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.

First 2015 Chevy Corvette Z06 engine blows up at just 891 miles

You've waited and watched and waited some more for the arrival of your 650-horsepower, $78,000 Chevrolet Corvette Z06. Finally, that joyous day arrives and you eagerly, but gingerly, begin to break-in the 6.2-liter supercharged V8 monster under your hood. Then 900-odd miles after delivery, your excitement grinds, quite literally, to a halt. That's what the owner of one 2015 Z06 claimed happened to him when a simple break-in drive resulted in a lunched engine. The owner, known as Lawdogg149 on Corvette Forum, says he was out breaking-in his car ahead of a January track event when it happened. "While making a pull from 35 miles per hour, I accelerated and shifted short of redline, and boom - the car began knocking. I pulled over and popped the hood. I could hear a loud knock coming from the No. 6 cylinder area along with a serious, grinding, metal-on-metal sound coming from the supercharger area," Lawdogg wrote. A subsequent trip to the dealer confirmed his concerns, with the service facility telling Lawdogg that the No. 6 valvetrain had failed. The dealer couldn't research the issue further, though, as General Motors requested the engine be returned for a more thorough evaluation. The good news for the Z06's unlucky owner, at least, is that GM will be covering the engine replacement under warranty, an expense that Corvette Forum estimates is a nearly $24,000 procedure. At this point, the two leading theories behind the engine's detonation involve a manufacturing defect – which could be why GM is so keen to tear the blown powerplant down – or a mistake on the part of Lawdogg. As Motor Authority points out, such an error could be something as simple as the Z06's owner accidentally shifting to first rather than third during his 35-mph pull. If, however, there's a deeper manufacturing problem with the Z06's engine, this might not be the only case we end up hearing about.

Chevy, Lincoln dealers say they still want sedans

Detroit automakers have famously turned their backs on sedans as they make the strategic bet to double down on money-making trucks and SUVs, but dealers for at least two American brands are giving the companies contrary signals. In separate recent interviews with leading national dealer councils for Chevrolet and Lincoln, Automotive News reports that both brands’ dealers still see a need for cars. The publication published a Q&A interview with Mike Bowsher, chairman of the Chevrolet National Dealer Council, who said Chevy dealers managed to hold onto market share last year despite the phase-out of the Cruze compact sedan and hatchback, thanks to products like the Spark and Sonic subcompacts and the Trax and Equinox crossovers. But, he acknowledged, “We do feel like we could use a car, especially in the low-MSRP range.” The comments follow similar recent comments from Tom Lynch, who chairs the Lincoln National Dealer Council. He told AN, “If weÂ’re not in segments where there is still a good amount of business, I think the company and the dealers lose out.” The Cruze was one of the victims of GMÂ’s November 2018 announcement of plant closures, with production having ceased with the closure of GMÂ’s Lordstown, Ohio assembly plant last year. GM sold 47,975 Cruzes in 2019 but a healthy 142,617 in 2018. At Lincoln, Lynch said the council has been telling the company it needs to stick with the sedan segment, despite plans to kill the MKZ sedan in the coming months and unconfirmed reports that the Continental isnÂ’t long for this world, either, despite the buzz of the suicide-door Coach Door Edition, shown in the photo above. Lincoln sold 17,725 MKZs and 6,586 Continental sedans in 2019, down a combined 15%, but still good for almost 22% of overall Lincoln sales. It's worth noting that Lincoln competes in a luxury segment that still expresses allegiance to four- and two-door cars. Even Cadillac, its cross-town rival, is staying active with the upcoming CT5 and CT4 sedans. Lynch pointed to Tesla as evidence that strong sedan products can resonate with consumers, though he conceded that “What that looks like for Lincoln going forward, IÂ’m not sure of.” For now, anyway, Chevy still offers the Sonic and Spark subcompacts, the latter of which saw sales climb 32.5% in 2019 to 31,281 (Sonic sales fell nearly as steeply).
