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.

Is your new-car warranty good at the race track?

We've all heard the horror stories. Your buddy knows a girl that was dating a guy whose best friend's brother once broke his brand-new, recently purchased performance car while making runs at a drag strip or laps at a track day, and the manufacturer wouldn't cover the repair under warranty. True story? Urban legend? Complete crap? Yes, no, maybe. One thing's for sure: Automotive warranties have always come with caveats. In 1908, an ad in the Trenton Evening Times clearly stated: "All Ford Cars Guaranteed for One Year." Although it changed over time, by 1925 the Ford New Car Guarantee only covered 90 days on material and 30 days on labor, and it clearly stated that that there was "No guarantee whatever on Fan Belts, Glass, Bulbs, Wiring, Transmission, Bands, Hose Connections, Commutator Shells, Rollers, Spark Plugs or Gaskets." Whether or not Ol' Henry would pay to fix your Model T if you broke it shaving a tenth off your lap time at the local board track seems to be lost to history. We're guessing no. But what about today? Do new-car warranties in 2017 cover cars when they are driven on race tracks? We researched the warranties of 14 auto brands to find out, and the answer is yes, no, maybe, depending on the brand, in some cases the model, and whether or not your car is modified from stock. Acura has been out of the high-performance car game for a number of years, but jumps back into the party in 2017 with its hybrid-powered $173,000 NSX supercar. And Acura's warranty, as well as Honda's, clearly states that it does not cover "the use of the vehicle in competition or racing events."

No question," he told us. "However, if the car is modified, say with slick tires or other components that would put higher stresses on the vehicle's parts and systems, then we would have to investigate the circumstances further." Marie went on to say the same would be true for any Acura model or Honda vehicle, including the new 2017 Honda Civic Si. This became a common theme. Chevrolet actually started this practice with the fifth-generation Camaro on the high-performance ZL1 and Z/28 models.

Recharge Wrap-up: Honda FCV Concept comes to Detroit, Toyota seeks young green energy fellows

Honda will bring its FCV Concept to the 2015 North American International Auto Show in Detroit in January. The hydrogen-powered concept made its Japanese debut in November, and will now make its way to North America for the first time. The FCV concept improves upon the design of the FCX Clarity with a more striking appearance and roomier interior. Its smaller powertrain packaging means more space for people, and the FCV Concept seats five passengers. Honda also expects the next-generation fuel-cell car, which is scheduled to go on sale in Japan in March 2016, to cost less and have a range of over 300 miles. Read more in the press release below. The Mercedes-Benz B-Class Electric Drive has been awarded an environmental certificate from the TUV Sud technical inspection authority. The certificate is based not just on the vehicle's operation, but the entire lifecycle of the car, including production and recycling. The B-Class Electric Drive produces 24 percent less CO2 over its lifecycle than the Mercedes-Benz B180 when using the EU electricity mix, and 64 percent less when powered by hydroelectricity. Mercedes credits not just the use of electricity, but also the car's energy management system - such as its radar-based regenerative braking - for its carbon reductions.

One of its stops will have a wireless charging station where the bus will recharge for six to seven minutes before continuing on its route again. The charger is located under the road surface and the bus positions itself above it to charge inductively. About $1.3 million will come from the Swedish Energy Agency to fund the test project, which could save up to 90 percent of fuel costs. If expanded to a fleet of 2,000 buses, it could save up to 13 million gallons of fuel each year. Read more at Green Car Congress, and in the press release below. Sandia National Laboratories and Linde are teaming up to expand hydrogen fueling infrastructure. The two groups have signed an agreement to research and develop new hydrogen stations, as well as ways to make fuel cell vehicles more desirable for consumers. They are looking at ways to incorporate hydrogen into existing fuel stations where possible, and make sure that it is able to be done safely.
