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.

J.D. Power study sees new car dependability problems increase for first time since 1998

For the first time since 1998, J.D. Power and Associates says its data shows that the average number of problems per 100 cars has increased. The finding is the result of the firm's much-touted annual Vehicle Dependability Study, which charts incidents of problems in new vehicle purchases over three years from 41,000 respondents.
Looking at first-owner cars from the 2011 model year, the study found an average of 133 problems per 100 cars (PP100, for short), up 6 percent from 126 PP100 in last year's study, which covered 2010 model-year vehicles. Disturbingly, the bulk of the increase is being attributed to engine and transmission problems, with a 6 PP100 boost.
Interestingly, JDP notes that "the decline in quality is particularly acute for vehicles with four-cylinder engines, where problem levels increase by nearly 10 PP100." Its findings also noticed that large diesel engines also tended to be more problematic than most five- and six-cylinder engines.

Cadillac prepares to top its own 'Ring record with upcoming new CTS-V

It was a big deal back in 2008 when the original Cadillac CTS-V clocked a lap time of 7:59 at the Nürburgring, making it the fastest sedan ever to lap the Nordschleife to that date. Not many four-doors have bested that time since - the list consisting pretty much only of the Porsche Panamera Turbo - but now hot hatches are lapping faster than that, so you can bet that the new one will manage an even better time.
Now we've spotted the upcoming new CTS-based performance sedan several times before undergoing testing in locations around the world, but this is the first time we've seen it at the Nürburgring, apparently using the Goodyear Dunlop test facility as its base of operations (and still wearing Michigan manufacturer plates, incidentally). Considering how well the outgoing CTS-V performed and how much further you can bet Cadillac will push the envelop this time around, a new sedan lap record is almost a certainty - and we can only hope for an all-out war between Europe's performance sedan power houses to ensue.
