Porsche 928 history

1978-79
The first couple years the 928s were almost hand built cars. The
quality in many areas was later reduced in favor of higher production
numbers in an attempt to capture market share. The features that
distinguish the early years are simpler electronics and the CIS fuel
injection system. This is a very simple, reliable and responsive
injection system that sacrifices fuel economy for performance. A
higher performance CIS system was retained on the EURO model until 1983.
Selling price estimation $28.000 USD
1980-83 The
1980 was the first full production model. The injection system was
changed to an electronic system that increased fuel economy at the expense
of performance. The engine size remained the original 4.5 liter but
was increased in 1983 to 4.7 liters. The door locking system was
changed from vacuum to electric and a factory alarm system was added as an
option. The percentage of cars made with automatics increased and
the with the larger engine in 1983 the four speed automatic was
introduced. Where the early cars offered the sun roof, right side
mirror and power seats as options, most all of the U.S. models after 1980
had these options as standard equipment. Finding that the injection
molding of dashes and other interior components had a high flaw rate,
Porsche covered the rejects with leather and started offering an all
leather interior. The 'S' model had a small tail fin. Selling price
estimation $38.850 USD
1984-86 - S2 The
euro version was equipped with a L-Jetronic injection and electric airflow
sensor. The S2 reference was never used by Porsche Germany but came mainly
from journalists. In the UK Porsche issued the 928s2 model with decal on the rear.
1985-86
- S3 The lack of overwhelming
success caused Porsche to redesign the car in 1985. The engine size
was increased to 5 liter and 32 valves. The injection system was
changed to a state of the art very sophisticated electronic system (L-H
Jetronic) that monitors all aspects of the engine including timing,
quality of the gas and habits of the driver. Six way sport seats
with a narrower seat back for better rear and side vision were
added. The manual transmission was improved for better
shifting. In 1986 anti lock brakes were added and mid year in 1986
(starting with VIN # 1000) improved multi piston brakes were
installed.
1987-91
- S4 Again Porsche extended the redesign
to many more facets of the car creating the S4 model. Major body
style changes were implemented with new front and rear bumpers and lights
that added six inches to the length of the car modernizing the look.
A larger rear spoiler, wider rear rims and tires were added.
Internally the engine was redesigned with better access for service and a
better torque curve. More electronics were added with features
like memory seats and mirrors, electronic gauges and electric cooling
fans. Selling price estimation $69.000 USD up to $73.000 USD
1988-89 -
CS (club sport) and SE (sport equipment, UK only) were
produced in only very limited numbers. The CS was a lighter and sportier version
of the S4 having weight reduction,
different seats, GT style wheels, sport suspension, and the latter also
has a modified engine and exhaust, close ratio gearbox, and LSD. The SE
had a few extra luxury options that were deleted in the CS.
1988 -
GTE (Gran Tourismo Executive) was
intended to be released, but actually one was ever built. It was intended
to become the next generation, and just one exists in Johannesburg. It
rated approx 360 Hp. Here's a document about this GTE:
928gte.jpg
1989-92 -
GT The GT had increased horse
power, wider rear wheels, sport suspension and brakes, electronic limited
slip differential , a tire pressure warning system and only came with the
5 speed manual. The S4 and GT models were made concurrently.
Selling price estimation $74.500 USD up to $76.000 USD
1992-95 -
GTS - The GTS had increased engine
displacement of 5.4 liters and increased horse power. Very few cars
were produced in the last few years of production and the price was very
high. Selling price estimation $80.920 USD
Porsche 942
The Porsche
942 was a special
edition of Porsche 928, made as a gift to
Ferry Porsche on his
80th birthday.

disclaimer: this is based on registered APK (expiration not longer than 6
months ago) plus still insured cars, data from RDW. The right column shows
the registered but apparently inactive cars. A part of those may not even
exist anymore. It contains adjusted model info since RDW is sometimes wrong.
(like in 1985 there were no S4)
Remark on the subject Horsepower:
If you want to talk "honest" hp, then we should out Porsche's
use of "European horsepower" whenever it quotes "hp" to a DIN standard. One
Euro hp = 75kgm/sec, which is approx 542.5 ftlb/sec compared to the imperial
horsepower (as used in SAE standards) which is 550ftlb/sec.
This is why the S4 is 316bhp compared to the rest of the world's 320bhp.
(but both have 236kW), and the MY 85/86 S3 is 288bhp, when it has 3 more kW
(215kW) than the 288bhp (212kW) Australian/German/Austrian/Swiss MY86 S3.
The S2's 310 hp is Euro hp; it actually produces 228kW and ... 306 real bhp.
(Thanks to Leonard Loeb for first explaining this anomaly to the list about
five years ago!)
The power required to overcome aerodynamic drag varies with the cube of
velocity, so if you had 326bhp instead of 306bhp at 5900rpm, you would
improve your top speed by about 3mph. (The S2 manual with stock wheels and
tires is about 75rpm under 5900 at 158mph and would be about 35rpm over it
at 161.)
