8 things you learn while driving a cop car [w/videos]

Let me start off with the obvious: it is absolutely illegal to impersonate a police officer. And now that that's out of the way, I'd just like to say that driving a cop car is really, really cool. Here's the background to this story: Dodge unveiled its redesigned 2015 Charger Pursuit police cruiser, and kindly allowed Autoblog to test it. That meant fellow senior editor Seyth Miersma and I would spend a week with the cop car, and the goal here was to see just how different the behind-the-wheel experience is, from a civilian's point of view. After all, it's not technically a police car – it isn't affiliated with any city, it doesn't say "police" anywhere on it, and it's been fitted with buzzkill-worthy "NOT IN SERVICE" magnets (easily removed for photos, of course). But that meant nothing. As Seyth and I found out after our week of testing, most people can't tell the difference, and the Charger Pursuit commands all the same reactions as any normal cop car would on the road. Here are a few things we noticed during our time as wannabe cops. 1. You Drive In A Bubble On The Highway Forget for a moment that our cruiser was liveried with Dodge markings instead of those of the highway patrol. Ignore the large "NOT IN SERVICE" signs adhered around the car. Something in the lizard brain of just about every licensed driver tells them to hold back when they see any hint of a cop car, or just the silhouette of a light bar on a marked sedan. Hence, when driving on the highway, and especially when one already has some distance from cars forward and aft, a sort of bubble of fear starts to open up around you. Cars just ahead seem very reluctant to pass one another or change lanes much, while those behind wait to move up on you until there's a full herd movement to do so. The effect isn't perfect – which is probably ascribable to the aforementioned giveaways that I'm not really a cop – but it did occur on several occasions during commutes from the office. 2. You Drive In A Pack In The City My commute home from the Autoblog office normally takes anywhere from 25 to 30 minutes, and it's a straight shot down Woodward Avenue from Detroit's north suburbs into the city, where I live. Traffic usually moves at a steady pace, the Michigan-spec "five-over" speed.

Weekly Recap: Toyota propels hydrogen fuel cells

Toyota is serious about hydrogen fuel cells, and it wants the auto industry to follow suit. The Japanese automaker said this week it's releasing 5,680 fuel cell patents from around the world, including technologies used on its upcoming sedan, the 2016 Mirai. The move is unusual, but not unprecedented, as Tesla similarly released its electric vehicle patents last year. The idea for Tesla, and now for Toyota, is to spur development of alternative propulsion. "By eliminating traditional corporate boundaries, we can speed the development of new technologies and move into the future of mobility more quickly, effectively and economically," said Bob Carter, Toyota Motor Sales senior vice president of automotive operations, in a statement. Toyota's fuel cell patents will be free to use through 2020, though patents related to producing and selling hydrogen will remain open forever. Toyota said it would like companies that use its patents to share their own hydrogen patents, but won't require it. "What Toyota's doing is really a logical move, and really a good move for the industry," Devin Lindsay, principal powertrain analyst with IHS Automotive, told Autoblog. The announcement was made at the Consumer Electronics Show in Las Vegas. It comes as Toyota prepares to launch the hydrogen-powered Mirai in a limited number late this year in California. The launch will be extended to the Northeastern United States next year. Toyota also has announced plans to support networks of fueling stations in each region to try to smooth consumer adoption. The Mirai has a 300-mile range on a tank of hydrogen, and it takes about five minutes to refill. Fuel cells have been receiving increased attention recently, and Audi and Volkswagen debuted hydrogen-powered cars at the 2014 Los Angeles Auto Show. Honda, another proponent of the technology, also showed its updated FCV concept in November in Japan. The company, however, has delayed its fuel cell sedan a year until 2016. Like Toyota, Honda says its hydrogen-powered car will have a range of 300 miles or more. Meanwhile, Hyundai currently offers leases for fuel-cell powered Tucsons, which have a 265-mile range, in Southern California. Despite the optimism some automakers have for fuel cells, the technology still faces barriers. A lack of filling stations has long held it back, and many consumers are not familiar with the potential benefits.

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".
