Range Rover Sport SVR, Mazda CX-3, this week's news | Autoblog Video Podcast #533

On this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Reese Counts. We'll talk about the latest news and discuss a couple of the cars we've had in the office, the Land Rover Range Rover Sport SVR and the Mazda CX-3. We also have a look behind the scenes of a video we shot in Iceland. And of course, we'll help choose a new vehicle for a listener in our "Spend My Money" segment.

Mazda Skyactiv-X Review | The revolution begins with a squeeze-bang

The matte black Skyactiv-X prototype looks like a rough Mazda3, perhaps reconstructed after a bad wreck by an over-enthusiastic owner of a spot welder and lots of gaffers' tape. Ribbed ducts poke out of the dash sending two breaths of conditioned air to no one in particular. Even its revolutionary engine, the thing we're here to experience, is entombed in a massive, nondescript cover to mask its unseemly noises. It's a wild, strange way to meet a very unconventional vehicle that promises diesel-like fuel economy, a wide torque band, and an exotic method for burning less gas than ever before. It takes a few hours for Mazda's engineers to explain the fundamental principles of operation. For more detail, read our Skyactiv-X Spark Controlled Compression Ignition explainer, but here's a very brief overview. Skyactiv-X marries some traditional gasoline engine characteristics with a novel form of compression ignition called SPCCI. The key for Skyactiv-X is to use very high compression in the cylinder and an extremely lean fuel-air mixture. Squeezed right to the cusp of getting hot enough to blow up all on its own (which is very hard to predict), a squirt of extra gas and a spark interject to cross that compression-ignition threshold in a controlled and predictable manner. See the animation below: That takes a few essential components to get just right. One is a massive amount of computer processing power and some pressure sensors in the individual cylinders, because the ambient conditions change how and when these things happen. Skyactiv-X uses a clutched supercharger to pump in additional air when needed to nail the mixture precisely, and high-pressure injectors to get the low ratios of fuel to disperse properly in the chamber. And since it operates like a conventional gasoline engine sometimes, it uses valve timing to lower the very high compression ratio so it doesn't reach combustion ignition in that mode. In practice, the Skyactiv-X runs in compression ignition mode most of the time. In practical terms, that means it drives like a torquey gasoline Skyactiv engine. The torque curve is broad and flat — diesel-like in that respect. That also means it can get away with using a six-speed transmission and a lower final drive for better response. There's enough grunt and economy together that Mazda can let the engine spin faster — at 60 mph, it's running at roughly 1,000 more RPM than a similar gas engine, with greater efficiency.

Mazda ranks first for reliability in Consumer Reports, dethroning Toyota, Lexus

For time immemorial, or at least the past six years, Toyota and Lexus have sat at the top of Consumer Reports' annual survey of vehicle reliability. It was almost as much a given as blue skies and taxes. Not any more. Mazda has dethroned them both, ascending to the No. 1 spot for the first time. Mazda nabbed the top spot with powertrains and that used durable (and more fun) six-speed automatic transmissions instead of CVTs, which tend to be more fragile. Mazda also didn't rely on overly fancy infotainment systems, instead bucking industry trends with cockpits that discourage screen use during driving and encourage buttons and dials that can be handled without taking your eyes off the road. The most reliable Mazda was the MX-5 with a score of 98 out of 100, followed by the CX-30, CX-3, and CX-5, all scoring 85 or better. Overall, Toyota and Lexus still rank far above the average, taking the second and third spots respectively. Lexus was dragged down by problems pertaining to the LS, but CR didn't specify the nature of those issues. Buick was the most improved brand, jumping up 14 spots to claim fourth. Its show was attributed largely to the Encore, which received a score of 91. Honda moved up seven positions to round out the top five, but was denied a better position due to the Passport and Odyssey's scores in the mid-30s. Among European brands, Porsche ranked highest, at No. 9. BMW moved up five spots to 12th, while Audi kept its mid-pack position at 14th, and Mercedes brought up the rear among the German big three in 20th place. At the bottom of the list were Ford, Mini, Volkswagen, Tesla, and Lincoln falling 11 places to dead last. In particular, the Ford Explorer was called out for having the fewest points of any model, barely registering at all a score of 1, thanks to gremlins with engines, body, power equipment, electronics, and transmissions. Tesla's newly introduced Model Y crossover dragged down the electric carmaker's standing to the penultimate spot. Owners of the Model Y, which began production in January, have reported misaligned body panels that had to be fixed and mismatched paint including, in one case, human hair stuck in the paint, according to Consumer Reports. The Model Y finished with a "much worse than average" reliability rating. The rankings are taken annually based on a survey of 300,000 vehicles. Information from AP was used in this report.
