Honda, Chevy reveal low-drag speedway aero for Indy 500

As the two automakers currently participating in the IndyCar Series, both Chevy and Honda were invited this year not only to provide engines to the teams on the starting grid, but to develop their own aerodynamics packages as well. Both revealed their designs for the road-course races a few months ago, but with the Indy 500 approaching at break-neck speed, they've now unleashed their aero approaches for speedways. Both are based on the Dallara DW12 chassis introduced to the series a couple of years ago, but sacrifice some of their downforce at the altar of speed. And you can tell as much from looking at them: both Honda (above) and Chevy (below) have streamlined their designs, with single-plane front wings, lower-profile rear wings and fewer winglets on the body and around the wheels in between. The idea is to allow the cars to reach higher top speeds with less drag, while offering the necessary amount of downforce for the banked turns. With the four opening road-course rounds complete, teams using either automaker's equipment will keep the existing aero kits on their cars for the Grand Prix of Indianapolis on the infield course next week, then switch to the speedway package for the Indianapolis 500 later this month. Then it'll be back and forth for the rest of the season as the circus switches between road courses and speedways. Honda Unveils 2015 IndyCar Super Speedway Aero Kit Apr 30, 2015 - SPEEDWAY, Indiana - To be used at the Indianapolis 500 - Manufacturer seeking 11th Indianapolis 500 victory since 2004 - First public running to take place Sunday at Indianapolis Honda today debuted the "Super Speedway" aero kit of aerodynamic upgrades and components its teams will use at this year's 99th running of the Indianapolis 500. The Honda Super Speedway Aero Kit, produced by Honda Performance Development, Honda's racing arm in North America, includes a variety of individual aerodynamic components fitted to the existing Honda-powered Dallara Indy car chassis. All are intended to give Honda's six Indy car teams – encompassing a potential 17 '500' entrants - the ability to maximize performance at the 2.5-mile Indianapolis Motor Speedway oval and other large ovals ( over one mile in length) on the 2015 Verizon IndyCar Series schedule. "We're excited to unveil our Super Speedway aero kit, the newest element in this era of enhanced manufacturer competition in the Verizon IndyCar Series," said Art St. Cyr, president of HPD.

GM struggles to sell small cars, plans to lay off 2,084 employees at two plants

Due to low demand for some of its vehicles, General Motors plans to cut 2,084 jobs at its assembly plants in Lordstown, OH and Lansing, MI. At the same time, the automaker also announced plans to invest approximately $900 million in three of its facilities – the Toledo Transmission Operations in Ohio, Bedford Casting Operations in Indiana, and Lansing Grand River in Michigan - for future products. GM will discontinue the third shift at both the Lansing Grand River plant and the Lordstown, OH plant. The Cadillac ATS, Cadillac CTS, and Chevrolet Camaro are made at the automaker's plant in Michigan, which currently has 2,700 employees. The move to eliminate the third shift affects 810 hourly workers, as well as 29 salaried employees, starting on January 16th. The plant in Lordstown, OH currently has 4,500 employees and makes the Chevrolet Cruze sedan. The plan to discontinue the third shift will affect 43 salaried workers and 1,202 hourly employees and will start on January 23rd. As Fortune points out, sales of the Cruze are down 20 percent through October, while sales of the Cadillac ATS and CTS were down 17 percent through the same period of time. In addition to cutting the third shift at both assembly plants, the automaker plans to invest a total of $900 million between three of its facilities for unnamed future products. GM's Toledo Transmission Operations will receive $667.6 million, the Lansing Grand River Assembly plant will receive $211 million, and the automaker's Bedford Casting Operations will get $37 million. Last year, GM cut roughly 500 jobs from its Orion Township factory due to slow sales of the Chevrolet Sonic and Buick Verano, with surging crossover and SUV sales as the most likely culprit. With GM posting much healthier sales figures for the Chevrolet Equinox and Cadillac XT5 compared to the ATS, CTS, and Cruze, it looks like compact SUVs are to blame for this year's layoffs as well.

GM recalls 330,000 fullsize trucks for airbag replacement

General Motors has announced a recall of 330,198 fullsize pickups in the US in the aftermath of the announcement made on May 19 that doubled the number of vehicles being called in to replace Takata's defective airbag inflators. That announcement expanded the nationwide recall to an estimated 33.8 million vehicles in the US. Heavy Duty versions of the 2007 and 2008 Chevrolet Silverado and GMC Sierra are included in GM's move, for the purpose of replacing the passenger airbag inflators. The announcement made by the National Highway Traffic Safety Association cited long-term exposure to moisture as a possible cause of the inflator issues. GM says it isn't aware of any problems with the recalled pickups due to moisture, nor has it had any reports of crashes, injuries, or fatalities, and has not received any complaints. GM will notify owners, who can then take their trucks to the dealers to have them repaired free of charge. You'll find a statement from GM and the recall notice from NHTSA below.
