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.

It's going to cost $12 billion to fix Cadillac

The Cadillac CT6's development predates Johan de Nysschen taking over at Cadillac, but the forthcoming flagship is the luxury brand's first major new product launch since the beginning of his tenure. The vehicle's debut also marks the beginning of a comprehensive $12 billion renewal plan bringing eight new vehicles in the next five years. Now, the former Audi and Infiniti exec is talking about joining Caddy and the company's future. "Cadillac will be a powerhouse global luxury brand that will command the respect of its peers," de Nysschen said about the forecast state of the company in 2020 to Bloomberg. He disclosed that three of those new vehicles under the five-year plan would be crossovers and reiterated that plug-in hybrids are on the way that would take advantage of the Chevrolet Volt's tech advances. De Nysschen also reminisced about joining Cadillac last year. He told Bloomberg that leaving Infiniti wasn't an easy decision, and there were apparently long conversations on the phone with General Motors President Dan Ammann discussing strategy for the luxury brand. De Nysschen was apparently clear that a greater investment and more autonomy from the corporate mother ship were vital. These days, the revitalization of Cadillac is just getting rolling. The company has a swanky New York office with a dedicated team to focus on the future. According to de Nysschen, the brand will grow its staff to around 150 people by the end of the year, compared to over 40 now. The marketing plan is to position the American luxury brand as a more distinctive product versus more common German rivals. It's going to be very interesting to see if this new Caddy can dare greatly enough to accomplish these lofty goals.

Cadillac planning its own engines, halo cars

Cadillac is in the midst of some big changes. It's got a new chief executive. It's taking some distance from parent company General Motors and moving to a new headquarters in New York. And it's instituting a new naming scheme that will allow not only for a more clear progression in its lineup, but also for more models. But that's not the end of the story. Not by a long shot.
Speaking with Automobile magazine, Cadillac's new president Johan de Nysschen revealed his intention to develop several new models and powertrains. For starters, he does not want Cadillac to continue borrowing engines from the GM parts bin, but intends to develop a new range of engines specifically for the luxury automaker. The program will likely start with smaller-capacity engines but eventually lead to new V8s as well, taking the place of the long-serving Northstar engine that finally ended its lifespan a few years ago after some two decades of production. Along with other technologies, de Nysschen envisions possibly sharing these powertrains with other GM divisions, but developing them first and foremost for Cadillac.
The bigger question, however, is where those engines would go, and de Nysschen had some thoughts to share on that front as well. For starters, the former Infiniti and Audi exec sees room for an even bigger sedan above the upcoming new CT6 that will cap the current range. Maybe even two of them. But that's not all. Johan wants to see Cadillac get (back) into the sports car game with a new halo model or two - something it hasn't really done since the Corvette-based XLR roadster. A pair of new crossovers are also said to be in the works, flanking the SRX on both sides with smaller and larger models.
