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.

One of the world's largest muscle car museums is auctioning off its cars

Rick Treworgy's Muscle Car City is one of the biggest collections of high-performance American cars in the world. With over 200 cars of mostly GM makes, it's a mecca for fans of the golden age of Detroit iron. Unfortunately, the museum will be shutting its doors for good on Jan. 17 and auctioning off most of its assets with no reserve. The collection is, to put it bluntly, astounding. Advertised as a combined 65,000-plus horsepower, it occupies a 60,000-square-foot retail space in Punta Gorda, Fla., in a former Walmart store. It make sense when you learn that founder Rick Treworgy made his fortune in the commercial real estate business. As a hobby, he began to amass a truly jaw-dropping collection of muscle cars, filling out a collection that often has every year of a particular model represented, or a grouping of the rarest and highest-performance option packages of that year or model. Often, Treworgy bought placeholders while scouring the country for even rarer versions. It helps that Muscle Car City also houses a showroom where unwanted cars are sold, as well as its own speed shop that stocks plenty of parts. There's even a '50s-style diner called Stingray's Bar and Grill. According to a 2014 episode of Car Crazy, Treworgy has 80 Corvettes alone, more than the actual Corvette Museum. Among them are 20 models from 1967, one of Treworgy's favorites. The rest span the decades from 1954 (he once had a '53 but sold it) to a recently acquired 2020 C8, which, according to The Drive, has only 300 miles on the odometer. You like Impalas? There are models of every year from 1958 to 1969. El Caminos? He's got 'em from 1964 to 1972. Novas? Every year from 1963 to 1970 is represented. Most are the more desirable examples of each breed, with four-speed transmissions, the biggest blocks, and unicorn option packages like a factory 1965 Z16 SS396 Chevelle, one of 200 that were ordered off-menu at Chevy dealerships. And don't even get us started on the Camaros, which include not one, but two COPO 1969s. Treworgy even owns the only known surviving example of a 1936 Chevrolet Phaeton, of which only seven were built. On top of it all, many of these cars are concours quality and have won awards at prestigious car shows. While it's sad to see a collection like this broken up, Treworgy told The Drive that he'd been planning to retire next year anyway. However, the COVID-19 pandemic sped up those plans, greatly reducing the number of visitors to his museum.

Cadillac boss: Don't ask why we have so many sedans

Ugh, crossovers. Car-based, high-riding station wagons, for some reason, sell in absurd numbers and make automakers lots and lots of money. That's why automakers with a strong lineup of CUVs are running strong, while sedan-heavy brands are struggling. Cadillac is all too aware of this fact. While the company is preparing to launch the new CT6 luxury sedan, it's also realizing four sedans, a coupe, a crossover, and a $73,000, old-school, body-on-frame SUV does not a healthy lineup make. Worse, though, as Cadillac President Johan de Nysschen rued during the LA Auto Show, is that the new CT6 is joining a segment already oversaturated. While it's a big, expensive vehicle, it's not much bigger or more expensive than the CTS and XTS sedans. "Please don't ask me why we have three cars in the same segment," de Nysschen said, stopping midway through an interview with Automotive News on the CT6's market placement to make the crack. "That's a whole different subject." As for those CUVs, the new XT5 debuted in LA, and it will eventually be joined by another much-needed CUV in 2018, AN reports. Related Video:
