Audi’s Self-Driving Car Hits 150 MPH on an F1 Track

While the RS7’s computer had a detailed digital map of the track and was following an optimized path through it, Audi did not preprogram things like torque or steering.
And that was my point, unlike BMWs famous testrun (with Jeremy Clarkson) where the car was programmed to steer and give gas for every inch of the track, the Audi is actually able to make those decisions on the fly with the information it gets from its sensors.
EDIT: So yes it does use GPS data, but does not rely on it as much as others (including Google).
This obviate the need for deeper GPS depenendence.
You have a 3D track designed with graduated radius turn transitions, smooth topological surfac transitions, and predictable fiction levels. All in a general layout that is suited to safety at speed.
Try running this car at 150mph on glendora mountain road, at night, during a bout of santa-ana cross winds.
I wonder why they didn't use a http://en.wikipedia.org/wiki/Audi_R8 if the goal was racing?
The R8 was based on the Gallardo chassis, whose successor has already appeared. Presumably a Huracan-based R8 successor can't be far behind. Unfortunately RWD sports cars still out handle the Huracan, though by a lesser margin than previously.
The R8 is also at the end of its product life-cycle so they're probably trying to keep it out if the limelight as much as possible.
And yes, formula 1 comparisons are unfair, but if they're actually within 30 seconds of DTM cars that seems pretty impressive.
The comparison that's really missing is to put a good racing driver in the same car and same conditions and seeing how much faster he can go. We're not testing the car here after all just the self-driving tech.

Still clearly some room to improve, but damn good for an autonomous car.
