Dodge Challenger spied exercising supercharged Hellcat Hemi V8

One of the prime complaints against the Dodge Challenger is that, even in SRT8 guise, its 470 horsepower is responsible for hauling over 4,200 pounds of vehicle. For comparison, the 420 hp in the Ford Mustang GT only has to deal with 3,618 lbs. Things only get worse from there, as the higher-performance variants of both the Mustang and the Chevrolet Camaro are far more powerful than an SRT8 without adding on much heft.
So what is Chrysler to do? The correct answer is add a whole lot more grunt to its hefty two-door and even the odds. That's where the all-new Hellcat engine comes into play. We reported on this engine in May, and suggested that the Hellcat, a supercharged powerplant based on a 6.4-liter V8, would easily generate 500 to 570 hp and could likely arrive boasting more than 600 ponies.
Chrysler's ace in its sleeve has now been spied testing, with a number of Hellcat-equipped Challengers running the potent new engine both in more urbanized areas and under the sun of Death Valley. The hoods on these testers have been raised to accommodate the engine, and that camouflage over the fascias of these prototypes is there to hide a larger air intake. We also note what appears to be a new split grille under wraps. As for power output, our spies are now suggesting a Viper-equalling 640 hp from the Hellcat-equipped cars.

Stellantis expects to hit emissions target without Tesla's help

Franco-Italian carmaker Stellantis expects to achieve its European carbon dioxide (CO2) emissions targets this year without environmental credits bought from Tesla, its CEO said in an interview published on Tuesday. Stellantis was formed through the merger of France's PSA and Italy's FCA, which spent about 2 billion euros ($2.40 billion) to buy European and U.S. CO2 credits from electric vehicle maker Tesla over the 2019-2021 period. "With the electrical technology that PSA brought to Stellantis, we will autonomously meet carbon dioxide emission regulations as early as this year," Stellantis boss Carlos Tavares said in the interview with French weekly Le Point. "Thus, we will not need to call on European CO2 credits and FCA will no longer have to pool with Tesla or anyone." California-based Tesla earns credits for exceeding emissions and fuel economy standards and sells them to other automakers that fall short. European regulations require all car manufacturers to reduce CO2 emissions for private vehicles to an average of 95 grams per kilometer this year. A Stellantis spokesman said the company is in discussions with Tesla about the financial implications of the decision to stop the pooling agreement. "As a result of the combination of Groupe PSA and FCA, Stellantis will be in a position to achieve CO2 targets in Europe for 2021 without open passenger car pooling arrangements with other automakers," he added. Tesla's sales of environmental credits to rival automakers helped it to announce slightly better than expected first-quarter revenue this week. The next tightening of European regulations will soon be the subject of proposals from the European Commission. The 2030 target could be lowered to less than 43 grams/km.

The Dodge Demon gets a Drag Mode and a lesson in Newtonian physics

It's Thursday morning, which means we have more news on the upcoming Dodge Demon, the pumped-up Challenger Hellcat variant that's looking to cause mayhem at a drag strip near you. This week's video, "Third Law," shows the Demon's revised suspension in action and displays another one of SRT's cryptic messages. Dodge claims that the 6.2-liter supercharged Hemi V8 in the Hellcat twins is compromised because it's fitted to a car that needs to be comfortable on the street in addition to a performer on the drag strip. Not so with the Demon, as Dodge says the car is "designed to be highly competent in all drive modes and configurations," including the all-new Drag Mode. Dodge says details about the new mode will trickle out over the next few weeks, but all the info this week focused on suspension. The "Third Law" in this week's title refers to Isaac Newton and motion: "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body." We're not sure what Newton would have thought seeing the sidewall wrinkling Nitto NT05R drag radials in action, but he'd probably have a reaction of some sort himself. An ideal suspension setup for the drag strip makes for a poor setup on the road. As Dodge puts it, the "old school" way to set up a drag car was to "get the quickest reacting springs upfront, the softest rebound front shocks that wouldn't restrict the springs' reaction, remove any restrictions (sway bar) and increase the compression of the rear shocks." This would give a car great front to rear weight transfer but made for very poor lateral direction control, meaning minor corrections were difficult. The Demon's Drag Mode will use electronics to give the car the best combination of launch and lateral stability. Dodge listed some of the parts to help aid in this goal. They also gave us a few equations that we can't make sense of. Let us know if you have any clues.
