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.

Watch Atieva's electric van outrun a BMW i8 and Dodge Viper

A little while back, automotive startup Atieva drag raced its electric van, called Edna, against a Tesla Model S and a Ferrari California in order to compare its performance against known and revered mechanical athletes. Again, the Silicon Valley-based company is putting its prototype up against electrified and conventionally powered performance vehicles on the drag strip. Last time around, Edna, the Mercedes-Benz Vito van equipped with a 900-horsepower, all-wheel-drive powertrain, bested both of its foes. In that showcase, Edna was hitting 60 mph in a little over three seconds. Comparatively, BMW lists the i8's 0-60 time at 4.2 seconds, though Road & Track clocked it at 3.8 seconds, with a quarter-mile time of 12.3 seconds. The Viper does 0-60 in 3.4 seconds. Before you even watch the video above, you can imagine how it will end, as the retuned Atieva Edna rips 0-60 mph in 2.94 seconds. Atieva clocked the quarter mile at 11.3 seconds at 117 mph. It's worth noting that driver skill can have a lot to do with a car's straight-line performance. We've witnessed Viper's elapsing the quarter mile in well under 12 seconds, which means it should be quicker in this test than the i8, if not the Edna. Still, the performance showcased in the video is exceptional. To improve Edna's stats, Atieva says it has used testing data to fine tune its AC induction motors at higher speeds once it got low-speed performance locked in. After testing in the hot California sun, including the race you see above, Atieva drove Edna 90 miles home with range to spare. As for production plans, Atieva will put this powertrain into a sedan slated for sale in 2018. In the meantime, the company will keep testing and tuning its working prototype, and has even invited the public to put their cars up against Edna in future sessions.

Stellantis reports record margins, $7B profits despite chip shortage

MILAN — Automaker Stellantis on Tuesday said it achieved faster-than-expected progress on synergies and record margins in its first six months as a combined company, despite suffering 700,000 units in lower production due to interruptions in the semiconductor supply chain. The company — formed from French carmaker Peugeot PSAÂ’s takeover of the Italian-American company Fiat Chrysler — reported net profit of 5.9 billion euros ($7 billion) in the first half of 2021, compared with a loss 813 million euros during the same period a year earlier, which was impacted by the coronavirus restrictions around the globe. Shipments rose 44% to 3.2 million units, while revenues rose 46% to 75 billion euros. “We are very pleased with the speed with which the new team has begun to execute as one company, as Stellantis,Â’Â’ Chief Financial Officer Richard Palmer told reporters. Semiconductor shortages accounted for 200,000 units of production losses in the first quarter and 500,000 in the second quarter. Semiconductors are used more than ever before in new vehicles with electronic features such as Bluetooth connectivity and driver assist, navigation and hybrid electric systems. Stellantis achieved 1.3 billion euros in cost savings in the first half, mostly by sharing investments in new technologies and platforms, which Palmer said was a faster rate than initially forecast. It aims to achieve 80% of the targeted 5 billion in cost savings by 2024. “These synergies allow us to continue to invest in the electrification strategy, which we talk about every day,” Palmer said. Stellantis, which lags competitors in rolling out electric vehicles, plans to launch 21 fully electric or plug-in gas electric hybrid vehicles over the next two years. North American posted record profitability on global sales of Ram trucks and the strong launch of the Jeep Wrangler 4xe, which was the best-selling plug-in gas electric vehicle in the United States in the second quarter. Stellantis was the market leader in South America and second in Europe. The results were presented on a pro-forma basis, taking into account the performance of each of the carmakers as separate entities during 2020.
