Chrysler, Nissan looking into claim that their cars are industry's most hackable

A pair of cyber security experts have awarded the ignominious title of most hackable vehicles on American roads to the 2014 Jeep Cherokee, 2014 Infiniti Q50 and 2015 Cadillac Escalade.
Charlie Miller and Chris Valasek are set to release a report at the Black Hat hacking conference in Las Vegas, Automotive News reports. The two men found the Jeep, Caddy and Q50 were easiest to hack based not on actual tests with the vehicles, but a detailed analysis of systems like Bluetooth and wireless internet access - basically, anything that'd allow a hacker to remotely gain access to the vehicle's systems.
Considering this lack of hands-on testing, the pair acknowledge that "most hackable" could be a relative term - they point out that the vehicles may actually be quite secure.

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.

Spy photos show Trump's new Cadillac-badged rolling fortress

Development on the new presidential limo, oh-so appropriately nicknamed The Beast, is moving along at a GM proving ground. We got a brief glimpse of the Cadillac-badged rolling testament to safety and security late in February thanks to some clever drone work. We now have a new batch of ground-level photos that show the limo cruising around, presumably being put through the vehicle equivalent of boot camp. Currently, President Trump is making do with the first-generation Beast. While still likely safer than anything else on the road, it's starting to be a bit dated. In addition to the updated styling that makes it look like a comically oversized Cadillac CT6, The Beast v2.0 is likely packing a whole new suite of technology and safety equipment. That's just an assumption, as there's no press release with a full list of features. We can't imagine that the government would want everyone knowing what's beneath The Beast's skin. Expect Trump's ride to have reinforced doors, extra-thick glass, and even a filtration system that would protect against a biological attack. There's speculation that it's equipped with tear-gas cannons, similar to one of James Bond's rides. Even the relatively normal-looking tires are likely to be strengthened in some way, allowing them to still roll if punctured. Add up all of the extra reinforcement, and the truck-based ride is likely to have a mass that's equivalent to a small moon. All that tech doesn't come cheap. Expect The Beast to cost taxpayers somewhere around $1.5 million. Hey, it's still less than the new Bugatti Chiron.
