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.

Subaru to stop building Camry for Toyota in the US

It was back in 2007 that Subaru of Indiana Automotive, under contract from Subaru minority shareholder Toyota, built the first Toyota Camry at its plant in Lafayette, Indiana. Rumblings of the end of that contract work have been around for a while, as Subaru talked of expanding capacity to build more units and add a line for the Impreza, and Toyota talked of moving Camry production to its Georgetown, KY plant. The news was official internally last November when SIA Executive Vice President Tom Easterday told the Louisville Courier-Journal that Camry production would end. Now, Automotive News reports that both automakers have admitted publicly that the end will come in 2016.
SIA currently has a 170,000-unit capacity devoted to the home-brand Legacy and Outback models, while a $400-million expansion increases that to 300,000 units to prepare the facility for Impreza production in two years. Freeing up the 100,000 units of production devoted to the Camry means a 400,000-unit capability, which is far more than Subaru needs at the moment, but the Toyota exit will allow it to expand any way it sees fit. Subaru has said it will absorb the workers on the Camry line and no jobs will be lost, the mayor of Lafayette saying the development could change the timetable for the expansion.

North American production of foreign marques to jump in 2014

Wards Auto has released its North American Light Vehicle Production Forecast for 2014, and the report predicts foreign manufacturers will increase production on the continent some 3.9 percent by 2014. If accurate, that should see 123,000 additional cars, trucks and vans produced in North America, swelling the total number of units produced both by domestic and foreign manufacturers to 16.9 million light vehicles from a projected 15.6 million in 2013. Much of the increase can be attributed to the fact that Toyota intends to produce another car at its Blue Springs, MS plant as well as a new Lexus model at its Georgetown, KY facility in a year's time.
Likewise, Volkswagen intends to move production of a currently imported model to its plant in Puebla, Mexico. Daimler, Honda, Nissan and Mazda also plan to build additional models on North American soil for the first time. Around two-thirds of the new North American manufacturing will take place in Mexico, helping the country soak up a full 20 percent of the content's automotive production for the first time.
