2015 Audi A3 Cabriolet

When my 758-mile journey on the A3 TDI Challenge came to an end in Boulevard, CA, Audi had a very nice consolation prize waiting for me: the 2015 A3 Cabriolet you see here. And with miles left to drive before reaching my hotel in Coronado (just outside of San Diego), what better way to celebrate my personal victory of achieving nearly 60 miles per gallon in the TDI than to run the rest of the route in couple of turbocharged A3 droptops? After all, the efficiency part of my drive was done, so it was time to have some fun. The A3 Cabriolet comes to market just as the sun sets on another four-seat convertible from the Volkswagen Group stable: the Eos. That car, often criticized as being too expensive, is technically replaced by the Beetle Convertible as far as VW-badged products go. But for those who still prefer something a bit more upmarket, the A3 Cabriolet will fill the void nicely, and with more style and grace than the Eos ever had. Driving Notes The A3 Cabriolet arrives with a choice of engines. On the base end lives a 1.8-liter turbo-four with 170 horsepower, 200 pound-feet of torque and front-wheel drive, or you can pony up for the 2.0T with 220 hp, 258 lb-ft and standard Quattro all-wheel drive. Regardless of engine, the only transmission available in the A3 Cab is Audi's six-speed S-tronic dual-clutch unit. This is a fine cog-swapper, with quick shifts regardless of chosen powertrain, and steering wheel-mounted paddles that offer plenty of fun from behind the wheel. That said, I found it best to just leave the transmission alone, no matter the engine. The paddles are entertaining, sure, but slick the gear selector into Sport and the A3 will instinctively hold gears through turns and always have you right in the heart of the powerband. The 1.8T's 170 hp and 200 lb-ft are more than adequate for duty in the 3,373-pound A3 Cabriolet. I was never bothered by a lack of power, especially with the engine on boil with the transmission in its sport setting. Hitting 60 miles per hour takes 7.4 seconds, en route to an electronically limited top end of 130 miles per hour. If speed is your thing, though, the 2.0T certainly delivers quite a punch. That same 0-60 sprint takes just 5.9 seconds with the more potent powerplant, and you can really feel the stronger rush of power right off the line, even with the quicker A3's 210-pound weight penalty.

Recharge Wrap-up: Ferrock a carbon-negative cement substitute, Audi makes e-diesel

A cement alternative uses recycled materials and traps CO2 rather than producing it. Invented by David Stone at the University of Arizona, Ferrock uses recycled steel dust and glass to produce a substance stronger than conventional concrete. Cement has a high carbon footprint from the high heat needed to process the limestone. Ferrock needs no such heat, and it actually uses CO2 to harden, making it, as Stone calls it, a carbon-negative material.

Part of the Firmware 6.2 update, Valet Mode allows the owner to disable certain performance features and block personal information when letting someone else drive the car. It limits the car's to speed to 70 miles per hour, and caps output at 80 kW. It can also disable mobile app access, Homelink, Bluetooth and wifi and the "Places" function, which stores addresses for you. The folks at Teslarati did find some shortcomings in the new feature, though. Read more at Teslarati. Audi has produced its first batch of e-diesel made from water and CO2. The fuel is made by reacting hydrogen from the water with CO2 to make long-chain hydrocarbon compounds called "blue crude." That can then be refined similarly to crude oil to make e-diesel, which is a fuel free from sulfur and aromatic hydrocarbons. That e-diesel can be used on its own, or mixed with fossil fuel diesel to power a vehicle. "In developing Audi e-diesel we are promoting another fuel based on CO2 that will allow long-distance mobility with virtually no impact on the climate," says Audi Head of Sustainable Product Development Reiner Mangold.

Fuel of the future: Research facility in Dresden produces first batch of Audi e-diesel - The verdict: Pilot plant produces high-quality diesel fuel - No need for mineral oil: e-diesel made from water, CO2 and green power - Minister Wanka: "Synthetic diesel using CO2 is a huge success" Audi has taken another big step in the development of new, CO2 neutral fuels: A pilot plant in Dresden has started production of the synthetic fuel Audi e diesel. After a commissioning phase of just four months, the research facility in Dresden started producing its first batches of high-quality diesel fuel a few days ago.

Audi TT Ultra Quattro Concept throws lightness at the problem

Audi is celebrating the 2013 Wörthersee Tour with a special concept version of the company's TT. The Audi TT Ultra Quattro concept tips the scales at just 2,449 pounds thanks to some extensive engineering work. The company pulled nearly 95 lbs from the car's body structure and used carbon-fiber reinforced plastics for many of its detachable body components. As a result, the concept weighs in at a full 220 pounds lighter than its production counterpart. Throw in a wicked turbocharged 2.0-liter four-cylinder engine with 310 horsepower and 295 pound-feet of torque, and you get a machine with the power to weight ratio in the supercar realm. 0-60 comes up in 4.2 seconds and top speed is listed at 173 mph.
Inside, the TT Ultra Quattro features plenty of carbon fiber trim, and designers also fitted the seats from the R8 GT to save a little weight. The buckets use CFRP for the seat frames, saving nearly 50 pounds in the process. In a world where automakers seem blind to the negative effect of throwing more heft at a vehicle, we're in love with the Ultra Quattro concept.
