Check out the trick way you access the tire valve on this BMW Alpina B6

The wheels are one of the first things you notice when checking out the 2015 BMW Alpina B6 xDrive Gran Coupe. The 20-inch aluminum alloy rollers have 21 spokes that spray out from their hubs, creating one of Alpina's signature design features. But there's also plenty of function to go along with the stylistic form of this hotted-up BMW 6 Series Gran Coupe.
By rotating the Alpina roundel and unlocking the center hub, you gain access to the tire valve and bolts, which are hidden inside. They're literally kept under lock and key, and they protect your Alpina's wheels from the elements and theft. This unique center-fill system employing a hollow spoke isn't a new setup for the favored BMW tuner, but since Autoblog had one in our offices this week, we thought we'd take the opportunity to show the unique mechanism in case you haven't seen it before. Check it out in our brief video below.

Car Hacking 101: Here's what motorists should know [w/video]

Cars are nothing more than computers on wheels. As such, they're vulnerable to hackers. Most people who work within the auto industry have understood this for years, but for the broader American public not paying as close attention, three storylines emerged recently that underscored this new vehicular reality. First, German researchers found a flaw in BMWs remote-services system that allowed them to access the telematics units in vehicles. Then, a 60 Minutes report demonstrated that researchers could remotely infiltrate a Chevy Impala and override critical functions, like acceleration and braking. Finally, a US Senator released a critical report (see video above) that found almost all automakers are unprepared to handle real-time hacks of their vehicles. Those reports come on the heels of two previous instances in recent months when researchers demonstrated the capability to hack cars. All this news can be disconcerting. If you're late to the concept of car-hacking and wondering how this is possible, we've got you covered. Here's your quick primer on what you need to know. 1. How Did My Car Become A Computer? On the outside, cars haven't changed all that much over the past couple of decades years. On the inside, however, the amount of electronics and software has dramatically increased. Most new cars contain more than 50 microprocessors known as electronic control units. These ECUs control everything from airbag deployment and navigation systems to throttle control and braking, and they're usually connected to each other on an internal network called the CAN bus. 2. What Exactly Is Car Hacking? Depends who you ask. Automakers might consider anything that alters the car from its state of manufacture as a 'hack.' For example, if you're chipping the engine – re-calibrating those ECUs to increase your horsepower – some people might consider that a hack. But in the context of the recent news reports, security experts are focused on unwanted, unauthorized cyber intrusions into a vehicle. Once inside your car, prospective attacks could range from minor things like eavesdropping on conversations via an infotainment system and unlocking car doors to major concerns, like overriding driver inputs and controlling braking, steering and acceleration. 3. How Is This All Possible? Any part of the car that communicates with the outside world, either via a remote or direct connection, is a potential entry point for hackers.

BMW warns profits will fall, plans $13.6 billion in cost-cutting

FRANKFURT, Germany — BMW said Wednesday that profits in 2019 will be "well below" last year's, and it will cut 12 billion euros ($13.6 billion) in costs by the end of 2022 to offset spending on new technology. The company said profits would be eroded by higher raw materials prices, the costs of compliance with tougher emissions requirements and unfavorable shifts in currency exchange rates. The Munich-based automaker also faces increased uncertainty due to international trade conflicts that could lead to higher tariffs. "Depending on how conditions develop, our guidance may be subject to additional risks; in particular, the risk of a no-deal Brexit and ongoing developments in international trade policy," said Chief Financial Officer Nicolas Peter. The company forecast a profit margin of 6 to 8 percent for its automotive business, short of the long-term strategic target of 8 to 10 percent, which it said still "remains the ambition" for the company if given "a stable business environment." BMW said it had no plans for layoffs even as it outlined cost saving measures that include dropping half of its engine variants as it seeks to reduce product complexity. The BMW, Mini and Rolls-Royce brands are to get a single sales division. Peter said that given the headwinds to earnings, "we began to introduce countermeasures at an early stage and have taken a number of far-reaching decisions." The company said the measures were needed "to offset the ongoing high level of upfront expenditure required to embrace the mobility of the future." Automakers around the world have faced heavy up-front costs for technology expected to change how people get from one place to another in the next decade. Those include electric cars and renting cars through smartphone apps. Yet the returns from such investments remain uncertain and auto companies face competition from tech firms such as Uber and Waymo. BMW made 7.2 billion euros ($8.2 billion) in net profit last year, down 17 percent from 2017, when it booked a gain of $1 billion from U.S. tax changes. The company faced headwinds from increased tariffs on vehicles exported to China from the United States. It also suffered from turmoil on the German auto market when companies faced bottlenecks getting cars certified for new emissions rules. BMW faces uncertainty from U.S.-China trade tensions that could result in new tariffs if talks do not result in an agreement. U.S.
