Chevy's low-cost pedestrian avoidance to debut on 2016 Malibu

The mainstreaming of safety technologies that began on luxury vehicles will get a big boost from General Motors later this year. The General says it plans to offer 22 driver assistance systems across its product portfolio of 2016 models, starting with the redesigned Chevrolet Malibu - the one that we know will keep tabs on teenagers for the benefit of parents. Pedestrian avoidance will be another of its available options. Instead of kitting the sedan out with numerous and expensive radar arrays, the GM system uses the camera mounted next to the rearview mirror that is already used for the lane-keeping function. New software lets it detect pedestrians, and when it detects a potential collision with one, it can alert the driver and brake autonomously if the driver doesn't react. Eventually, engineers want to give it the ability to do the same with cyclists. Because it uses existing hardware updated with new code, GM says the application costs "a few hundred dollars." GM demonstrated the Front Pedestrian Braking preventing a crash with a dummy pedestrian at speeds up to 15 miles per hour. Automotive News reports that it will reduce the severity of impact up to 40 miles per hour, but "may not be of much use in collisions at higher speeds." That feature will also join the options list of the Cadillac CT6. The press release below has more on GM's driver tech soon on the way.

Safety engineers will develop and test these and other safety technologies for products around the world at GM's new, 52-acre Active Safety Test Area at its Milford Proving Ground near Detroit. The $14 million facility officially opened Friday. "Our comprehensive safety strategy of helping customers before, during and after a crash continues," said Jeff Boyer, vice president of GM Global Vehicle Safety.

Next-gen Chevy Silverado and GMC Sierra may use carbon fiber

It's been generally accepted that the next generation of full-size GM trucks will use some sort of strong, lightweight material for the beds while retaining steel for the cab. While aluminum seems like the most obvious choice, according to Automotive News, the Chevy Silverado and GMC Sierra will incorporate both aluminum and carbon fiber in their beds. The publication cites sources from within GM, though it seems the introduction of this comparatively exotic material mix is still a few years off. While carbon fiber is both stronger and lighter than steel and aluminum, it takes significantly more time and money to produce, essentially relegating the material to small-volume cars. The main benefit for trucks is the resulting reduction in weight to improve fuel economy without sacrificing the tough, rugged capabilities truck buyers expect. The Ford F-150 made the switch to aluminum for the 2015 model year and it's proved highly successful. It seemed like it was only a matter of time before the competition followed suit. Automotive News says that the next-gen trucks will launch with aluminum beds and that it will take a couple of years before we'll see any carbon fiber incorporated into the design. Even then, only look for the composite material on higher-trim models, with a trickle down to lower-spec trucks possible further in the future. In 2011, GM announced it was working with Japan-based Teijin Limited on a carbon fiber reinforced thermoplastic. There's a good chance that material's introduction will be on trucks.

Recharge Wrap-up: EV torque secrets, UC Davis maps future of biofuels

A UC Davis white paper maps out "Three Routes Forward for Biofuels," balancing investment risk with carbon benefits. The first option is "incremental," in which we tinker with the existing biofuel manufacturing infrastructure for small improvements over time. The "transitional" plan suggests integrating cellulosic production and other innovations with existing operations. The third route, called "leapfrogging," would mean building refineries based on new technology such as cellulosic and algae-based biofuels. The paper suggests ways the US could use these three routes together in different areas, and predicts the payoffs in terms of carbon emissions could be significant if the right people are willing to risk the capital. After all, financial advisers are always telling investors to diversify their portfolios to manage risk and rewards in the same way.

The seventh round of the inaugural all-electric race season, which was moved from Los Angeles to the streets of Long Beach, will offer fans free grandstand and general admission. The race, which takes place on April 5, 2015, will use a 1.6-mile portion of IndyCar's Grand Prix of Long Beach. Read more at LA Times. Polaris is now offering its 2015 GEM electric vehicles, including the new street-legal eM1400 LSV. The passenger and utility vehicles come in two- to six-passenger configurations, many of which are street legal on roads with posted speed limits of up to 35 miles per hour. The eM1400 LSV utility vehicle seats two, offers 1,250 pounds of payload, 1,250 pounds of towing capacity, a top speed of 25 mph and a range of up to 45 miles. Its on-board charger plugs into any standard 110-volt outlet. Read more at Hybrid Cars and check out all the different configurations yourself at the Polaris website. In EVs, more torque does not always equal faster. Green Car Reports found this out when driving the Fiat 500e (with 147 pound-feet) against the similarly weighted Chevrolet Spark EV (with 400 pound-feet). The secret is, at least in part, in the gearing. The Fiat has a 9.6:1 reduction gear, making it quicker at lower speeds despite having far less available torque, while the Chevy uses a 3:1 ratio. The trade-off though, is in top speed. Furthermore, Chevy electronically limits the torque delivery at low speeds, as 400 pound-feet is a lot of launch for the little Spark EV to handle.
