2015 Audi A8 and S8 get some new goodies

Luxury car buyers are a demanding bunch. They've got this crazy notion that just because they're spending the better part of a hundred grand on a top-tier luxury sedan, they should get the very best and the cutting edge of what the industry has to offer. That has tended to come down to the S-Class even when it had grown long in the tooth, and now that Mercedes-Benz has rolled out an all-new version, the competition is falling all over itself to release updates to keep their flagship sedans in the running. Jaguar did that just yesterday with its XJ sedan, and now Audi has revealed the latest revisions to its A8 range.
Set to debut at the Frankfurt show in just a few weeks from now, the latest A8 (and its performance version, the S8) benefits from a series of stylistic, powertrain, and technology upgrades. Among the most prominent, of all things, are the new Matrix LED headlights that can automatically lower the high-beams for oncoming vehicles, with integrated turn signals that light up to point in the direction the driver's about to turn. But that's hardly the end of the story.
Audi has apparently reduced the output on the 3.0-liter supercharged V6 to from 328 horsepower to 310 but raised the 4.0-liter twin-turbo V8 from 414 hp to 435, which now offers a 0-60 run of just 4.5 seconds. That's just three tenths behind the S8, which remains unchanged at 513 hp, as does the 493-hp 6.3-liter W12. The 3.0-liter TDI is up from 247 hp to 258, the 4.2-liter TDI grows from 345 hp to at 385 (with a massive 627 pound-feet of torque to boot) and the hybrid that offers a combined 245 hp and 354 lb-ft. That makes for one massive array of engines globally, although only some of them will be offered Stateside. Each is mated to an eight-speed automatic transmission and Quattro all-wheel drive, but thanks to the A8's lightweight construction, it's lighter than any other all-wheel-drive model in its class.

2016 Audi S6 and S7 First Drive

Audi paired the S6 and S7 for the purposes of this test in Southern California, but these are rather disparate cars. A three-box sedan, even a sporty one like this S6, is for a specific kind of customer. A sleek, four-door hatchback like the S7, on the other hand, is for a different kind of person. These two people might not be as different as Dr. Jekyll and Mr. Hyde, but at the very least the S7 is the S6's lothario neighbor – the one who's always got a glass of scotch in one hand and a chambermaid in the other. A day spent in the canyons around Los Angeles proves there's a big difference between these cars. First, though, let's discuss their similarities. The S6 and the S7 get the same design overhaul we detailed in our piece on the 2016 Audi A6, namely the edge work done on the grille, bumpers, headlights, and taillights. Additionally, they get Audi's new MMI system – the brand's next step in infotainment. A day spent in the canyons proves there's a big difference between these cars. Changes exclusive to these S models include flat-bottomed steering wheels with model badges at the base of the center spoke, and aluminum-finish shift paddles. The pedals and footrest get the aluminum look as well. There's also a new shift lever, and a revised design for the Quattro badge. New seat and surface treatments join the options list, such as Beaufort Walnut inlays and Valcona leather seats in Cedar Brown. The S7 has a new Arras Red interior option as part of its design selection palette, but the striking addition there is the carbon fiber inlay it comes with, which is interwoven with a red thread. You lean in really, really close and see that scarlet yarn, and the cockpit immediately feels more special. It's the kind of beautiful subtlety you expect from Audi, and the result is a scrumptious cabin. The twin-turbo, 4.0-liter V8 gets 30 more horses, topping out at 450 horsepower. Torque remains the same at 406-pound-feet, but fuel economy increases ever so slightly to 18 miles per gallon in the city, 27 mpg highway, and 21 mpg combined. The S6 makes a meal of curves, but it does give away a hint of the effort. It seems that a fair number of buyers wanted S vehicles without the whole suite of go-fast bits; they liked having the "S" on their chests, they didn't need all of the superpowers. Thus, Audi took the Quattro sport differential and dynamic steering off the standard menu, and bundled it with the sport exhaust to create the now-optional Sport Package.

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.
