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.

Lexani Motorcars unveils plans for 2021 Cadillac Escalade Mobile Offices

Lexani Motorcars is an aftermarket shop that specializes in high-end luxury customizations for a variety of large SUVs and vans. The Corona, Calif. company aims for business-class-type vehicles, rather than "Pimp My Ride" hack jobs, and has recently been working on 30-inch extended mobile office conversions, among other projects. Up next: the 2021 Cadillac Escalade. Lexani Motorcars, not to be confused with Lexani wheels, took to Instagram to show off a vision for a custom office setup for the new-generation 2021 Escalade. Cadillac's large SUV would be extended by 30 inches and outfitted with a plethora of over-the-top luxury options. Lexani's most extreme additions include armoring, but their toys don't have to be that serious. The most immediately noticeable feature in the Escalade is the starlight headliner. Similar to what's seen in certain modern Rolls-Royces, the starry ceiling is not necessarily a new feature for Lexani Motorcars, but the design has evolved. This most recent interpretation looks like it has a specialized design, possibly one that mimics a real part of the sky.  The Mobile Office includes four massive captain's chairs, each of which has motorized functionality and quilted leather. In between each set of seats is an integrated iPad tablet, and more are seen built into the walls of the SUV. Each seat also has a fold-out desk and foot rests for reclining.  Furthermore, the Mobile Offices include hideaway big-screen TVs that pop up behind the rear seats. Other options include satellite, curtains or shades for the windows, custom trim pieces made out of high-end materials such as carbon fiber or real metals, cooled storage for drinks, and storage compartments for libation stemware. Lexani Motorcars does not list a price, as each car is configured per the customer, and it does not mention when the new Escalades will become a reality. The Escalade was originally estimated to launch in late 2020, but it's unclear whether or not that will be affected by the current production stoppages due to coronavirus.           View this post on Instagram                   Now accepting pre-orders on 2021 Escalade Mobile Offices ?

MIT puts V2V technology on its 2015 Top Ten list

Of all the technologies swimming around the automotive world, it is vehicle-to-vehicle communication that the Massachusetts Institute of Technology has fished out as one of its Ten Breakthrough Technologies of 2015. It joined emerging tech like brain organoids, supercharged photosynthesis, and Project Loon on the list, and got the nod over autonomous driving because, as the MIT Technology Review wrote, V2V communication "is likely to have a far bigger and more immediate effect on road safety." How so? Because actual cars transmitting data like their location, speed, steering angle, and state of braking to one another at least ten times per second provides a greater degree of awareness than sensor readings and algorithms. The US Department of Transportation and the National Highway Traffic Safety Administration have been working for years on standards and a regulatory schedule for introducing V2V to the marketplace, and Cadillac plans to incorporate V2V into at least one of its vehicles by 2017. Since we've begun the year with a number of stories of cars being hacked into, that got us wondering about the security of V2V communications. In a recent piece by our own Pete Bigelow on what motorists should know about getting their cars hacked into, he wrote that although cyber break-ins are extremely difficult, expensive, and time-consuming to do remotely, V2V is "one more conceivable avenue a hacker could use to impact multiple cars at a given time." So we spoke to Wilmington, Massachusetts-based Security Innovation about it. The automotive consultancy company has been working with the DOT since 2003 on V2V technology and the issues around it - namely security and privacy - and its chief scientist, William Whyte, is the technical editor of the Institute of Electrical and Electronics Engineers (IEEE) 1609.2 standard outlining its security protocols. Those protocols are expected to be finalized by the DOT toward the end of this year and then come into effect in 2016, and the company's Aerolink product is the security solution Cadillac will use. Whyte said, "If you hack into a car, V2V is the hardest place to start," and Pete Samson, the general manager of Security Innovation's automotive team, said "There are ten or 12 alternate attack surfaces" around the car that would make much easier targets.
