Audi introduces leaner, fitter second-generation Q7

After a long run on the market, Audi has finally signaled the end of the first-generation Q7 with the introduction of the long-awaited second-gen version of the brand's first crossover. The 2016 Q7 is a far lighter machine than the vehicle it replaces, thanks to ample use of hot-shaped steel and aluminum. Beyond that, the Volkswagen Group's MLB platform will allow the fullsize Audi to accommodate a range of engines, including more potent versions of the US market's 3.0-liter, supercharged V6 and 3.0-liter TDI. On top of that, the next-gen Q7 will also be available as a diesel plug-in hybrid, complete with a version of the brand's Quattro all-wheel-drive system. The Q7's new design, meanwhile, gives the car an almost wagon-like appearance and profile. The "Singleframe" grille is wrapped in an aluminum-looking surround, not unlike Audi's smaller RS Q3. Audi's cleanly styled headlights flank it, while the large taillights aren't as aggressively angled as Audi's other crossovers. The cabin is lavish, featuring a typically stylish design with plenty of tech. A 12.3-inch TFT display takes the place of a conventional instrument cluster, while the center stack is crowned by its very own display. Even the HVAC display controls are handsome. You can see exactly what we mean in our gallery of live images of the new Q7, straight from the floor of the 2015 Detroit Auto Show.

Genesis G70 vs sport sedan rivals: How it compares on paper

We got our first look at the Genesis G70 sport sedan today. We think it looks good, with enough ties to its fellow Genesises (Geneses?) to further establish the brand and just enough distinction to help it stand out from the crowd. But ah yes, the crowd. Although Genesis didn't release the G70's full spec sheet, it revealed just enough for us to start sizing it up to its future competition. There are certainly others with which to compare (Lexus IS, Cadillac ATS, Alfa Romeo Giulia, Jaguar XE just to name a few), but we decided to take a look at the best sellers and most competitive luxury sport sedans. (And hey, if you like this, we can always do a follow up) So, here we have the Genesis G70 vs BMW 3 Series vs Audi A4 / S4 vs Mercedes-Benz C-Class vs Infiniti Q50. Nothing like a good chart to dig your teeth into on a Friday. Note that we only compared those models that line up with the G70. So, we left out the BMW 320i and Audi A4 Ultra entry level models as well as the Q50 3.0t mid-grade model that's considerably cheaper than the German performance upgrade models we listed. All 0-60 figures are rough estimates based on several sources, models/drivetrains and OEM figures.

Audi creates new diesel fuel from carbon dioxide and water

What if you could power cars of the future with pollution created by the cars of the past? That's what German automaker Audi is hoping to achieve by creating a new synthetic fuel using renewable energy to turn water and carbon dioxide gas into a new kind of fuel they call "e-diesel." The new diesel is being produced at Audi's pilot plant Sunfire in Dresden, Germany. Only a few gallons were created, which the German Federal Minister of Education and Research Johanna Wanka put into her Audi A8 to prove the fuel's bonafides. The base fuel is known as "blue crude" and begins from a green source. Audi uses electricity from wind, water or solar power sources to separate hydrogen from oxygen in water. The hydrogen is then mixed with carbon dioxide which has been converted in carbon oxide. The blue crude is then further refined to create the e-diesel. The carbon dioxide is currently supplied by a biogas facilities, but some of that CO2 was captured from the air. "The engine runs quieter and fewer pollutants are being created," says Sunfire CTO Christian von Olshausen. The fuel can be combined with conventional diesel fuel, as biodiesel fuels already and would be competitively priced against regular diesel, according to Gizmag. Sunfire can produce about 42 gallons of e-diesel a day. That seems like barely a drop in the bucket in terms of Europe's energy use, but Audi is ready to commercialize the technology with plans to expand production with a bigger facility in the future.
