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 To Offer Car That Will Almost Drive Itself

Cars that can talk to each other and almost drive themselves at freeway speeds are just two years away from the showroom, according to General Motors executives. The company announced Sunday that the semi-autonomous system for freeways will be an option on an unidentified new 2017 Cadillac that goes on sale in the summer of 2016. In addition, another 2017 Cadillac, the CTS, will be equipped with radio transmitters and receivers that will let it communicate with other cars, sharing data such as location, speed and whether the driver is applying the brakes. The announcements were made Sunday at the opening of the Intelligent Transportation Society World Congress being held in Detroit this week. They are part of a barrage of similar declarations that are expected from other companies throughout the week as the industry shows off progress toward self-driving and safer cars. The freeway system, dubbed "Super Cruise," uses cameras and radar to keep the car in the center of a lane and also stay a safe distance behind cars in front of it. The system will bring the car to a complete stop if traffic halts without driver action, and it can keep the car going in stop-and-go traffic. Other automakers, such as Mercedes-Benz, now offer similar systems that work at low speeds, but GM says it's the first to announce a system that operates at highway speeds. Others could have freeway systems in two years, though. "If the mood strikes you on the high-speed road from Barstow, California, to Las Vegas, you can take a break from the wheel and pedals and let the car do the work," CEO Mary Barra said in remarks prepared for the conference's keynote address on Sunday. But GM said the car still won't drive itself, and the company is working on a system to monitor drivers to make sure they're still paying attention. Details of that system weren't released. "Sensing technology is not yet to the point where the driver can check out," said John Capp, GM's director of global safety strategy. "This is a level of automation that can be done, that is feasible." The new Cadillac that will get Super Cruise hasn't been officially announced yet. But executives have hinted that GM will build a big rear-drive Caddy to lead its lineup in the coming years. Also Sunday, the Michigan Department of Transportation announced that it will partner with GM, Ford Motor Co.

Cadillac shows dealers convertible rendering

Cadillac is getting serious about revitalizing and expanding its lineup, and to that end, a new report claims that brand boss Johan de Nysschen has been showing plans for several new models to the marque's dealer body - among them, a new convertible.
The droptop which Cadillac reportedly showed its dealers in sketch form, would be based on the same platform as the ATS and CTS, those it's unclear to which (if either) of those model lines the new convertible would be added, or whether the design features a canvas or folding hardtop roof. One way or another, it would be the first time Cadillac would offer a convertible since the Corvette-based XLR roadster was discontinued more than five years ago.
Quoting an unnamed brand spokesperson, Cadillac would "like to introduce an open car to the portfolio at some point," however, "it's not likely to be one of the near-term portfolio additions."
