Vague steering? :finger I think not. One of the finer points of the uber beatle is it's ability to scurry about, changing direction in response to small steering inputs.
Hmmm, whale tails.
In the beginning was the 911. This was before aerodynamics was understood and the shape was not optimised.
Then the 911 2.7 RS hove into view, ducktail added. This removed the rather alarming amount of lift over the rear axle (several hundred kilos I think at Vmax
).
The first turbo had a whale tail for several reasons - to reduce lift, to improve cooling air flow through the engine bay, and a tinsy bit for styling. Now the styling bit was a bonus and not the main reason, but it didn't do any harm.
This spoiler appeared on other less well endowed models.
Other marques just stuck with brick like styling and went for grunt.
Making the car a smoother shape helped with the top speed but caused problems with lift.
The long rear window does not help - if it was vertical, you would have lots more drag but get rid of the lift issue.
Wind forward a bit, and things become a bit sleeker.
The current models manage the airflow carefully. Smooth underbodys, with discrete spoilers that only come into play when needed.
Porsche take the aerodynamics very seriously. Unlike some, like the Audi TT perhaps.
They know that people will drive their cars at top speed, and they make sure they will handle well. There is a big difference between 155 and 190+.
Each variant has a different design of bumper, and front and rear spoiler, all carefully tailored to give appropriate handling at the top speed.
Of course in the UK on the road, this is more engineering than you need.
Playing with the weight transfer is the key trait of the 911.
Applying power out of a corner (at any speed) the weight distribution aids traction.
It is not that easy, it is not as forgiving, although 40 years of evolution have produced a car that is very good, but I cannot see any front engined car beating one out of a corner (with like for like power to weight).
Regardless of what prejudice may say, the handling of the 996 version is quite benign. You can slide them (if you have the room) quite comfortably. Just don't bottle it, and lift. Once you are committed stick with it.
