Chrysler readying Hellcat V8 with Viper-like power

A monstrous supercharged V8 engine could be in store for Chrysler and SRT products, if recent rumors are to be believed. Allpar is reporting that the forced-induction V8 - Chrysler's first, if this goes down - could make its debut this summer.
The story goes that the Hellcat would be based on a 6.2-liter Hemi engine, rather than on the existing 5.7- or 6.4-liter versions of the company's vaunted mill. In any case, the general consensus is that the motor will have gobs of power. Modest estimates call for between 500 to 570 horsepower, with some outliers predicting a figure as high as 600 hp. That figure would put the output would place the Hellcat awfully close to that of the 640-hp V10 in the SRT Viper, too. Allpar contends that a slightly lower powered version would allow Chrysler to keep costs below that of the more powerful Ford Shelby GT500, which might be a sweet spot.
The Hellcat could debut in a number of SRT products. SRT versions of the Charger, Challenger and 300 are all up for grabs, as is the rumored SRT Barracuda.

Dodge Scat Packages add Mopar performance upgrades in three stages

Dodge has revealed what it calls Scat Package Stage Kits that enhance the performance of the Charger and the Challenger equipped with the 5.7-liter V8, and the Dart equipped with the turbocharged 2.4-liter inline four-cylinder engine. The Scat Packs use Mopar performance parts that also can be bought separately. Most of the upgrades increase engine output, but Dodge somehow manages to not specifically mention the power gains associated with each Scat Pack.
The three Scat Packs offered for the V8-powered cars focus on higher power ratings, and each stage comes complete with a unique engine-management calibration to optimize output. Stage one comes with a cold-air intake and a cat-back exhaust; stage two adds a performance camshaft; and stage three really gives you the goods, adding ported polished cylinder heads and performance headers.
For the Dart, the Scat Packs focus on engine, transmission, chassis and brake upgrades. Stage one will net you a cold-air intake, a short-throw shifter and slotted rotors with performance brake pads; stage two adds a cat-back exhaust system and an engine-management calibration to increase output by taking advantage of premium-octane gasoline; and stage three adds 13-inch vented brake discs up front clamped by four-piston calipers, suspension with adjustable springs and struts and performance front and rear antiroll bars.

Killing the Dart and 200 might lower FCA's fuel economy burden

Killing the Dodge Dart and Chrysler 200 could allow FCA US to take advantage of an intriguing quirk in the next decade's fuel economy regulations. By increasing its ratio of trucks versus cars, the automaker might not need to worry so much about hitting the more stringent efficiency rules. At first thought, it might seem harder for an automaker with a ton of trucks to meet the government's mandated 54.5 mile per gallon corporate average fuel economy for 2025. However, every company doesn't need to hit that lofty figure, according to The Detroit Free Press. The exact target varies by the product mix between trucks and cars. "While passenger car and light truck categories have separate CAFE targets, it's still true that more trucks versus cars in a company lineup means a lower combined CAFE target," Brandon Schoettle, Project Manager Sustainable Worldwide Transportation at the University of Michigan Transportation Research Institute, told Autoblog. "While passenger car and light truck categories have separate CAFE targets, it's still true that more trucks versus cars in a company lineup means a lower combined CAFE target." FCA US' current product blend has 80 percent pickups and CUVs, which means the company stands to benefit from a lower fuel economy target. It might not seem entirely fair environmentally, but this is a great move from a business perspective. The new CAFE rules aren't set in stone, according to The Detroit Free Press, but potentially taking advantage of the regulation is just one more reason to cut the Dart and 200. Modern crossovers also aren't gas guzzlers like older SUVs, which could make it easier to hit the fuel economy target. "Utilities offer practicality and versatility that cars do not, and now, built on car architectures, they do not penalize consumers on fuel economy as they once did," AutoTrader Senior Analyst Michelle Krebs told Autoblog. Schoettle warns that FCA is still making a gamble by killing the small sedans. "Depending on the previous sales volumes and how much these vehicles might have exceeded their specific CAFE targets, it's possible that these cars helped earn CAFE credits for FCA that they could bank for future use," he said.
