50 engineers kept the rotary alive at Mazda for 8 years

The Mazda RX-Vision concept is one of the standouts at this year's Tokyo Motor Show thanks to a drop-dead gorgeous design and a revival of the Wankel engine. The fact that the rotary is still in development at Mazda is thanks to a dedicated group of 50 engineers. According to Automotive News, their dream for the last eight years has been to bring this storied engine design back to the street. It won't be easy. Because of its design, the rotary suffers from poor fuel economy and high emissions. Making the challenge even harder, Mazda reportedly only gives them a small budget, but they continue to chip away at the problem. "These 50 engineers want to develop the rotary engine, therefore they joined Mazda," company research and development boss Kiyoshi Fujiwara told AN. "If I stop the rotary engine, probably they want to leave." For the Skyactiv-R under the RX-Vision's svelte hood, the team reportedly started from the 16X rotary project. Dating back to 2007, that 1.6-liter engine was supposed to improve torque and fuel economy thanks in part to direct injection. After additional development, insiders even suggested that the engineers might have finally solved the powerplant's issues. However, Mazda never put the mill into production, and the RX-8 remains the company's last Wankel-powered model to be offered in showrooms. "We have a dream that one day, this design with a rotary engine will achieve a level that customers will accept," CEO Masamichi Kogai said to AN. Mazda is quite clear that the RX-Vision might never go on sale without a suitable rotary. Although if it does see production, the coupe would likely use a stiffened version of the Miata's chassis, AN reports. Before anyone can place an order, these 50 determined engineers still have a lot of work ahead of them. Related Video:

Best compact SUVs of 2022

Compact SUVs are now the go-to choice for family transportation. Actually, considering how popular they are, they have clearly moved beyond only family duty. With such popularity, though, comes an awful lot of competitors, and it can be difficult to figure out which one might be the best compact SUV for you.  It's important to note that by "compact SUV" we're talking about a specific segment. As we describe in our more comprehensive "Best small SUVs" list, there are also subcompact SUVs that vary widely in size amongst themselves, but are clearly smaller than the SUVs below. Frankly, today's segment of compact SUVs isn't exactly compact — some have more cargo space than vehicles that are considered midsize based on their exterior dimensions. They've all grown considerably over the years. While many lists out there just rattle off every vehicle available in a segment, we thought we'd be a bit more helpful and curate your shopping a bit with the top-recommended choices reviewed by Autoblog. We've included both mainstream and compact luxury SUV choices. Best compact SUVs of 2023 and 2024 2024 Honda CR-V Why it stands out: Best-in-class space; excellent hybrid powertrain; sharp interior style; Honda dependabilityCould be better: No lower-price base trim levels; no sporty or off-road niche models; no plug-in hybrid Read our full 2024 Honda CR-V Review Consider the CR-V the baseline for any compact SUV search, and look extra closely at the superb CR-V Hybrid option. Objectively speaking, it's tough to beat due to its massive cargo capacity, voluminous back seat, strong-yet-efficient engines, well-balanced driving dynamics, competitive pricing and features,  and well-regarded reliability. It's easy to see why it continues to be such a best-seller: for the vast majority of compact SUV buyers, and especially families, it checks every box. That's been the case for many years now, however. The all-new 2023 Honda CR-V changes things up by adding a bit more style and character, particularly in terms of its interior design and how surprisingly enjoyable the Sport and Sport Touring hybrid trim levels are to drive.

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:
