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.

New Audi R8 Spyder V10 Plus is a topless brute

If the "normal" 540-horsepower R8 Spyder isn't doing it for you, the wait is over. Audi has upped its convertible, mid-engined Huracan sibling to Plus spec, which means the FSI V10 gets a whopping 70-horsepower bump, all the way up to 610. Plus, like its lowlier sibling, you get a power folding soft top that goes up or down at up to 31 mph. But wait, there's more! The normal R8 Spyder can hit 60 miles per hour in just 3.5 seconds, according to the manufacturer, while the new one will hit 62 mph in 3.3 seconds. (Since the first specs we have are for the European version, we get 0-100 km times rather than 0-60 mph times. It's clear the V10 Plus is notably quicker.) No matter where you buy one, each V10 Plus will rev out to 8,700 rpm. Top speed increases slightly, to 203.8 mph – much faster than you'd want to go with the top down, surely. The rest of the powertrain is standard R8. There's a seven-speed S-tronic dual-clutch gearbox, the only transmission available, and Quattro all-wheel drive standard. Like the standard R8, it can send up to 100 percent of its power to either axle in extreme situations, and there's a rear differential locker for added traction. While a variable-assist steering rack is an option, the standard steering box is an electromechanical unit. Inside and out, there's a lot of exotic stuff. Optional Audi laser headlights and standard Audi virtual cockpit tick the box for Euro technophiles, while diehard Audi Sport enthusiasts will appreciate the carbon fiber diffuser that adds up to 220 pounds of downforce to the package. Speaking of pounds, that top weighs 97 pounds, but the total package weighs 55 less than the regular R8 Spyder. That weight savings is due to lightweight bucket seats, carbon ceramic brakes (15 inches up front, 14 in the back), and lighter alloy wheels. The cars will be delivered in Europe in late summer. We'll know more about US-market cars soon, surely.

Don't hold your breath for an Audi RS8

There was a time not so long ago when Quattro GmbH produced essentially one model at a time. But that time is behind us. These days it's expanding into a full-fledged performance division to rival Mercedes-AMG and BMW's M department. Quattro GmbH is currently building the Audi RS4 Avant, RS5 coupe and cabrio, RS6 Avant, RS7, RS Q3 and the TT RS coupe and roadster - not to mention the R8. And while it's showing no signs of slowing down, but the latest intel from across the pond suggests we shouldn't count on an RS version of Audi's flagship sedan.
This according to Car and Driver, which spoke to Stephan Reil, the chief engineer at Quattro GmbH. Reil says Audi works on a teutonically rigid performance formula: an RS model has to have 20 to 25 percent more power than the existing S version. Considering that the existing S8 makes 512 horsepower and the RS7 a solid 553, we're not sure Audi really needs anything more powerful. But by Reil's calculations, the RS8 would need to pack between 630 and 655 hp, which would put it well ahead of rivals like the 550-hp Jaguar XJR, the 540-hp BMW Alpina B7, the 523-hp Maserati Quattroporte and even the new 577-hp Mercedes-Benz S63 AMG - and in league only with the even more powerful S65 AMG, which in its outgoing form produced 630 hp.
The question then comes down to whether there are enough customers lining up for the S65 that Audi would want to poach away from Mercedes. Or perhaps more pertinently, whether it might end up just taking customers from the new Bentley Flying Spur, which is already offering 616 horsepower in an even more prestigious, if less performance-focused package. Either way you look at it, Audi is apparently steering clear.
