Mazda files patent applications for inline-six technology, new transmission

We've known for some time that Mazda is one of the OEMs getting back on the inline-six engine bandwagon, and a report from Japan gives us a glimpse of some of the automaker's plans. Mazda has filed patent applications for both new exhaust components (depicted with an inline-six) and a new eight-speed automatic transmission.  The news comes from a blog called T's Media (fire up Google Translate), which located the new hardware in two separate fillings, one for exhaust system components and one for the new transmission.  Mazda's lineup has been exclusively powered by four-cylinder engines since the demise of the last-generation CX-9, which utilized a 3.7-liter V6 sourced from Ford. Since, Mazda has relied on turbocharging to get more power out of its SkyActiv four-pots, but changes may be coming. Prior reports have indicated that Mazda wants a new, larger engine architecture to power vehicles built on a new, larger platform. This new chassis is expected to accommodate longitudinal, rear-wheel drive powertrains, which could spawn larger crossovers and SUVs. It could also potentially underpin a new rear-wheel drive coupe, if Mazda decides to go that route.  While the inline engine itself is not news, what we're seeing here might actually be hints as to Mazda's approach to the next generation of its SkyActiv engine architecture. Mazda's exhaust patent seems to describe a scalable — perhaps even modular — setup intended to be used with inline and potentially even V-engines.  "Provided is an engine exhaust structure capable of securing exhaust efficiency while reducing the size of the engine by changing the structure of an exhaust port," a translation of the patent application's introduction says. "[T]here has been proposed a technique for collecting exhaust gas discharged from each cylinder inside a cylinder head without using a separate exhaust manifold with the aim of downsizing the engine." In other words, Mazda is looking for ways to make its future engines more compact, and the strategy detailed here is the use of an integrated exhaust manifold, similar to what other automakers (such as Honda and Ford) have utilized on their smaller-displacement turbocharged engines. The sketch above of an inline-six engine with just two exhaust ports illustrates this concept.  The eight-speed transmission, while noteworthy in its own right as Mazda currently relies on aging six-speeds, doesn't seem to offer us anything particularly game-changing.  Related Video:

2020 Hyundai Palisade vs. Ascent, Pilot, Highlander and CX-9: How they compare on paper

We've finally had our first drive of the 2020 Hyundai Palisade and found it to be well-equipped for sales success. It nails the formula that some of the most successful three-row crossovers have, the aforementioned seating capacity, high driving position, all-wheel-drive availability and a V6 engine. Of course, it also offers a unique and menacing-looking exterior that ought to stand out in the parking lot. To dig deeper into how it compares to other three-row family crossovers, we've fired up the old Autoblog Comparo Generator 3000 (™) and lined the all-new 2020 Palisade up against the 2019 Subaru Ascent, 2019 Honda Pilot, 2019 Toyota Highlander and 2019 Mazda CX-9. Besides being two of last year's best-selling three-row SUVs, the Pilot and Highlander are also the closest in general concept to the new Palisade, while the Ascent and CX-9 also offer a comparable turbocharged four-cylinder powertrain. The CX-9 is also one of our favorites in the segment, and the Ascent is one of the newest entrants on the scene. There are of course numerous other worthy contenders, including the Chevrolet Traverse, GMC Acadia, Volkswagen Atlas, Nissan Pathfinder, Hyundai Santa Fe and the best-selling Ford Explorer, so if you want to see their specs, check out the Autoblog compare tool. Performance and fuel economy The Subaru, as is so often the case, is the oddball. It has a 2.4-liter turbocharged horizontally opposed four-cylinder (aka a flat-four or a boxer-four) that produces a comparatively modest horsepower rating, but a greater amount of torque. That's typical for turbocharged engines such as Mazda CX-9's turbo inline-four that produces 250 horsepower on premium fuel (227 hp on 87 octane) and 310 lb-ft of torque (the VW Atlas also offers a base turbo-four). The Hyundai, Honda and Toyota, meanwhile, go about it the old-fashioned way, with naturally aspirated V6 engines displacing 3.8 liters in the Hyundai, and 3.5 liters with the two Japanese crossovers. The Toyota and Hyundai lead the pack in horsepower, with the Toyota taking top honors by just 4 horses. The Honda weighs less, though, so their acceleration should be comparable. The Subaru actually accelerates on par with its V6-powered competitors, probably due in part to its continuously variable transmission. The fuel economy trophy goes to the Ascent.

Mazda MX-5 GT gets green light

The Mazda MX-5 Miata is as popular around the Autoblog offices as Kate Upton posters are around fraternity houses. Few staffers have much criticism for Mazda's ubiquitous roadster, and fewer still aren't overjoyed when one arrives in their driveway. So you can imagine how a report from Auto Express about a more potent MX-5 model is going over in our offices today.
The new model, which was shown in concept form as the Mazda MX-5 GT at the Goodwood Festival of Speed, has a slight catch, though. First, we have absolutely no idea if Mazda will bring the MX-5 GT to the US. Secondly, and perhaps more problematically, this isn't a production car - it's a kit from the team at Jota Sport.
Now, to be fair, the kit doesn't sound like a bad thing. It bumps the UK-spec 2.0-liter, 157-horsepower engine up to 203 hp thanks to a sports exhaust and a revamped ECU (46 horsepower from an ECU and exhaust in a naturally aspirated car?). To make the little Miata even more agile, Jota has also fiddled with the suspension. AE doesn't mention things like the grippy tires or Recaro seats that were found on the concept, though.
