Recharge Wrap-up: Smart metals, OTA updates, Rolls-Royce LNG ship

"Smart" metals could help engines reduce emissions and invigorate US business. Metallurgist and University of Wisconsin – Milwaukee professor Pradeep Rohatgi combines known metal alloys with materials like ceramics, nanoparticles, and recycled waste to produce strong, lightweight composites with self-lubricating properties that help internal combustion engines run more efficiently. Rohatgi hopes his startup, Intelligent Composites, and its products can help US foundries compete with production outsourced overseas. See the video above, and read more at Phys.org. Almost 203 million cars will be capable of over-the-air (OTA) updates by 2022, according to ABI research. While Tesla has the OTA firmware updates nailed down, other automakers will focus on software update capability. This will take the place of dealer-installed updates and - like Chrysler did after the Jeep hacking incident - updates sent to owners via USB drives. OTA updates will enhance vehicle security and reduce recall rates. Read more at Green Car Congress. European bus manufacturers have agreed upon a standardized charging interface for their electric buses. Irizar, Solaris, VDL and Volvo will use pantograph charging for "opportunity charging" and CCS plugs as the base for overnight charging and network communication. The manufacturers hope other bus makers and charging providers to join them in cooperation over standardized charging. Read more at Green Car Congress. The second Audi Autonomous Driving Cup will take place from March 22 to 24, 2016 at the automaker's Museum Mobile in Ingolstadt, Germany. The competition involves eight university teams implementing basic Audi software in 1:8 scale electric Audi Q5 models, and putting them through the paces of simulated real-world driving situations. The teams develop software architecture to use the suite of sensor to have the cars drive, park, maneuver in traffic and perform emergency braking autonomously. Teams also perform a freestyle event where they put the car through an additional task of their choosing. The winning team gets ˆ10,000, with smaller prizes for second and third place. The competition also gives the students the opportunity to showcase their skills in front of a potential employer. Read more at Green Car Congress. Rolls-Royce will provide the Liquefied Natural Gas (LNG) propulsion for an NSK cargo ship carrying fish food. The ship will deliver 2,700 metric tons of fish food to fish farms along the Norwegian coast.

Audi RS3 sedan spied testing at the Nurburgring

Although American enthusiasts often miss out on foreign forbidden fruit, we've known for a while that the Audi RS3 will probably make it to the United States in 2017. While there's been no official word, Audi of America CEO Scott Keogh has made it clear he wants to bring the car over. Audi already sells the handsome RS3 Sportback in Europe, but since European hot hatches don't tend to fly here it will most likely come only as a sedan. Now we have spy shots to drool over. View 7 Photos These gallery above shows the 2016 RS3 Sportback that sits at the top of the range in Europe. The RS3's turbocharged five-cylinder engine sends power through Audi's quattro all-wheel drive system, propelling the car to 62 mph in just over four seconds. We can only make an educated guess as to what will power the RS3 sedan. Quattro all-wheel drive is a given, as is turbocharging. The European RS3 Sportback comes with a seven-speed dual-clutch that will probably make it to the US. In that car, the transmission is fed by a 2.5-liter turbocharged inline five-cylinder engine making 362 horsepower and 343 pound-feet of torque. Rumors suggest that Audi will make up for lost time by giving us the 400-hp inline-five that powers the new TT RS. These spy photos show a black RS3 sedan ripping around the Nurburgring, partially covered in camouflage. Through the camo we can see all of the basic hallmarks of Audi's RS line: cues like larger wheels, brakes, and a spoiler. The front has a hexagonal pattern in the grille that's typical of RS models, while the air intakes are larger and the chin spoiler looks to sit lower than the standard car's. From the side we can see different skirts and fixed brake calipers. Around back two large exhaust pipes replace those of the standard car, which may be the biggest indication that the vehicle is in fact the RS3. Models like the S3 and S4 have quad exhaust tips, while RS models feature two large exits like the ones on the 2016 RS3 Sportback. For 2017, Audi has made some changes to the A3 line, but we haven't heard or seen anything official from Audi regarding the 2017 RS3, be it Sportback or sedan. With the A3 and S3, the interior benefits from the company's fantastic virtual cockpit digital gauge cluster. The company also added some driver assistance features and refreshed the car visually with new front and rear facias.

Audi testing long-tail version of R18 e-tron quattro for Le Mans

Race teams are always looking for ways to shave hundredths of seconds of their lap times. Case in point: Audi is making some slight changes to its prototype racecar to make it ever so much more slippery as it cuts through the air.
Debuting at the second round of the FIA World Endurance Championship at Spa on May 4, Audi will be testing a long-tail version of its R18 E-tron Quattro racecar. As its name suggests, the long-tail car gets a lengthened rear section with the goal of improving aerodynamics. The long-tail will be run alongside the standard version of the racecar as a testbed for possible changes that might be in store, heading into the 24 Hours of Le Mans.
Audi did not say how many inches were added to the racecar, but as you can see in the image above, "long-tail" definitely doesn't take on the same meaning of classic long-tail cars of the past such as the Porsche 917. More information about the car, Audi's team and even some info about the track itself can be found below.
