Chevy Silverado gets star-studded treatment at SEMA

Chevrolet has quite a presence ready for the 2015 SEMA Show, including custom takes on the Camaro and Spark. As one of the company's most popular models, the Silverado isn't left out of the fun, either, thanks to a trio of concepts to highlight what's possible for the aftermarket event. Camouflage is supposed to blend in, but the naval-inspired, Razzle Dazzle design on the Silverado Special Ops Concept should make the truck pop under the lights at the Las Vegas Convention Center. Based on a Silverado 1500 Z71, the pickup is conceived as a "rescue vehicle special-operations forces." To get behind enemy lines, it packs extra LED lighting, wheel flares for off-road tires, and a GearOn utility rack in the bed. Plus to help get away, Chevy Performance fits an air intake, exhaust kit, and concept six-piston brakes. The Silverado Realtree Bone Collector Concept (above) also wears camo for SEMA, but it's for enjoying the outdoors rather than getting out of battle. Camouflage company Realtree and The Bone Collector host Michael Waddell help with the design for this custom truck that features 22-inch black wheels, a front push bar, LED light bar, and assist steps all from Chevy Accessories. With leather upholstery, Apple CarPlay, and Android Auto inside, the drive to and from the woods should be comfortable, as well. The Silverado 3500HD Kid Rock Concept rounds out this trio and features patriotic styling from the eponymous rock star. "I wanted the design for the truck to be bold, but with features and elements that wouldn't be out of reach for working-class guys," he said about the design, and Kid Rock even visited the factory in Flint, MI, to meet members from UAW Local 598 for some inspiration. The result features a custom chrome grille with a Born Free logo and chrome exhaust stacks. For added excitement, two Gibbs Sports Quadskis are hooked up on the trailer behind it.

It is based on the Silverado 1500 Z71, which features a new front-end design and new technologies built into its strong, high-strength steel body structure and fully boxed frame, and draws its design inspiration from naval design aesthetics.

Chevrolet considering midsize crossover to slot between Traverse and Equinox

Crossovers are the new hotness, and automakers are looking to cash in by offering a size and shape for every customer. With Chevrolet's debut of the new 2018 Traverse in Detroit, which grew ever so slightly compared to the first-generation model, there is now a midsize-crossover-sized hole between the three-row Traverse and the compact Equinox. When asked about that obvious space, a Chevrolet spokesperson told us the company is looking into the possibility of expanding its crossover lineup. It should be a relatively simple thing to do, since all it would take is reskinning and rechristening the GMC Acadia with a bow tie, and we all know how much GM loves platform sharing. Although they're now different sizes, the new Acadia and Traverse still use the same platform; the Acadia is now on a short-wheelbase version of the C1XX while the Traverse uses long-wheelbase C1XX parts. A short-wheelbase Chevy built on the C1XX likely would be differentiated visually from both the Acadia and the larger Traverse. It may seem like flooding the lineup with more and more models would cannibalize sales of existing ones, but Chevrolet said it would rather have customers stay within the brand rather than going to another automaker. There have been whispers that some form of the Blazer name (possibly TrailBlazer) may make a return on a midsizer, but if it does don't expect an old-school body-on-frame SUV like the old one. In the end, if Chevy builds it, customers will come. Related Video:

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.

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.
