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.

Weekly Recap: Audi pulls back the curtain on its future

The E-Tron Quattro concept is the future of Audi. It embodies all of the traits that will make the brand – and electric-powered luxury vehicles – more relevant into the 2020s. Here's why: The E-Tron Quattro concept, which will debut next month at the Frankfurt Motor Show, is a large sport utility vehicle that promises a range of 311 miles. It's an all-electric daily driver that fits the needs of most Americans. In production – which Audi says starts in 2018 – this vehicle will seat five and likely be called the Q6. You can take your family from Boston to Philadelphia without recharging. That's mainstream. We're moving away from the industry's "science experiment" era (as General Motors product chief Mark Reuss once described the appearance of the first gen-Chevy Volt) to a period where electric vehicles are plausible and practical for many US buyers. The 2018 Q6's only holdup for the masses will be price. But if you can afford an Audi SUV, you'll be able to buy an all-electric version. The E-Tron concept uses Volkswagen Group's second-generation modular longitudinal platform. The lithium-ion battery is located between the axles and below the cabin. Urquhart says the production model will feature the automaker's latest battery technology developed with LG Chem and Samsung. IHS Automotive projects the Q6 will sell more than 40,000 units annually by the end of the decade. "The E-Tron Quattro is a precursor for what will be an exciting and landmark production model for Audi and will position the brand at the forefront of the premium EV market," IHS analyst Tim Urquhart wrote in a commentary. It's the Tesla-zation of America. It's the Tesla-zation of America. The Q6 will be a Model X fighter, and expect other automakers to follow suit, particularly in the luxury sector with SUVs and other large vehicles. They offer more space for the battery packs, and development costs can be recovered easier. "Premium brands have an inbuilt advantage in terms of introducing [electric] powertrains over more mainstream automotive brands," Urquhart wrote. OTHER NEWS & NOTES Analyst says Tesla stock could be worth $465 a share Morgan Stanley analyst Adam Jonas sent shockwaves through the industry when he said Tesla stock has the potential to reach a whopping $465 a share. That's a leap from its $230.77 price at Friday's market close.

Audi is working on a suspension that gets power from bumpy roads

Regenerative brakes aren't new. They're on virtually every hybrid and EV, and they're even starting to pop up on traditional gas-powered cars, like with the i-ELOOP-equipped Mazda6. But even with these systems, cars can get more efficient, and Audi thinks it found yet another source of wasted energy. The source? The suspension. The idea is to turn the kinetic energy that goes into the dampers into usable energy instead of as waste heat. Audi isn't the first auto company to come up with regenerative suspension – nearly three years ago, ZF introduced its GenShock technology, which used a valve attached to traditional, oil-filled hydraulic shocks to recapture kinetic energy from movement caused by bumps in the road. Audi's prototype technology, which it calls eROT, replaces traditional dampers with horizontally oriented electromechanical rotary dampers. eROT is apparently short for electromechanical rotary damper. Neat. In testing, eROT recovered an average of 100 to 150 watts on a typical German road, three watts from a fresh piece of pavement, and 613 watts on a rough stretch of tarmac (wattage is calculated as power over time, so this is actually the rate at which the system harvests energy). The dampers channel that energy to a tiny, 0.5-kWh, 48-volt battery. The prototype is claimed to cut CO2 emissions by three grams per kilometer (4.8 grams per mile), while the company believes a future production version could save up to 0.7 liters of fuel per 100 kilometers of driving. Converting the savings to American miles per gallon isn't easy, so we'll use a practical example. In the US, the Q7's supercharged 3.0-liter V6 returns a combined rating of 21 miles per gallon, which works out to 11.2 liters per 100 kilometers. Apply eROT's 0.7L/100km savings, and the Q7's economy would improve to 10.5L/100km, or 22.4 mpg, a 1.4-mpg improvement. That's not huge, but because math, 0.7L/100km is more dramatic on a more fuel efficient vehicle – taking an A3's 27-mpg combined rating and adding eROT would drive efficiency up 2.4 mpg, for example. There are a few other big benefits beyond fuel and emissions savings – Audi claims eROT provides a more comfortable ride than traditional active suspensions, because engineers can tune the compression and rebound strokes independently of each other. Beyond that, the horizontally oriented rear suspension geometry means more cargo space, since the dampers don't poke up into the cabin like they normally do.
