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 CEO Mary Barra predicts mass electrification will take decades

General Motors is allocating a substantial amount of money to the development of electric technology, but Mary Barra, the firm's CEO, conceded that battery-powered cars won't fully replace their gasoline-burning counterparts for several decades. She stressed the shift is ongoing, but she hinted it will be slower than many assume. "We believe the transition will happen over time," affirmed Barra on "Leadership Live with David Rubenstein," a talk show aired by Bloomberg Television. She added that not every car will be electric in 2040. "It will happen in a little bit longer period, but it will happen," she told the host. She was presumably talking about the United States market; the situation is markedly different in Europe and in China, where strict government regulations (and even stricter ones on the horizon) are accelerating the shift towards electric cars. On the surface, it doesn't look like General Motors has much invested in electrification; the only battery-powered model it sells in America in 2020 is the Chevrolet Bolt (pictured), which undeniably remains a niche vehicle. Sales totaled 16,418 units in 2019, meaning the Corvette beat it by about 1,500 sales. In comparison, Cadillac sold 35,424 examples of the aging last-generation Escalade during the same time period. And yet, the company isn't giving up. It has numerous electric models in the pipeline including a slightly larger version of the aforementioned Bolt, the much-hyped GMC Hummer pickup, and an electric crossover assigned to the Cadillac brand. These models (and others) will use the Ultium battery technology that General Motors is currently developing. Its engineers are also working on a modular platform capable of underpinning a wide variety of cars. Bringing these innovations to the market is a Herculean task. EVs may not take over for decades, but Barra and her team must believe their 2% market share will increase significantly in the coming years if they're approving these programs. Autonomous technology is even costlier, more complicated, and more time-consuming to develop. Barra nonetheless expects to see the first General Motors-built driverless vehicles on the road by 2025. "I definitely think it will happen within the next five years. Our Cruise team is continuing to develop technology so it's safer than a human driver. I think you'll see it clearly within five years," she said on the same talk show. Her statement is vague but realistic.

Chip Foose is bringing life to a Cadillac sketch from 1935

General Motors, automotive home of Harley Earl, was a pioneer in the early days of car design. But for as many wild concept cars and even production cars as the company's studio created, there were still many that never got off the paper. Chip Foose is working to change the fate of one of those designs. According to Foose Design, Chip Foose's latest project is based on a sketch from 1935. Car dealer Wes Rydell and his wife Vivian commissioned a custom Cadillac coupe that was sketched out by GM designer Art Ross. It would take an existing Cadillac sedan, shorten it, lower it and give it a removable hardtop. The drawing is as far as the project got. Now Chip Foose is working on realizing the design in real life using a 1939 Cadillac Series 60 Sedan. He plans to follow the initial design brief, but with his own unique touches. He has also named the project "Madam X" in honor of what Harley Earl would call client projects. It is scheduled to be finished and ready for unveiling at the end of the summer. Foose is a well-known designer who has won some of America's most prestigious custom car awards such as the Ridler Award and designed vehicles for the TV show Overhaulin'. The final product should be quite a striking machine. You can see how it's coming along, as well as Foose's sketch of what the car will finally look like, in the gallery above.
