GM files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.

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.

2019 Toyota Avalon vs. full-size sedans: How they compare on paper

Full-size sedans aren't exactly in great demand at the moment, and at least one of the vehicles in this comparison has been rumored to be on the endangered species list. Yet, we've just had our first drive in the 2019 Toyota Avalon, and if anything has a chance of rejuvenating the segment a bit, it's an all-new version of what has long been the segment's benchmark. To see how the new Avalon compares, we've put together the below spreadsheet featuring the Avalon's primary apples-to-apples rivals, the Buick LaCrosse and Chevy Impala. We also included the Nissan Maxima, which is comparable in price, sales and non-luxury badge, and which offers the sort of increased driver engagement promised by the new Avalon XSE and Touring trim levels. We also included the outgoing Avalon for reference as well as that car's luxury cousin, the Lexus ES, which can definitely be cross-shopped with the luxuriously trimmed Avalon Limited. You can use our Compare Cars tool to create your own comparison, such as one featuring the rear-wheel-drive Chrysler 300, Dodge Charger or even Kia Stinger. Alright, enough chit chat. On to the spreadsheet. Performance and fuel economy The GM sedans may come standard with four cylinders, including a mild hybrid system in the LaCrosse, but puh-lease. The V6 is the name of the game in this segment, with outputs now surpassing the 300-horsepower mark. The LaCrosse is the horsepower and torque champ, though it also weighs a bit more than the new 2019 Avalon, so acceleration is likely to be comparable. The Impala weighs a lot more and has only a six-speed automatic, so despite having a wee bit more power, one should expect it to be pokier (not a good sign for a car rumored to be on the chopping block). One would expect the Maxima's 300 hp and lowest curb weight to result in the quickest acceleration, but then it's also strapped to a CVT, which despite being better than ever, is still a CVT. Things get worse for Chevy when you consider the Impala's base four-cylinder gets the same 25 mpg combined as the Avalon's V6 — once again a segment best. Now, should you really prioritize fuel economy, the 2019 Toyota Avalon Hybrid really stands out with a 43 mpg rating (or 44 with the base XLE trim) that bests the outgoing Avalon Hybrid. Honestly, after driving this new Hybrid, it actually seems like it would be the best bet for most buyers. There's sufficient power, and it only costs $1,000 more than the comparable V6 version.
