24 Hours of Le Mans an on-and-off love affair

There was little usual about this year's 24 Hours of Le Mans - intermittent rain in the weeks before the race meant cars didn't get on track as much as they wanted, and intermittent rain during the race meant cars went off track a lot more than they wanted. The race started with a wet track, and one of the records broken because of the random downpours was the number of times the safety car led the field - 11 times this year - although the record of two hours and 53 minutes of lapping behind the safety car, set in 2011, was not eclipsed.
None of that served to dampen the action. With little more than an hour left in the race there were cars still only a few seconds apart fighting for position, leads still changing because of pit stops and everyone drafting anyone they could.
Things didn't go the usual way up front, either - well, not exactly...

Audi's diesel-electric supercar is codenamed 'Scorpion'

Speculation continues as to the final nature of the diesel-hybrid Audi supercar said to arrive in 2016 or 2017. A previous report in Automobile had the halo coupe, based closely on the R18 etron quattro endurance racer, codenamed R20 and pegged to look like a Le Mans winner for the street with around 700 horsepower and 737 pound-feet of torque from a twin-turbo V6. Now Car and Driver has updated the gossip with a report that the car is internally called "Scorpion," and it will be even closer to the R18 than supposed.
CD says the heart of the car will use the R18 etron quattro's carbon fiber tub and its engine will be "taken directly" from the race car. That means a 3.7-liter V6 with a single turbo that, in ACO-spec restricted form, outputs 500 hp and 625 lb-ft - CD suspects production output could get to 600 hp - and drives the rear wheels, aided by hybrid motors driving the front wheels. And remember, at Le Mans the R18's hybrid motors can't kick in until they're above a certain speed in order to prevent Audi from getting an advantage coming out of slow corners. A street car wouldn't face that restriction.
The Scorpion would be a fulsome and undiluted example of the technologies Audi has created during its return to sports car racing. Its exterior design hasn't been finalized, with CD citing either the convoluted concept of "a retro take on the future of racing" or packaging that would adhere to the R18's looks. To make sure it is properly appreciated and sells well, production could be limited to the same 333 units as the R8 GT and A1 Quattro.

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.
