Audi to lap Hockenheim in driverless RS7

An automaker like Audi will always have a number of different research and development projects going at the same time, and some of them might take on very different approaches. At one end, you'll have its racing programs, and at what you'd assume would be the other, self-driving prototypes. But Ingolstadt is preparing to bridge that gap by running an autonomous prototype at racing speed around the famed Hockenheimring.
Set to take place on Sunday, October 19, during the DTM season finale at Hockenheim, the driverless RS7 will motor at speeds up to 150 miles per hour, right up "to its physical limits with millimeter precision."
Audi anticipates that "the world's sportiest piloted driving car" will run a lap time of just over two minutes, at which the RS7 would stand not only to be the fastest driverless car ever to lap the circuit, but also potentially the fastest four-door - if it can beat the 2:02.71 lap time set by a BMW M3 sedan in 2007.

597-hp Audi RS7 Performance coming to US

The Audi RS6 Avant and RS7 Sportback certainly aren't hurting for power. Their 4.0-liter, twin-turbo V8s offer mountains of muscle as tall as the Alps. However, the engineers at the Four Rings are pushing those peaks just even higher for the new Performance versions of the pair. Tweaks to the engine management, bring horsepower up to 597 ponies and 516 lb-ft of torque. Temporary overboost can take the twist to 553 lb-ft, though. This high-performance duo can haul passengers with aplomb by hitting 62 miles per hour in 3.7 seconds – two tenths quicker than a regular RS. Even more impressive, the 12.1-second run to 124 mph also takes 1.4 seconds less than the standard version. Top speed remains the same 155 mph, but the optional Dynamic Package takes off the limiter to let the RS6 reach 174 mph and the RS7 go 189.5 mph. The eight-speed tiptronic remains from the standard RS versions, and it routes power through the Quattro all-wheel drive system with a 40:60 front-rear split. An optional sport differential at the back can also provide some extra assistance. Both Performance models come standard with an adaptive air suspension, but for those willing to spend a little more a stiffer RS sport suspension plus with Dynamic Ride Control is available, as well. The Performance pair launches in Germany at the beginning of November, but there's reason to get excited in the US, too. Audi spokesperson Mark Dahncke confirms to Autoblog that the RS7 Performance is coming here. More details about it should arrive around the Los Angeles Auto Show, he said.

Electric turbos promise big performance and efficiency gains in the near future

An electric turbo system boosts efficiency between 15 and 20 percent, according to Audi.
Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.
