History
This model year introduced the intercooled version of the 930 with
the whale tale that defined Porsche's first supercar. Not only is
the 930 a highly collectible car with an iconic look, but it also
has the remarkable history of being the only homologated road car
to win the 24hrs of Le Mans outright in 1979 by Porsche Kremer
Racing. It was at the head of the pack in its day and the
performance still impresses today.
There are good arguments to be made that the Porsche 930 (AKA the
911 Turbo) was the first civilized supercar. As reliable as an
anvil and the fastest car on the German Autobahns for almost a
decade, it proved that high performance didn't have to be finicky.
As long as you were skillful enough to drive it to its
potential.
