2017 North American Car, Truck, and Utility Vehicle of the Year finalists revealed

The finalists for the 2017 North American Car, Truck, and Utility Vehicle of the Year were announced Tuesday at AutoMobility LA ahead of the 2016 LA Auto Show. Approximately 60 judges, including Autoblog's editor-in-chief Mike Austin, evaluated over 40 vehicles and named three models as the finalists in each category. The award for the Utility Vehicle of the Year is new for 2017 and separates SUVs, crossovers, and minivans from pickup trucks. The finalists are: Car of the Year: Chevrolet Bolt Genesis G90 Volvo S90 Truck of the Year: Ford F-Series Super Duty Honda Ridgeline Nissan Titan Utility Vehicle of the Year Chrysler Pacifica Jaguar F-Pace Mazda CX-9 The winners for the 24th annual NACTOY awards will be named on January 9 at the Detroit Auto Show.

Lexus tops Consumer Reports reliability rankings, unseating Mazda

Lexus is back on top of Consumer Reports' annual reliability rankings. Toyota Motor Corp's luxury division dethrones last year's winner, upstart Mazda, to second place, while the Toyota brand itself rounds out the podium in third place. In general, while Asian brands topped the list, Europeans ranked second, and domestics brought up the rear.  Lexus' high marks stem from the Land Cruiser Prado-based GX SUV, which got a perfect score of 100. Mazda's second place finish was the result of strong showings by the Miata, CX-9, CX-5, and CX-30, but dragged down by the Mazda 3's mid-pack score. Likewise, nearly all of Toyota's lineup, from Prius to Avalon, all had very high marks, but the RAV4 and Corolla Hatchback brought down the class average. Like last year, the only American brand to break into the top ten was Buick, which ranked 5th thanks to good scores for the Envision and Encore (though the Enclave ranked sub-par). Eight of the top 10 brands were Japanese, with Infiniti in 4th, and Honda, Subaru, Acura and Nissan following Buick in that order. Mini, in 10th place, was the only European brand in the top 10. The bottom spots went to Jeep, Tesla, and once again Lincoln in dead last. While all Lincolns received poor scores, the Aviator was notable for getting only 3 points out of 100. Similarly, last year's lowest-scoring vehicle was the Ford Explorer, with which the Aviator shares a platform. It wasn't all gloom from the domestics, however. The Chevrolet Trailblazer tied the Lexus GX with a perfect score, but overall Chevy brand ranked 14th, pulled down by the Corvette, Silverado 1500 and Tahoe. The Tahoe tied with the GMC Yukon with the lowest scores this year, just 2 points each. Both the Silverado 2500HD and the nearly identical GMC Sierra 2500HD were among to top scoring American vehicles, along with the Ford Bronco Sport, Mustang Mach E, Ranger and Chrysler 300. Consumer Reports also points out that the oft-said line that electric vehicles are less prone to problems due to fewer moving parts isn't necessarily true. The Audi E-Tron and Tesla Model X each got a score of 5, the lowest of their respective brands, due to more and more technology being crammed into these higher-priced EVs.

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.
