Audi Q7 plug-in hybrid spied, Porsche powertrain possible

It's no secret that a new Audi Q7 is on the way. The replacement for the aging, three-row luxury CUV has already been spotted once, in December of 2013. Now, though, we have images of the second-generation model lapping Germany's Nürburgring Nordschleife, and it just happens to be showing a feature we reported on at the end of July - a plug-in-hybrid powertrain.
Given away by its high-voltage stickers on the window and a spare door to hide the charger - note how both the driver and passenger sides sport an access point - our spies snapped a series of photos, and put forth the compelling idea that the new Q7 would use the PHV system from the Porsche Cayenne S E-Hybrid.
If that's the case, that should mean at least 320 horsepower from a 3.0-liter, supercharged V6, while an electric motor chips in a further 95 ponies for a total system output of 416 hp.

Audi TT Quattro Sport Concept takes the next-gen to the extreme

There's little doubt that the new Audi TTS and its 310-horsepower, 2.0-liter, turbocharged four-cylinder will be very quick when released to the general public. As a means of reminding us that Audi can do much more with the little TT, though, the German manufacturer has presented this, the TT Quattro Sport Concept, alongside its litter of new sports cars.
Complete with a 420-horsepower, 2.0-liter, turbocharged engine - yes, it really puts out 210 horsepower per liter - the TT Quattro Sport can snap to 62 miles per hour in just 3.7 seconds. 331 pound-feet of torque is also on offer, meaning this one-off TT outguns the TTS by 110 horsepower and 51 pound-feet of torque.
An S-Tronic transmission shuffles the power about, while the car itself rides on a lowered and stiffened suspension. 20-inch alloys are featured with centrally locking, racing-style hubs. Those racy wheels are housed in wells that have had their arches stretched an additional 1.18 inches, which, along with the lowered suspension, contribute to the TT's aggressive looks.

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.
