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.

Toyota ready to design more heart-racing Prius

Long praised for its fuel economy and reliability, the Toyota Prius has been no stranger to less-than-flattering remarks about its styling and sense of excitement. In fact, the model is a regular movie punchline. For evidence, see Mark Wahlberg in The Other Guys or, more recently, Ice Cube in Ride Along. Apparently, Toyota President Akido Toyoda is getting the message and is pushing for what's been translated as a more "heart-racing" design for both the Prius and the Camry, the Canadian website Driving says. The Camry and Prius accounted for about a third of Toyota's US sales last year. With the Camry as the best-selling US model for each of the last dozen years, Toyota US head designer Kevin Hunter noted at the Detroit Auto Show last week that the Japanese automaker is looking for a "more emotional" design for the boxy sedan. The Prius redesign may have more constraints, as aerodynamics have to be factored in to ensure top-line fuel economy for the world's best-selling hybrid. Toyota used the Detroit show to show off the FT-1, a concept that many consider a preview of the new Supra. How this "Future Toyota 1" will affect the Prius and Camry redesigns, whenever they appear, remains in question but we like where things are headed.

J.D. Power: Vehicle dependability at all-time high, Lexus and Porsche lead

Each year, J.D. Power and Associates surveys original owners of three-year-old vehicles to find out what kinds of problems they have had experienced over the last 12 months, and then it uses this data to create its annual Vehicle Dependability Study. This means that the models in the 2013 study are 2010 model year vehicles, and J.D. Power rates each make as well as the top individual models based on how many problems were experienced per 100 vehicles (PP100).
Debunking the idea that carryover models are more dependable than new or updated models, the 2013 study found that the average carryover model experienced 133 PP100, while all-new or redesigned vehicles for the 2010 model year had 116 PP100; vehicles that received minor changes fared the best with just 111 PP100. The overall average for all makes was 126 PP100, which is the lowest figure since the findings were first issued in 1989.
