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.

Who sold the most small/midsize pickups in 2012? PickupTrucks.com investigates that, too

PickupTrucks.com has taken another look at the sales of its favorite vehicle bodystyle as part of an ongoing series. According to registration data from R.L. Polk, the Toyota Tacoma easily took the crown as America's best-selling mid-sized pickup, with 133,477 units rolling into new homes in 2012. For comparison, the second-place Nissan Frontier only saw 50,566 registrations.
We feel compelled to point out that before Ford pulled the plug on its ancient Ranger, the company was moving some 75,000 units per year. That number had shriveled to 15,662 by 2012, which was still enough to surpass the Honda Ridgeline. Interestingly enough, one person brought home a brand-new Hummer H3T as well. But mid-sized trucks represent only a fraction of total pickup sales. Dealers sold a total of 241,471 midsizers last year compared to 988,326 half-tons.
That segment was dominated by General Motors with 533,814 sales followed by Ford at 478,204. Ram Trucks trailed behind in third with 241,204 units with Toyota close behind at 229,769. Nissan, meanwhile, remains a distant fifth. Head over to PickupTrucks.com for a closer look at the breakdown in each segment.

Toyota, Mercedes, BMW top automakers included in List of Best Global Brands

Interbrand, a consultancy firm, has published its 13th annual list of the best global brands. Besides seeing some shakeups at the top - Apple and Google unseated Coca-Cola (a company that has dominated the survey since its birth), the 100-item list features 14 automakers, most of which enjoyed double-digit gains in brand value.
Toyota managed to retain its spot as the study's top automaker. It finished the survey in 10th position overall (the same as last year), despite a 17-percent improvement in its brand value, from $29.33 billion to $35.34 billion. Mercedes-Benz, BMW and Honda all made the top 20, at 11th, 12th and 20th place, respectively. Hopping a ways down the list, we come across Volkswagen in 34th place, up from 39th in last year's study, with a brand value of $11.12 billion, a 20-percent improvement over 2012. Ford and Hyundai round out the automakers in the top 50, at 42 and 43.
Porsche made the largest year-over-year gain of any automaker, with its brand value increasing 26 percent to $6.47 billion. Chevrolet meanwhile, cracks the list for the very first time at 89th place. As Interbrand notes, Chevy's inclusion is notable because of the sheer number of vehicles it moves for General Motors and its recent push in developing markets. The final interesting note on this survey is the position of an automaker that takes its name and logo more seriously than perhaps any other - Ferrari. The Italian exotic manufacturer finished 98th out of 100, with just $4.01 billion in brand value, a six-percent improvement over 2012.
