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.

Stellantis launching at least 25 EVs for America by 2030

Stellantis has announced a wide-ranging plan for the company through 2030 covering everything from product to financials. The product plans are what really caught our attention, particularly for the surprise reveal of the first electric Jeep, as well as new teasers of the electric Ram 1500. But the company also provided more broad details on what we'll be seeing in the future including both electric cars and hydrogen fuel cell vehicles. All of the plans are in service of the Stellantis goal of reaching net zero carbon emissions by 2038. On that way, it plans for all European vehicle sales and half of all American sales to be electric by 2030. It will launch 75 new electric vehicles by that year, and at least 25 of them will be coming to the U.S. The first of those electric cars will be the aforementioned Jeep in 2023, but many Stellantis models will follow close behind. The electric Ram ProMaster will launch in 2023 as well. In 2024, we'll see the electric Ram (and its plug-in hybrid counterpart), two more Jeeps (an off-road model and a family-oriented model) and the Dodge electric muscle car. We'll get a preview of the Dodge with a concept this year. Then in 2025, Chrysler will launch its electric car, likely based on the Airflow concept. Stellantis has previously announced Chrysler will be fully electric by 2028, and it further announced that Alfa Romeo and Maserati will be fully electric by 2030. Stellantis is also working on hydrogen fuel cell vehicles, mainly for commercial use. For the U.S., it plans on offering a large, ProMaster-size hydrogen van in 2025. That year or a little later, it also has plans for a hydrogen heavy-duty pickup truck, presumably Ram 2500 and 3500. Stellantis CEO Carlos Tavares noted that among the benefits of hydrogen for large and commercial vehicles is being able to avoid compromising payload capacity, since hydrogen powertrains are lighter than giant batteries. Hydrogen filling times are quick relative to charging, too. The company will continue working on and offering advanced driver aids. This year it will offer hands-free cruise control like GM's Super Cruise and Ford's BlueCruise. In 2024, the company intends to introduce a system that is hands-free and won't require the driver to be watching it the entire time. The technology is being developed alongside BMW. These are, of course, broad plans, and they could change as time goes on. Expect more details as we get closer to individual product releases.

2015 Dodge Viper getting small increase in power

The Viper is used to being the most powerful car in the Dodge and SRT stables, but the arrival of the 2015 Dodge Challenger SRT Hellcat means that's no longer the case. The serpentine supercar is, however, reportedly getting a small boost in output for 2015, amounting to all of five horsepower.
The increase was uncovered by Road & Track courtesy of the SAE J1349 certification process to which Detroit's Big Three automakers submit themselves and which reports the Viper's output at 645 hp instead of the 640 it was rated at until now. There are a hundred factors that could have contributed to the relatively mild boost in output (best guess? nothing at all changed...), but we doubt anyone's going to complain about some extra horses under the hood.
The five-horsepower boost brings the Viper that much closer to the 650-hp Chevy Corvette Z06, not to mention the 707-hp Hellcat, but the Viper's impressive power-to-weight ratio ought to mean it'll have little problem keeping up in a straight line - which is just one of the reasons why Chrysler won't shoe-horn the Hellcat into the Viper: as R&T points out, the supercharged engine is too heavy and the blower makes it too tall to fit in the Viper's engine bay.
