Toyota R&D shows off free piston engine linear generator for future EVs

We often hear how an electric vehicle powertrain architecture allows vehicle designers much more freedom than a traditional ICE powertrain does. With differently shaped battery modules and small electric motors, there are lots of way to put the pieces together. With today's plug-in hybrid technology, engineers still need to put a decent-sized ICE somewhere, but new technology from Toyota could free up the gas-electric vehicle designers of the future. Presented at the recent SAE World Congress in Detroit, the idea from Toyota Central R&D Labs Inc. and involves what is called a Free Piston Engine Linear Generator (FPEG). Think of it as a sort of one-cylinder, two-stroke mini-engine that can work either as a generator (thank to magnets and a linear coil) or to directly drive a vehicle. The current prototype is a 10-kW unit that Toyota say would provide enough power to get a B- or C-segment electric vehicle up to highway speeds (75 miles per hour) when paired up to offer 20 kW. Pairing the FPEGs is also important to minimize vibrations. One system tested by Toyota had a 42 percent thermal efficiency, but the engineers are working to improve the overall efficiency even further. You can watch an animated video of the piston in action here (click on "Outline") and see the SAE papers here and here. More technical details are available at Green Car Congress.

Automakers not currently promoting EVs are probably doomed

Okay, let's be honest. The sky isn't falling – gas prices are. In fact, some experts say that prices at the pump will remain depressed for the next decade. Consumers have flocked to SUVs and CUVs, reversing the upward trend in US fuel economy seen over the last several years. A sudden push into electric vehicles seems ridiculous when gas guzzlers are selling so well. Make hay while the sun shines, right? A quick glance at some facts and figures provides evidence that the automakers currently doubling down on internal combustion probably have some rocky years ahead of them. Fiat Chrysler Automobiles is a prime example of a volume manufacturer devoted to incremental gains for existing powertrains. Though FCA will kill off some of its more fuel-efficient models, part of its business plan involves replacing four- and five-speed transmissions with eight- and nine-speed units, yielding a fuel efficiency boost in the vicinity of ten percent over the next few years. Recent developments by battery startups have led some to suggest that efficiency and capacity could increase by over 100 percent in the same time. Research and development budgets paint a grim picture for old guard companies like Fiat Chrysler: In 2014, FCA spent about $1,026 per car sold on R&D, compared with about $24,783 per car sold for Tesla. To be fair, FCA can't be expected to match Tesla's efforts when its entry-level cars list for little more than half that much. But even more so than R&D, the area in which newcomers like Tesla have the industry licked is infrastructure. We often forget that our vehicles are mostly useless metal boxes without access to the network of fueling stations that keep them rolling. While EVs can always be plugged in at home, their proliferation depends on a similar network of charging stations that can allow for prolonged travel. Tesla already has 597 of its 480-volt Superchargers installed worldwide, and that figure will continue to rise. Porsche has also proposed a new 800-volt "Turbo Charging Station" to support the production version of its Mission E concept, and perhaps other VW Auto Group vehicles. As EVs grow in popularity, investment in these proprietary networks will pay off — who would buy a Chevy if the gas stations served only Ford owners? If anyone missed the importance of infrastructure, it's Toyota.

Car technology I'm thankful and unthankful for

The past few years have seen a surge of tech features in new vehicles — everything from cloud-based content to semi-autonomous driving. While some of it makes the driving experience better, not all tech is useful or well thought out. Automakers who are adept at drivetrains, ride quality and in-cabin comforts often fail at infotainment interfaces and connectivity. From testing dozens of vehicles each year and in the spirit of gratitude, here are three car tech features I'm thankful — and a trio I could live without. Thanks Connected search: This seems like a no-brainer since everyone already has it on their smartphones, but not all automakers include it in the dashboard and as part of their nav systems. The best ones, such as Toyota Entune, leverage a driver's connected device to search for a range of services and don't charge a subscription or require a separate data plan for the car. I also like how systems like Chrysler Uconnect use Yelp or other apps to find everything from coffee to gas stations and allow searching via voice recognition. Apple CarPlay and Android Auto: It took two of the largest tech companies to get in-dash infotainment right. While they have their disadvantages (you're forced to use Apple Maps with CarPlay, for example), the two smartphone-integration platforms make it easier and safer to use their respective native apps for phoning, messaging, music and more behind the wheel by transferring a familiar UI to the dashboard — with no subscription required. Heated seats and steering wheels: I really appreciate these simple but pleasant features come wintertime. It's easy to get spoiled by bun-warmers on frosty mornings and using a heated steering wheel to warm the cold hands. I recently tested a 2018 Mercedes-Benz E400 Coupe that also had heated armrest that added to a cozy luxury experience. Bonus points for brands like Buick that allow setting seat heaters to turn on when the engine is remotely started. No thanks Automaker infotainment systems: Automakers have probably poured millions into creating their own infotainment systems, with the result largely being frustration on the part of most car owners. And Apple CarPlay and Android Auto coming along to make them obsolete. While some automaker systems, such as Toyota Entune and FCA's Uconnect, are easy and intuitive to use, it seems that high-end systems (I'm looking at you BMW iDrive and Mercedes-Benz COMAND) are the most difficult.
