Gaston is probably trying to figure out where he can get a $2000 pair of Ferrari driving loafers


I don’t own anything expensive.

That is a Gnome rotary radial engine. Unique in that the crank was fixed and the cylinders and prop rotated around it.
Interesting concept to say the least.

A plane with that in it must have a turning radius measured in miles. That's a massive gyroscope to rotate.

ETA: On the other hand, it probably made for snap turns in the other direction.

I understand your point, but Mercedes-Benz was designing and engineering long before there was Ferdinand Porsche.


I apparently wrote poorly in that I was not disagreeing with you. It is hard to argue over the life of cars MB is not the innovation leader. Even of the last few decades if you wanted to imagine the standard/optional equipment for an average family sedan 10-20 years in the future just look at the current S class.

I was separating manufacturers primairily know as sports car manufacturers since they tend to have less R&D money and focus more on pure performance and trickle-down race car tech. Even when it comes to F1 tech Ferrari is arguably one of the most conventional thinkers on the grid. My point being even in this smaller pond they aren't the most cutting edge, quite the opposite in fact. That also isn't to say their cars and brand don't have an aura that is unmatched.

I saw one in a museum and it looked like a nightmare to keep in service.

You saw my ex-wife in a museum?

I mean, I've never of a museum with a bar, but hell, you never know.

My favorite engine with gear-driven cams was a Honda VFR (because I owned one), but apparently the gears are between the two cylinders so you can't get a good picture of them. So instead, I'll see your Enzo and raise you one Ducati Desmosedici RR (street version of a Ducati MotoGP bike):

What was the advantage of that?

Radial engine

Good lord. I work with very precise CNC machines that are at the forefront of the technology of the industry. We make precision medical instruments and hold tolerances of .0001 all day.

With that said, I imagine that thing is pretty old and cannot fathom the amount of time that went to setting up and cutting all those gears and components back then. That is the type of stuff that just blows my mind. I've got a shop full of very smart guys and 90% of them wouldn't know where to begin on something like that working with conventional machinery. Damn impressive.

No man, I've sold all of my new(er) toys. I'd purchase them and then they would end up sitting in the garage for a multitude of reason, none to do with the actual car.

Love the Turbo/S but there is a guy in the neighborhood has a 991 GT3, looks and sounds fantastic.

It's likely my misreading rather than your writing.

Rereading, you are absolutely spot on. Porsche has in fact took the lead in the later part of the 20th century and continues into today. I mean, looking back at the 959 and all the things that made the car is still used today not only by Porsche, but borrowed and used by other manufacturers. At one time people purchased Ferraris to announce "they made it". I'm seeing more buy a 911 variant instead of the Italian, that says a lot.

It's quite remarkable that Porsche is able to package such a great performing and beautiful product, but to make it daily driver friendly and reliable is absolutely astounding.

My only fear is that i'll miss that V-8 sound, but what you wrote surmises my opinion of the 911.

The 2020 cars are not yet widely available, but they do have several significant improvements over the previous gen.

I really hate that shifter though.

I bet when one of those sheers though, it probably is crazy expensive to fix

This looks like one of those diagrams you see on aptitude test. ASVAB. 'If this gear turns such and such way, which way does this gear turn', and all that.



Seen something similar on motorcycles.

Ducati's, just to name one. Like I said, motorcycles.

NIST still uses manual precision lathes to make standards and gauges. Those old mills and shapers had tons of good iron and steel in them, hand scraped ways and beds, and operators that took pride in their work and knew the quirks of the machines to get the best results out of them. I worked at the old AAP in Minden for a few years and one of the lines had an old Pratt and Whitney engine lathe collecting dust in an abandoned bay.
