i believe our friend OFSH used to own a 911 ( he currently owns Tesla Model S Plaid ) whereas i have never driven a 911 so it will seem more than a bit arrogant when i attempt to lecture him on the subject of Porsche 911 …
and yet i am going to share my concerns anyway.
Pictured: 2024 Porsche 911 Turbo:
every baller, power player, alcoholic and crackhead from Hunter Biden to Paul Pelosi drives a 911. it is the most iconic sports car ever. what Corvette is to American cars and Nissan GTR is to Japanese cars the 911 is to cars.
that said, the 911 is WRONG.
DECADES ago i told OFSH that 911 has engine in the right place ( as opposed to having it in the front ), but i was WRONG.
part of the reason i’m doing this thread now is to ATONE for that mistake.
some time after trying to misinform OFSH about the physics of weight distribution of 911 i got into an argument about it on SPEAKER BUILDING FORUM ( most guys who build speakers understand physics ) and i got deservedly SCHOOLED on the topic.
long story short - the optimum location for engine in a sports car is REAR MID SHIP which is where Formula 1 as well as every single modern supercar has their engine EXCEPT the 911.
pictured: Formula 1 Engine location:
the reason is two fold:
1 - the optimum weight distribution is somewhere around 45% front 55% rear.
2 - polar moment of inertia is minimized when the mass is close to the center of the car.
let’s look at weight distribution of some some good cars:
Formula 1: 46% front / 54% rear.
Bugatti Chiron: 43% front / 57% rear.
Porsche 911 Turbo S: 38% front / 62% rear.
I also recall the guy who designed the original 911 saying that 40% front / 60% rear would be “certainly unacceptable” - so by the standards of the guy who designed the original 911 the modern 911 is “certainly unacceptable”
so how come it works ? well because modern tire tech is beyond anything the guy who designed the original 911 could have dreamed of and is able to MOSTLY compensate for having the engine behind the rear axle.
the ONLY other cars i know of that put the engine in the rear ( as opposed to rear-mid-ship ) are BMW i3 REX
and Mercedes Smart Car.
the combination of great engine, great transmission, great suspension, great tires and great aluminum chassis and just how everything is tuned to work together makes for a great car IN SPITE OF the fact that the engine is fundamentally in the wrong place.
in other words the 911 is great because it is a Porsche and IN SPITE OF it being a 911.
