Stellantis reveals STLA Large platform with EV and ICE support

Hot on the heels of a Jeep Wagoneer S teaser and photos of the prototype next-generation Dodge Charger (or Challenger), comes a reveal and details of what will likely underpin both of them: the STLA Large platform. It's one of multiple Stellantis flexible architectures that will be the basis of its upcoming electric cars, and apparently internal combustion ones, too. Stellantis says the STLA Large platform will be for D- and E-segment cars, crossovers and SUVs. In other words, it will be for midsize and large vehicles. For reference, lengths supported will be from 187.6 to 201.8 inches, and width will range from 74.7 to 79.9 inches. It will be highly flexible, too, with Stellantis claiming significant amounts of adjustability in overhangs, wheelbase, suspension placement and powertrain arrangement. The powertrain flexibility is quite impressive. Front-, rear- and all-wheel-drive layouts will be supported. Single- and dual-motor layouts will be on offer. Internal combustion will be available, too, either on its own or as a hybrid. Apparently engines can be fitted either longitudinally or transversely, too. Battery packs with between 85 and 118 kWh of capacity will be offered, with Stellantis claiming that sedan-style vehicles could have a range of up to 500 miles. The packs will also be available in 400- and 800-volt designs. Stellantis noted also that the platform can "easily accept future energy storage technologies when they reach production readiness." This seems to hint that the company is looking at different battery chemistries and maybe even solid-state batteries that could be added more easily in the future. Furthermore, the platform is designed to handle impressive output. Stellantis says that some models on the platform will have 0-to-62 mph times in the 2-second range. Limited-slip differentials for improved power delivery and wheel-end disconnects for reduced mechanical drag are also on the table for this platform. All of these details fit well with the information previously given for the concept Dodge Charger Daytona Banshee and Jeep Wagoneer S. The former was previewed with both battery voltage architectures and a wide range of electric powertrains with between 456 and 670 horsepower depending on specification and upgrades. And that's just for the 400-volt system; the 800-volt option wasn't detailed. We've also seen photos of the Charger chassis seemingly with provisions for gas engines, likely versions of the Hurricane I6.

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.

2015 Dodge Challenger crash test results slip from last year's model

The National Highway Traffic Safety Administration has released the results of its latest round of crash testing, announcing that the 2015 Dodge Challenger has netted a five-star overall crash rating. Of course, Chrysler won't want us to tell you this, but that NHTSA overall rating is not the whole story here. As The Car Connection so astutely points out, five-star rating aside, the refreshed 2015 Challenger actually performed worse than when it was tested back in 2013. The V6-powered SXT model tested by NHTSA in this latest round of testing was only able to record a four-star rating in its frontal crash test, while it nailed a five-star rating in the side-impact test. The 2013 Challenger managed a five-star rating in the frontal test. Of course, while this rating is a sign of overall good news for Challenger fans, the car, as TCC argues, has yet to be tested by the Insurance Institute for Highway Safety. It'll be interesting to see if these NHTSA ratings translate to an IIHS Top Safety Pick or Top Safety Pick Plus. Scroll down for the full press release from FCA. All-new 2015 Dodge Challenger Earns Five-Star Overall Safety Rating From U.S. National Highway Traffic Safety Administration 2015 Dodge Challenger coupe earns five stars overall, the highest possible score in NHTSA's safety rating program More than 70 safety and security features, including new for 2015 class-exclusive Forward Collision Warning, adaptive cruise control, Blind-spot Monitoring and Rear Cross Path detection All-new 2015 Dodge Challenger starts at $26,995 (excluding tax, destination and title) December 18, 2014 , Auburn Hills, Mich. - The all-new 2015 Dodge Challenger has earned a five-star overall safety rating from the U.S. National Highway Traffic Safety Administration (NHTSA). Five stars is the highest possible safety rating given by NHTSA. "The new Dodge Challenger coupe further demonstrates our commitment to broaden the proliferation of advanced safety technologies, such as driver-assist features," says Scott Kunselman, Senior Vice President-Vehicle Safety and Regulatory, FCA-North America. In its assessment of the new Challenger, NHTSA notes the availability of Forward Collision Warning (FCW), which features forward-facing sensors programmed to detect the potential for certain types of frontal collisions. If detected, the driver is alerted with visual and audible warnings. The 2015 Dodge Challenger is the only car in its segment with such capability.
