Audi Urban Concept preview

Following this past weekend's spy shots of the new urban concept caught on a film set in Berlin, Audi has released a set of sketches of the all-new 1+1-seat vehicle set for its global unveiling in Frankfurt.

Fuel Injection Pioneer Stuart Hilborn 1917-2013

Stuart Hilborn, the dry lakes hot rodder whose racing fuel injection systems powered almost the entire field at Indianapolis some years, died Monday at the age of 96.

That new P1 front end new LED headlights mark the 650S out from the 12C, with a more integrated front splitter increasing downforce and door blades behind the front wheels directing air from the trailing edges of the splitter for better front end grip.
