How GM's grueling 24-hour test gets the kinks out of its performance cars

One of the biggest challenges automakers face when designing a high-performance car is making sure that it is both fast and reliable. For General Motors, any car that might be taken to the track by its owner - like the Corvette, Camaro Z/28 (shown above) and the Cadillac CTS-V, for example - undergoes a rigorous and strenuous 24-hour test by engineers at the Milford Proving Grounds, as pointed out by Car and Driver.
We've posted on this topic in the past - on a video showing the Camaro ZL1 being brutalized, for instance - but this article gives a more in-depth look at what actually happens behind the scenes... including what that poor ZL1 went through. Though the test isn't for 24 hours straight, the cars are pushed as hard as possible by some of GM's best drivers with only the brakes and tires replaced frequently.
We don't want to ruin the fun for you, but it is an interesting article that tells just some of what GM does to develop its sports cars. Check out the full article over at Car and Driver for the rest of the story.

GM’s Charlie Wilson was right: Stronger regulations can help U.S. automakers

Charlie Wilson had been the president and CEO of General Motors before being nominated to become secretary of defense by Dwight Eisenhower. During his Senate confirmation hearings, he controversially said, "For years I thought what was good for our country was good for General Motors, and vice versa." And he was right. While car companies aren't necessarily the most progressive when it comes to things that might have the slightest possibility of political blowback, General Motors should be credited for doing something absolutely forthright in this regard with its announcement that it wants the federal U.S. government not to squash the California Air Resources Board's emissions requirements but to actually create a 50-state "National Zero Emissions Vehicle" program that, in the words of Mark Reuss, executive vice president and president, Global Product Group and Cadillac, "will drive the scale and infrastructure investments needed to allow the U.S. to lead the way to a zero emission future." Filing comments to the Safer Affordable Fuel-Efficient Vehicles Rule for Model Years 2021-2026 Passenger Cars and Light Trucks is one thing. But a graphic the company developed for this announcement — shown above — is something else entirely, something that is absolutely credible, creative and clever. There is a photo of a Chevrolet Bolt EV driving along a highway, which seems to be in Marin County (based on the blurred San Francisco skyline in the background). Text on the photo states: "It's Time for American Leadership in Zero Emissions Vehicles." It seems to say, in effect, "If we want to make America great again, then we're going to do it by leading in technology, not by retreating behind weakened regulations." General Motors understands that the auto market is globally competitive, and if U.S.-based companies are going to be in the game, then they'd better be able to out-innovate the companies based elsewhere, where emissions and economy standards are not being weakened.

Cadillac explains origins of Lyriq EV name

We feel for Cadillac, a brand we're inclined to dub the Alex Rodriguez of the automotive world — so much obvious talent, its gifts warped by repeated questionable moves and an inability to conclusively close the deal on The Big Stage. And as with Rodriguez, the expectations are so high at the same time the disappointment is so entrenched that Cadillac gets no benefits of any doubts, the commentariat ruthless with criticism for anything less than an out-of-the-park home run. This latest news, like the Newton-meter torque-based naming scheme initiated earlier this year, likely won't help. GM Authority asked Cadillac about the origin of the Lyriq name for the coming battery-electric crossover. Global head of brand strategy Phil Dauchy explained three threads that went into the new moniker. In no particular order, one thread is that "Cadillac," according to Dauchy, gets more mentions in song lyrics than any other brand, including non-automotive brands. The Music Lyrics Database, while not exhaustive, supports the case: Cadillac has 31 pages of lyric mentions among bands from Rancid to Weird Al Yankovic, beating every other brand we could think of. So ... lyrics into Lyriq. The second thread is rolled up with Cadillac's move to proper names instead of alphanumerics for the sedan and crossover lines, all of those names to end in "iq," as well as the push into electric vehicles. Dauchy told GMA the nomenclature overhaul and the two-letter suffix "[signal] that Cadillac is bringing a different type of vehicle to market, one that works in concert with man, nature, and machine." He's bullish on swaying the public with the product, adding, "When you see [the Cadillac Celestiq], its size, presence and scale all connote the emotion associated with the name." The final thread that went into the Lyriq name the alliteration of brand and model names. As GMA phrased it, perhaps unsettlingly, "With Cadillac and the model name both ending in an 'ick' sound, these names roll off the tongue quite well." This brings up a question raised in a number of comments about the Lyriq, which asks whether the last syllable is pronounced "ick" or "eek." Until now, I've pronounced the coming crossover with an "eek" at the end. "Lyr-eek" strikes me as more luxurious, and "Celest-eek" sounds better to me than "Celest-ick," that latter model being the flagship EV that follows the Lyriq. Of course, it also makes me wonder if I've been pronouncing "Cadillac" correctly.
