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 V-Performance Academy joins free driving school party

Just in case you needed another reason to want one of Cadillac's hottest performers, starting with the 2017 Cadillac CTS-V and ATS-V, the first owner of each vehicle can score a free two-day course at Spring Mountain Motor Resort with the V-Performance Academy. According to Spring Mountain's website, the V-Performance Academy "is designed for drivers of all experience levels and includes dynamic car control exercises, visual skill development, and proper cornering techniques," with "brief" classroom sessions sprinkled in. Driving programs like the V-Performance Academy are all the rage right now. In the last few weeks alone, both Fiat and Ford announced free one-day academies baked right into the price of cars like the 124 Abarth and Focus RS. As with the Ford and Fiat courses, Cadillac is providing the learner cars. But where those other courses call on vehicle owners to shell out for airfare, food, and in Fiat's case, lodging, Cadillac covers tuition – a $2,420 expense for non-owners – along with two nights in one of Spring Mountain's "luxury condominiums" and breakfast and lunch during both driving days. Students are still on the hook for airfare, although Caddy will shuttled attendees from Las Vegas McCarren to the track/resort, some 55 miles away. If you can't shell out for the flight to Las Vegas, a new CTS-V or ATS-V, or simply can't spare two days for a driving school, Cadillac is ramping up for another year of its one-day, traveling V-Performance Lab, which will run at Lime Rock Park in Connecticut and at Circuit of the Americas in Texas.

Cadillac CT6 to get twin-turbo V8

Say what you will about his decisions at Infiniti and now Cadillac, but Cadillac CEO Johan de Nysschen knows how to deliver a compelling interview. During an online Q&A session with Jalopnik readers, de Nysschen offered substantial hints at what's coming for the brand. By dropping coordinates on the brand's star chart, in reading the entire thing and connecting the dots you can see a Cadillac that is much grander than the one we know now. The CT6 that got revealed during the Oscars telecast? Answering the question of whether it would have the performance to compete with a Mercedes S550 or BMW 750, de Nysschen said the big sedan's "lightweight body structure allows us to achieve formidable performance even with a twin-turbo V6. Imagine how this car would perform with a twin-turbo V8." In clarifying a subsequent question that also dealt with how the CT6 would compare to German rivals, he wrote that the CT6 would have "a very wide mix of engines, starting with a two-liter turbo, up to, eventually, a high-performance advanced V8 turbo." Patience and the future and the word "eventually" were heavy themes. The brand will embrace diesel engines as well, de Nysschen writing, "We will have four-cylinder and six-cylinder diesel engines, but not before 2019." As to the return of something like the XLR, which was Corvette muscle underneath a Cadillac body, he wrote, "I think in the fullness of time, we will get around to developing a high-performance, very-emotive sports car as a halo for the Cadillac brand. But we have so many projects to occupy us through 2020 that this will have to wait a little while." And on the design language across model lines, which enthusiast Cassandras have warned is too similar (as if that hasn't worked out for the Germans), he wrote that it is "undergoing gradual evolution and you will notice stunning new designs in future models, which remain unmistakably Cadillac and reflect our DNA but which take our sophisticated Art and Science design to a new level." But of course he would say that, which is what brings us back to patience and the future and eventually, when we'll see what this all really means. It all reads well enough, and we'd love to see it happen. One thing we won't see are the ducks that once adorned the Cadillac crest; when a reader asked if he could have them back, de Nysschen said, "No, you can't have them back. I play with them each night in my bath." Head over to Jalopnik for the full read. It's worth it.
