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.

European car sales up 8% in February

Three weeks ago an analyst increased projections for European car sales this year, expecting them to climb three percent compared to last year instead of 2.7 percent. That number is a postive sign after years of hard times but it turns out February was especially good, overall European sales climbing eight percent on a wave of southern European recovery and discounts - and this comes after five months of gains including January's 7.2-percent jump over the year before.
The only country of Europe's five largest markets to post a decline was France, just as it did in January, Germany, the UK and Italy posting solid double-digit numbers, Spain rocking the charts with an 18-percent increase because of a government program to encourage trade-ins.
The only brand to miss the wave was Volkswagen, dropping 0.8 percent as it watched the double-digit growth at sister brands Audi, Seat and Skoda lift the Volkswagen Group sales up by seven-percent. Peugeot overcame flat sales at Citroën to improve the group by 3.5 percent, BMW and the Mercedes-Benz/Smart combo rose by four percent, the Fiat group jumped 5.8 percent, Ford was up 11 percent, the Renault Group 11.5 percent, General Motors 12 percent and the Toyota clan by 14 percent.

Toyota officially outsells GM, VW through first three quarters

When it comes to global vehicle deliveries, the term "Big Three" doesn't apply to Ford, Chrysler and General Motors, but instead Toyota, GM and Volkswagen - in that order - through the third quarter of 2013. Toyota sold 7.41-million vehicles through the third quarter and is on track to deliver more vehicles this year than GM and VW, which sold 7.25-million and 7.03-million, respectively, through the same period, Bloomberg reports.
During the third quarter, from July to September, Toyota's 2.5-million deliveries helped to push it higher than its closest competitors this year. In that period, GM delivered 2.4-million vehicles while VW posted 2.33-million deliveries.
Part of the reason behind Toyota's and other Japanese automakers resurgence globally is the weakened yen, which can be attributed to policies made by Prime Minister Shinzo Abe since he took office in December 2012. Many refer to those monetary easing policies as 'Abenomics,' which has led some, such as Ford, to call Japan a currency manipulator and is a big reason why the US is lobbying to oppose Japan's entry into the Trans-Pacific Partnership (TPP).
