Chevy reveals new IndyCar aero package

The IndyCar Series is not one that demands its participating teams and automakers to design their own chassis as they do in Formula One, but for this season, the organizers have opened it up to allow for custom aero packages. What you're looking at here is the new look of the chassis to be fielded by teams running under Chevy power. Based on the Dallara DW12 chassis – introduced three years ago and named after the late Dan Wheldon – Chevy's new package is designed for road courses and short ovals, with the speedway configuration to be revealed later. The kit features new wings front and rear and more sculpted side pods. It's also got new wedges at the back to envelop the otherwise open wheels that are a hallmark of Indy racing, a more streamlined engine cover and bigger rear bumper pods. The new package will debut at the Grand Prix of St. Petersburg that will kick off this year's championship in Florida on March 29, followed by the road-course grands prix in Louisiana, Long Beach, Alabama and Indianapolis before the new package needs to be ready for the Indy 500 late in May. Half of the teams on the starting grid this season will be running under Chevy power and are expected to use this new aero kit, with the remaining Honda teams slated to run a different package of their own. Chevrolet Debuts All-New 2015 IndyCar Aero Package Chevy-developed bodywork delivers improved aerodynamics 2015-02-17 INDIANAPOLIS – Chevrolet-powered racecars in the 2015 Verizon IndyCar Series will feature Chevrolet-developed aero packages. Chevrolet introduced the road course/short oval body design today at the Indianapolis Motor Speedway. It is distinguished from the previous racecar with new front wing elements, sculpted side pods and a new rear wing. A speedway configuration for the aero kit, designed for high-speed ovals, will be introduced ahead of its competitive debut at Indianapolis in May. "This is an important milestone in Chevrolet's involvement in IndyCar racing," said Jim Campbell, General Motors U.S. vice president of Performance Vehicles and Motorsports. "We focused on developing an aerodynamic package that delivers an balanced combination of downforce and drag, along with integrated engine performance. It's a total performance package." The new Chevy road course aero configuration delivers greater aerodynamic performance than the previous design.

Weekly Recap: Ford guns for 2016 Le Mans glory with new GT

On the eve of the 24 Hours of Le Mans, Ford confirmed it will return to the French endurance race in 2016 and campaign the new GT racecar 50 years after three GT40s swept the podium at the Circuit de la Sarthe. The factory will back a two-team, four-car effort that will compete in the World Endurance Championship and the Tudor United SportsCar Championship running cars operated by Chip Ganassi Racing with Felix Sabates. The GT racecar will make its track debut in January at the Rolex 24 at Daytona, and the driver lineup will be announced later. "But rest assured, there's quite a line forming out the door," Ganassi said at the announcement. The GT is the modern successor to the iconic GT40, which won Le Mans four straight years from 1966-1969. The racecar is a rolling testbed of Ford's latest technologies, including a powerful twin-turbo EcoBoost V6. The car also makes extensive use of carbon-fiber pieces and advanced aerodynamics. Ford tapped Multimatic Motorsports of Canada and Roush Yates Engines to aid in the development of the GT racer. The road-going version, which was revealed in January at the Detroit Auto Show, is also set to launch next year. It caps Ford's growing performance lineup, and the company has ambitious plans to launch more than 12 new sporty models by 2020, including hot metal like the Focus RS, F-150 Raptor, and Shelby GT350R. The GT embodies Ford's best tech, but news of its return to Le Mans immediately conjured images of the company's fierce rivalry in the 1960s with Ferrari and intense competition with Porsche. "When the GT40 competed at Le Mans in the 1960s, Henry Ford II sought to prove Ford could beat endurance racing's most legendary manufacturers," Ford executive chairman Bill Ford said in a statement. "We are still extremely proud of having won this iconic race four times in a row, and that same spirit that drove the innovation behind the first Ford GT still drives us today." Ford is going back to Le Mans. Somewhere, Hank the Deuce must be smiling.

GM announces 3 new recalls affecting 1.7M vehicles in North America [w/video]

Still embroiled in the ongoing ignition switch recall, General Motors announced today three more discrete recalls, affecting a grand total of 1,546,900 vehicles in the US. The Detroit News reports that some 1.7 million vehicles are affected overall in North America. The first and largest of the trio of new recalls concerns some 1.18-million Buick Enclave and GMC Acadia crossovers from the 2008-2013 model years, Chevrolet Traverse from 2009-2013 (pictured above) and Saturn Outlook vehicles from 2008-2010. All of the crossover utilities may have an issue with the wiring harness for their seat-mounted side airbags. Apparently, the vehicles are equipped with a Service Air Bag warning light that, if ignored, "will eventually result in the non-deployment of the side impact restraints." Those restraints include the side airbags, a front-center airbag if the vehicle is so equipped and seatbelt pretensioners. Dealers of affected vehicles will be instructed to remove driver and passenger side airbag wiring harness connectors, and then "splice and solder the wires together." The second recall affects 303,000 Chevrolet Express (pictured right) and GMC Savana vans from model years 2009-2014, and with gross vehicle weights under 10,000 pounds. Said vehicles do not comply with a head impact requirement for unrestrained occupants, and will need a reworking of the instrument panel material to be sent back on the road. It doesn't sound as though there's a quick fix for this one, as the GM press release states: "Unsold vehicles have been placed on a stop delivery until development of the solution has been completed and parts are available." Finally, the third recall affects 63,900 Cadillac XTS luxury sedans from model years 2013 and 2014. A brake booster pump may be susceptible to corrosion by way of the relay, potentially causing and electrical short, overheating, melting of plastic components and even engine fires. GM says it is aware of two engine fires in unsold XTS models and two cases of melted parts. Repairs for the issues affecting the XTS have not not mentioned by GM in the release. The Detroit News is also reporting that along with news of the triple-recall, GM is taking a $300-million credit to help pay for the repair costs, and to deal with the ongoing costs associated with the ignition switch recall. In an attempt to explain just what GM has been doing in the face of these very serious issues, newly minted CEO Mary Barra has addressed the issues in a new video.
