2014 BMW 740Ld xDrive does diesel in a big way

Slowly but surely, BMW is expanding its lineup of diesel-powered models here in the United States. In addition to the 328d sedan and wagon, 535d sedan and X5 xDrive35d crossover, we now have this, the BMW 740Ld xDrive (not to mention the refreshed 2015 X3 xDrive28d that also makes its debut here in Chicago). As its name - and the photos above - suggest, this means BMW is offering diesel power in its flagship, long-wheelbase 7 Series sedan, set to directly compete with the likes of the excellent Audi A8 TDI.
Under the hood is BMW's familiar 3.0-liter turbocharged diesel inline-six, delivering 255 horsepower and 413 pound-feet of torque, all of which is sent to the road via the company's xDrive all-wheel-drive system and ZF eight-speed automatic transmission. That torque thrust is available straight away from 1,500 rpm, and BMW says the 740Ld xDrive will sprint to 60 miles per hour in a very respectable 6.1 seconds. Official fuel economy estimates haven't been released yet, but we expect the car to net highway fuel economy ratings in the mid-30 range.
The 740Ld xDrive arrives in BMW showrooms this spring, priced from $82,500, not including $925 for destination. We're pretty stoked to drive it. But in the meantime, have a look at fresh images of the big sedan live from the Chicago Auto Show, above.

BMW solar roof helps i3 drivers even when sun isn't shining

At the Consumer Electronics Show, BMW has announced a release window for its i Wallbox Pro that unites domestic solar power and the electricity grid. The box itself was shown off during last year's i8 drives and it rests inside a solar carport to control the simultaneous delivery of both solar power and the electric grid energy to recharge an i8. One drive attendee wrote how the Wallbox Pro display showed that it was providing 3.4 total kW to the coupe, with 2.8 kW from the sun and 0.6 kW from the grid. At CES, BMW said the i Wallbox Pro, brought to life by BMW DesignWorks, will be available in 2016. For homes that aren't equipped with solar power, or when solar isn't available, the system will draw power from the grid when it's least expensive. The Munich manufacturer also announced a concept storage solution using discarded batteries from its electric cars, where excess energy from solar or other sources could be held for later use for a vehicle or the home itself. BMW will be demonstrating the i Wallbox Pro at CES and the press release below has more information. BMW i Home Charging Services unveiled at the CES Consumer Electronics Show in Las Vegas Pioneering integrated charging solution for electric vehicles brings further reduction in charging costs and integrates home solar generating systems with the household electricity system. Munich / Las Vegas- January 5, 2015... At the Consumer Electronics Show CES 2015 in Las Vegas (6 – 9 January 2015) BMW i will unveil a further innovative product from its 360° ELECTRIC portfolio: BMW i Home Charging Services. This smart solution for home charging of electric and plug-in hybrid BMW models is based on the smart home-enabled BMW i Wallbox Pro system already presented by BMW in spring 2014. How the smart charging service works. Using BMW i Home Charging Services, the vehicle is charged with homegenerated solar power whenever this is available. At other times, or if the household does not have a solar generating system, the vehicle is automatically charged at the cheapest off-peak rates. This makes it possible to take advantage of flexible electricity pricing that varies depending on the time of day. In the USA, this can result in savings of up to 800 dollars a year. With this fully automated charging service, customers get a simple-to-operate system that integrates vehicle charging with the household electrical system and online-based data systems.

More automakers working to turn your smartphone into a shareable digital car key

The smartphone killed the phone book, audio player, the pocket digital camera, handheld GPS devices and voice recorders. Now that addictive, transistor-filled candy bar is coming for your car keys. The Car Connectivity Consortium (CCC) announced that it's unveiled Digital Key Release 1.0 Specification for its member companies, which is the first step in standardizing protocols. As of now, the potential is there for drivers to download a digital key that can lock and unlock the car, start it, and transfer the key to another operator in order to share the car. The CCC's aim is to save development costs, stave off a glut of similar-yet-competing technologies, and create keys that reflect the expanded use cases for cars, i.e., car-sharing services and to-your-car delivery. Next year's Release 2.0 Specification will standardize an authentication protocol between the phone and the vehicle — how a digital key is generated on a secure server and transmitted to the car and the device — and "promise more interoperability between cars and mobile devices." The CCC says that "NFC distance bounding and a direct link to the secure element of the device" will assure security. We take that to mean the phone will need to be in direct contact with the vehicle, at least to open the door. Carmakers and suppliers have been working on digital keys for years now, and the ecosystem for individual owners to open individual cars is growing. Audi showed off its Mobile Key at the 2015 Consumer Electronics Show, and now calls it Audi Connect Key, but we haven't seen much of it in the field. That same year, Volvo said it expected to sell cars with digital keys only by 2017, which clearly didn't happen. Last year, the head of sales at BMW asked, "Honestly, how many people really need [keys]? They never take it out of their pocket, so why do I need to carry it around?" Even though a digital key offers an owner more convenience and long-distance control over their vehicle, car sharing is the target — and that can even include traditional rental cars. In 2013, Continental began testing a digital key in France, aimed at integrating and simplifying the electric-car-sharing business; everything from finding a free vehicle to driving it and charging it could be done on a phone. A key could be programmed with the driver's information, so that any car the driver gets in will be automatically updated with that driver's preferences, say for audio or seating position.
