Dodge Demon makes so much torque, it needs stronger driveline parts

Torque is a lovely thing, a sweet and wonderful force that twists and pulls and can help propel a two-ton metal box forward at comical speeds. Torque is also fickle and will bend and break those same metal parts without a second thought, which is why the new Dodge Demon is compensating for its increased torque with some new re-engineered and reinforced parts. And there's software intended to combat wheel hop, which one of the most dramatic ways torque can break stuff. Week 8's video, "Race-hardened Parts," gives a hint towards what all these new parts can do. While we still don't know how much torque the Demon will throw out, we do know it's enough to warrant an upgraded prop shaft, half shafts, and a differential housing. The Challenger Hellcat, which is the basis for the Demon, makes 650 pound-feet of torque already. The new parts will go a long way toward making sure the work from the Demon's engine is properly translated into motion by those Nitto drag radials. The new prop shaft uses high-strength steel, heat-treated stub-shafts, and increases the tube thickness by 20 percent for a 15 percent increase in torque capacity. Additionally, Dodge says the upgraded differential housing allows for a 30 percent increase in torque capacity by using heat-treated A383 aluminum alloy and a higher strength shot-peened gear set. The 41-spline half shafts that deliver 20 percent increased torque capacity through the use of high-strength low alloy steel and 8-ball joints. In addition to the hardware, the Launch Assist software has been tuned to help alleviate wheel hop. Dodge says the Demon is the first factory production car that uses wheel speed sensors to detect hop and momentarily cut torque to compensate. This means a driver can keep their foot planted on the floor while the computer sorts out the traction. Previously, the best solution was to back off the throttle to manually cut the load. Finally, the Dodge Demon will offer a four-point harness mounting bar as an optional accessory. The part will be supplied by Speedlogix and fits in place of the deleted rear seat. Customers can install the bar without having to hack apart their cars to find a proper mounting point. Look for more teasers and info on ifyouknowyouknow.com in the lead-up to the Demon's debut at the 2017 New York Auto Show.

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.

Cars.com runs 11-second quarter with Dodge Charger Hellcat

The Dodge Charger SRT Hellcat and its Challenger sibling are two of the heroes of the modern performance world. With a headline-grabbing 707 horsepower from a supercharged 6.2-liter V8, their output even shames many supercars. But how quick can one really cover a quarter mile? Cars.com recently decided to find out by taking a Charger Hellcat to the drag strip to see if the sedan lived up to Dodge's 11-second claims. The results were quite impressive. After 13 quarter-mile runs of adjusting variables like the tire pressures and the car's various electronic aids, the Charger Hellcat managed a pass in 11.03 seconds at 126.61 mph – the pinnacle result of the day. This car was mechanically stock and wore the optional Pirelli P Zero tires. According to Cars.com, other quick sprints reached 11.09 seconds and 11.1 seconds, which even beat the site's 11.41-second best from a Challenger Hellcat last year. Getting the Hellcat's prodigious power down without losing traction was a challenge, even on the summer tires. Cars.com thought it had a run that could have dropped below 11 seconds, but then the wheels spun. Using the factory-recommended pressures, the Charger Hellcat was no still slouch with an 11.27-second time recorded, but taking things down to 25 psi proved the quickest at the strip. We already knew that the Charger Hellcat was a wonderful vehicle for eating up huge gulps of asphalt at high speeds and could verify its 204-mile-per-hour top speed (quite a bit faster, incidentally, than the Ferrari California T's 196 mph top-speed). Apparently, the 11-second quarter-mile claim is just as accurate. Also, for any curious owners, the Cars.com story divulges many of the tweaks required to reach this seriously quick time.
