The Dodge Demon's massive torque wrinkles its massive tires

Horsepower doesn't mean a damn thing if a car can't properly put the power down. That's why Dodge has fitted the upcoming Demon with some of the stickiest road-legal rubber available. Those Demon-branded Nitto NT05R drag radials skirt by regulations with just the smallest of margins, and in order to maximize the potential of the 315/40R 18 size tires Dodge increased the car's torque multiplication with a higher stall speed for the torque converter and a 3.09 rear axle. The 12.6-inch-wide tires are fitted to 18x11-inch wheels at all four corners, and they're fatter than those 305-section front tires on the Camaro Z/28 that we raved about years ago. Dodge says the combination of soft, gooey rubber and the new gear ratio gives the Demon about a 15 percent larger tire contact patch, more than twice as much grip, and roughly an 18 percent increase in both converter torque and rear-axle torque multiplication. Simply put, the Dodge Demon moves. You can see the results in the teaser video above, which is titles "Multiplication" and shows the crazy wrinkling of the sidewall that results from putting that torque to the road. We wouldn't be surprised if the inner rim of the wheel needs some grip to keep the tire seated, something Chevy had to do on the last Z/28. There is something wonderful about Dodge's approach to performance cars. While the Ford Mustang and Chevrolet Camaro have moved on from their muscle car upbringings with proper track-focused models, Dodge has stayed true to its roots by developing a machine that's sole intent is traveling a quarter-mile quicker than anything else on the road. Twisty roads may be fun, but there is something wholly and deeply satisfying about going deep into the accelerator with a comical amount of power at your disposal. We can't wait.

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.

Dodge Durango gets performance Mopar options for R/T, SRT

Fiat Chrysler is showing new performance add-ons for the 2018 Dodge Durango R/T and SRT models at the Chicago Auto Show, including the familiar Dodge dual center stripes and a new Mopar exhaust system. The 475-horsepower SRT model, which is powered by a 6.4-liter Hemi V8, will also offer a lowering spring kit and a carbon-fiber instrument panel. The signature two-stripe treatment blankets the three-row SUV from the front to rear fascia and is tailored to the signature NACA duct-hood vent. It'll come in five different colors — bright blue, flame red, gunmetal low gloss (metallic finish), low-gloss black and sterling silver — and retail for $1,195 starting in March. View 7 Photos Mopar developed its new bolt-on performance exhaust systems with Dodge SRT engineers and designers to improve flow and achieve that sweet sound. It features a chromium 304 stainless steel construction to make it more resistant to corrosion, with stainless steel band-style clamps and welded and polished 4-inch tips. It costs $1,595 for the Durango R/T and is available now. On the SRT, the price goes up to $1,850, with the package available in the second quarter. New Mopar springs improve the Durango SRT's high-speed cornering stability and consistency by lowering the SUV an average of 15 millimeters, or 0.6 inches. They were developed with proprietary Dodge SRT data not available to the aftermarket to tune the lowering springs to the factory dampers, giving the vehicle less rear-end squat during acceleration, less nose dive while braking and reduced body roll on corners. MSRP on the package, which is available now, is $325. For just under $2,500 you can get the SRT Interior Appearance Group package, which adds a premium-wrapped carbon-fiber instrument panel and door bezels, Dinamica soft-touch headliner and accent paint on speaker trim rings. The Chicago Auto Show is open to the public Feb. 10-19.
