2013 North American Car and Truck/Utility of the Year finalists announced [w/poll]

2012 is almost in the books and automakers are spending December gearing up for the 2013 auto show season, which tips off next month at the Detroit Auto Show. Traditionally, the latter opens up with the announcement of the North American Car and Truck/Utility of the Year awards, and this year figures to be no different.
But up until this moment, we didn't know which six vehicles would be parked ahead of the stage as finalists, with executives and engineers waiting for the winners to be disclosed. Whittled down from October's "short list" of nominees (11 cars and 10 truck/utility vehicles), the finalists are as follows:

Mazda files patents for a sequential twin-turbo setup

Mazda has a history of interesting engine technologies, from yesterday's rotary engine to tomorrow's compression ignition engine, and new patents show it still may have some internal combustion tricks up its sleeve. The one on display in these patents isn't especially new in concept, though. A sequential twin-turbocharger setup is something Mazda itself used on the third-generation RX-7. But it's something we haven't seen much of lately. It looks like it could have some possible advantages over older sequential systems, and it has some potential advantages for enthusiasts. First a quick and dirty primer for what makes a sequential twin-turbo system distinct from other twin-turbo systems. In many twin-turbo engines, there are simply two turbos that work together as one bigger turbo. They're the same size, and they spool up at the same time. With a sequential setup, at low rpm, a smaller turbocharger is spooled up first at low-rpm for quicker throttle response, and as the rpm and exhaust pressure increases, a valve opens up that allows a larger turbocharger to also spool up and provide high-rpm boost. That's basically how the Mazda design shown above functions. A big flap blocks off the larger turbocharger exhaust inlet, channeling all the exhaust to the smaller turbo. When more exhaust is available at high rpm, it looks like that flap opens up to spool up the big turbo, too. What's interesting here is that the way the turbochargers are packaged takes up less space than past systems. It looks like both turbos are contained in one unit that shares the same exhaust outlet, meaning the exhaust manifold could be kept simple and compact. In fact, the piping for compressed intake air could also be shared, reducing the amount of piping, which would further decrease the amount of materials and possible failure points. There are a number advantages of making this system smaller. The potential applications of the system are much greater, since it could fit in smaller cars with smaller engine bays. Making the system smaller also means that there won't be as much weight, which is important from both fuel economy and performance standpoints. Finally, the smaller setup likely uses fewer materials, which could make the system cheaper and thus easier to offer on a wider range of vehicles, or at least more profitable for Mazda.

Toyota, Mazda form electric car technology venture

TOKYO — Toyota has established a new venture to develop electric vehicle technology with partner Mazda, seeking to catch up with rivals in an increasingly frenetic race to produce more battery-powered cars. Policymakers in key markets like China are pushing a shift to electric cars over the next two to three decades, while relatively new rival Tesla is gaining momentum and diesel cars are going through the fallout of the Volkswagen diesel scandal, pressuring traditional automakers to crank up plans for fully electric vehicles (EVs). At the same time, declining battery costs are enabling more power to be packed into cars, making an electric car future easier to imagine. Toyota said in a statement the new company will develop technology for a range of electric cars, including mini vehicles, passenger cars, SUVs and light trucks. Toyota will take a 90 percent stake in the joint venture, called EV Common Architecture Spirit Co Ltd, while Mazda and Denso Corp, Toyota's biggest supplier, will each take 5 percent. The plans build on a partnership announced in August when Japan's biggest automaker agreed to take a 5 percent stake in Mazda and two said they would jointly develop affordable electric vehicle technologies. Although Toyota is providing most of the financial firepower and existing EV know-how, Mazda's engineers have gained the admiration of the industry with breakthrough technologies such as its compression ignition engine announced last month. Shares in Mazda surged to end the day 3 percent higher, while those in Denso rose 1.8 percent. Toyota shares were flat. Both automakers are somewhat behind rivals, with neither having a fully electric passenger car on the market yet. After years of focusing on bringing hydrogen fuel cell vehicles to the market, Toyota last year set up a division to develop electric cars which is led by President Akio Toyoda, and said it plans to introduce EVs in China in the coming years. Toyota has also announced it will bring a game-changing solid-state EV battery to market by 2022. That division would continue as a separate entity from the new joint venture, a Toyota spokeswoman said, while adding that the two teams would co-operate on technology development. Mazda has an R&D budget a fraction of Toyota's, which has made it difficult to develop electric cars on its own. Even so, it has said it plans to launch EVs in 2020.
