Corvette Z06 and Viper TA square off at the strip

There are many long-standing grudge matches among automobiles: 911 vs GT-R, Mustang vs Camaro, Ferrari vs Lamborghini... but as far as high-end American metal goes, it doesn't get much more legendary than Viper vs 'Vette. So after Chevy released the new Corvette Z06, we knew it was only a matter of time before it would have to square off against the Viper TA. And what better place to pit these two parallel pillars of American performance than on the drag strip? Fortunately that's just what we have here. In one corner, the 2014 Dodge Viper TA, with its 8.4-liter V10 pumping out 640 horsepower and 600 pound-feet of torque. In the other, the 2015 Chevrolet Corvette Z06, the supercharger on its 6.2-liter V8 more than making up for the discrepancy in displacement and cylinder count to produce 650 hp and just as much torque. But numbers don't tell the whole story, so watch the video clip to see which reaches the end of the quarter-mile first.

Buick Encore, Chevy Trax reportedly dead after 2022

The Buick Encore will not get an encore, and the Chevrolet Trax is dead in its tracks. Separate unverified reports say the two crossovers, which are essentially identical underneath the sheetmetal, will retire at the end of the 2022 model year without being directly replaced. Citing anonymous sources, enthusiast website GM Authority wrote that production of the Encore and the Trax is scheduled to end in the third quarter of 2022. Both models are manufactured in Bupyeong-gu, South Korea, and General Motors will reportedly use the extra production capacity to build more examples of the Trailblazer, which outsold the Encore and the Trax combined by a significant margin in 2021. General Motors hasn't commented on the report, but we wouldn't be surprised if the end is indeed near for the Encore and the Trax. Buick released the Encore for the 2013 model year, and Chevrolet launched the Trax for 2015, but the model made its debut as the Opel Mokka in 2012. It's at the end of its life cycle, and sales figures reflect this: 20,072 units of the Encore were sold in America in 2021, a drop of 52% compared to 2020, while 42,590 examples of the Trax found a home, a 60% decline. It's further proof that Americans don't like small cars. Viewed in that light, the decision not to replace either crossover makes perfect sense. If the report is accurate, the Encore GX (which is not related to the Encore in any way) will enter the 2023 model year as Buick's entry-level model. The situation is a little more complicated at Chevrolet: The pocket-sized Spark is on its way out in 2022 as well, meaning that the Trailblazer will become the entry point into the range. It's a different story in Europe: Opel, which is now part of the Stellantis group, released the second-generation Mokka in June 2020.

Why an independent rear suspension for GM's new, full-sized SUVs wasn't easy

A Motor Trend report last month laid out how Cadillac's 4.2-lier twin-turbo Blackwing V8 could be an orphan due to cost concerns in the GM empire. Last-minute chassis changes to Cadillac's new sedans and XT6 crossover led to engine bays that couldn't fit the Blackwing. On the SUV side, according to the report, the new independent rear suspension for big people haulers cost so much to implement that GM ruled out reworking the Escalade to accept the Blackwing. At least one commenter rightly asked how could a suspension swallow that much money. A new piece in Motor Trend has the answer. The excellent Alissa Priddle spoke to Tim Herrick, GM's executive chief engineer for full-size trucks, about why the clean-sheet IRS cost "multimillions of dollars."  First, GM would need to build a new body shop at the Arlington, Texas plant that assembles the automaker's big SUVs to stamp the numerous wholly new parts and panels accommodating an IRS. Then GM would need to design and pay for a new assembly process. On top of those up-front costs, there was the incremental cost of the four-link IRS components being more expensive than those in the trucks' former leaf-sprung solid axles. Herrick endured so many rejections for so long that he remembers the date and time when he got approval for the new unit. He said it came down to a meeting where he told a higher-up, "I'll make you a deal: If we get to the reveal, or if we launch this and you think this was a dumb idea, I'll hand you my badge and let you walk me out." Head to Motor Trend to read the full story. Based on Herrick being on stage to help present the new SUVs to the press, and on our First Ride in the new Chevrolet Tahoe and Suburban at GM's Milford Proving Grounds, it appears this will have a happy ending for all involved. Furthermore, since Herrick worked on the T1 platform that supports the big SUVs as well as the light- and heavy-duty pickups, he understood the demands on the commercial side, too. That could be why when Roadshow asked Tim Asoklis, chief engineer of the Tahoe and Suburban, if the new IRS could endure life in the Chevrolet Silverado and GMC Sierra, Asoklis answered, "Oh, absolutely."
