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.

2016 Green Truck of the Year, Commercial Green Car of the Year finalists

Not only are commercial-grade haulers getting more green love lately, they're getting more different kinds of green love. The 2016 Green Truck of the Year, the second time the award has been handed out, is being decided by judges from Green Car Journal and the San Antonio Auto & Truck Show. This year the award is joined by the new 2016 Commercial Green Car of the Year, which crowns one of the little vans increasingly used by small business as cargo and delivery vehicles. The Green Truck of the Year finalists are the Chevrolet Colorado Duramax (pictured), Ford F-150, GMC Canyon Duramax, Nissan Titan XD, and Toyota Tacoma. The first three of those were on last year's list, but since they are completely new or upgraded for 2016 - Ford with its all-aluminum body, the General Motors twins with the new diesel Duramax engine - they qualify for entry again. The Ram 1500 EcoDiesel won last year. The Commercial Green Car finalists are the Chevrolet City Express, Ford Transit Connect, Mercedes-Benz Metris, Nissan NV200, and Ram ProMaster City. You can read more details in the presser below, and the awards will be announced in San Antonio sometime during the show from November 19-22. San Antonio Auto & Truck Show Announces 2016 Green Truck of the Year and Commercial Green Car of the Year Finalists SAN ANTONIO, Oct. 22, 2015 /PRNewswire/ -- Green Car Journal and the San Antonio Auto & Truck Show have announced finalists for the 2016 Green Truck of the Year™ and 2016 Commercial Green Car of the Year™ awards. The Green Truck of the Year™ nominees are the Chevrolet Colorado Duramax, Ford F-150, GMC Canyon Duramax, Nissan Titan XD, and Toyota Tacoma. Vying for the all-new 2016 Commercial Green Car of the Year™ award are the Chevrolet City Express, Ford Transit Connect, Mercedes-Benz Metris, Nissan NV200, and Ram ProMaster City. "Over the past few decades, new car models have benefitted from design and technology improvements that have brought higher fuel efficiency and greater levels of environmental compatibility," said Green Car Journal and CarsOfChange.com Editor and Publisher Ron Cogan. "With models like these ten deserving finalists, we're witnessing the pickup and light commercial vehicle field enjoying the same attention." The new Commercial Green Car of the Year™ award is part of an expanded awards program presented at this year's 2015 San Antonio Auto & Truck Show.

Ford tops GM in US vehicle sales in May, driven by fleets

DETROIT - Ford, bolstered by heavy sales to fleet customers, surpassed General Motors in US new vehicle sales in May, according to figures reported Thursday. Ford said May sales rose 2.2 percent from a year ago to 241,126 units. GM sales dropped 1.3 percent to 237,364. GM said it had been trimming sales of heavily discounted vehicles to car rental companies. Such fleet sales made up about 19 percent of its total sales in May. Ford's fleet sales rose 8.4 percent, representing more than 34 percent of total sales. The industry average is around 20 percent. Analysts had expected mixed results for the industry, with sales likely propped up by heavy discounts. Fiat Chrysler Automobiles said May sales dipped 0.9 percent to 193,040. Toyota's US sales dropped 0.5 percent to 218,248. Nissan said US sales in May rose 3.0 percent, to 137,471. After demand fell in March and April, analysts estimated May sales at just over 1.5 million. The seasonally adjusted annual rate of sales in May was estimated at 16.8 million to 16.9 million vehicles, about the same as April. A year earlier, sales stood at 17.55 million vehicles. Early reports indicated that sales over the three-day Memorial Day weekend were helped by heavy discounts. "While demand for new vehicles is still relatively strong, it's a bit of smoke and mirrors," said Jessica Caldwell, executive director of industry analysis at Edmunds, the car shopping website. Manufacturers and dealers "really pushed the deals over the holiday weekend to prop up their May numbers," she said. "Incentives were up sharply, and it seems automakers are putting more cash on the hood to nudge car shoppers to buy versus lease." General Motors dealers were offering discounts of up to $12,000 on the full-size Chevrolet Silverado pickup, while some dealer discounts on Ford Motor Co's F-series pickups were more than $10,000 on 2017 models and more than $14,000 on leftover 2016 models. The 2017 model year started eight months ago. Reporting by Paul LienertRelated Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
