Dodge Challenger SRT Demon TransBrake eliminates the need for brake torquing

Performing the perfect launch is key to drag racing. In order to get consistent starts, the engineers behind the Dodge Demon developed TransBrake, a system that holds the output shaft of the automatic transmission to keep the vehicle stationary until launch. Rather than the traditional method of two-foot brake torquing, the system is triggered by pulling the shift paddle for quick and consistent launches. According to Dodge, the main benefit of TransBrake versus a two-foot setup is a quicker power delivery and higher engine launch torque potential. The system gives brake-free launches up to 2,350 RPM, a 105-percent increase in launch boost pressures, and a 120-percent increase in engine launch torque. Dodge also claims that using the paddle provides a 30-percent better reaction when compared to using your feet. In addition to shifting duties from your feet to your hands, the Demon's TransBrake will preload the driveline. Torque is loaded at the wheels, not the transmission. That means full torque delivery 150 milliseconds after the shift paddle is released. It should also help reduce the driveline shock that occurs when those 315 section rear tires get near-instant grip. The reveal is coming near.

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.

Mustang, Camaro, Challenger gallop onto USPS pony car postage stamp set

Some of America's most iconic cars are about to be immortalized on postage stamps. A new set by the U.S. Postal Service will celebrate the the golden era of pony cars, featuring five classic examples of Detroit iron. Each one is beautifully illustrated in oil-on-canvas style, with subjects in motion and sunlight glinting off the chrome, and would add a nice touch to any first-class letter. The pony car segment was all about (relatively) small, sporty alternatives to the full-size land yachts of the 1960s. They typically came equipped with 6-cylinder engines or small-block V8s. The category was named after the Ford Mustang, hence  the name. Some, though, argue that the Plymouth Barracuda, which was launched a couple of weeks before the Mustang, is the first. Luckily, the Falcon-based Mustang's distinct styling generated a sales sensation, or we might be calling them fish cars. Appropriately, one of the featured cars is a Mustang. But it's not just any Mustang. The 1969 Boss 302, seen here resplendent in Bright Yellow, was created for the hotly-contested SCCA Trans-Am racing series. One of its main rivals would have been the 1969 Chevy Camaro Z/28, also created specifically for the series, and is included in the set in Fathom Green. Representing Auburn Hills in the set is a 1970 Dodge Challenger R/T in Plum Crazy, while Southfield's American Motors gets a nod with an AMC Javelin in Big Bad Orange. The Mustang's platform cousin, a 1967 Mercury Cougar XR-7, is portrayed in a gorgeous Burgundy Poly that almost looks incomplete without Neko Case on the hood. It's not the first time the USPS has honored America's rich car culture on its stamps. In 2013, it issues a series of muscle car stamps with the help of Richard Petty. That set featured a 1966 Pontiac GTO, 1967 Shelby GT-500, 1970 Chevelle SS, 1970 Plymouth Hemi ’Cuda and, of course, a 1969 Dodge Charger Daytona. Another set in 2016 featured classic pickup trucks. Going further back, a 2008 release had chroed and finned automobiles of the 1950s and a 2005 release featured sporty American cars of the same era. The pony car stamps will debut on August 25 at the Great American Stamp Show in Sacramento, California in partnership with the American Philatelic Society. The public is free to attend the dedication ceremony, but you must RSVP first. After that, they will be available at local post offices and on line at the USPS store.
