A rare and dramatic 1991 BMW 850i Koenig Specials KS8, showing 77,000 km and featuring a documented 6.0-liter engine conversion producing 450 hp.
Finished in striking Red Metallic and equipped with an automatic transmission, this heavily developed E31 represents one of the most distinctive interpretations of BMW's flagship 8 Series from the early 1990s.
The car is currently available in Germany and is presented in exceptionally well-preserved condition, with no reported rust or mechanical damage.
For collectors searching for a BMW 850i Koenig Specials for sale, a genuine Koenig KS8, or one of the more extreme European tuning creations of the 1990s, this is an exceptionally unusual opportunity.
BMW 850i E31 Transformed by Koenig Specials
The original BMW E31 8 Series was already one of the most ambitious grand touring cars of its era.
Koenig Specials took that foundation considerably further.
Based in Germany and famous for its radical conversions of high-performance European cars, Koenig developed the KS8 package specifically for the BMW E31 8 Series.
The transformation gave the elegant BMW coupe a far more aggressive personality through dramatically widened bodywork and extensive performance modifications.
The result is unmistakably an E31, but one interpreted through the extravagant German tuning culture that defined some of the most memorable performance cars of the late 1980s and early 1990s.
Koenig Specials KS8 Wide-Body Design
The Koenig Specials KS8 is immediately distinguished from a standard BMW 850i by its extensive exterior transformation.
Koenig's KS8 program for the E31 incorporated a complete wide-body treatment designed to dramatically alter the proportions of BMW's flagship coupe.
The conversion included specially developed components such as widened front and rear bodywork, redesigned aerodynamic elements, side treatments and other bespoke exterior components.
Rather than simply adding cosmetic accessories to the standard 850i, the KS8 created a fundamentally different visual identity.
Combined with this car's Red Metallic paint, the result is an unmistakable 1990s German performance coupe with extraordinary road presence.
6.0-Liter Engine Conversion — 450 hp
This BMW 850i has received one of the most significant elements of its Koenig transformation: a 6.0-liter engine conversion producing 450 hp.
The seller states that documentation relating to the engine conversion is present, including invoices and confirmation of the Koenig Specials modifications.
With 450 hp, this KS8 sits far beyond the specification of an ordinary early BMW 850i.
Power is delivered through an automatic transmission, preserving the grand-touring character of the E31 while adding substantially greater performance.
The combination of a large-displacement engine, rear-wheel-drive GT platform and distinctive Koenig bodywork captures the excess and engineering ambition associated with Europe's most extreme tuning houses during this period.
Only 77,000 km
The car has covered 77,000 kilometres, notably modest mileage for a 1991 performance automobile.
Mileage becomes particularly important with a specialist conversion such as a Koenig Specials car because many modified performance vehicles from this period experienced intensive use or underwent repeated changes throughout their lives.
This example is presented as a carefully maintained and well-preserved car.
Its mileage, condition and surviving conversion documentation all contribute to its appeal as a collector-oriented E31.
Red Metallic Exterior
The car is finished in Red Metallic, a colour particularly well suited to the dramatic KS8 bodywork.
While the standard BMW E31 was characterized by restrained, elegant grand-touring proportions, the Koenig treatment gives the vehicle a dramatically wider and more aggressive appearance.
The vibrant metallic finish emphasizes those distinctive proportions and allows the specialist bodywork to become the visual focus of the car.
For enthusiasts of period tuning culture, this is precisely the kind of uncompromising styling that made Koenig Specials internationally recognizable.
Well-Preserved Condition
According to the seller, this 1991 BMW 850i Koenig Specials remains in beautiful condition.
The vehicle is reported to have:
No rust
No mechanical damage
Well-preserved exterior condition
Well-maintained interior
Documented Koenig conversion work
Documentation relating to the 6.0-liter engine conversion
The combination of condition and supporting documentation is particularly important for a modified collector vehicle, where confirming the provenance of specialist work can significantly distinguish an authentic period conversion from a later replica.
Luxury E31 Interior
Despite the dramatic exterior and performance modifications, the car retains the luxury-oriented character that made the E31 BMW's flagship coupe.
Reported comfort equipment includes:
Leather interior
Heated front seats
Driver lumbar support
Front-passenger lumbar support
Automatic transmission
Extensive electrically operated comfort equipment
The E31 was conceived as a sophisticated long-distance grand tourer rather than a stripped-out sports car, and this KS8 retains that fundamental character.
That combination of luxury and extreme performance is central to its appeal.
A Product of 1990s German Tuning Culture
Cars such as the Koenig Specials KS8 represent a very specific period in European automotive history.
During the late 1980s and early 1990s, specialist German tuning companies regularly transformed flagship BMW, Mercedes-Benz, Porsche and exotic models into highly individualized performance machines.
These conversions often involved far more than wheels and cosmetic changes.
Wide-body construction, major engine modifications, suspension upgrades and bespoke interior treatments allowed customers to commission cars that were dramatically different from anything available directly from the manufacturer.
The KS8 is one of the clearest examples of that philosophy applied to BMW's E31 platform.
The BMW E31 850i Foundation
Introduced at the end of the 1980s, the BMW E31 8 Series represented a new technological flagship for BMW.
Its low-slung coupe proportions, pillarless side profile, distinctive pop-up headlights and sophisticated grand-touring character immediately separated it from BMW's conventional sedan range.
Today, the E31 has developed a significant following among collectors of modern-classic BMWs.
Specialist period conversions such as the Koenig Specials cars occupy an even more unusual category because they represent both the original BMW engineering and an important chapter of European tuner history.
A Rare Opportunity for the BMW Collector
A conventional BMW 850i E31 is already one of the defining BMW grand tourers of the 1990s.
A documented Koenig Specials KS8 with a 6.0-liter conversion and 450 hp is something significantly more unusual.
With its 77,000 km mileage, Red Metallic finish, automatic transmission, preserved condition and available conversion documentation, this example offers the opportunity to acquire a highly distinctive piece of German performance-car culture.
For buyers searching for a 1991 BMW 850i Koenig Specials KS8 for sale, a collectible modified E31, or simply one of the most visually dramatic BMW 8 Series conversions of its period, this car deserves serious attention.
