Best and Worst GM Cars

Oh yes, because we just love receiving angry letters from devoted Pontiac Grand Am enthusiasts, we have decided to go there. Based on a heated group Slack conversation, the topic came up about the best and worst GM cars. First of all time, and then those currently on sale, and then just mostly a rambling discussion of Oldsmobiles our parents and grandparents owned (or engineered). Eventually, three of us made the video above. Like it? Maybe we can make more. Many awesome GM cars are definitely going unmentioned here, so please let us know your bests and worsts in the comments below. Mostly, it's important to note that this post largely exists as a vehicle for delivering the above video that dives far deeper into GM's greatest hits and biggest flops, specifically those from the 1980s and 1990s. What you'll find below is a collection of our editors identifying a best current and best-of-all-time choice, plus a worst current and worst-of-all-time choice. Comprehensive it is not, but again, comments. -Senior Editor James Riswick Best Current GM Vehicle Chevrolet Corvette We were flying by the seats of our pants a bit in this first outing and my notes were similarly extemporaneous. When it came time to tie it all together on camera, I failed spectacularly. Thank the maker for text, because this gives me the opportunity to perhaps slightly better explain my convoluted reasoning. I chose the C8 Corvette because it's simply overwhelmingly good, and it's merely the baseline from which this generation of Corvette will be expanded.  While the Cadillac CT5-V Blackwing (more on that in a minute) is an amazing snapshot of GM's current performance standing and its little sibling so enraptured me that I went out and bought one, their existence is fleeting. Corvette will live on; forced-induction Cadillac sport sedans, not so much. So while all three are amazing machines when viewed in a vacuum, the Corvette stands above them as both a reflection of GM's current performance credentials and a signpost of what is to come. So, given the choice between the C8 and the 5V-Blackwing right now, I'd choose the C8. In 10 years, when the Blackwing is no longer in production and Corvette is in its 9th generation? Well, that might be a different story. Now, just pretend I said something even remotely that coherent when we get to the part of the video where I try to make an argument for the 5-V Blackwing as best GM car I've ever driven. Or just laugh at me while I ramble incoherently.

2015 Sierra All Terrain HD looks ready to hit heavy-duty trails

GMC is getting its heavy-duty trucks ready for the mud this summer with its All Terrain package for the Sierra 2500HD and 3500HD. Meant to blend style, tech and ruggedness, the pack includes a lot of extra chrome outside and an off-road package underneath.
The 2015 Sierra All Terrain HD trucks naturally come standard with four-wheel drive with an electronically controlled transfer case to handle things in the dirt. The Z71 off-road package is also standard, which includes Rancho twin-tube shocks, hill descent control and a skid plate. To add some style when off the beaten path, the pack includes chrome trim on the mirror caps, lower bumper and grille surround, plus LEDs around the headlights and 18-inch wheels (20-inchers are optional on the 2500HD). The 3500HD also gets chrome, adjustable outside camper mirrors. The interior receives a technology upgrade thanks to the standard rearview camera and IntelliLink infotainment that can act as a Wi-Fi hotspot through OnStar 4G LTE, read text messages and includes Siri Eyes Free for iPhone users.
The All Terrain package goes on sale on both trucks this summer and is offered on either the SLE or SLT trim levels in double cab and crew cab models. The standard engine is the 6.0-liter V8 with 360 horsepower and 380 pound-feet of torque, but the Duramax 6.6-liter, diesel V8 with 397 hp and 765 lb-ft is also available. The gas engine is mated to a Hydra-matic six-speed automatic, and the diesel uses an Allison six-speed automatic. Scroll down to read the full announcement about these heavy-duty off-roaders.

2023 J.D. Power Initial Quality Study shows there's less quality than last year

Vehicle inventory, vehicle pricing, and the supply chain are finally showing improvement. Vehicle quality, on the other hand, is still going the wrong way. That's the takeaway from the 2023 J.D. Power Initial Quality Study that found overall problems exceeded last year's record high. The study surveyed owners of 2022-model-year vehicles to assess the average rate of problems per 100 vehicles (PP100) during the first 90 days of ownership. The average figure for the 32 ranked manufacturers in 2020 was about 166 problems per 100 vehicles. In the 2021 IQS, that dropped to an average of 162. For 2022, the average jumped to 180 problems. For 2023, the PP100 is up to an industry average of 192 — an increase of 30 problems per 100 vehicles in just two years. Let's get to the good news first: Dodge reclaimed the crown of having the lowest number of problems per 100 vehicles at 140. Buick won last year with 139 PP100, falling to third this year. Dodge was the first American automaker to top the IQS in 2021. Its return as the least problematic gives parent company Stellantis three wins in four years after Ram was crowned in 2021. It also gives U.S. brands a four-peat after Buick topped the chart in 2022 by having owners report the fewest problems. This year's top 10 is Dodge, Ram, Alfa Romeo, Buick, Chevrolet, GMC, Porsche, Cadillac, Kia, and Lexus. Stellantis gathered a few feathers for its cap, in fact. Maserati showed the largest improvement year-on-year, followed by Alfa Romeo, and Alfa Romeo posted the lowest PP100 among the premium class, beating Porsche and Cadillac. Alfa Romeo has been vocal about working to improve quality, mentioning Lexus as a target. Last year the Japanese brand finished sixth, the Italians finished near the bottom, between Jaguar and Mitsubishi. This year Alfa jumped to third, Lexus dropped to tenth. Ram was the third-best on the list of improvers from 2022 to 2023.   The individual model with the lowest PP100 is the Nissan Maxima. Now for the troublesome bits. In the words of Frank Hanley, senior director of auto benchmarking at J.D. Power, "The industry is at a major crossroad and the path each manufacturer chooses is paramount for its future.
