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.

2017 Chrysler Pacifica Hybrid scored 84 MPGe in government testing

The 2017 Chrysler Pacific, in non-hybrid form, was already at the top of the minivan heap in terms of EPA-rated fuel economy. Now the government agency has released its official test numbers for the Pacifica Hybrid, and they're looking pretty good. The non-hybrid Pacifica achieved 28 highway, 18 city, and 22 combined miles per gallon, which compared favorably to the 2016 Honda Odyssey's 28/19/22 and Nissan Quest's 27/20/23 ratings. You can read more about the regular Pacifica's scores right here. But none of these vans compare to the Pacifica Hybrid, which is incidentally the only hybrid in the class. FCA claims that the EPA's numbers are even better than the anticipated 80 MPGe, although we can't speak to whether that's an honest admission or a too-convenient claim. But there's no denying that the official rating – 84 MPGe – is impressive. If you aren't familiar with the MPGe rating, no worries. It's not as straightforward as conventional EPA MPG ratings, but a layperson can understand how it works. MPGe stands for miles per gallon equivalent, and measures fuel economy based on the energy content of a gallon of petroleum-based gasoline. For those who like formulas, the Automotive X Prize once defined MPGe as (miles driven) / [(total energy of all fuels consumed)/(energy of one gallon of gasoline)]). As for a conventional rating, the EPA only provides a combined city/highway number on the Monroney sticker, and an FCA spokesperson told us that the rating for the Pacifica Hybrid will be 32 MPG. This represents the hybrid working as normal, not in EV-only mode. It's also an improvement of almost 10 MPG over the combined ratings of the top three conventional minivans in the segment, including the non-hybrid Pacifica. Range is also fantastic. The EPA rated the total EV-only range as 33 miles, and the overall combined range at a staggering 566 miles. And that's from a fuel tank that's just 17 gallons (compared to the 19-gallon tank in the conventional Pacifica, which nets it a 418-mile EPA-rated range). FCA is going to extraordinary lengths to credit its eFlite transmission-generator unit, which can supply electric power to the front wheels if necessary. It's a piece of equipment that represents a substantial engineering investment, and apparently that's all paid off. Chrysler tells us that the Pacifica Hybrid will go on sale next month, and that dealers will get more volume in Q1. Related Video: This content is hosted by a third party.

FCA and Cummins named in diesel emissions class-action lawsuit

Chrysler is now the first United States-based carmaker to be sued for allegedly skewing emissions results. In a move that sounds eerily similar to the troubles of European manufacturers, Chrysler is claimed to have hid diesel engine characteristics causing emissions as much as 14 times higher than permitted by regulations. According to Bloomberg, the lawsuit alleges that Chrysler, together with its diesel engine partner Cummins, has concealed the nitrogen oxide output of certain Ram vehicles produced between 2007 and 2012. The NOx pollutants were meant to be broken down in a process called regeneration in the truck's NAC system, or NOx Absorption Catalyst, which predated the 2013-introduced SCR, or Selective Catalytic Reduction system. By design, the NAC captures and stores NOx emissions, converting them to nitrogen and oxygen through a catalytic process. The lawsuit claims the Cummins engine's system has a limited capacity to store the emissions, and as a result the pollutants escape, increasing emissions, worsening fuel consumption and wearing down the catalytic converter. The later, cleaner SCR system uses a urea-water injection, and it gradually replaced the NAC on Cummins 6.7-liter engines, as it was first implemented in 2011 and made standard in 2013. As Bloomberg notes, the model years of Ram trucks involved in the lawsuit predate the earliest Volkswagen "Dieselgate" models by two years. The lawsuit, filed on behalf of 500,000 truck owners, accuses Chrysler and Cummins of fraud, false advertising and racketeering. As an underlying motive, the filing mentions a 2001 change in EPA emissions standards. Announced to become effective in 2010, the EPA requirements drove Chrysler and Cummins to try and reach those already by 2007. However, the NAC system is said to have fallen short of these goals, and the filing claims that Chrysler and Cummins chose to "rig" the engines instead. The affected vehicles predate the 2014 merger of Chrysler and Fiat. FCA US has released a statement regarding the lawsuit, saying it will contest the lawsuit "vigorously".
