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.

A car writer's year in new vehicles [w/video]

Christmas is only a week away. The New Year is just around the corner. As 2014 draws to a close, I'm not the only one taking stock of the year that's we're almost shut of. Depending on who you are or what you do, the end of the year can bring to mind tax bills, school semesters or scheduling dental appointments. For me, for the last eight or nine years, at least a small part of this transitory time is occupied with recalling the cars I've driven over the preceding 12 months. Since I started writing about and reviewing cars in 2006, I've done an uneven job of tracking every vehicle I've been in, each year. Last year I made a resolution to be better about it, and the result is a spreadsheet with model names, dates, notes and some basic facts and figures. Armed with this basic data and a yen for year-end stories, I figured it would be interesting to parse the figures and quantify my year in cars in a way I'd never done before. The results are, well, they're a little bizarre, honestly. And I think they'll affect how I approach this gig in 2015. {C} My tally for the year is 68 cars, as of this writing. Before the calendar flips to 2015 it'll be as high as 73. Let me give you a tiny bit of background about how automotive journalists typically get cars to test. There are basically two pools of vehicles I drive on a regular basis: media fleet vehicles and those available on "first drive" programs. The latter group is pretty self-explanatory. Journalists are gathered in one location (sometimes local, sometimes far-flung) with a new model(s), there's usually a day of driving, then we report back to you with our impressions. Media fleet vehicles are different. These are distributed to publications and individual journalists far and wide, and the test period goes from a few days to a week or more. Whereas first drives almost always result in a piece of review content, fleet loans only sometimes do. Other times they serve to give context about brands, segments, technology and the like, to editors and writers. So, adding up the loans I've had out of the press fleet and things I've driven at events, my tally for the year is 68 cars, as of this writing. Before the calendar flips to 2015, it'll be as high as 73. At one of the buff books like Car and Driver or Motor Trend, reviewers might rotate through five cars a week, or more. I know that number sounds high, but as best I can tell, it's pretty average for the full-time professionals in this business.

Cadillac says it made CUE infotainment a lot better

We've never been huge fans of CUE, the Cadillac User Experience infotainment interface. It's been around a few years now, and the best thing we can say for it is that it now supports Android Auto and Apple CarPlay, making it easy enough to replace most of the interface with a familiar smartphone-based system. Now Cadillac has made some big upgrades to the system that should address at least some of our concerns. First and foremost, the system is claimed to be more intuitive, with a more logical interface design. Cadillac has added a Summary View that gives an overview of the climate, media, navigation, and phone all at the same time. The system will also be able to receive over-the-air updates, allowing Cadillac to make improvements more often and push them out to owners' cars, mush like Tesla and other automakers already do. The 4G LTE connection will also be used to connect the car with the cloud, where drivers can store and modify their own personalized set of settings. This My Driver Preferences profile will include things like contacts, navigation preferences, and recent destinations, and will also follow them from one car equipped with the system to another. That should come in handy for anyone subscribing to the $1,500-a-month Book by Cadillac vehicle subscription service, which allows participants to swap between cars when they choose. The cloud connection will also carry over to a new available navigation function, which Cadillac claims has a more intuitive, smartphone-like interface. It uses its data connection to provide current destination info and is supposed to learn a driver's habits, such as their preferred routes and frequent destinations, which the system will then attempt to offer up predictively – so the car should be able to know that you're heading home at 5:00. Additional apps for the system will be available through Cadillac's new Collection app store. And it's still compatible with Android Auto and Apple CarPlay. One sore spot that appears to have been improved is the digital gauge package, although Cadillac hasn't offered details on that extension of the system. The current iteration's ability to over-customize the interface (our personal favorite is the option to display a total of four speedometers between the head-up display and the gauge screen; see video below) and unintuitive controls make it difficult to use and learn, while the simulated gauges don't look particularly realistic.
