Audi A3 E-Tron is a look at battery-operated things to come

Audi officially unveiled the A3 Sportback E-Tron at the 2013 Geneva Motor Show. While not a production model, the plug-in hybrid gives us a good glimpse at what the German automaker has in store for future products. The five-door gets around thanks to parallel hybrid drivetrain comprised of a turbocharged 1.4-liter four-cylinder engine and a small electric motor integrated into the vehicle's six-speed dual-clutch transmission. While the four-cylinder churns up 150 horsepower and 184 pound-feet of torque, the motor contributes 100 horsepower and 242 lb-ft of twist. All told, the design allows the E-Tron to serve up its full power from just 1,750 rpm.
An 8.8-kWh lithium-ion battery sits under the floor beneath the rear seat, complete with a liquid cooling system designed to keep the pack in its optimum temperature range. The A3 Sportback E-Tron can be charged in as little as 2.5 hours with a 3.6-kW charger, yielding an EV range of up to 31 miles. The machine can also travel using the electric motor, ICE or a combination of the two for a total range of 584 miles. Check out the full press release below.

Evo drives the Audi R18 E-Tron Quattro on track

Audi invited Evo scribe Richard Meaden to the Misano circuit in Italy to drive the Audi R18 E-Tron Quattro - and not just any R18 Quattro, were such a thing possible, but the No. 2 car that took first place at Le Mans this year driven by Marcel Fassler, Andre Lotterer and Benoit Treluyer. Meaden got just four laps in the diesel hybrid racecar - a warm-up, two hot laps and a cool down lap - so this wasn't about testing the R18 E-Tron's limits. In fact, Meaden makes it clear that such a thing isn't even possible for less than a professional driver; when driving at his limits (admittedly in Audi's very expensive car being watched by dozens of Audi engineer eyeballs), the data showed he was using 60 percent of the pedal effort of the professionals. Nevertheless, Meaden does have a lot to say about how the car delivers its massive ability, and with the wide-view shot of the cockpit we also get to see how busy and how intimate an endurance driver's office is.

Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.
