There are rare Porsches that many know about - the 997-generation
911 Speedster (356 total) and 2010 911 Sport Classic (250 total)
come to mind - yet there are those special cars built in low
double-digit quantities that are exceedingly uncommon and far less
known. Take this lightweight series of 911s, for example. Just 20
1967 911 Rs were produced, only 21 1984 911 SCRS, and just seven
years later Porsche produced 22 Carrera 4 Lightweights. The 911
wasn't the only model in Porsche's lineup that received the
lightweight treatment in small quantities, and it was the 928 on
which Porsche engineers interestingly focused their weight saving
efforts.
Their initial efforts focused on four prototypes gifted as company
cars to each of the four factory 962 sports racing prototype
drivers that season: Jochen Mass, Derek Bell, Hans Stuck, and Bob
Wollek. All four loved the changes made to their prototypes
intended to comfortably transport them across the continent at high
rates of speed to the European races. In fact, Derek Bell enjoyed
his so much he kept it as his daily driver for 18 years! With such
a positive reception, Porsche made these changes available to the
public the next year as "M637" Club Sport option. Those 928s
optioned with M637 were approximately 120 kilograms lighter than
their S4 stablemates due to the removal of comfort features like
the rear wiper, a portion of the wiring harness, and PVC
undercoating. Heavier parts were lightened. The exhaust system, a
smaller AC compressor, and magnesium wheels special to the Club
Sport were added. In addition, the 928 Club Sport featured stronger
acceleration due to a modified final drive ratio, short shifter, a
limited-slip diff, a transmission without vibration dampening, and
sports seats. The Club Sport also featured lowering by 20
millimeters and a 150 millimeter wider track along with special
badging. Finally, the Club Sport was fitted from the factory with a
special "SP" stamped 5.0-liter V8 engine likely producing more than
the conservatively estimated 320 PS, due to special camshafts, a 1
mm increase in valve lift, a modified engine control unit, and a
higher rev limit. Following their tried-and-true path, Porsche,
along with their racing drivers, developed a 928 with more power,
lighter weight, and better handling - a true Porsche Club
Sport!
This matching numbers 928 Club Sport on offer is one of just seven
production lightweights built for 1989 and is the only example
finished in Forest Green Metallic over a Cashmere Beige and Black
leather interior. It was originally retained by Porsche AG as a
special "Werkswagen" company car for longtime Porsche employee
Bernd Kahnau. Kahnau was no mere employee. After his father's
passing - a longtime Porsche employee himself - in 1979, Kahnau was
personally recruited to work for Porsche at the request of Ferry
Porsche. The former BMW employee quickly became immersed in all
manner of important development projects, most notably as a
production planner for the 928, 911 Club Sport, 911 Speedster, and
911 models from the 993 to 991. Beyond being equipped with the
highly desirable Club Sport package, this rare 928 was optioned by
Kahnau with air conditioning, a tinted windshield, and a Blaupunkt
Bremen radio in addition to the sporting items inherent in ordering
a Club Sport. It is said that Kahnau was very attached to his Club
Sport, as the green on tan livery matched the colors of his English
country house! He owned it for approximately two years before it
eventually landed with an individual based in Switzerland, where it
was located until at least 2019.
Most recently, under current ownership, this matching numbers Club
Sport has been the focus of a lavish amount of attention totaling
over €65,000 worth of repairs and servicing between 2019 and 2021.
Most importantly, following a 33-point Porsche inspection at
120,800 kilometers in 2019, the car visited Landsharks in 2020 for
a new water pump, fresh coolant and engine oil, filters, and an oil
pan gasket. At the same time the thermostat was replaced, along
with the clutch disk and pressure plate, and engine electrical
items including the ignition cable, distributor cap and rotor,
spark plugs, and two knock sensors. Underneath, the Club Sport
received new brake discs and pads front and rear, a new brake
master cylinder, the replacement of the center catalytic converter
with lambda probe, and a fresh battery. This work along with other
sundry items and parts totaled €22,736.91. Following an accident to
the rear of the car, additional invoices from Landsharks that year
show the Club Sport was the recipient of cosmetic attention as well
with interior saddlery work, a new windshield, new seals, unibody
work to repair the rear accident damage, and fresh paint in its
original shade of Forest Green Metallic. In 2021, the air
conditioning system was refurbished with a new compressor, dryer
and a system clean with new liquids and fluids. Today, this rare,
well-preserved 928 Club Sport with its matching number engine and
transmission is offered with 122,748 kilometers at cataloging with
a copy of its Porsche Germany build sheet, recent service
paperwork, and manuals.
