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.

Is it time for American carmakers to give up on dual-clutch transmissions? [w/poll]

Last week, in the midst of Detroit's first days seeking relief in Chapter 9 of the bankruptcy code, Automotive News contributor Larry P. Vellequette penned an editorial suggesting that American car companies raise the white flag on dual clutch transmissions and give up on trying to persuade Americans to buy cars fitted with them. Why? Because, Vellequette says, like CVT transmissions, they "just don't sound right or feel right to American drivers." (Note: In the article, it's not clear if Vellequette is arguing against wet-clutch and dry-clutch DCTs or just dry-clutch DCTs, which is what Ford and Chrysler use.) The article goes on to state that Ford and Chrysler have experimented with DCTs and that both consumers and the automotive press haven't exactly given them glowing reviews, despite their quicker shifts and increased fuel efficiency potential compared to torque-converter automatic transmissions.
Autoblog staffers who weighed in on the relevance of DCTs in American cars generally disagreed with the blanket nature of Vellequette's statement that they don't sound or feel right, but admit that their lack of refinement compared to traditional automatics can be an issue for consumers. That's particularly true in workaday cars like the Ford Focus and Dodge Dart, both of which have come in for criticism in reviews and owner surveys. From where we sit, the higher-performance orientation of such transmissions doesn't always meld as well with the marching orders of everyday commuters (particularly if drivers haven't been educated as to the transmission's benefits and tradeoffs), and in models not fitted with paddle shifters, it's particularly hard for drivers to use a DCT to its best advantage.
Finally, we also note that DCT tuning is very much an evolving science. For instance, Autoblog editors who objected to dual-clutch tuning in the Dart have more recently found the technology agreeable in the Fiat 500L. Practice makes perfect - or at least more acceptable.

US prepares to sue Fiat Chrysler over diesel emissions testing

NEW YORK - The Justice Department plans to file a civil lawsuit against Fiat Chrysler Automobiles NV over excess diesel emissions as early as this week if no agreement is reached with the Italian-American automaker, two sources briefed on the matter said on Wednesday. The Environmental Protection Agency in January accused FCA of illegally using undisclosed software to allow excess diesel emissions in about 104,000 cars and SUVs, the result of a probe that stemmed from regulators' investigation of rival Volkswagen AG. The EPA and California Air Resources Board have been in talks with FCA about the excess emissions and whether the agencies would approve the sale of 2017 FCA diesel models. A federal judge in California has set a May 24 hearing on a series of lawsuits filed by owners of vehicles against Fiat Chrysler and the Justice Department is expected to file its action by then if no agreement is reached. FCA said on Wednesday it believed that any litigation would be "counterproductive" to ongoing discussions with the EPA and California Air Resources Board. The company added that "in the case of any litigation, FCA US will defend itself vigorously, particularly against any claims that the company deliberately installed defeat devices to cheat U.S. emissions tests." The Justice Department took the same procedural step in early 2016 against Volkswagen, nearly four months after the German company admitted using software to emit excess diesel emissions in nearly 500,000 vehicles. The Justice Department has had an ongoing criminal investigation into FCA's conduct since last year, Reuters reported in January. The probe has turned up internal emails written in Italian and other documents about engine development and emissions issues, sources briefed on the probe said. U.S. regulators said FCA failed to disclose engine management software in 104,000 U.S. 2014-2016 Jeep Grand Cherokees and Dodge Ram 1500 trucks with 3.0-liter diesel engines. The European Commission has launched legal action against Italy for failing to respond to allegations of emission-test cheating by Fiat Chrysler in a procedure that could lead to the country being taken to court. The EPA has said the maximum possible fine against FCA could be $4.6 billion. In February, FCA said it had received requests for information and subpoenas from U.S. federal and state authorities, including the Securities and Exchange Commission, for diesel issues.
