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.

Why Cadillac needs a real truck in its lineup

Premium brands such as BMW, Mercedes-Benz, Lexus, and Cadillac sell vehicles that cover the spectrum from car to crossover to SUV. But trucks? They remain the last frontier when it comes to luxury brands. These days Chevy, GMC, Ford, and Ram sell cheap, bare-bones work trucks alongside loaded models that top $75,000. There is a reverse elitism that comes with this sales tactic. A brand gets to reflect a rugged working class lifestyle with the emblem up front, while what's behind it costs as much as a small house in middle America. But Americans who spend big money on cars and SUVs have always gradually tailed towards luxury nameplates over time. Everyone knows what an Escalade is, and thanks in large part to that image the Escalade is now the best-selling fullsize luxury SUV in the USA. Cadillac's flagship model, along with its midsize luxury crossover, the SRX, routinely outsell the competition from Audi, Mercedes, and BMW, not to mention Ford's Lincoln brand and most of the Japanese rivals. With trucks already dominating overall sales and headed into the pricing stratosphere, I believe it's time for Cadillac to consider a fullsize truck. And no, not a lipstick version that merely takes a Chevrolet Silverado pickup and throws in a few leather seats and some slight interior touches. That experiment already failed both for Cadillac (the Escalade EXT) and for Ford's Lincoln brand (Blackwood, Mark LT). Cadillac is an American brand that currently focuses a ridiculous amount of energy and resources trying to compete with European car offerings. The brand needs to create the Cadillac of trucks. Head honcho Johan de Nysschen has been blunt in his desire to "restore Cadillac to the pinnacle of global premium brands, not in sales but in aspirational brand character." This sounds well and wonderful. But the present problem in achieving this goal is that, on a global basis, Cadillac is a failed brand. Look at Europe, where Cadillac has sold so poorly in recent years that former Soviet manufacturer Lada managed more new registrations in 2014 by a factor of more than four to one. Cadillac is an American brand that currently focuses a ridiculous amount of energy and resources trying to compete with European car offerings. After more than 20 years of Cadillac models selling themselves as import killers, the only one with sustained success has been the CTS, and even that has been a marketplace loser for the last several years. The CTS-V?

Cadillac Celestiq, Lyriq, Hummer, other future GM electric cars: Here's everything we saw at ‘EV Day’

WARREN, Mich. — Today, General Motors held an “EV Day” event at its Warren, Michigan, campus to present its new “Ultium” battery technology, modular electric vehicle architecture and soon-to-come electric vehicles. Unfortunately, we were forbidden from bringing cameras into the event, so while we canÂ’t show you what we saw, we can tell you more about it. While we saw the previously teased Cadillac EV (which we now know to be called the Lyriq) and the GMC Hummer pickup teased during the Super Bowl, there were a number of other future cars at the event, which GM President Mark Reuss assured us are all real vehicles in the works. The biggest surprise came at the end of the event, though, in the Cadillac Celestiq electric sedan, which Reuss described as a future flagship that would be hand-built “very locally.” It had been hiding under a dark sheet all morning, with the front and rear illuminated Cadillac emblems shining from underneath. When the wraps came off, we saw a long, white, four-seat fastback sedan. The 23-inch wheels were pushed out to the very corners of the car, giving it what appeared to be a very long wheelbase. The model on the stage had no side mirrors or visible door handles. The grille mirrored that of the Lyriq crossover next to it, with integrated lighting in lieu of the usual mesh or slats youÂ’d see in an internal combustion car. The entire roof, all the way until it tapered to the tail of the vehicle, was tinted glass. In back, vertical tail lighting ran down the C-pillar before turning rearward across the top of the trunk. Inside, everything below the beltline of the windows — essentially all but the headrests and top portion of the steering wheel, was hidden from view. Behind the Celestiq, a large digital display showed a rendering of its interior. The dash consists of a pillar-to-pillar curved LED display serving as both instrument panel and infotainment system. Protruding forward between the front seats was another touchscreen that appeared to house some more controls, with open area, probably for storage, below it. The rear seats had the same sort of touchscreen between them. Built into the back of the front seats were a pair of rear-seat entertainment screens, much like we saw in the Lyriq. The door panels blended wood, metal and animated lighting to give character and a sense of opulence. GM interior design manager Tristan Murphy was on hand to tell us a bit more about the Celestiq.
