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.

Justin Bell laps Willow Springs... in the dark... using only night vision

Night vision has made its way into quite a few luxury cars as a night-driving safety feature, but eBay Motors wanted to see if the technology could be used to actually drive the car. Former racer and World's Faster Car Show host Justin Bell grabbed the keys to an Audi A7 and headed to Willow Springs Raceway to find out.
As if driving in the dark of the desert night wasn't hard enough, the car's windshield and side windows were blacked out, so Bell's driving relied completely on the three-inch night vision display located in the gauge cluster. In addition to navigating the track, his producers also threw in a few surprises for Bell on the track. We don't want to spoil too much for you, but based on the speeds exhibited in the video, we don't think 24-hour endurance races will be adding this tech any time soon; that being said, he probably drove the car faster and better than we could have.
Scroll down to watch how Bell does lapping the track using only the car's night vision.

Audi-only rental car company expands

With the lines and occasional hassle, getting a rental car after a long flight can be daunting, even if you already have a reservation. Now, a company called Silvercar is trying to inject some luxury and modern, high-tech features into the process to make it less of a chore. The business recently expanded to O'Hare International Airport to offer visitors to Chicago a fleet exclusively comprised of silver Audi A4s. Silvercar is based in Austin, TX, and is being run by Luke Schneider, a former chief technology officer at ZipCar. He told Crain's Chicago Business that the rental industry "hasn't innovated in 30 to 40 years." Silvercar's big innovation is in the booking process. Like ordering practically anything today, it's all done through a smartphone app. Customers then scan a QR code on the Audi's windshield to get going. At the end of the rental, the bill is emailed to you. Prices start around $59 a day on weekends and $89 during the week, according to Crain's. Because they're all A4s with GPS and Wi-Fi, everyone gets the same car. In the world of ridesharing companies like Uber and Lyft, rental cars might seem passe, but according to Crain's, the rental market at O'Hare alone amounts to over $300 million a year. Silvercar's location there isn't at the actual airport, though. Instead, a shuttle picks up customers to take them to the company's site nearby. The business is working on a national rollout to 10 airports by the end of June, including major locations like LAX and Denver.
