Stanford goes from Pikes Peak to Thunderhill with autonomous Audi TTS

In the years since Stanford University engineers successfully programmed an Audi TTS to autonomously ascend Pikes Peak, the technology behind driverless cars has progressed leaps and bounds. Back then the Audi needed 27 minutes to make it up the 12.42-mile course – about 10 minutes slower than a human driver. These days, further improvements allow the vehicle to lap a track faster than a human. The researchers recently took their autonomous TTS named Shelley to the undulating Thunderhill Raceway Park, and let it go on track without anyone inside. The Audi reportedly hit over 120 miles per hour, and according to The Telegraph, the circuit's CEO, who's also an amateur racing driver, took some laps as well and was 0.4 seconds slower than the computer. To make these massive technological advancements, the Stanford engineers have been studying how racers handle a car. They also hooked up drivers' brains to electrodes and found the mind wasn't doing as much cognitively as expected. It instead operated largely on muscle memory. "So by looking at race car drivers we are actually looking at the same mathematical problem that we use for safety on the highways. We've got the point of being fairly comparable to an expert driver in terms of our ability to drive around the track," Professor Chris Gerdes, director of Stanford's Revs Program, said to The Telegraph. With progress coming so rapidly, it seems possible for autonomous racecars to best even elite drivers at some point in the near future. Related Video:

Recharge Wrap-up: Porsche adds third 919 Hybrid for Le Mans, Audi to heat factory with geothermal

Porsche will be running a third 919 Hybrid LMP1 car in the 2015 24 Hours of Le Mans endurance race. The extra Porsche will race in the six-hour May 2 WEC race at Spa-Francorchamps as a lead-up to the legendary 24-hour race on June 13 and 14. Porsche hasn't announced the driver lineup for the third 919 Hybrid, but drivers will remain the same for the other two cars. Including the third car is meant to help further test performance and efficiency as part of development for future hybrid systems. Read more at Green Car Congress. BMW i Ventures is investing in Zendrive, a driving focused data and analytics company. The cooperation of the two companies is meant to help advance safety and efficiency by making the "in-car mobility experience even smoother by optimizing commuting and driving patterns," according to BMW i's Ulrich Quay. The venture capital arm of BMW's i brand also invests in JustPark, Chargepoint, Life360, Chargemaster and MyCityWay, and says it will have more strategic investment announcements in the coming months.

When the facility is finished, Audi expects to source 82,000 megawatt hours of geothermal energy per year from it, or about six percent of its total heating needs. The clean energy helps Audi move "step by step along a path to developing a CO2-neutral production plant," says Audi's Dr. Hubert Waltl. "The mobility of the future must be CO2-neutral – and that applies not only to the use of our vehicles, but also to their production." Read more in the press release below. Supporters have begun a petition drive for the passage of an E15 ordinance in Chicago. Despite pushback from oil companies, the city council is close to passing the "Chicago Clean Air Choice Ordinance," which includes the requirement by retailers to sell the 15-percent ethanol gasoline blend in the city. The ordinance includes an exception for stations selling less than 850,000 gallons of fuel per year. More than 4,000 people have signed the petition so far, with others leaving messages to voice their opinion on the matter in opposition to Big Oil's attempt to block it. Read more at Domestic Fuel.

Audi unveils A3 Sportback G-Tron with bi-fuel power, 808-mile range

By this time next year, the Audi A3 Sportback will be offered with a variety fuel-efficient powertrains ranging from diesel to the all-electric E-Tron, but perhaps the most interesting is the all-new G-Tron model, which uses Audi's innovative carbon-natural compressed natural gas called e-gas. Previously called A3 TCNG, we first heard about this technology last year, but now Audi has confirmed that this low-emission, sustainable-fuel will debut by the end of this year on the A3 Sportback G-Tron.
To create this e-gas, a plant in Werlte, Germany uses electricity to split water into hydrogen and oxygen. As hydrogen fuel cell vehicles become more popular, Audi says that this process could also be used to produce hydrogen fuel, but to create CNG, it mixes the hydrogen with carbon dioxide to create "synthetic methane." Since it is identical to the CNG available today, Audi's e-gas can be shipped and stored using the existing CNG infrastructure. Making the whole process even greener, Audi obtains the CO2 for this process from a nearby biogas plant, which would otherwise be released into the atmosphere.
Differentiated from the regular versions of the A3, the G-Tron features a pair of tanks under the rear cargo floor holding 15.43 pounds of CNG, which can power the car for almost 250 miles. What's more, the A3's conventional gasoline tank is still in place, giving the car an addition 560 miles of range. In total, that means the A3 G-Tron has a driving range of more than 800 miles. To run on both CNG and gas, Audi made changes to the car's 1.4-liter four-cylinder engine (including the turbo, cylinder head and fuel injection system) and catalytic converter.
