BMW's Connected Drive feature vulnerable to hackers

BMW is working to fix a cyber-security flaw that has left 2.2 million vehicles worldwide vulnerable to hackers. Cars equipped with the automaker's Connected Drive remote-services system are affected, according to the German Automobile Association (ADAC), which first discovered the problem. Researchers found they could lock and unlock car doors by mimicking mobile communications and sending phony signals to a SIM card installed in affected vehicles. An attack could be launched "within minutes" of accessing the system without the perpetrators leaving a trace, according to their report, in part because once they had gained access to the network, the communications were not secure. In response to the security gap, BMW says it has been upgrading software via over-the-air updates over the past week, so no visits to dealerships are needed to remedy the security hole. In fact, owners of affected cars may not have even noticed the updates taking place. The problem affects BMW, Rolls-Royce and MINI vehicles equipped with Connected Drive since 2010. Flaws were first reported to BMW last year by ADAC, which is the country's equivalent of AAA. ADAC says it withheld a public announcement until the car company could address the problem. While BMW has pushed the software patch to most affected vehicles, the organization said it's possible some at cars in the United States had not yet been updated. BMW did not respond to a request for comment Monday. In a written statement, the automaker said it knows of no real-world breaches. 2015 Off To Dubious Start The hack could raise the eyebrows of industry leaders: Cars are now the equivalent of mobile computers and cyber-security experts have been warning that the auto industry has been slow to close its security holes. BMW's breach marks the second time in 2015 that researchers have found a popular automotive feature with little or no security precautions. Last month, experts said a popular device made by Progressive Insurance that allows motorists to track their driving habits contained no security whatsoever. Like the Connected Drive smart-phone app, many automotive components and infotainment features were conceived and produced at a time when industry executives never considered the possibility someone might want to hack into them. But increased connectivity brings increased risk. Going forward, BMW says its Connected Drive features will now operate by using encrypted communications via the HTTPS protocol.

2021 Rolls-Royce Ghost has a fascinating new part to make it one of the most comfortable cars in the world

One of the neat things about Rolls-Royce is the extraordinary lengths the company will go to for maximum comfort. It's like how supercar builders will look for every little advantage to make their cars a tenth of a second faster. On the 2021 Rolls-Royce Ghost, the company is employing something called the Planar Suspension System, a nebulous designation for the collection of systems and parts employed. Some are straight forward, such as the four-wheel independent air suspension, and the way the GPS and forward cameras inform what level of firmness should be employed on the road. But one part left us perplexed: the upper control arm damper. We spoke to Jon Simms, lead engineer for the Ghost, for more information, and now we have a better grasp on what it is and what it does. As for what it is, it's the roughly horseshoe-shaped object highlighted in purple in the above photo. The yellow parts are bumpstops, and it's mounted on the same joint as the upper control arm. And it turns out it's a pretty simple piece of equipment. It works very much like the harmonic balancer on the end of an engine. It's a weight with a rubber-y flexible hinge, and going over smaller bumps, it absorbs some of the extra vibration and movement from the suspension. Those bumpstops in yellow give the damper some extra purchase on the control arm, and they absorb impacts from larger bumps that may move the control arm suddenly so that the arm and damper don't bang into each other. This may seem like a pretty minor thing, but remember, Rolls-Royce and its buyers are out for maximum comfort, so there's reason to invest in ironing out every possible ride quality issue, no matter the size. And even if it's a minor improvement, that's not necessarily a bad thing. Simms told us that existing Ghost customers they talked to during development had one key request about the driving experience: "don't break it." So making sure that the new car was basically like the last one, but a bit better, would seem to be what customers would want. 2021 Rolls-Royce Ghost View 29 Photos The Ghost is the first Rolls-Royce to adopt this full suite of Planar Suspension System parts, though other Rolls-Royce models have had pieces of the system. And considering the fact the Ghost shares its platform with the Phantom and Cullinan, now, we wouldn't be surprised if later versions of those models pick-up parts like this damper. Related Video:

Could Rolls-Royce expand business with new models?

Rolls-Royce may be forced to expand its lineup beyond the über-luxury cars gobbled up by the ultra-wealthy jetset, as new competition in the form of the rumored, high-end Mercedes-Benz S-Class could take a slice of the luxury pie from the BMW-owned manufacturer.
Automotive News reports that this, along with the combination of BMW's unwillingness to move above the price-point set by the 7-Series and Bentley's expansion into the SUV realm, could force Rolls-Royce's hand. AN is arguing that, as unrealistic as it might sound, Rolls could develop a four-door crossover or shooting brake, but that any such plans are in the earliest of stages.
In the near term, the smallest Rolls-Royce, the Ghost, will get a refresh in 2014, while the sporty Wraith fastback will spawn a convertible variant by 2015. The big boy of the Rolls-Royce range, meanwhile, is due for a far more comprehensive re-do. The Phantom is expected to share a platform with the next-generation 7-Series in 2016. Advanced materials are expected to feature heavily, as Rolls-Royce seeks to trim body fat and improve fuel economy without compromising the performance or comfort expected of the brands' flagship model.
