Recharge Wrap-up: Nissan earns Energy Star award, ethanol production forecasts adjusted

The US Energy Information Administration has adjusted its ethanol production forecasts. It predicts an average of 944,000 barrels per day for 2015. That number is up from 2014 production levels of 935,000 barrels per day, but it is lower than last month's projection for 2015, which was 947,000 barrels per day. The EIA forecasts 937,000 barrels per day in 2016, down from its prior forecast of 942,000 barrels. Biodiesel production averaged 83,000 barrels per day last year, with projections of 82,000 for 2015, and 84,000 for 2016. Read more from Ethanol Producer Magazine. Boston Mayor Martin J. Walsh supports the proposed Diesel and Vehicular Emissions Ordinance. The ordinance, filed by City Councilor Stephen Murphy, would require emissions control retrofitting of all pre-2007 vehicles belonging to the City of Boston, as well as those of any contractors it hires. The ordinance also seeks to create a simple city-level standard of enforcing the state's anti-idling laws. "The asthma rate in Boston's neighborhoods continues to climb," says Councilor Murphy. "By further tightening air quality standards, as this ordinance does, we will make Boston's neighborhoods healthier." Read more at DieselNet. The Michigan Blue Economy report profiles Ford for its water-saving sustainability efforts. The report notes that Ford reduced its water use by 61 percent, or 10 billion gallons, from 2000 to 2013 by "cutting the water used in everything from cooling towers to paint operations." As part of its Global Water Management Initiative, Ford has decreased its total water use at its facilities worldwide from 64 million cubic meters per year to 25 million cubic meters.

The automaker received the Sustained Excellence Award for its efforts to reduce energy use and greenhouse gas emissions in its operations. Nissan reduced the amount of energy used to build vehicles by 13 percent in 2014. Energy reduction efforts include switching to LED lighting and developing an environmentally friendly paint process. Nissan also works with schools in Tennessee and Mississippi to help them reduce energy usage. "Since this initiative began in 2012, we've helped about 30 schools make the esteemed Energy Star certification list," says Nissan's John Martin. Read more in the press release below.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

Nissan demonstrates GT-R LM Nismo's radical aero

Nissan took a radical approach in designing its GT-R LM Nismo, turning the usual LMP1 form on its head to create a rather unusual prototype. So why did it take such a drastic approach? In a word: aero. In designing a front-engined, front-drive Le Mans prototype, Nissan was able to free itself from many of the restrictions placed on aerodynamic development. So while the likes of Toyota, Audi and Porsche struggle to create as much downforce as the regulations will allow at the rear of their cars, Nissan is finding boatloads more at the front. It's an innovative approach if we've ever seen one, and you can see and hear the team explain how it all works in this latest video clip above.
