The 356 SL (The Gmund Coupe)
Porsche's first
official racing entry was the 356 SL which appeared
at the famed Le Mans 24-Hour endurance classic in
1951, winning the 110cc category to begin a record
of success that continues to this day. These cars
were based on the hand built aluminum-bodied Gmund
coupes constructed between 1948 and 1949, before
Porsche moved back to Stuttgart from the Austrian
mill town. With that move came the revised
steel-bodied 356's which rendered the Gmund
coupes obsolete.
When representatives from
Le Mans approached Porsche about participating in
the event, the left over Gmund 356's seemed a
perfect solution, being far lighter than their newer
counterparts. The 356 SL Gmund coupes achieved an
outstanding record of success, not only at Le Mans,
but also in a number of other events, ranging from
rallies to speed record attempts. In all they served
the factory from 1951 through 1954. Several also
raced in North America, carving out their own
winning tradition.
The 550 Spyders
The first 500's
appeared in 1953. These were the first true
competition-bred Porsches; lightweight, two seat,
aluminum bodied, tubular framed, open-topped cars.
The initial pair of 550's was unique unto
themselves, racing only with Volkwagen-derived
pushrod boxer four cylinder engines, fitted with
detachable roofs. These dominated their class at Le
Mans finishing one-two in the 1500cc division.
Later, one of them won its category in the famed Pan
Americana Mexican road race.
Subsequent 550's, all
fitted with the four-cam Carrera flat four cylinder,
carried on what the initial 550's had started.
The became the dominant cars world wide in the small
displacement sports racing categories in the
factory's hands, but also in the hands of
Porsche's customers who purchased every one of
the quick little cars they could find.
In 1956, Porsche introduced
a slightly modified Spyder, the 550A. This shocked
the racing world when it won the brutal Targa Florio
road race outright in its debut appearance, humbling
such well-known and much more powerful rivals as
Ferrari, Maserati and Jaguar. During the next five
years the 550A continued winning, for the factory,
and the factory's customers in almost every
venue where it competed. Indeed, it was a car that
got more attention for its occasional loses than it
did for its nearly non-stop string of
victories.
The Type 718 Spyders
The next step in
Porsche's Spyder saga came in 1957 with the
introduction of the Type 718, initially known as the
"RSK" for its uniquely configured form
suspension. In various forms, the Type 718 would be
raced by factory and customers through the end of
1964. During that period it achieved an outstanding
record which not only included class triumphs, but
outright wins at the Targa Florio and in 1960, at
the prestigious Sebring 23-Hour long distance affair
in Central Florida. Many famous drivers, including
American Dan Gurney, as well as Wolfgang von Trips
and Jo Bonnier helped to polish their careers behind
the wheel of the Type 718.
The most famous example of
this Spyder variant was the W-RS, which was
constructed in 1961 as a four-cylinder entry. The
following year, fitted with a 2.0-liter flat eight,
it began to win everywhere it went. It took
important class victories not just in the great road
races such as Le Mans and the Nurburgring, but also
in the hillclimbing arena. Long a benefit for
Porsche Spyders, it claimed the season championship
with Edgar Barth in 1963 and 1964 before it was
retired to the Porsche Museum.
The Type 718 and 804 Formula Two and Formula One
Single Seaters
In the late 1950's the
Porsche factory began its involvement in Formula
racing by running virtually standard 550A Spyders.
In the Formula Two portion of the annual German
Grand Prix at the Nurburgring, in 1958, Jean Behra,
driving a modified Type 718 RSK Spyder with its seat
located on the chassis centerline won the Formula
Two race at the Rhiems circuit in France.
In 1959 and 1960, Porsche
produced an open wheel, single seater version of the
Type 718, using this to dominate the Formula Two
championship during that latter Season, the last for
the 1 5-liter formula The next year. When Formula
One adopted the 1.5-liter displacement cap, Porsche
appeared poised to claim the World Title.
Unfortunately, things didn't go Porsche's
way; the Type 718 being outclassed by Ferrari's
Type 156 V-6.
For 1962, Porsche
introduced the Type 804 that abandoned
Zuffenhausen's traditional flat four cam,
four-cylinder for a new boxer eight. While the
engine was competitive, and indeed could be found
for many years thereafter powering Porsche sports
racing prototypes in 2.0 and 2.32-liter form, the
Type 804 could not keep up with the British BRM and
Lotus V-8's.
In all, the 804 won only
twice, coming home first in the French Grand Prix at
Rouen and again on its home turf at the Solitude
Ring outside 01' Stuttgart in a non-points
affair, Gurney being the driver on both occasions.
At the end of 1962, Porsche withdrew from Formula
One, not returning to the sport until 1983 as an
engine supplier for McLaren.
The Type 904
Often referred to as the
first of the "modern" Porsches, the 904,
developed in 1963 and first raced in 1964, featured
another "first" for Zuffenhausen, a full
fiberglass bodied coupe, bonded to a steel channel
frame. Intended to use the new boxer six from the
then just introduced 911, it wound up employing the
aged Carrera four cam four-cylinder instead. Even
so, this engine was enough to help the 904 dominate
the 2.0-liter production sports car class for
Porsche for the next two years. That success was
achieved mainly by Porsche's customers, the
factory concentrated on running a small fleet of six
and eight cylinder powered 904's of its own in
the 2.0-liter prototype category.
As had its customers, the
factory came dominate the division with its coupes,
enjoying nearly total success from Daytona and
Sebring through Le Mans in 1964 and '65. The
only blemish on the 904's record came in 1965
when it was defeated in the hillclimb arena by
Ferrari's Type 166 Dino Spyder. In an attempt to
keep the 904 on par with its Ferrari rival. Dr.
Ferdinand Piech, the newly appointed head of Porsche
racing, converted the 904 from a coupe to an
open-topped car. Those efforts were in vain;
however, they led Piech to pursue new directions in
design that would take Zuffenhausen to the top of
the sport.
The Type 906, 910, and 910 "Plastic"
Porsche Sports Racing Coupes
With the failure of the 904 hillclimb Spyders, in
August 1965, Piech and his engineers introduced a
tubeframe open topped car created over a three-span,
that utilized the hubs, brakes, and 13-inch diameter
wheels from the Type 33 Lotus single Formula One Grand
Prix racer. Dubbed "the Ollon Villars" Spyder
after its debut event, this was the foundation for all
of Porsche's subsequent prototypes up through the
famed 917's and later the 936's that last won
at Le Mans in 1981. Although this important car
didn't beat the Ferrari - due largely to a lack of
development, it did win the hillclimb crown in 1966,
ironically using a coupe body.
In January of 1966, the car
that the Ollon Villars Spyder had spawned, the
Carrera 6, or 906, made its debut. Intended strictly
as a circuit racer, this coupe featured the earlier
car's tubeframe, however, it didn't have the
Spider's advanced suspension. Rather it used the
same running gear as the 904, with its rather
antique 15-inch diameter wheels. This retrograde
step was forced on Piech by his uncle, company head
Dr. Ferry Porsche, who did not want to waste the
suspension components completed in anticipation of a
second batch of 904's - cars canceled in favor
of the 906.
Despite the compromise, the
906 took up right where the 904 left off, dominating
the two liter 2.0-liter production sports car
category using finally the 911's six cylinder
engine. As with the 904, the factory ran several
906's on the 2 0-liter prototype category, some
in long tail form and some with the boxer eight. No
matter which version, or which class, the 906
dominated; winning victories at all the major
international events. Even on occasion challenging
for the outright honors - this despite the then
intense battle between Ford and Ferrari for
domination of the sport.
Despite its success, Piech
remained unhappy with compromised 906. By the summer
of 1966, his engineers had produced its replacement,
the 910. Virtually identical to its predecessor,
with the exception that it had abandoned the
904-suspension design run in the last hill climbs of
the season, the 910 showed much potential. Over the
winter this was developed into reality. The new
coupe debuted in the 1967 Daytona 24-Hour endurance
event with a class victory. Interestingly while
there were both six and eight cylinder versions of
the 910, the car was never intended to achieve
"production" status. However, because of
Piech's edict that new cars be used at every
race, enough were built that the six-cylinder 910
did eventually qualify as "production sports
car".
Like the 906, the 910 was a
winner, the highlight of its career being an
outright triumph at the Nurburgring 100 KMs in 1961.
This came on top of its similar performance in the
Targa Florio where it collected the overall honors.
With these, as well as several other high overall
placing, the 910 had propelled Porsche into the
thick of the 1967 contest for the World
Manufacturers crown with Ferrari.
Even so, Piech was getting
ready to sell his 910 fleet to Porsche privateers,
having pushed the envelope even further with the
introduction of the new 907 at Le Mans that June.
While all subsequent versions of the 907 would be
eight cylinder powered, these two long tail coupes
used fuel injected flat sixes While one retired, the
other won its class, finishing high up in the
overall rankings.
For the 1967 Brands Hatch
season finale Porsche fielded both a short tail 907
as well as the venerable 910 in an effort to upset
Ferrari. This was not to be as the Italians finished
ahead of Zuffenhausen in the British affair to take
home the coveted championship. Porsche would achieve
some measure of revenge the following January at
Daytona where three 907 long tails would sweep the
two, three places in the American 24-Hour.
That was a good beginning
to what Porsche hoped would be its first
Manufacturers crown. Fueling those aspirations was a
change in the regulations which now limited all
prototypes, such as the 907 coupes to a maximum of
three liters, the international authorities having
summarily banned the big Ferraris and Fords from the
scene in a hasty decision made after Le Mans the
previous June.
Such was the tightness of
the time frame, that officials decided that
production sports cars of which at least 50 examples
had been made, could race as long as their engine
displacement didn't exceed 5.0 liters The short,
and long term effects of this were to be huge. In
the meantime, though, Porsche and Piech weren't
worried as they were about to introduce their own
3.0-liter prototype, the 908 - a 908 fitted with a
simple eight -cylinder powerplant based in large
measure of the 911's boxer six.
The 907 would soldier on
throughout 1968 while Piech's men would struggle
to make the initially troublesome 908 an effective
tool to accomplish Zuffenhausen's goal of
winning both at Le Mans and in the Makes title
chase. Unfortunately, the aging but reliable Ford GT
40 came away with both those prizes. The 908 was
constantly breaking down, while the 907 didn't
have enough "punch" to stay even with the
John Wyer run, Gulf Oil sponsored Fords. Things
would be different, however, in 1969.
The Type 908
Perhaps more than any of
the other cars of its era, the 905 was unique. It
started life as a clone of the 907 with a new,
simplified Type 901 boxer six derived 3.0-liter flat
eight. It wound up Its career in the early
1980's with a completely different chassis, and
a turbocharged six cylinder powerplant akin to what
could be found in the 934-935 silhouette prototype
coupes as well as the 936 prototype Spyders.
When it was first
introduced in the spring of 1968, however, the 908,
both in short and long tail forms were virtually
indistinguishable from its 907 predecessor. Only the
keenest of eyes noting the slightly different air
ducting, and the slightly revised rear aerodynamic
package of the "langhects" that included a
full width wing and movable, suspension activated
flaps.
Although the 908 won the
1000 km event at the Nurburgring in only its second
race appearance, engine vibration woes kept it from
achieving further success that year. The best the
new coupe could do was a third at Le Mans, which had
been pushed back from its usual June date to
September by political unrest in France. The
following year was to be quite different; this
despite the utter failure of the 908 charge in the
season opening 24 Hours of Daytona, where again
engine problems sidelined Porsche's hopes for a
victory.
After that, with the
exception of its close defeat at Le Mans by Jacky
Ickx's Gulf Wyer Ford GT-40, the 908 ran
flawlessly to give Porsche its first ever World
Manufacturers title. The disappointment of losing at
Le Mans was indeed painful, however, the overall
success achieved was something of which Zuffenhausen
and Piech could be proud. Interestingly, these
accomplishments in large measure came not with the
traditional long tail coupes, although these were
used at high-speed tracks such as Daytona. Monza,
Spa, and Le Mans, but rather with a new open-topped
Spyder, the 908-02.
This came into existence
because of a new set of regulations for the
3.0-liter prototypes, which permitted the simplified
bodywork configuration. Actually, there were two
versions of the Spyder in 1969; the original whose
flowing fender lines followed those of the coupes,
and the later 908-02 "flunder". This car
featured a flat upper surface that produced a
pleasing overall shape that would later spawn the
body design for the first 917 Can-Am Spyders.
No matter what the body or
chassis configuration, the 1969 908's all
featured a revised engine that employed a new
crankshaft, which eliminated the vibration problems
that had so plagued it the previous season. Such was
the competitiveness of the 908 and its modified
eight-cylinder that after factory use the cars
continued to be campaigned for another five years or
so in private hands, often challenging their younger
rivals for the top honors in their class. Perhaps
the most famous of the 908's customers was movie
actor Steve McQueen who took his 908-02 Spyder to
second overall and first in the prototype division
at Sebring with Peter Rebvson as his co-driver in
the run up to his movie "Le Mans".
While the 908 had been
largely consigned to the back burner by the new 917
12-cylinder in 1970, it had not quite finished its
service for the factory. Realizing that the heavy
917 would be unsuitable for such events as the Targa
Florio and the Nurburgring - both of which were
extremely important to Porsche, Piech and his
engineers produced a new 908. The 908/3, used the
standard 908 drive train, but otherwise was based on
a lightweight 1968 hillclimb Spyder, the 909.
As a factory entry, the
908/3 saw service in just four events, the Targa
Florio and the Nurburgring rounds of the
Manufacturers Championship in both the 1970 and 1971
seasons. Of these appearances, the 908/3 was
victorious three times, winning the Targa Florio in
1970 and the Nurburgring both years. After that the
cars were sold off. In 1975 several were fitted with
turbocharged sixes, Herbert Muller using his Martini
example to help him win his second straight
Interserie title that year. The cars continued to
soldier on through the first part of the 1980's
- still surprising competitive -until the new Group
C prototype regulations came into force in 1982.
