add the stopping power that's greater or equal to the ACR's cornering performance. Dodge was also keen to reduce weight, taking some rather dramatic measures in the effort. The stereo has just three speakers, while the electric function was removed from the seats. Even the carpet has been replaced with a "lightweight" alternative. Finally, Dodge is offering up the innovative 1 of 1 customization it pioneered with the Viper GT earlier this year. That means that not only can you get the fastest Viper ever built, but it'll be entirely your own when you take delivery.

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.
