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.

Jeep Wrangler 4xe's hybrid powertrain: Could it be headed to other FCA products?

On its own, the 2021 Jeep Wrangler 4xe plug-in hybrid is a big deal for the brand and the model line. It's the most powerful and most efficient Wrangler by significant margins, and it doesn't give up the off-road capability that makes the Wrangler so special. But another great thing about this hybrid powertrain is its potential to be transplanted into other FCA vehicles. Just to recap, the layout of the Wrangler's hybrid powertrain, front to back, is as follows: engine, clutch, electric motor, clutch, transmission. The engine is the same 2.0-liter turbocharged four-cylinder that's a standalone engine for the Wrangler. The transmission and electric motor are sort of one unit, with the motor and clutch replacing the torque converter of the transmission. And the transmission itself is the ubiquitous eight-speed ZF automatic gearbox. Its transmission code name is 8HP75PH. The ZF eight-speed is available in every FCA product with a longitudinally-mounted engine and rear-wheel drive or four-wheel drive, with variations in the amount of power and torque it can handle. Not only that, but the Ram 1500 and 2500 and the Jeep Wrangler and Gladiator all have powertrains that utilize the non-hybrid version of the 8HP75 transmission specifically. Even the gear ratios for that transmission as well as the 8HP70 used in the Jeep Grand Cherokee, Dodge Durango, Dodge Charger and Chrysler 300 are nearly identical to those in the 8HP75PH. And a Fiat-Chrysler representative confirmed that the transmission portion of the hybrid drivetrain is basically carry-over from the regular 8HP75. So a transplant could be a relatively simple process. As for which of these models would be the most likely to receive the hybrid powertrain first, the Jeep Gladiator and Ram 1500 would seem like good bets, since they likely have the most similar transmissions, and the Gladiator in particular because of its closely-related underpinnings to the Wrangler. Both are also highly profitable trucks that sell well and could justify the development costs of adapting another powertrain. And in the case of the Ram, there's the impending F-150 hybrid to think about. Although Ram isn't going after a fully electric model, a PHEV could be a nice middle ground. A potential limiting factor would be whether the hybrid powertrain would be sufficiently robust to handle heavy payload and towing demands, particularly over longer periods.

2018 Dodge Challenger GT Drivers' Notes Review | The right car for the season

Associate Editor Joel Stocksdale: Dodge uses the Challenger GT trim to denote its V6 all-wheel-drive model, but it seems apt for reasons besides that. The Challenger, even with a V6, is an excellent, affordable American grand tourer. It's still extremely stylish, despite barely changing looks since Dodge introduced it for the 2008 model year. The solid gray on this one was particularly attractive. It also seemed appropriate considering the Challenger's battleship size. This thing is truly massive. That's beneficial in the sense that it has an enormous trunk (perfect for touring), but not so much for maneuvering. But thankfully, it's easy to spot the corners, which helps a lot. The Challenger GT is a pretty able handler, too. It feels composed in corners, not too heavy, only mild body roll, and steering that weights up very naturally. The ride is relatively comfortable. It takes the edge off of most pavement imperfections, but you feel more than you might expect. So the Dodge Challenger GT has the style, space, and a decent balance of sportiness and comfort — which just leaves one thing left to address, the powertrain. And as it turns out, the V6 actually works quite nicely in the big Dodge. Under full throttle, you get an angry, throaty honk from the intake that, while not as smooth and classic as a V8, is still fairly satisfying. It also has more than adequate acceleration, if not exhilarating. It's a combo that makes not only a fun affordable GT car, but just a solid commuter with an extra dose of style. The only caveat is that if you need something more truly sporty, you may still want to look at a Camaro or Mustang. Associate Editor Reese Counts: I spent the latter half of last week in Idaho and Wyoming driving a pretty sweet Nissan 370Z in the snow. That car was equipped with tracks and skis and allowed me to do some pretty dumb things with few repercussions, though it was one of the loudest and most uncomfortable cars I've ever driven. Coming home to Detroit and a Destroyer Grey Challenger GT was a very nice change of pace. The thing is, this car is still plenty capable in the snow. I like the Challenger quite a bit, especially in the bonkers Hellcat and Demon guise. But not everyone needs a 700-plus horsepower brute that guzzles gas with a nearly unequalled thirst. The Challenger GT checks a lot of boxes. It looks good, it's comfortable, roomy and thanks to all-wheel drive, genuinely usable year round.
