Finalists for 2014 Green Car of the Year announced

The list of finalists for the 2014 Green Car of the Year has been announced, and in a genuinely bizarre twist, there's only one hybrid and no electric vehicles among the five contestants, despite the arrival of cars like the BMW i3 and Tesla Model S. Taking the place of the EVs are a pair of diesels, repping a technology that last won a Green Car of the Year award in 2009, when the Audi A3 TDI took the title. No diesel was in the running for last year's award.
Naturally, both of the diesel finalists are fielded by the Germans - with BMW's 328d and Audi's A6 TDI getting the nod. In the case of the 3 Series, BMW installed a 2.0-liter, turbodiesel, capable of delivering 180 horsepower and 280 pound-feet of torque, while returning 45 miles per gallon on the highway. Audi and its larger, 3.0-liter, V6 turbodiesel produce quite a bit more grunt, with 240 hp and 428 lb-ft of grunt, but net a very impressive 38 mpg on the highway in the A6.
Finalists for this year's awards include two diesels, three gas-powered cars and a plug-in hybrid.

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.

Lexus Eco Challenge rewards schools for clean water, briquette press projects

Teams from one New Jersey high school and one Michigan middle school reversed the old adage by thinking locally and acting globally. And that strategy won them the grand prizes in the most recent edition of the Lexus Eco Challenge. The future is indeed bright. The Toyota luxury-vehicle division gave out a half-million dollars in this year's contest. One $30,000 grand prize was awarded to the Pinelands Eco Scienteers from Little Egg Harbor, NJ, which produced and distributed low-cost briquette presses to rural villages beset by deforestation. The other grand prize went to the E.T. Electrical Team from Byron Center West Middle School in Michigan. That middle-school group raised money to send water filters to Haiti, Kenya and the Philippines. Lexus also awarded eight $15,000 first-place awards, with the winners including high schools from California, Florida, Missouri and Pennsylvania as well as middle schools from Arizona, Michigan, North Carolina and Texas. A special shout out goes to Daniel Boone Area High School in Birdsboro, PA, where students created an educational and public-relations campaign to publicize algae-based biofuels. In all, Lexus has doled out more than $4 million in Eco Challenge awards in seven years. Check out Lexus's press release below. Students Get Dollars and Sense in Lexus Eco Challenge - $500,000 Awarded to Teams Who Learn About Environment and Community Empowerment Two Grand Prize Teams Earn $30,000 Eight $15,000 First Place Awards Given to Innovative High School and Middle School Teams Students Bring Ideas to a Larger Audience and Make a Positive Impact on the World TORRANCE, Calif., (Feb. 24, 2014) – It's a win, win situation! Communities become a better place, and students, teachers and schools have the chance to share $500,000 in scholarships and grants through the Lexus Eco Challenge. This year, the $30,000 Grand Prize winners are the Pinelands Eco Scienteers from Little Egg Harbor, New Jersey, and the E.T. Electrical Team from Byron Center, Michigan. The Lexus Eco Challenge is an educational program and contest that inspires and empowers young people to learn about the environment and take action to improve it. High school and middle school teams nationwide define an environmental issue that is important to them, develop an action plan to address the issue, implement the plan, and report on the results.
