Recharge Wrap-up: Schaeffler 48V mild hybrid Audi TT, Georgia Power charging stations

Schaeffler will test a 48-volt mild hybrid system in the Audi TT. A lithium-ion battery powers an electrified rear axle, which supplements the power provided to the front wheels from the internal combustion engine. The system includes a belt-driven starter generator also running on 48 volts. The car has driver-selected Sport and Eco modes, the latter of which maximizes all-electric driving at low speeds for increased fuel economy. The rear axle can also support the front when more traction is needed. Sport mode wrings out every bit of performance from both the internal combustion and electric motors, with torque vectoring between the rear wheels offering extra stability. Read more at Green Car Congress, or in the press release from Schaeffler. A man has built a near-life-size replica of a Tesla Supercharger out of Legos. Robert Turner's ode to the charging station stands at 42.5 inches tall (which looks impressive standing next to a real Model S), and took over three months to build. Turner showcased his Lego Supercharger at the Brickworld Chicago Lego convention, and he goes into more detail about the painstaking process of forming his creation out of tiny plastic bricks in a video interview. See the Lego Supercharger and read more at The Brothers Brick. Georgia Power is opening 11 new EV charging stations around the state. The charging islands – which are located at various Georgia Power locations – offer DC fast charging with CHADeMo/SAE Combo plugs as well as Level 2 208/240-volt chargers. Customers can pay with either a Georgia Power or ChargePoint card. These first chargers are part of a larger plan by the utility to roll out 61 charging islands throughout Georgia by the end of 2016. See a list of locations and learn more in the press release below. Georgia Power opens 11 new EV charging islands First phase of statewide public charging infrastructure completed ATLANTA, Sept. 30, 2015 /PRNewswire/ -- Georgia Power announced today that the company will open 11 new electric vehicle (EV) charging islands to the public on October 1. The new charging islands, located at Georgia Power properties across the state, mark the completion of the first phase of planned charging infrastructure being developed by the company which will include approximately 61 community charging islands for public use statewide by the end of 2016.

Audi updates the RS3 hatch to sedan specs, but we still aren't getting it

As great as the upcoming Audi RS3 sedan looks and sounds, we're still a bit jealous of the Europeans and others who get the five-door Sportback version. And now even more so, because for 2018 the RS3 Sportback is being updated to match the specs of the RS3 sedan that debuted last fall at the Paris Motor Show. We'll see the revised extra-hot hatch next month in Geneva. Even though we haven't had a chance to get behind the wheel of either model, the raw numbers alone get us excited. An updated Quattro all-wheel-drive system, a 400-horsepower turbocharged inline five-cylinder engine (up from 362), and a seven-speed dual-clutch transmission will send the 2018 RS3 hatch from 0 to 60 mph in 4.1 seconds. That puts it in Porsche 911 and Chevrolet Corvette territory. Other improvements include a wider track to fit wider rubber, a lowered and stiffened suspension, and a larger set of brakes. Carbon-ceramic front rotors will again be available, like they are on the sedan. Inside, the RS3 comes with a boost pressure indicator, an oil thermometer, and a lap timer. Audi's Virtual Cockpit fully digital instrument panel is available as an option, and one we highly recommend. Aside from all of the performance and tech upgrades, the RS3 has a number of changes to the interior and exterior design. Black Nappa leather sport seats are standard, with special contoured RS sport seats available as an option. Lighting elements have been updated to match those of the restyled A3 and S3, the front fascia has been sharpened, with larger intakes on the bottom corners of the bumpers, a slightly more aggressive front splitter, and the Quattro logo emblazoned on the bottom of the grill. Out back, the car gets two large exhaust tips compared to the S3's four outlets. The overall design is typical Audi: handsome, but conservative. The RS3 sedan goes on sale in Europe in April with the Sportback following soon after. We'll have to make do with the sedan version, which is expected to arrive here next year. The only Sportback model Audi offers here from the A3 family is the plug-in e-tron model, and we don't expect that to change any time soon. But we can dream. Related Video:

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.
