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.

8 things you should know about the Lexus LC 500h powertrain

Lexus unveiled the LC 500h today in The Netherlands, and I got to take a look inside its new hybrid system. On one hand it seems like a box of magic – it combines two seemingly incompatible transmission types into one package. But that's also the ingenious simplicity of the thing. We don't have all of the details on how it all works yet, but here's a rundown of the high points.Efficient business in front, low-key party in the back. What makes it all work is the mullet of transmissions. For the new hybrid transmission, Lexus used the Toyota Hybrid Synergy Drive/Lexus Hybrid System – which consists of an e-CVT with a planetary gearset and two electric motors (one for charging the battery, the other for motivation and regen) – and grafted a conventional four-speed automatic onto the back. The two units actually coexist in one package, with the e-CVT making things efficient and the automatic expanding the capabilities. So at the low end, the system can deliver more torque, and the engine can also run at lower rpm on the highway. It's all thanks to those fixed gear ratios, and it's surprisingly simple.Except it's not that simple. This is where the virtual gear ratios come in. Like current Lexus hybrids, the system has ratios it can call up with the e-CVT. In this case, there are six virtual ratios to complement the four real physical ratios, for a total of 10 "gears" at the transmission's disposal. (Not coincidentally, the V8 LC 500 coupe has a 10-speed automatic.) One of the four fixed gears is always engaged when the car is moving, so the 10 ratios come about from combinations of what the e-CVT in front and the automatic in the back are doing. In other words, all 10 ratios are variations on the four fixed gear ratios, which means that all 10 gears could be considered virtual.It won't use all the gears all the time. In Eco mode, the car will start off on electric power and skip the first couple of "gears." When it's set to Sport or Sport +, the engine will be engaged from a stop and the transmission will select the lowest ratio. The sportier modes will also ignore the top couple of gear ratios.It can drive faster with the engine off. In a Lexus GS 450h with the Lexus Hybrid System, for example, at speeds above 62 mph or so the engine has to start up. This is because something needs to take up some slack from the battery-charging motor-generator or else it will start spinning too quickly.

Lexus jumps head first into turbocharging with its 2015 NX 200t

If Lexus is going to stay competitive, it needs to turbocharge sooner rather than later.
If there's anything that Lexus is experienced with, thanks in large part to its corporate parents at Toyota, it's hybrid powertrains. The automaker has hybridized tiny little four-cylinder engines, massive honkin' V8s and everything in between. So synonymous are hybrids and Lexus that it would be a shock to see a brand-new model released without an accompanying version with blue badging and a little "h" appendage to its name.
