2014 Chevrolet Impala [w/video]

Can A Fleet Queen Become a Fullsize King?
On paper, the Chevrolet Impala is a pretty strong seller, posting annual sales that have hovered right around 170,000 units for the last two years, but it only takes one trip to practically any rental car agency to discover where the majority of those sales have come from. In fact, General Motors told Autoblog that a full 70 percent of Impala sales last year went to fleet companies for things like rental cars and government vehicles. Logic tells us that this is neither good for resale values nor name equity, so Chevrolet is getting ready to roll out an all-new Impala with improved comfort, styling and technology, hoping to turn the tables on its retail-to-fleet ratio.
Chevrolet's sedans have come on quite strong in the last few months with the introduction of the Cruze diesel and the SS sedan, but while these will likely be low-volume sellers, there's more pressure for the new Impala to perform well as GM looks to slash fleet sales and compete with the wide variety of full-size sub-luxury sedans. Riding on a platform shared with the Buick LaCrosse and Cadillac XTS, the 2014 Impala will compete against the Hyundai Azera, Ford Taurus and Toyota Avalon on the more traditional side, while also looking to take a bite out of somewhat sportier models like the Chrysler 300/Dodge Charger twins and the Nissan Maxima. We headed to sunny San Diego to see if this totally new Impala can stand on its own without the assistance of fleet companies and rental agencies. [w/video

Ringbrothers drops more hints about its wild SEMA creations

Ringbrothers isn't finished teasing its SEMA creations. First we got a sliver of rear quarter on a 1969 Chevrolet Camaro that revealed a bundle of carbon fiber and SEMA-obligatory deep-dish wheels. The Wisconsin tuner's now announced its litter of cars headed to the show and a few specs, along with two shadowy drawings. The Camaro, christened with the name Valkyrja and a two-tone paint job, gets stretched in two directions with severe fender flares to widen the body and an extended wheelbase. We're not sure what's happening with the Camaro's snout in the drawing, but under that bulging hood we'll find a 416-cubic-inch LS V8 from Wegner Motorsports. Wegner built the 416-cu-in supercharged LS3 V8 that powered Ringbrothers' 1,000-hp G-Code Camaro in 2016.  The second member of the gang is a 1969 Ford Mustang Mach 1 dubbed Unkl. The exterior begs for attention with a deep blue sea paint job, deep front chin spoiler, bulging hood, yellow brake calipers, and what looks like a racing number inside a roundel on the doors. Unkl gets its motivation from a 520-cu-in Boss V8 built by Kaase Racing Engines, rumored to throw about 800 hp.    Finally, Ringbrothers is bringing its Cadillac Madam V for another Las Vegas go-round after giving the custom coupe some updates. The Madam V is a 1948 Cadillac Series 62 fastback coupe body placed atop an ATS-V chassis, first shown in 2016. The firm didn't elaborate on the changes, so all we can expect for now are the coupe's postwar good looks mixed with new-millennium engineering, and a 3.6-liter twin-turbo V6 with 464 hp under that exceptionally long hood.    For any in attendance at the show, the Valkyrja Camaro debuts at the BASF booth on Tuesday, Nov. 5, 2019 at 9:30 a.m., the Unkl Mustang gets revealed a couple hours later at the Flowmaster/Holley booth, and the Madam V Cadillac will be on display throughout the show at the Ringbrothers booth.

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.
