GM recalls 8,500 Chevrolet Malibu models for rear suspension glitch

According to a letter from General Motors to the National Highway Traffic Safety Administration, flaws in the build process of the 2013 Chevrolet Malibu have led to the recall of 8,519 cars. Units built between December 6, 2011 and January 15, 2013 may have been assembled with rear suspension cradles that had insufficient torque applied to certain bolts. That out-of-spec assembly could lead to issues ranging from slight noises to a loss of vehicle control.
The problem was first noticed in December of last year by a GM test fleet driver and eventually tracked back to the improperly torqued bolts on the suspension cradle assembled through July 2012 by a supplier located not too far from the Malibu's Detroit/Hamtramck Assembly Plant. Since an official NHTSA recall notice has not been issued yet, it isn't clear whether or not Detroit-built Malibus were the only ones affected (the 2013 Malibu is also built at GM's Fairfax Assembly Plant in Kansas City, Kansas). Dealers will fix the problem by inspecting vehicles for proper torque specs, retightening if not within specs and, in some cases, perform a rear-wheel alignment.

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.

2020 Ford Explorer vs 3-row crossover rivals: How they compare on paper

The 2020 Ford Explorer has finally landed, and if history serves as an indicator, it should be bigger than sliced bread. And people sure love themselves some sliced bread. This new Explorer may look familiar on the outside, but beneath the skin is a radically new rear-drive platform related to the Ford Mustang (as opposed to a front-drive platform related to the Ford Taurus and a Volvo from the 1990s). Turbocharged four- and six-cylinder engines now exclusively rest under its hood, which as you'll see below, both better anything its competitors offer. Ah, but if you're curious to know how the new 2020 Explorer compares to its various three-row family crossover rivals, take a look at the chart below where we stack it up against the 2019 Chevrolet Traverse, 2019 Honda Pilot, 2020 Hyundai Palisade, 2019 Subaru Ascent and 2019 Toyota Highlander. There are others of course (Mazda CX-9, Dodge Durango, GMC Acadia, VW Atlas), but we only had so much room on the chart, and these were the newest and/or most likely to be cross-shopped with the new Explorer. Engine specs and towing Although the Traverse's V6 just nips it on horsepower, the 2020 Explorer's base 2.3-liter "EcoBoost" turbocharged four-cylinder engine smokes it on torque. Therefore, "best-in-class" power seems like a fair claim from Ford. That there's also a 365-horsepower turbo V6 available, plus a hybrid and even-more powerful ST model on the way shows that Ford isn't kidding around under the hood. Curb weight also seems competitive for the segment. In terms of drivetrain, the Explorer is the only member of this particular group to come standard with rear-wheel drive (2.3-liter only). The Durango is the only other three-row, non-luxury crossover to do so. This is significant for two reasons: First, you could potentially do a power slide in an Explorer. Second, and more important, those in the Snowbelt will have to opt for all-wheel drive (it comes standard with the 3.0-liter). By contrast, a set of winter tires will probably do the job just fine if you want to save some money and gas by sticking with its rivals' standard front-wheel drive. Well, except for the Subaru Ascent — that's standard with AWD. In terms of towing, the Explorer takes the cake with as much as 5,300 pounds for the four-cylinder and 5,600 pounds for the V6. Everything else tops out at 5,000, though again, the Durango is capable of besting them all thanks to its Hemi V8 engine option.
