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.

Recharge Wrap-up: 1M Lexus hybrids, Best Buy Geekmobile goes Prius

Cummins is developing a plug-in hybrid system for heavy trucks. Its plug-in system for Class 6 trucks (those with a gross vehicle weight between 19,000 and 26,000 pounds) is expected to improve fuel economy by 50 percent. Funded in part by a $4.5-million grant from the US Department of Energy (DOE), the system will use a battery pack and some form of range extending internal combustion engine. The system will employ various drive cycles in order to help commercial fleets save fuel based on their needs. Read more at Gas2. German automaker Borgward, LG Chem, Bosch, and software firm SAP have joined forces to form an electric mobility partnership. Borgward recently revived its brand with a new model, the BX7. Borgward has also announced that two other models, the BX5 and BX6, will be available as plug-in hybrids. SAP will provide software services, and LG Chem will supply battery technology to Borgward. Bosch will supply and help develop a number of components for Borgward cars. Read more at Inside EVs. Lexus has sold its millionth hybrid. The luxury automaker began selling hybrids with the electrified RX in 2005, and the millionth hybrid was a NX 300h sold to a customer in Milan, Italy. "This is my first Lexus," says the customer of that vehicle in a Lexus release, Aldo Pirronello. "... and I am honored to celebrate this important milestone with Lexus!" Lexus currently sells 10 hybrid models worldwide. Read more from Lexus. Best Buy's Geek Squad is switching from Volkswagen Beetle Geekmobiles to the Toyota Prius C.

Toyota Prius remains best-selling vehicle in California, wireless charging tests underway

About one in every nine new cars in the US are sold in the California. If we're just looking at the four Toyota Prius hybrid variants, then the number becomes closer to one in three. Tesla Model S battery-electric vehicle sales? Try one in 2.7. For the second straight year, the Prius was the best-selling car in the Golden State. Toyota sold 69,728 Priuses there, almost a third of the more than 234,000 sold in the US in 2013. Prius sales in California alone were up almost 13 percent. And Toyota's ready to build upon that momentum with a new version of the Prius Plug-in Hybrid, saying that it's testing a wireless recharging system in Japan's Aichi Prefecture and will start similar tirals stateside later this year. We'll make the wild prediction that some of those tests, which involves magnetic resonance, will be in California. Meanwhile, Tesla's numbers were, in their own way, were more impressive. The California-based automaker sold 8,347 of its Model S units in the Golden State out of about 22,300 nationwide in 2012, Bloomberg News reports. In all, advanced-powertrain vehicles accounted for 9.3 percent of California new-vehicle sales, compared to 3.8 percent for the country, Bloomberg says, citing Hybrid Cars and Baum & Associates. Check out Toyota's press release on its California sales below. Prius Medals In The Golden State Toyota Prius is best-selling vehicle line in California Wireless charging testing for Prius Plug-in TORRANCE, Calif., Feb. 18, 2014 /PRNewswire/ -- The Prius took home the gold in 2013 as the most popular vehicle-line in California for the second year in a row. The Prius Family (Prius Liftback, Prius v, Prius c and Prius Plug-in) took the podium in both 2012 and 2013 as the best-selling California vehicle name plate. 69,728 drivers hit the road in 2013, according to the California Auto Outlook Report, while 61,893 Californians joined the family in 2012. In the Golden State, the Prius Family outsells all other hybrid competitors combined. California drivers lead the country in adoption of vehicles powered, either wholly or partially, by electricity. 9.3% of vehicles sold in the state run on some form of electricity, according to the report. But despite the growing number of hybrid competitors, Toyota's hybrid leadership remains unmatched. In fact, one out of every two hybrids in California carries the Prius name plate.
