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.

1956 DKW Audi electric van beautifully restored

These days, electric vehicles that make commercial deliveries aren't entirely rare. UPS has a small fleet in California, and at least 5,000 Renault Kangoo Z.E. models are in use by France's national postal service. But the history of this concept is much older. In fact, one of the companies represented by Audi's four rings had an example about 60 years ago. Audi Tradition just completed a full restoration of this blue 1956 DKW Elektro-Wagen to add to the company's collection of historic vehicles. It's quite a rare find because only two are still known to exist. Audi estimates that DKW built about 100 of these electric vans between 1955 and 1962, and they were primarily sold to energy companies, public utilities and battery makers. To create the EV model, DKW took its normal Schnellaster delivery van and replaced the model's two-stroke engine with an electric drivetrain. The vans weren't exactly speedy, though. The motor produced about 6.7 horsepower and lead-acid batteries offered 200 amp hours of power running at 80 volts. It gave the Elektro-Wagen a claimed range of about 50 miles and a 25 mile-per-hour top speed. Following the restoration, Audi took van to the island of Wangerooge in the North Sea to show it off. The location is perfect, too, because vehicles with internal combustion engines are banned on the island. If you can read German, feel free to find out more in the press release below. „DKW Elektro-Wagen" zu Audi heimgekehrt Einen von zwei verbliebenen DKW Elektro Schnellaster restauriert Klein-Bus einst auf der Nordseeinsel Wangerooge im Einsatz Audi Tradition prasentiert einen aussergewohnlichen Neuzugang in seiner historischen Sammlung: einen „DKW Elektro-Wagen" von 1956. Zwischen 1955 und 1962 produzierte die Auto Union GmbH in Ingolstadt DKW Schnellaster – etwa 100 davon als Elektro-Automobile, die das Unternehmen vor allem an Energieunternehmen, Stadtwerke oder Batteriehersteller verkaufte. Bei dem nun nach aufwandiger Restauration „heimgekehrten" Elektro-Schnellaster handelt es sich um ein besonderes Exponat: Der DKW fuhr auf der Nordseeinsel Wangerooge, wo Automobile mit Verbrennungsmotoren verboten sind. Normalerweise war der DKW Schnellaster mit einem Zweitaktmotor ausgestattet - der „Elektro-Wagen" hingegen mit einem funf Kilowatt (kw) leistenden Reihenschluss-Motor. Die seitlich in zwei Kasten gelagerten Bleibatterien hatten eine Nennspannung von 80 Volt und eine Kapazitat von 200 Amperestunden (AH).

Audi A5 and S5 Sportbacks look slinky for the Paris Motor Show

Following closely on the heels of the updated Audi A5 and S5 refresh, the German automaker introduced the 2017 Audi A5 and S5 Sportback. The vehicles are set for an official debut at the Paris Motor Show next month and share many of the same exterior touches as the regular coupes. Audi's sportback models are not sold in the US. A spokesman from Audi told Autoblog that the automaker is still deciding whether to bring the vehicles to the US. The A5 and S5 Sportback are aimed at drivers that want the same feel as the coupe with the added functionality of a hatchback – think wagon meets sedan. Besides the extra set of doors, there's very little that differentiates the sportback models from the coupes. The new models are built upon Volkswagen's MLB platform, which makes the car roughly 190 pounds lighter than the outgoing model. European customers will be able to choose between two TFSI and three TDI engines for the A5 Sportback. The engines range from a 2.0-liter inline-four that makes 190 horsepower to a 3.0-liter turbocharged diesel V6 putting out 286 hp. The engines can be paired to a six-speed manual transmission, seven-speed S tronic dual-clutch gearbox or an eight-speed tiptronic unit. Front-wheel drive is standard, with all-wheel drive as an available option on two variants. AWD comes standard when opting for the more powerful engines. The vehicles will also feature Audi's new Quattro Ultra all-wheel-drive system that can disconnect the rear wheels to be more fuel efficient. The S5 Sportback is the one enthusiasts will enjoy as it packs a turbocharged 3.0-liter V6 that's good for 354 hp and 369 pound-feet of torque. Audi claims the S5 Sportback, even with the addition of its new doors, will be able to get to 62 mph in 4.7 seconds, which is the same time as its two-door counterpart. In addition to the diesel and gasoline-powered vehicles, the A5 Sportback g-tron will be offered for drivers looking for flexible fuel choices. The g-tron model is powered by a 170-horsepower, 2.0-liter turbocharged-inline-four that can run on Audi e-gas, natural gas or regular gasoline. The exterior design is nearly identical to that of the coupes with Audi's new single frame grille and muscular front end. The rear incorporates a fastback-like design, similar to the one found on the A7, which helps soften the vehicle out – all sport in the front and luxury in the rear.
