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.

2015 BMW 740Ld xDrive

When it first came stateside in 1978, choosing a BMW 7 Series was a simple process. With one engine and one wheelbase, you could just pick what color you want and be on your merry way. Today there are ten different models, forcing drivers to choose among four engines (plus a hybrid), rear- or all-wheel-drive, and two different wheelbase lengths. As if this isn't tricky enough, the options list has more custom choices than the Taco Bell app. Do you want standard paint and upholstery, or something from the pricey BMW Individual collection? What about the headlights: Do you want LEDs, or are the standard xenons just fine? Need a head-up display? Night vision? Adaptive dampers? The list goes on and on. After a week with a new version of BMW's flagship sedan, we've sorted out which model you actually want, although it's still up to you whether or not to order a ceramic-glazed iDrive knob. Our favorite 7 Series is now the 740Ld Xdrive, a conclusion we came to after a week at the helm of the smooth, torquey land yacht. Driving Notes When the diesel 7 first arrived at the 2014 Chicago Auto Show, its engine was already familiar to American consumers. It's the same 3.0-liter, turbodiesel inline-six found in everything from the E90 3 Series to the past two generations of X5, as well as the current 5 Series. A robust 413 pound-feet of torque lathered across the rev range, with peak twist available between 1,500 and 3,000 rpm, and the corresponding horsepower tops out at 255. 0͖60 happens in a sedate 6.1 seconds, and for those with autobahn dreams the top speed is a modest 130 mph. While those figures aren't terribly impressive, as is often the case with diesels, the real-world application of the engine's power is far more dramatic. Even small throttle inputs produce a smooth surge of acceleration, making the 740Ld feel a lot quicker than the performance metrics might indicate. Even with the current cheap price of gas, the superior fuel efficiency of a diesel engine is worth noting, especially as this model only costs $1500 more than a 740Li xDrive. The diesel tips the scales at nearly 4,700 pounds, yet it boasts a 31-mile-per-gallon highway rating. It's rated at 23 mpg in the city, while our real-world testing saw returns in the mid-to-high 20s. Simple anecdotes about acceleration and fuel economy figures only convey a small part of the 740Ld's goodness.

Hamann BMW M6 Mirror can now cash the checks its body writes

Anyone remember the Hamann Mirror? Need a refresher? The Mirror is German tuning company Hamann's idea of a BMW M6. It was shown at the 2013 Frankfurt Motor Show as an M6 Gran Coupe, sporting a ridiculous paint job and some meaty, multi-spoke 21-inch wheels.
Consider this car the Mirror Mark 2. Based on the M6 Coupe, Hamann has applied a similar visual theme, using the same 21-inch wheels from 2013. Whereas the Gran Coupe rode around with a stock powertrain, though, there's been no such restraint with the two-door Mirror. A fine 620 horsepower is available from the 4.4-liter, biturbocharged V8, an increase of 60 horsepower. Torque is up as well, from 501 pound-feet to a whopping 560, meaning this M6 has speed to match its looks. Hamann claims the Mirror's newfound grunt allows it to hit 62 miles per hour faster than the standard M6 (we'd certainly hope so), although it won't mention a specific number.
The suspension, meanwhile, has been dropped 1.37 inches, or about a third of an inch lower than the Frankfurt Mirror. That drop is complemented by the Mirror's bodywork, including the exposed, carbon fiber hood and the flared fenders, which can now accommodate the enormous 305/25 rear rubber. Hamann has also paid some attention to the front and rear aerodynamics.
