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.

The Chrysler brand could be axed under Stellantis management

MILAN — While running NissanÂ’s North American operations from 2009 to 2011, Carlos Tavares had a reputation for closely watching costs with little tolerance for vehicles or ventures that didnÂ’t make money. Experts say that means Tavares, currently the head of PSA Group, is likely to follow that blueprint when he becomes leader of a merged PSA and Fiat Chrysler Automobiles. The low-performing Chrysler brand might get the axe as could slow-selling cars, SUVs or trucks that lack potential. Already the companies are talking about consolidating vehicle platforms — the underpinnings and powertrains — to save billions in engineering and manufacturing costs. That could mean job losses in Italy, Germany and Michigan as PSA Peugeot technology is integrated into North American and Italian vehicles. “You canÂ’t be cost efficient if you keep the entire scale of both companies,” said Karl Brauer, executive analyst for the iSeeCars.com auto website. “WeÂ’ve seen this show before, and weÂ’re going to see it again where they economize these platforms across continents, across multiple markets.” Shareholders of both companies are to meet Monday to vote on the merger to form the worldÂ’s fourth-largest automaker, to be called Stellantis. The deal received EU regulatory approval just before Christmas. Tavares, who for years has wanted to sell PSA vehicles in the U.S., wonÂ’t take full control of the merged companies until the end of January at the earliest. He likely will target Europe for consolidation first, because thatÂ’s where Fiat vehicles overlap extensively with PSAÂ’s, said IHS Markit Principal Auto Analyst Stephanie Brinley. Europe has been a money-loser for FCA, and factories in Italy are operating way below capacity — a concern for unions, given FiatÂ’s role as the largest private sector employer in the country. “We are at a crossroads,Â’Â’ said Michele De Palma of the FIOM CGIL metalworkersÂ’ union. “Either there is a relaunch, or there is a slow agonizing closure of industry, in particular the auto industry, in Italy.” ItalyÂ’s hopes lie with the luxury Maserati and sporty Alfa Romeo brands, but De Palma said investments are needed to bring hybrid and electric technology up to speed. FiatÂ’s Italian capacity stands at 1.5 million vehicles, but only a few hundred thousand are being produced each year. Most factories were on rolling short-term layoffs due to lack of demand, even before the pandemic.

2015 Dodge Challenger SRT Hellcat with '600-plus horsepower' officially unveiled [w/video]

Dodge has officially unveiled the most powerful vehicle to ever wear the Challenger name - the SRT Hellcat - complete with over 600 horsepower courtesy of a supercharged, 6.2-liter Hemi V8. It will be offered alongside the 485-hp Challenger SRT.
The new, force-induced V8 isn't just the most powerful ever fitted to the Challenger, it's the most powerful eight-cylinder Chrysler Group has ever built. Power figures aren't finalized, so expect to see "over 600 hp" bandied about quite a lot. That fury will be channeled through either a six-speed manual or eight-speed automatic. Yes, over 600 ponies through an eight-speed auto. So far, the only vehicle we know of that delivers more output through that many gears is the as-yet untested Chevrolet Corvette Z06. Sadly, we don't have performance metrics just yet, although if this thing can't crack four seconds to 60 miles per hour, we'll be pretty surprised.
As is the theme nowadays, the 2015 Challenger SRT features a number of driving modes, governing power output, shift speeds for the 8AT, steering effort, traction control settings and suspension settings. There are three pre-programmed options - Default, Sport and Track - and a Custom mode that allows drivers to mix and match to their heart's content.
