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.

The pre-race and first in-race report from Le Mans

The 2013, 90th anniversary edition of the 24 Hours of Le Mans has begun, tragedy marking the opening laps with the death of Allan Simonsen. We're at the track now as a guest of Audi and plan to stay through the evening, and even we haven't been able to find out what caused the accident - the only video is from just after the incident, and beyond the statement from ACO there's been no more news. The Aston Martin in the LM GTE Am class and its all-Danish drivers had taken pole in its class and was one of the favorites to win.
The pre-race report will come first, and even thought we can't spoil the race because we're only five hours into it at the time of writing, we'll put all of the news at the end in case you don't even want the updates.

Ford barely edges surging Chrysler for Canadian sales crown in best year ever

The auto industry in the US showed strong results through much of 2014 with sales regularly growing year-over-year for many brands. That same trend carried over in the Great White North, as well. Canada posted its best numbers ever with 1.85 million units sold, up about 100,000 vehicles over 2013. The country nearly had a new market leader, too. The big winner among our neighbors to the north in 2014 was Ford with 291,951 vehicles sold, up 3 percent from 2013, according to Reuters. That success also handed the company the sales crown for the fifth consecutive year. In large part, the strong result came from the company's popular trucks, which represented about 80 percent of overall sales. "Ford moved into the number one position in September and didn't look back," said a note to clients by DesRosiers Automotive Consultants quoted by Reuters. However, the Blue Oval didn't exactly take an overwhelming lead for the year. The company nearly had to hand over the sales trophy to FCA after the company rallied in the latter part of the year. The Italian-American conglomerate had its best results ever to nip at the Ford's heels and move 290,004 units for 2014, a 12-percent improvement from last year. Jeep especially helped the bottom line with over 50-percent growth, according to Reuters. Only two other brands were able to break the 200,000-vehicle barrier in Canada for 2014. General Motors came in third place overall with 249,800 sales, up 6.3 percent. The combined Toyota and Lexus also barely jumped the hurdle with 200,851 units moved, a 2.8 percent improvement.
