Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

Nissan, Honda and Mitsubishi will share EV components and AI research

TOKYO — Japanese automakers Nissan and Honda say they plan to share components for electric vehicles like batteries and jointly research software for autonomous driving. A third Japanese manufacturer, Mitsubishi Motors Corp., has joined the Nissan-Honda partnership, sharing the view that speed and size are crucial in responding to dramatic changes in the auto industry centered around electrification. A preliminary agreement between Nissan Motor Co. and Honda Motor Co. was announced in March. After 100 days of talks, executives of the companies evinced a sense of urgency. Japanese automakers dominated the era of gasoline engines in recent decades but have fallen behind formidable new players in green cars like Tesla of the U.S. and ChinaÂ’s BYD. “Companies that donÂ’t adapt to the changes cannot survive,” said Honda Chief Executive Toshihiro Mibe. “If we try to do everything on our own, we cannot catch up.” Nissan and Honda will use the same batteries and adopt the same specifications for motors and inverters for EV axles, they said. By coming together in what Mibe and counterpart at Nissan, Makoto Uchida, repeatedly called “making friends” to achieve economies of scale, the companies plan more strategic investments in technology and aim to cut costs by boosting volume. Each company will continue to produce and offer its own model offerings. But they will share resources in areas like components and software development, where “making friends” will be a plus, Mibe and Uchida told reporters. They declined to say whether the friendship will extend to a mutual capital ownership, while noting that wasnÂ’t ruled out. The two companies also agreed to have their model lineups “mutually complement” each other in various global markets, including both internal combustion engine vehicles and EVs. Details on that are being worked out, the companies said. Honda and Nissan will also work together on energy services in Japan. Under ThursdayÂ’s announcements, Mitsubishi will join as a third member. Toyota Motor Corp., JapanÂ’s top automaker, is not part of the three-way collaboration. Although Honda and Nissan have very different corporate cultures, it became clear, as their discussions on working together continued, their engineers and other workers on the ground have a lot in common, Uchida said. “Speed is the most crucial element, considering our size,” he added.

2019 Toyota Avalon vs. full-size sedans: How they compare on paper

Full-size sedans aren't exactly in great demand at the moment, and at least one of the vehicles in this comparison has been rumored to be on the endangered species list. Yet, we've just had our first drive in the 2019 Toyota Avalon, and if anything has a chance of rejuvenating the segment a bit, it's an all-new version of what has long been the segment's benchmark. To see how the new Avalon compares, we've put together the below spreadsheet featuring the Avalon's primary apples-to-apples rivals, the Buick LaCrosse and Chevy Impala. We also included the Nissan Maxima, which is comparable in price, sales and non-luxury badge, and which offers the sort of increased driver engagement promised by the new Avalon XSE and Touring trim levels. We also included the outgoing Avalon for reference as well as that car's luxury cousin, the Lexus ES, which can definitely be cross-shopped with the luxuriously trimmed Avalon Limited. You can use our Compare Cars tool to create your own comparison, such as one featuring the rear-wheel-drive Chrysler 300, Dodge Charger or even Kia Stinger. Alright, enough chit chat. On to the spreadsheet. Performance and fuel economy The GM sedans may come standard with four cylinders, including a mild hybrid system in the LaCrosse, but puh-lease. The V6 is the name of the game in this segment, with outputs now surpassing the 300-horsepower mark. The LaCrosse is the horsepower and torque champ, though it also weighs a bit more than the new 2019 Avalon, so acceleration is likely to be comparable. The Impala weighs a lot more and has only a six-speed automatic, so despite having a wee bit more power, one should expect it to be pokier (not a good sign for a car rumored to be on the chopping block). One would expect the Maxima's 300 hp and lowest curb weight to result in the quickest acceleration, but then it's also strapped to a CVT, which despite being better than ever, is still a CVT. Things get worse for Chevy when you consider the Impala's base four-cylinder gets the same 25 mpg combined as the Avalon's V6 — once again a segment best. Now, should you really prioritize fuel economy, the 2019 Toyota Avalon Hybrid really stands out with a 43 mpg rating (or 44 with the base XLE trim) that bests the outgoing Avalon Hybrid. Honestly, after driving this new Hybrid, it actually seems like it would be the best bet for most buyers. There's sufficient power, and it only costs $1,000 more than the comparable V6 version.
