In the next part of our uber nerdy discussion about racing cars, the conversation turns towards F1, the season thus far, Audi progress and team shakeups.

If you’re following F1, then you’ve likely caughtSam Collins on the Apple feed. He’s the one ex-plaining the minute design details to the chagrinof teams hoping their latest changes go unnoticed. Sam’s made a career of unearthing racing secrets,including discovering underground test chambers.Of course we’ll also talk F1, but will save that fornext episode since this one went quite long.

Given Bob Tullius' passing, catching up with pro driver Hurley Haywood just seemed like the right thing to do. Hurley drove for Bob in the years Tullius' team Group 44 campaigned the Audi 200 quattro in Trans-Am and the 90 quattro in IMSA GTO.

One of just two American journalists who traveled to Morocco to drive the new Audi RS 5, Car & Driver Editor in Chief Tony Quiroga tells us all about it, how it drove, how it handled and how it handled the weight.

John Hanlon is a major force in the world of preservation & restoration of historic Audi racing cars. At the moment, he's got the 1992 Audi S4 GTO, the final racing evolution of the Audi 5-cylinder engine, listed for auction on collectingcars.com. We caught up with him to chat about the car, though the conversation covered so many other subjects.

The new Audi RS 5 has dropped and it's got everyone talking. Most agree it looks like a home run, but is it too heavy and is Audi bringing it to America? Amidst that, there are executive changes going on at Audi. How will it all play out and will petitions like Nish's help make the Avant happen?

We can all be a little jealous of Jeff Glucker. He attended the Audi Revolut F1 launch in Berlin and has also driven the S1 Hoonitron. We caught up with him to talk F1 and ended up covering all of that and more.

Making the run to Allentown, PA for Carlisle's Auto Mania event with Garage 44's Adam Eisenhauer is an annual tradition. Now throw in a flash snow storm, closed highways, smashed cars, stranted motorists and new Vredestein Quatrac Pro + tires on the SQ8 and you have the makings of a trip worth recounting. Survive all that and we also revisit the Auto Mania experience.

Nishant Pillai is a savant when it comes to tailored blue cars. That he has a pair of matching Nogaro Blue builds including an RS 6 Avant RS Tribute Edition and Porsche Paint to Sample 911 GT3 RS is a legitimate Nogaro flex.

In the last few months since Auditography was last on the show, he's driven the Concept C, met with Audi CEO Gernot Döllner attended an F1 Grand Prix and reviewed a number of Audi models for his YouTube channel. We catch up & chew the fat.
