Audi Q7 E-Tron Quattro TDI Quick Spin

The operating word is quiet. This refers both to the sound inside the cabin of the upcoming Audi Q7 E-Tron Quattro TDI – even with the diesel engine running – and the company's public statements about its plan for this powertrain in the United States. Basically, while Europe is getting the diesel plug-in sometime next spring (a bit of a delay), all we know for sure right now is that the US will be getting the Q7 E-Tron, probably in 2018, and it will have either a 3.0-liter turbodiesel or 2.0-liter turbocharged gas engine. You may now place your bets as to which one you think the public (or, more likely, CARB) will go for. We're guessing 2.0T. Despite not knowing if we'll ever see this E-Tron TDI on our side of the Atlantic, we recently spent an enjoyable morning tooling around the hills outside Madrid, Spain. As we said, this beast is seriously quiet, and impressively so. Driving Notes The Q7 is a big vehicle, but with powertrain that combines electric motors and diesel thrust, there's a ton of low-end torque. The official 0-62 time is 6.0 seconds, which is basically the same as the 6.1 seconds of the non-PHEV Q7. The Q7 E-Tron is about 500 pounds heavier than the already-4,700-pound Q7, but because of its trick powertrain, never felt sluggish in the hills of Spain. This Q7 E-Tron is a parallel hybrid, with the 3.0-liter TDI diesel engine and the 94-kW disc motor both able to drive the wheels. Overall, they provide 373 horsepower and 516 pound-feet of torque. Despite the parallel system, the not-quite-powerful-enough electric motor doesn't provide the complete electric drive experience that EV fans might be looking for. For example, the Q7 E-Tron has a top speed of 139.8 mph, but that's only in hybrid mode. In EV mode, its top speed is just 78 mph. Audi's Virtual Cockpit display, first seen in the TT, remains an ideal way to give you a wealth of information in an easy-to-see format. It's just as slick in the Q7, where you can toggle the size of the gauges and then pick what you want the screen to focus on, whether that's speed limits, infotainment information, powertrain usage, speed, or navigation.

Mercedes could make EV batteries with Audi, BMW

It's not a big leap from digital maps to batteries, it turns out.The head of Mercedes-Benz parent Daimler said recently that he envisions his company working together with German automotive competitors BMW and Volkswagen to further accelerate electric-vehicle battery technology. The three automakers recently worked together to enhance their in-car maps systems. Daimler CEO Dieter Zetsche talked about "commonalities" between automakers, not the least of which is the need for all of them to achieve increasingly stringent fuel-economy requirements in the European Union, at the Frankfurt Auto Show last week, according to Reuters. While these companies have made their own inroads as far as plug-in vehicles go, they are all behind the Renault-Nissan Alliance when it comes to public deployment of electric vehicles. This summer, Daimler, Audi and BMW hooked up to acquire the Nokia Here digital-mapping service for about $2.8 billion. The triad of automakers beat out companies such as Apple and Uber to buy the entity, which was founded in 1986 as Navteq. Nokia bought the company in 2007. The acquisition makes sense as the automakers work on improving their products with features like cloud-based data to warn drivers of icy roads and traffic jams. The technology will likely also eventually be used in autonomous vehicles. Automakers working together for a common goal of improved technology is nothing new, of course. General Motors and Honda agreed in 2013 to work together to accelerate hydrogen fuel-cell drivetrain development. Earlier that same year, Daimler said it would work with Ford and Nissan in a separate collaboration to speed up the development of hydrogen fuel-cell technology. Related Video:

Translogic 164: Driving the fuel cell vehicles of the 2014 LA Auto Show

The LA Auto Show is known for its environmentally friendly vehicle debuts. At last year's show, hydrogen fuel cell concepts from Honda and Toyota joined a lease-ready Hyundai Tucson FCEV to cast a green hue over the convention center. This year, automakers took us a step closer to a fuel cell future by offering drives of their hydrogen-electric hybrids. Translogic host Jonathon Buckley takes a ride in the Toyota Mirai, which is headed for production in 2016. He follows that with a spin in the Volkswagen Passat HyMotion and the Audi A7 Sportback h-tron quattro concept. Which of these fuel cell vehicles holds the most promise? Tune in to find out.
