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.

2016 BMW M4 GTS hidden in plain view in Tokyo

We almost missed the 2016 BMW M4 GTS at the Tokyo Motor Show. As you can see in the photos, the car is sort of tucked into a little corner behind a wall, and it's way in the back of BMW's show stand. You'd never see it unless someone told you it's there. And that's a shame. This is one of the coolest cars BMW has launched in quite some time. Only 700 examples of the M4 GTS will be sold globally, with 300 earmarked for the United States. Aside from the aerodynamic and appearance upgrades, the GTS stands out by being the first production road-car to use a water injection system. We detailed this technology when the M4 GTS officially bowed, but the end result is more power. The GTS makes 493 horsepower and 442 pound-feet of torque – gains of 68 hp and 36 lb-ft over a stock M4. The other big news for the M4 GTS is its weight reduction – some 200 pounds have been removed, thanks to the use of carbon fiber-reinforced materials. The car's rear seats are gone, and several interior pieces have been redone in lighter materials, as well. This thing should be a monster out on the track, and we can't wait to get behind the wheel. But first, we're hoping BMW at least lets it out into the spotlight a little. See the car for yourself, live from Tokyo, in the gallery above. The new 2016 BMW M4 GTS an exclusive high-performance special edition M4 available for the first time in the US. - First production road car with a Water Injection System - World-exclusive OLED light technology - Specially designed full three-way adjustable M coilover suspension - Intelligent lightweight body design - Most agile, radical and powerful M4 ever Woodcliff Lake, N.J.: BMW today announced the new 2016 BMW M4 GTS giving BMW M GmbH a new and exclusive technological masterpiece which elevates the potential of the BMW M4 Coupe to an impressive new level. With its powerful, motorsport-inspired looks and high-performance technology, the BMW M4 GTS has its sights set squarely on the race track. Thanks to an innovative water injection system helping boost power to 493 bHP and track ready chassis, this Special Edition M vehicle recorded a lap time of 7 minutes 28 seconds around the legendary Nurburgring-Nordschleife, the world's most challenging race circuit, making a clear statement about this model's exceptional dynamic abilities. At the same time, the sharpest BMW M4 of all can also hold its own on public roads.

BMW dishes on 'lightweight' 2014 M4

BMW's M cars are not what we'd call featherweights. Sure, the big, bruising twin-turbocharged V8s deliver a lot of power, but the fact of the matter is that more weight often equates to less fun.
Which is why we're so excited over a recent sit-down the blokes at Top Gear had with BMW's product manager for small and medium cars, Matt Collins. The chat led to talk of the M3 Coupe replacing M4. Collins confirmed that, yes, the new M4 would be turbocharged. The new engine will also be a six-cylinder, which should make purists happy.
