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.

Cadillac vehicles to go electric by 2030, will get real names

DETROIT — The head of General Motors' Cadillac luxury brand said on Thursday that a majority, and possibly all, of the brand's models would be electric vehicles by 2030. Cadillac President Steve Carlisle also said Cadillac was on track for "low double-digit" sales growth in China in 2019, despite a drop in overall sales in the world's largest vehicle market. Retail Cadillac sales in the United States were on track this year for their first increase since 2013, Carlisle said. Cadillac has previously signaled a move toward electric models. Carlisle also confirmed Cadillac would offer a large electric sports-utility vehicle (SUV) similar to the Escalade and that it could continue to sell internal combustion models alongside electric vehicles, depending on consumer demand. GM expects to begin production of the large Cadillac electric SUV in late 2023 at its Detroit-Hamtramck plant as part of a planned $3 billion overhaul of the factory, sources have previously told Reuters. GM's luxury brand also plans to introduce a compact electric SUV in China in 2022, with a companion model slated to go into production in the United States in late 2023, suppliers said. Cadillac showed a concept for a midsized electric SUV earlier this year. The division will use names for its future electric models, moving away from number and letter names such as CT6 or XT5. "Escalade is an awesome name," Carlisle said. Cadillac will refresh its existing gasoline-powered models one more time over the next decade and then focus on the electric models, he said. "None of us knows how quickly the transition will take place," to a fully electric lineup, Carlisle said. A key challenge for electric vehicles is driving range and Carlisle said Cadillacs will need a range of 300 miles to be competitive. Eventually, he said, "you need to be at 400 miles" with charging times in minutes. Cadillac also will expand the number of models equipped with GM's Super Cruise semi-automated driving system, Carlisle said. GM executives have previously suggested that a more advanced version of Super Cruise was in the works. Earnings/Financials Green Cadillac Electric Luxury
