1,682 miles in a 2014 Audi A8 L TDI - Part 1

We're going to skip the joke - because this isn't one - and get straight to the punchline: If the forthcoming 2014 Mercedes-Benz S-Class looks like it will lead the segment in interiors, the 3.0-liter turbodiesel in the 2014 Audi A8 L TDI takes the head of the table when it comes to engines.
After joining Audi for the 12 Hours of Sebring, we stood in the parking lot of The Inn On The Lakes on Sunday morning, our thousand-yard stare interrupted by the Citgo gas station across the street. We had one key, three bags, one white A8 L TDI, something like 17 gallons of diesel in the tank and one week to burn through it. For the purposes of a Quick Spin, we could have simply traipsed around the central Florida outback, all citrus, dusty scrubland and diners lifted from Cronenberg films, made short work of measuring the refinement and potential rarefaction of the oil burner under the hood and made our way back to the Orlando airport.
But dear readers, where would the adventure be in that?

Weekly Recap: The divergent paths of Tesla and Fisker

There's no doubt that Tesla is downshifting while Fisker has been grinding its gears. But it wasn't always that way.
In the wake of Tesla's recent success, it's easy to forget that there were once two California electric carmakers with bright futures.

Audi RS7 prototype is world's sportiest self-driving car [w/video]

Audi may not be the only automaker out there toying with self-driving automobile technology, but it is arguably the fastest of them. A few years back, it raced unleashed a driverless TTS on the Bonneville Salt Flats, then sent it up Pikes Peak and around Thunderhill. But now it's taking things a step further with the vehicle you see here.
This RS7 Sportback has been fitted with steering, brakes, throttle and transmission hooked up to a computer system that combines GPS, high-frequency radio signals and 3D imaging camera to drive the vehicle autonomously not just in slow-paced, stop-and-go traffic, but around the track at the same pace a professional racing driver would push it: full throttle on the straights, full braking before the corner and 1.1-g of cornering force.
As promised, Audi plans to unleash the self-driving RS7 - which it calls "the sportiest piloted driving car in the world" - at Hockenheim next weekend prior to the DTM season finale, where it is anticipated to pull a 2:10 lap time. The next stage will be to set it lose on the Nürburgring Nordschleife, all 154 turns and 13 miles of it, which ought to pose a heck of a challenge to the engineers from Ingolstadt. In the meantime you can scope it out in the high-res image gallery above and the second teaser video below.
