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 flagship, possible production Elimiraj, caught testing

One of the biggest debuts at the Monterey car week, both literally and figuratively, was the Cadillac Elmiraj Concept. The massive coupe made quite a splash with the show's well-heeled guests. Now, we have what might be the very first images of the Elmiraj, or whatever it may be called when it reaches production, out testing.
Don't let that modified Chevrolet Caprice body fool you, this car is about four to six inches longer than Chevy's US-spec cop car, from the A-pillar forward. According to our spy, with the Caprice at 203 inches and the concept at 205, adding a few extra inches here and there fits the bill for the four-door Elmiraj that was hinted at in Jay Leno's Garage.
There are a number of other classic mule signs on this car, including a cover over the fuel door and heavily modified front and rear fascias, each of which serves to hide some significant change from the standard Caprice. Using a Caprice for development also, hopefully, hints at something that big Cadillacs like the XTS have lacked - rear-wheel drive.

Texas sues GM, saying it tricked customers into sharing driving data sold to insurers

Texas filed a lawsuit Tuesday against GM over years of alleged abuse of customers' data and trust. New car owners were presented with a "confusing and highly misleading" process that was implied to be for their safety, but "was no more than a deceptively designed sales flow" that surrendered their data for GM to sell. The suit contends that at no point was selling driving data ever even suggested as a possibility, putting GM in violation of the state's consumer protection laws. Texas Attorney General Ken Paxton is seeking a jury trial and at least $10,000 per offense (every GM car sold in the state since 2015) and a hefty add-on of $250,000 in cases where the victim was over 65. Texas seems to be flying high after a recent $1.4 billion settlement from Meta over other privacy concerns. This may well be a way to solve any pending budgetary issues in the Lone Star State.
