2015 Dodge Challenger SRT Hellcat has 707 glorious horsepower [w/video]

Hold onto your butts. "600-plus horsepower" is what we were told to expect from the 2015 Dodge Challenger SRT with its 6.2-liter supercharged Hellcat V8 engine. But as we've just learned, those were incredibly conservative numbers. Dodge has officially announced that the range-topping Challenger will hit the asphalt with 707 - seven hundred and seven - horsepower, making it the "most powerful muscle car ever."
Of course, 707 hp is only part of the story, as the Hellcat has also been confirmed to produce 650 pound-feet of torque. All that power will run exclusively to the rear wheels through an eight-speed automatic transmission that differs from other Challengers. The new gearbox, 8HP90 (rather than the 8HP70) is "upgraded to handle the extra power and torque," says Dan Reid, SRT's manager of product design and motorsports.
We certainly hope you're prepared to spend a ton of money replacing tires.

Stellantis wants to outfit cars with AI software to drive revenue

MILAN — Carmaker Stellantis announced a strategy Tuesday to embed AI-enabled software in 34 million vehicles across its 14 brands, hoping the tech upgrade will help it bring in 20 billion euros ($22.6 billion) in annual revenue by 2030. CEO Carlos Tavares heralded the move as part of a strategy that would transform the car company into a “sustainable mobility tech company,” with business growth coming from features and services tied to the internet. That includes using voice commands to activate navigation, make payments and order products online. The company is expanding existing partnerships with BMW on partially automated driving, iPhone manufacturer Foxconn on customized cockpits and Waymo to push their autonomous driving work into light commercial vehicle delivery fleets. StellantisÂ’ embrace of artificial intelligence and expansion of software-enabled vehicles is part of a broad transformation in the auto industry, with a race toward more fully electric and hybrid propulsion systems, more autonomous driving features and increased connectivity in automobiles. Ford and General Motors also are banking on dramatically increased revenue from similar online subscription services. But the automakers face immense competition for monthly consumer spending from movie and music streaming services, news outlets, Amazon Prime and others. Stellantis, which was formed from the combination of PSA Peugeot and FCA Fiat Chrysler, said the software would seamlessly integrate into customers' lives, with the capability of live updates providing upgraded services over time. New products will include the possibility to subscribe to automated driving features, purchase usage-based car insurance or even increase the power of the vehicle with a tune-up to add horsepower. As a baseline, Stellantis generates 400 million euros in revenue on software-generated services installed in 12 million vehicles. To meet the targets, Stellantis will expand its software engineering team of 1,000 to 4,500 in North America, Asia and Europe. More than 1,000 of the expanded team will be retrained in house. Stellantis also announced a new partnership with Foxconn to develop semiconductors to cover 80% of the companyÂ’s needs and simplify the supply chain. The first microchips from the partnership are targeted to be installed in vehicles in 2024.

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.
