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 puts e-commerce shopping in car dashboards

DETROIT — General Motors on Tuesday said it will equip newer cars with in-dash e-commerce technology, betting it can profit as drivers order food, find fuel or reserve hotel rooms by tapping icons on the dashboard screen, instead of using smartphones while driving. GM's Marketplace technology, developed with IBM, will be uploaded automatically to about 1.9 million model-year 2017 and later vehicles starting immediately, with about 4 million vehicles across the Chevrolet, Buick, GMC and Cadillac brands equipped with the capability in the United States by the end of 2018, GM said. GM will get an undisclosed amount of revenue from merchants featured on its in-dash Marketplace, Santiago Chamorro, GM vice president for global connected customer experience, said during a briefing for reporters. Customers will not be charged for using the service or the data transmitted to and from the car while making transactions, he said. "This platform is financed by the merchants," Chamorro said. GM will get paid for placing a merchant's application on its screens, and "there's some level of revenue sharing" based on each transaction, he said. It is too soon to say how much revenue GM could realize from the Marketplace system, he said. The GM Marketplace will compete for customer clicks and revenue with hand-held smartphones, which offer a far richer array of applications than the GM system will at the outset. Amazon.com is partnering with other automakers, including Ford, to offer in-car e-commerce capability through Amazon's Alexa personal assistant system. For example, GM will launch Marketplace with just Shell and Exxon Mobil icons in the fuel category. The only restaurant available for in-car table reservations at launch is the chain TGI Fridays, GM said. In addition, there will be apps for parking, and ordering ahead at coffee shops and restaurants such as Starbucks, Dunkin' Donuts and Applebee's. "We will be adding more vendors," with some coming in the first quarter of 2018, Chamorro said. In addition, he said GM plans to expand integration into its vehicles of music, news and other information services. GM also hopes to use its in-car Marketplace connections to expand purchases of products and services, such as additional access to in-car wifi, from its own replacement parts business and dealer network. Customers can "expect to see more service promotions coming through the platform," Chamorro said. Reporting by Joe WhiteRelated Video:

Cadillac is returning to endurance racing with a new prototype in 2017

In two months, Cadillac will return to top-tier endurance racing with its all-new Daytona Prototype International racecar after 14 years away. The car, which adheres to IMSA's new DPi regulations, looks as long, low, and Cadillac-like as anyone could have hoped. It's set to debut at the Rolex 24 at Daytona and will compete head to head with the likes of Mazda and Nissan in what is shaping up to be one of the most diverse and exciting forms of American motor racing in years. The new car will be run by Wayne Taylor Racing, the team that previously fielded the Corvette Daytona Prototype. Wayne Taylor himself has won the 24 Hours of Daytona twice, in 1996 and 2005. He now manages the team and leaves the driving duties to his two sons, Ricky and Jordan. They'll be joined in the cockpit by Max Angelelli, Wayne Taylor's teammate in 2002 at Cadillac's last unsuccessful attempt at endurance racing. To understand Cadillac's new car, officially called the DPi-V.R., you need to understand IMSA's DPi category. Basically, manufacturers are allowed to base their car on one of four chassis that follow the FIA LMP2 regulations. The chassis come from either Dallara, Onroak Automotive, ORECA or Riley/Multimatic. Cadillac will base their car on the Dallara platform. The DPi regulation differ from the LMP2 in two major ways: non-standardized engines and the ability to change certain parts of the bodywork. The DPi regulations are intended to give the variety of the top-tier LMP1 cars at a fraction of the cost. When it came to choosing an engine, Cadillac wanted to power the new car with something kinda sorta production based. The new car will use a naturally aspirated 6.2-liter pushrod V8 that shares some base architecture with the engine in the current CTS-V. While the power output hasn't been announced, expect about 600 horsepower. While that's down compared to the CTS-V, there is far less mass to move around as the Dallara chassis is a svelte 2,050 lbs. Since all the teams will be running different engine configurations, expect restrictors of some sort to help balance the power disparity. The parts of the body work that can be modified - The nose, sidepods, rear wheel arches and rear valance - have all been designed to mimic Cadillac roadcar design elements. Even the wheels look like they were pulled straight from the CTS-V. The front splitter, the floor, and the diffuser are common elements shared with other DPi cars.
