Has anyone ever made a 7 or 9 cylinder engine?
Discussion
Seriously for a moment, I wonder what a in-line 7 would sound like?
I mean, we're all familiar by now of the smooth but dull hum of an I4, the off-beat mechanical thrum of a 5, the silky smoothness of a V6/I6, the Hollywood gurgle of a proper V8 etc.
What would a I7 sound like, in an application suitable for a car?

Just one of those thoughts that pop into my head now and again.
So has there ever been a V7 or Straight 9 etc, engine ever been made?
Wonder what they would sound like?
If they have never been made I wonder why that is.
I know that you can/could buy a 3 cylinder Corsa and recall that a number of manufacturers have built prototype odd-number units - it would be interesting to hear why they never made it into production.So has there ever been a V7 or Straight 9 etc, engine ever been made?

As far as I know, there has never been a 7-cyl or a 9-cyl engine in production in a private car. I seem to recall that some mad inventor produced a 9-cyl radial-engined prototype in France in the 1930s, but nothing came of it.
Interestingly, Graham Robson's new book on Standard, just published, goes into great detail about Standard's World War 2 activities, when they were much involved in making thousands of Bristol Mercury aircraft engines, which were 9-cylinder radials. A bit big for adaption to private cars though ....

So 5 is still the biggest number of cyclinders we know of in a non-radial engine? I suppose a nine could be arranged in a kind of 'trident' formation quite neatly.
What would be odd is a engine with a prime number
of cylinders. 5 is still winning that race....Many Aircraft have 7 and 9 cylinder engines, I think 9 is the optimum configuration, any more than that and they tend to do them in 9 Cylinder rows, hence the big bombers and airliners having 18 cylinders.
Of course if you want a 400BHP 7 cylinder Supercharged Bike, go and take a saw to a Yak:
