The 1994 RUF BTR4 Coupe stands as one of nine all-wheel-drive examples built on the 964 platform, and this car pairs rarity with extensive documented updates. The 1994 RUF BTR4 Coupe focus keyphrase reflects its position as a true low-production model with a detailed history.
Factory Build and Early Background
This coupe was delivered new to Japan through Ishida Engineering. It began life with a turbocharged 3.8-liter flat-six and a six-speed manual transaxle equipped with an electronic clutch system.
While in Japan, the clutch was converted to a three-pedal hydraulic setup. The update improved engagement and gave the car a more traditional RUF driving feel.
Exterior Design and Aerodynamic Elements
The car wears Polar Silver Metallic, a finish that highlights the sharper lines of the BTR4 body. A front air dam, a “tea tray” wing and a model-specific rear valance define its profile.
Aerodynamic mirrors and a painted tail panel add final touches. These elements help distinguish the BTR4 from standard 964-based builds.
Wheels, Brakes and Suspension
It rides on 18-inch RUF Speedline wheels refinished in 2024. They measure 8.5 inches front and 9.5 inches rear with polished lips and Michelin Pilot Sport 4S tires.
Bilstein shocks support the chassis, while drilled rotors and black calipers manage braking. A front strut brace adds rigidity to the structure.
Interior Customization and Features
The cabin was reworked by Rstrada in California. The interior features Sport seats trimmed in blue Studio Check fabric and matching rear jump seats.
A bespoke bulkhead panel and gray leather dashboard give the space a cleaner tone. A 996 shifter assembly and square-weave carpets complete the updates.
Instrumentation and Cabin Details
A blue-dial RUF tachometer sits behind the wheel. The speedometer was converted to imperial units in 2022, and the odometer shows 33k miles.
Upgraded climate components include a new evaporator, blower motors and receiver-drier. A Nakamichi CD unit, aluminum pedal pads and power windows add usability.
Power, Engine Specs and Performance
The 3.8-liter turbo flat-six produces 415 horsepower thanks to RUF’s displacement increase and Motronic injection. The engine was removed in 2024 for a service that included new gaskets, a fuel pump and ignition components.
The six-speed manual delivers power to all four wheels, and the hydraulic clutch setup complements the car’s mechanical balance. A 997 Turbo dual-mass flywheel and a new clutch disc were installed in 2024.
Service Records and Documentation
The car includes import documents and 2019 correspondence from RUF confirming production details. Additional service invoices from Rstrada exceed $88,000.
A clean Carfax report accompanies the vehicle along with literature and ownership history, giving buyers a clear view of its maintenance path.
Summary
The 1994 RUF BTR4 Coupe blends rarity, mechanical depth and documented upgrades. With its Polar Silver finish, 3.8-liter turbo engine and AWD layout, it stands as a detailed and well-kept example of RUF’s early 1990s engineering.
