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.

700 horsepower Porsche GT2 RS is the wildest 911 ever

The Porsche 911 comes in a variety of flavors, each filling a certain taste for a certain customer. Sitting atop the range is the new 911 GT2 RS. In previous generations, the GT2 had a bit of a reputation as a widowmaker, a 911 with massive power that could snap and bite with the slightest agitation. Porsche says the new model has been civilized, but with 700 horsepower going to the rear wheels, we're sure it's going to be as mad as ever. Power comes from a highly massaged version of the 3.8-liter flat-six from the 911 Turbo S. The rear-mounted engine makes an outrageous 700 horsepower and 553 lb-ft of torque. Like we previously reported, the new car will use water injection to help keep things cool. The only transmission is Porsche's PDK. While enthusiasts may lament the loss of the manual, the RS models have always been about performance above all else. Simply put, the PDK is the better performance option. All that power translates to a 0-60 mph time of 2.7 seconds and a top speed of 211 mph. The engine makes 80 more horsepower than the previous model. That makes it the most powerful road-going 911 ever built. In fact, the 887 horsepower 918 Spyder is the only road-going Porsche that makes more power. The fact that Porsche trusts all of that power to go to the rear is both thrilling and terrifying at the same time. In order to manage traction, the GT2 RS gets a number of upgrades. Rear-wheel steering has become commonplace in the 911 lineup, so it's no surprise to see it here. Sticky tires with 265/35 ZR 20 section rubber at the front and 325/30 ZR 21 section rubber at the rear keep things planted. That comically large rear wing adds downforce, adding to stability. The car gets standard carbon ceramic brakes. While some people prefer traditional rotors for the street, like the PDK, this is all about performance. A number of intakes and outlets complement the rear wing and maximize aerodynamic efficiency. It's a bit of a surprise that with all the focus on downforce, the GT2 RS still manages to top out at 211 mph. The hood, front wings, wheel housing vents, door mirrors, side air intakes, parts of the rear end, and a number of interior components are all made from carbon fiber. The roof has been made of magnesium. If you want to drop any pretense of civility and comfort in the pursuit of speed, Porsche is offering a Weissach package that shaves off another 40 pounds from the already impressive wet weight of 3,241.

Remember when Pontiac made a Trans Am Kammback grocery getter?

Despite muscle cars having strong reputations as some of the most impractical cars one can buy, they've occasionally had one of the most useful and practical features a car can sport: a hatchback. In the 1980s, General Motors' Chevrolet Camaro and Pontiac Firebird had one, and it added respectable utility to the sports cars. But the people at GM thought they could make the F-Body cars even more useful. So, after a few clay-model experiments, Pontiac built three examples of an extended-roof 1985 Pontiac Trans Am Kammback concept. Spotted by GM Authority, one of these Trans Am Kammbacks (although "shooting brake" seems like the more apt descriptor) is going on the block at the Mecum Kissimmee auction in early January 2019. Reportedly only three of these prototypes/experiments/test mules were built to driveable specs, and this example, VIN No. EX4796, has additional history that might make it the ultimate example. According to Mecum, the show car, which has made appearances at numerous auto shows, also spent some time at the race track — just not as a participant. It was used as a pace car for PPG and IMSA racing and temporarily had a light bar and "two-way communications equipment." Following its pace duty, and after GM stopped the project from going any further, it was put into Pontiac Engineering's private collection for 13 years. Famous Michigan car collector and Pontiac dealership owner John McMullen then bought the car. He eventually sent it to Pontiac specialist Scott Tiemann for a full restoration to the gorgeous condition it is in today. As seen in the photos, the Trans Am features white paint over a gray leather interior. It houses a 5.0-liter V8 under the hood and has a five-speed manual transmission. The wild concept is rare enough to be super cool, but we can't help but think of an infinitely more practical, more modern, more powerful, and arguably more interesting car we'd rather have. Manual Cadillac CTS-V Sport Wagon in Black Diamond anybody? Or, if you don't care about the extra doors, perhaps the Callaway's Corvette AeroWagen is more applicable. Either way, we're in full support of any shooting brakes we can find. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
