In the Moments of Truth series, Audi links the technology developed for its successful racing efforts back to its newest high-performance street cars, the RS 5 and the TT-RS. The latest video covers the trickle-down of Audi’s “Ultra” lightweight construction from its 2011 Le Mans Prototype cars to the new RS 5 coupe, which we're driving this week and will post a review on shortly.
Lighter weight, of course, translates into faster acceleration, shorter braking distances and higher cornering speeds (assuming the rest of the car is designed accordingly). On the street, that delivers benefits like fuel savings and reduced emissions; on the track, it returns lower lap times.
If you’ve missed the other videos in the the Moments of Truth series, we say they’re worth watching. The first installment covered the heritage of Audi’s in-line five-cylinder engine, linking the new TT-RS to the Hans Stuck-driven Audi 90 Quattro, which enjoyed success in IMSA’s GTO series.
The second video links the RS 5 and Audi’s 2001 endurance racer, the R8. Covering the automaker’s FSI (Fuel Stratified Injection) technology, the video explains the benefits of optimal and precise fuel metering to both race cars and road cars. FSI is currently used throughout much of Audi’s lineup, demonstrating the benefits racing brings to a manufacturer.
