Mazda previews straight-six, affirms upcoming crossover with Toyota hybrid system

Buried in Mazda's generally bleak second-quarter earnings report were a few juicy nuggets of news. Though the company had an operating loss of $502 million and sales are down 21 percent in part due to the COVID-19 pandemic, the Hiroshima-based firm has big plans for the future. Enthusiasts and environmentalists alike should take note. Firstly, Mazda showed an image of its upcoming straight-six engine. Essentially, it's the SkyActiv four that powers all of Mazda's current lineup, but with two additional cylinders. Unsurprisingly, the company says that it can be engineered to fit any of the current SkyActiv guises — the standard octane-variable gasoline powered G, the diesel D, and the sparkless-ignition X. The big six will pair with a new eight-speed automatic and can be combined with either a plug-in or 48-volt mild hybrid system, promising big power and efficiency. Reassuringly, Mazda says it's committed to offering this six in a rear-wheel-drive platform, which will underpin the 6 sedan's successor, as well as a midsize SUV. Both the platform and powertrain are said to be compatible with all-wheel-drive layouts as well. Which brings us to the second bit of news. Mazda also pictured a four-cylinder engine with hybrid technology. The financial report confirmed that Mazda will employ  Toyota's wildly successful hybrid system in an upcoming SUV. It's not that Mazda is taking advantage of Toyota's free access to all its hybrid patents until 2030. Mazda and Toyota have a capital tie-up and are nearing completion on a $2.3 billion joint-venture factory in Alabama with a 300,000-vehicle annual capacity. According to the Huntsville Business Journal, the firms have hired 750 employees so far, with room for 3,250 more. In return, Mazda will launch a European compact based on Toyota's Yaris Hybrid. The move is necessary for Mazda, which has lagged behind in electrification and in meeting the fleet emissions requirements in the European market. In return, by 2022, Mazda may even share the inline-six engine with Toyota and Lexus. While the hybrid crossover and compliance with EU rules will no doubt help the environment, we not-so-secretly hope that these strategies will keep Mazda profitable enough to bring that straight-six, rear-drive sports sedan to market.

Bibendum 2014: Former EU President says Toyota could lose 100,000 euros per hydrogen FCV sedan

Pat Cox does not work for Toyota and we don't think he has any secret inside information. Still, he's the former President of the European Parliament and the current high level coordinator for TransEuropean Network, so when he says Toyota is likely going to lose between 50,000 and 100,000 euros ($66,000 and $133,000) on each of the hydrogen-powered FCV sedans it will sell next year, it's worth noting. That was just one highlight of Cox's presentation at the 2014 Michelin Challenge Bibendum in Chengdu, China today, which addressed the main problem of using more H2 in transportation: cost. The EU has a tremendous incentive to find an alternative to fossil fuels, since Europe today is 94 percent dependent on oil for its transportation sector and 84 percent of that 94 percent dependency is imported oil. The tab for that costs the EU a billion euros a day, Cox said, on top of the environmental costs. To encourage a shift away from petroleum, European Directive 2014/94 requires each member state to develop national policy frameworks for the market development of alternative fuels and their infrastructure. For the member states that choose to fulfill 2014/94 by developing a hydrogen market – and to be clear, Cox said, it's not an EU diktat that they do so, since a number of other alternatives are also allowed – the aim is to have things in place by the end of 2025. The plans don't even have to be submitted until the end of 2016. The long lead time is due to a quirk in a hydrogen economy. In hydrogen infrastructure, "the first-mover cost is not the first-mover advantage, but the firstmover disadvantage." – Pat Cox In deploying a hydrogen infrastructure, Cox said, "the first-mover cost is not the first-mover advantage, but the first-mover disadvantage, and high risk." That's why the EU and member states will financially support the early stages, but everyone agrees that "if this is to work, it will have to be ultimately and essentially a commercially viable and commercially driven infrastructure roll-out." Since 1986, European Union research programs have spent 550 million euros on hydrogen-related and fuel-cell-related research, including methods of hydrogen storage and distribution as well as improved fuel cells vehicles, Cox said. Expensive problems remain to be solved. At a conference in Berlin, Germany this past summer, Cox said, the unit cost of the refueling stations was identified as the main problem.

This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.
