Guest: Alastair Moffitt Host: Markus Voelter Shownoter: Alexander Grote
In this episode we talk about the design, engineering and testing of race cars. I have visited Toyota Motorsport earlier this year and talked with Alastair Moffitt and a few of his colleagues. We start out with an introduction to TMG (Alastair Moffitt), then talk about component and full-car testing (Marco Gehlen), and then discuss wind tunnels and aerodynamics (Antonio Pavesi and Rene Hilhorst). We also cover design trade-offs, team/driver integration, the role of the driver during development, the cockpit, the elements on the steering wheel as well as testing. We close with a look at additive manufacturing (3D Printing) in TMG’s work.

Great episode. Very much enjoyed listening to it. There is a nice little video about the car collection in the basement in YouTube: http://www.youtube.com/watch?v=GfjivmApqpc
Cheers,

Thanks for your comments and the link :-)

Klasse Sendung, hoffe mit den F1 Kollegen klappt es auch.
Viele Grüße,
Bastian
Da hat sich erst gestern was interessantes angedeutet :-) Mal sehen!
Outstanding work, Markus! I especially enjoyed the discussion about driving these cars in the museum.
Thanks Dirk :-)
You did it again Markus :-) Great episode!
My questions come usually afterwards ;-(
What I would like to know if not all these very small en mostly critical aerodynamics are not terminated or even turn against you when you closely chase your opponent in aerodynamic vortex?
Thanks Bert! That is a really good question! But it’s too late :)
Congratulations on another great episode Markus. I’m running a little behind with my podcasts so just listened to this one. I’m not much of a car fanatic but as usual it was so fascinating I didn’t want it to end. You have a wonderful interviewing style that is more like a casual conversation. Unlike some interviewers you don’t just follow a straight line of prepared questions regardless of the answers; if an answer doesn’t go where you thought it would you explore off the planned path and in taking those detours it brings the topic to life. Well done.
Thank you WileCau :-) I think one reason for this “interview style” is that sometimes it doesn’t feel to me like an interview, but rather like something I am personally interesting in that I have the opportunity to explore.
“Torsional stiffness” is the term you were looking for when explaining the aerodynamic model’s resistance to be deflect from torsional forces applied to it.
Thank you so much for this awesome interview series! It was great and you asked excellent and relevant questions.
Do take pictures on any of your facility tours, and where do you post them?
In very rare cases I take photos, for example here: http://omegataupodcast.net/2015/04/169-luftrettung-bei-der-drf/
But usually I don’t. Too much other stuff going on, and there’s 100s of photos of most things on the web anyway.
Great article! Thank you!
