Jay Leno burns rubber in Tesla Model S

Jay Leno has a pretty big soft spot for alternative-fuel vehicles. From his steam-powered relics to his beloved Chevrolet Volt, the comedian's automotive interests are nothing if not varied. In the latest episode of Jay Leno's Garage, Tesla Chief Designer Franz von Holzhausen stops by the Big Dog Garage to show off his company's new Model S. Jay gets a closer look at the five-door EV's interesting touchscreen controls, expansive moonroof and yes, even the third-row jump seats, before taking to the road. The clip explains why Tesla eschewed the chunky standardized EV charger for a more svelte unit and how the company managed to serve up impressive aerodynamics without sacrificing styling.
Leno takes the time to whir the Model S around the greater Los Angeles area before hopping on the freeway for a quick spin. This particular model features the largest battery pack available, which gives the Model S a total range of around 300 miles. Check out the clip below for a closer look.

Tesla adds free titanium underbody shields to Model S to prevent fires

Following a garage fire incident with a Model S EV last year, Tesla Motors quickly sent out an over-the-air software update to adjust how the car charges. Following two on-road fires caused by road debris that struck the underside of different Model S EVs (one in Washington State and the other in Tennessee), Tesla basically said, that it was a random thing, and the car is perfectly safe. The company later sent out a software update to have the car ride a bit higher at highway speeds. Today, Tesla is offering a more substantial solution. Tesla CEO Elon Musk has announced that all Model S EVs built since March 6 have a stronger triple underbody shield that should "bring this [fire] risk down to virtually zero." The company conducted 152 tests using, "every worst case debris impact we can think of, including hardened steel structures set in the ideal position for a piking event, essentially equivalent to driving a car at highway speed into a steel spear braced on the tarmac" and is now confident that there's basically nothing that can break through the new barriers. As you can see here, the shields prevent a concrete block, a three ball tow hitch and a steel alternator from puncturing the car's underside. The new shields should "bring this [fire] risk down to virtually zero." Any Model S owner who wants the new triple shield can ask for it, and even if they don't ask, the structure will be installed whenever the car is next in for service. The three layers of the shield include a rounded, hollow aluminum bar, a titanium plate and "a shallow angle, solid aluminum extrusion." The new shields, "only have a 0.1 percent impact on range and don't affect ride or handling," Musk writes, which means there's no reason for Model S owners not to get the upgrade. You can read all of Musk's explanation below. Tesla Adds Titanium Underbody Shield and Aluminum Deflector Plates to Model S By Elon Musk, Chairman, Product Architect & CEO In 2013, two extremely unusual Model S collisions resulted in underbody damage that led to car fires. These incidents, unfortunately, received more national headlines than the other 200,000 gasoline car fires that happened last year in North America alone. In both cases, the occupants walked away unharmed, thanks to the car's safety features. The onboard computer warned the occupants to exit the vehicles, which they did well before any fire was noticeable.

Recharge Wrap-up: Tesla factory loses power, plant genes modified for biofuel

Tesla's Fremont factory was shut down on Friday morning when a crane knocked out power to the facility. No injuries were reported and Tesla didn't say what effect the outage would have on production. Read more from SFGate or from CNBC. Researchers have genetically modified a plant for lower-viscosity seed oil to make biodiesel. With the viscosity of many plant-based oils being too high for use in modern high-pressure conditions required by emissions laws, this breakthrough is promising. Kansas State University scientists have added Euonymous Alatus (burning bush) genes to the Camelina Sativa plant to produce a thinner seed oil more suited for use in biofuels. Camelina grows easily, and since it isn't a food crop, concerns of genetic modifications are minimal. Testing of the oil in fuel could begin next year, after harvesting a large enough supply. Read more from Green Car Reports and from The Topeka Capital-Journal. The EPA's Mobile Vehicle Emissions Simulator (MOVES) could cause problems for higher ethanol blends. According to an editorial from Urban Air Initiative president David VanderGriend, MOVES is biased against ethanol blends, using test fuels that don't reflect the characteristics of real-world consumer fuels. "We must stop the MOVES model from being implemented, or all of the industry's other initiatives will be undermined," says VanderGriend. "States will have their hands tied and will simply not be allowed to approve higher blends." Read the column from Ethanol Producer Magazine. A Citroen C-Zero driver experienced unexpected fees when turning in the car at the end of its lease. The final bill included inspection and transportation fees under the "Damages" section of the report, totaling over GBP300 (about $470). The author has found no mention or documentation of such fees prior to collection, and is contesting the charges.
