2017 Audi A4 2.0T Quattro Second Drive

Never mind the impending bubble burst, it's technology's time and Audi couldn't be happier. The 2017 A4 is the latest attempt to prove beauty and brawn can't beat intelligence outright. And this is the company's best case in 20 years. For two decades, the A4 has been the backbone of Audi's lineup and key in its resurgence in the post-Unintended Acceleration days. This car has managed to build up a successful following by being an alternative to the more popular BMW 3 Series and Mercedes-Benz C-Class while being nearly as good, if not actually better, than the competition. Audi chose to stake a claim in simple clothes covering technology that was more intuitive than some, being different without being difficult. But Audi is as much a part of the establishment as its big rivals now, so it's not getting any alternative breaks anymore. It's the young tech startup that's finally a grownup – and learned to dress like one. While Jonathon Ramsey got to drive this new A4 last fall in Italy, Audi sent me to San Diego last week to drive the US-spec model that goes on sale in a couple of weeks. And, in short, if you liked the old A4, you'll really like this one. If you liked the old A4, you'll really like this one. The fact this model is known internally at Audi as "B9" is a coincidence when you think about its exterior design. The new A4 is certainly attractive, but you'll have to be a huge Audi aficionado to differentiate this over the old car at a glance. And I dare you to find someone who's actually offended by any part of the design. Some creases lower down on the side of the new car help eliminate the bloated look of the outgoing model, without adding too much fuss. Audi still has Acura beat in the "precision" race. Other new details of note are a wider grille and slimmer headlights (xenons are standard, full LEDs optional) that make the front of the A4 look lower than before, and new sequential turn signals out back that are just fun to watch in traffic. Changes are far more noticeable inside. The tall, somewhat slab-sided dash of the old car is gone and replaced by something with a more airy feel that we've seen in the TT and Q7. There's less of a black dash to get in the way of the expansive windshield and generous side glass, all unusual in today's automotive landscape. You're going to enjoy the fact you can see out of the A4.

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.

Audi's lunar rover is nearly ready for the moon

Last year, Audi announced it was working on a lunar rover with a group called the Part-Time Scientists. Now the company says the design of its Lunar Quattro is complete, and all that's left is final testing before it's ready to head for the moon. Since Audi and its 16 engineers became involved with the project, the rover has actually increased in size, as have its tires. The company says this is for added stability. Despite the added size, the rover is now lighter, bringing it down from 38 to 30 kilograms (what we'd call 66 pounds). Otherwise, the rover is generally the same as it was last year. All four wheels are still powered by electricity, so Audi touts it as being both a Quattro and an E-tron vehicle. Cute. The rover will undergo final testing in the Middle East where it will run through simulations of the mission. For those unfamiliar, the mission parameters were set by Google for the Google Lunar XPRIZE. The prize is worth $30 million and will go to the first team to land a privately funded lander and rover on the moon, drive the rover 500 meters, and send back photos. If the mission is successful, we should get some great 3D and 360-degree shots of the lunar rover left behind by the Apollo 17 mission in 1972, since the proposed landing site is nearby. The Part-Time Scientists team that Audi partnered with has also booked a launch for its ALINA lunar lander, which will carry a pair of the Lunar Quattro rovers to the moon's surface. The launch was scheduled with Spaceflight Industries and is set for the end of 2017. Spaceflight Industries has managed 11 rocket launches with different companies and rockets between 2013 and 2015, and will also launch a probe from Israeli XPRIZE competitor SpaceIL sometime next year on a SpaceX Falcon 9 rocket.
