Tesla leads and Infiniti bleeds in Consumer Reports' satisfaction survey

According to Consumer Reports, Tesla owners are more likely to rave about their vehicles than any other brand. And we're not surprised — Tesla has performed very well in past customer satisfaction surveys, despite the fact that the electric cars themselves tend to have more problems than most other automobiles. Second place went to Lincoln, which interestingly had a higher cumulative score than Tesla in individual category measurements like comfort and storage space. Ram, a truck-only brand, rounded out the top three. The consumer-focused magazine bases its owner satisfaction score on responses to a very simple question: Would you buy this exact car again? The higher percentage of owners who answer "definitely yes" to that question, the higher the satisfaction score. Further breakdowns are scored for other parts of the ownership experience, which is why brands that rank poorly in Consumer Reports' own reliability charts — like Tesla and Lincoln, for example — can still earn top marks for satisfaction. The lowest-ranked brands for satisfaction are Cadillac, Nissan and Infiniti. Interestingly, Cadillac performed better than average in Driving and Comfort and middle-of-the-road in the In-Car Electronics and Cabin Storage, but like most other brands, scored poorly in Value. In fact, only Subaru, Mazda and Volkswagen scored better than average in Value. Nissan and especially Infiniti earned comparatively low marks across the board to go along with the bottom-of-the-barrel satisfaction score. Here's the full list of automakers from Consumer Reports' satisfaction survey, ranked in order from best to worst: Tesla Lincoln Ram Chrysler Subaru Hyundai Porsche Dodge Mazda Toyota Kia Mini BMW Ford Audi Honda Volvo Volkswagen Lexus Jeep GMC Chevrolet Mercedes-Benz Buick Cadillac Nissan Infiniti It's worth diving into the individual category scores in addition to the official finishing order for a full look at the results. For instance, despite the fact that automakers like Lincoln and Ford use similar infotainment systems, their In-Car Electronics scores don't quite match up. Also, some automakers have full lineups with multiple cars, trucks and SUVs while others offer just a couple of nameplates. Head on over to Consumer Reports for all the details.

Jay Leno welcomes a 2016 Cadillac CTS-V into the garage

After checking out a multitude of classic cars and customs over the past few weeks, Jay Leno switches things up with a modern performance machine in the latest video from the garage – a 2016 Cadillac CTS-V. Leno is curious about Caddy's attempt to challenge the BMW M5 and Mercedes-Benz E63 AMG S, and he takes a long, technical look at the sedan with chief engineer David Leone. Not content to just peek under the hood, Leno puts the CTS-V up on the rack to see what it packs underneath the svelte body. Once he gets the lowdown on the Caddy's engineering, it's time for a drive. Leno also flexes his interviewing skills while behind the wheel and gets even more info about the CTS-V's capabilities from Leone. He seems fairly impressed, but Leno's most entertaining question about the 640-horsepower sedan is whether it can do a burnout. He provides a definitive answer to that at the end of the clip.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
