Daily Driver: 2015 Audi S7

Daily Driver videos are micro-reviews of vehicles in the Autoblog press fleet, featuring impressions from the staffers that drive them every day. Today's Daily Driver features the 2015 Audi S7, reviewed by Seyth Miersma. You can watch the video above or read a transcript below. Watch more Autoblog videos at /videos. VIDEO TRANSCRIPT [00:00:00] Hi, all. This is Seyth with Autoblog. I'm here driving the 2015 Audi S7. I'm caught in a kind of annoying, normal, end-of-the-work-day suburban traffic right now, but even that helps to illustrate the point that I'm trying to make about the S7, is that it really is one of the best all-around grand touring cars that you can buy. A really, really good grand tourer has to do three things. [00:00:30] One, it has to look amazing. It has to feel really special inside and out. The second part is that it's got to be a great long-range cruiser. It needs to be powerful on the highway, be able to be very comfortable and quiet if you're taking it long distances, kind of like your typically Autobahn car. Three, and I think this is really difficult with the second one that I mentioned, I think that grand tourers have to be really great at driving like sports cars. [00:01:00] You're going along and you're touring on the highway and you know that a really great road is coming up. The car should be able to get off on that road and handle like something much lighter and still have that great cruising character. That's one of the reasons why I've always liked the entire Audi A7 line, but especially this S7 because the A7 itself in all of its guises is really a pretty great cruiser and a really practical all-around car with the space in the hatch [00:01:30] and reasonable room in the back seats. The S7 with the turbocharged 4.0-liter V8 making 420 horsepower and 406 pound-feet of torque really amps up the sportiness. Now don't get me wrong, the S7 is far from a sports car. It's not very light. It's got a long wheelbase. It is nimble, especially with Quattro, but it doesn't feel especially nimble. It doesn't want to change directions super quickly. It splits the difference between the two. That being said, [00:02:00] when you get up to some of your favorite roads, it doesn't disappointment you either because of all the power and grip and some pretty decent sporting character available. Of course one thing that you do lack in a big GT like this S7 vs.

Audi traffic light recognition could save 240 million gallons of fuel [UPDATE]

Any hypermiler will tell you that the way you drive your car has a huge impact on how much energy it uses. But these greenfoot drivers haven't had a car that's smart enough to tell them about the inner lives of traffic lights. That's what a prototype system in an Audi A6 Saloon that the German automaker recently tested in Las Vegas can do. Since the car can communicate with local traffic signals and is able to predict when lights will change, the car can help reduce CO2 emissions by up to 15 percent. Further, Audi says that the system could save some 238 million gallons of fuel (900 million liters), if deployed across Germany. We can only imagine what hypermilers could do with this. We got to drive the Audi Online traffic light information system prototype in January, but we focused more on how the system worked rather than the green aspect. Now that Audi has had a bit more time to crunch the numbers, it has released fuel economy information for the connected car. The key points for the eco-side of things are that the driver is told in the dashboard how fast/slow to go to hit the next green light. This can help prevent unnecessary speeding and or encourage drivers to go a bit faster in order to hit the green, thus preventing idling and wasted time. The system is too smart to let you idle for long. Except that Audi Online is too smart to let you idle for long. The Audi connect system can calculate how much longer the light will be red and can access the car's start-stop capabilities and will fire up the engine "five seconds before the green phase." That seems like an awful long time in a world where competitors have figured out ways to restart an engine in 0.35 seconds. We've asked Audi for an explanation on why this buffer is so lengthy, and will let you know what the reasoning is when we hear back. Despite the trials in the A6, Audi says the Audi Online traffic system could be integrated into any Audi model, "subject to the necessary government legislation." Aside from the Sin City tests, Audi is running trials of the connected car in Verona, Italy and Berlin, Germany. If you'd like to test it out yourself some day, take heart from this line in the press release, available below: "A market launch is currently the subject of intense analysis in the United States." *UPDATE: Audi's Mark Dahncke told AutoblogGreen that the five second window is meant, "To alert the driver that the light is about to turn green.

Audi SQ7 TDI packs 48V electric compressor, 664 lb-ft

Take a look at the new Audi SQ7 TDI. It's the first time Audi has done an S performance version of its flagship sport-ute, and packs under the hood a 4.0-liter V8 turbo diesel engine mated to an eight-speed automatic and all-wheel drive. It produces a potent 435 horsepower, and an absolutely bonkers 664 pound-feet of torque. The Audi SQ7 TDI produces a massive 664 lb-ft of torque. Impressive as it is, though, that doesn't even tell the full story. That's enough to make us forget it wasn't there in Geneva. It's also more torque than just about anything the Volkswagen Group makes – short of the Bentley Mulsanne Speed and the new Bugatti Chiron. Not even the Lamborghini Aventador SV or Bentley Continental GT Speed can touch that torque figure. Nor can competition like the Porsche Cayenne S Diesel (with its 385 hp and 627 lb-ft) or the BMW X5 M50d (381 hp and 546 lb-ft). It may not surpass the old twelve-cylinder Q7 6.0 TDI (with its 493 hp and 738 lb-ft), but still trounces the VW Touareg V10 TDI (309 hp and 553 lb-ft) – which was strong enough to tow a jet airplane, while the new SQ7 is fast enough to out-drag one (as you can see from the video below). Impressive as it is, though, that headline-grabbing torque figure doesn't tell the full story. To get there, Audi employed two conventional, sequential turbochargers and a third compressor that – in an industry first that's been a long time coming – is powered electrically. The engineers in Ingolstadt installed a beefier 48-volt electric subsystem to power the electric compressor (among other systems) and its latest valvetrain tech for the first time in a diesel. The result, Audi says, is a lack of any perceptible turbo lag – and a 0-62 time quoted at 4.8 seconds, en route to the typical electronically limited top speed of 155 miles per hour. As if that weren't enough, Audi also equipped the SQ7 TDI with an optional suspension package that coordinates the activities of three systems. There's a differential, a four-wheel steering system, and a clever electromechanical roll stabilization system that employs an electric motor (made possible once again by that 48-volt system) and a three-stage planetary gearbox to keep it all level and improve ride quality over rough surfaces. The sum total is an impressive technological tour de force on Audi's part, but one that we may just have to admire from afar.
