Overview

Subaru's Leone-derived RX Turbo was a production-based turbocharged all-wheel-drive rally entry operated by Subaru Rally Team Japan/Fuji Heavy Industries during selected World Rally Championship rounds in the mid-1980s. It must not be represented as Subaru's first rally car: earlier Leone variants had already carried the marque into long-distance rallies. Nor was this a Prodrive-built Impreza or Legacy works car; Subaru's later full-scale international programme was a separate engineering era.

The 1.8-litre EA82 turbo horizontally opposed four-cylinder and four-wheel-drive drivetrain were fundamental to the RX Turbo. Road models had different gearbox types and selectable/full-time four-wheel-drive packages by region and year. A single street specification should therefore not be assumed to describe every race-prepared Group A car's differentials, ratios and engine output. Period technical figures near 190 bhp circulating in secondary archives require an individual works car sheet before being treated as exact.

The best established international result for the RX Turbo came in Kenya. The 1986 Safari Rally classifications place Mike Kirkland with Robin Nixon sixth overall, and Frank Tundo with Quentin Thomson seventh, both in Subaru RX Turbos classified Group A8. These were not outright WRC podiums or a Safari overall victory. The model remained in Subaru's 1989 entries, including Peter 'Possum' Bourne's tenth place at the 1989 Rally Australia, before the later Legacy RS transition.

Technical Specs & Innovations

Vehicle family: Subaru Leone (third-generation) RX Turbo, production-derived rally coupe/sedan depending chassis
Competition regulations: FIA Group A production-based class, not Group B special and not 1990s Subaru Impreza WRC
Rally-team identity: Fuji Heavy Industries / Subaru Rally Team Japan, with period preparation before the Prodrive works partnership
Common engine: Subaru EA82 horizontally opposed petrol four-cylinder, forced-induction road/rally family
Engine physical capacity: Approximately 1,781 cc (1.8 litres) in the EA82 turbo family
Engine layout: Front-mounted longitudinal flat-four (boxer) with horizontally opposed cylinders
Turbocharger: Single exhaust-driven turbocharger with production-origin charge/fuel systems modified for competition
Valvetrain: SOHC two valves per cylinder in many EA82 turbo variants; verify head variant per homologated rally chassis
Fuel management: Electronic petrol injection, stage-engine management/calibration varying by team and year
Road-versus-rally power: Market EA82 turbo road ratings not a reliable proxy for specific 1986 Group A Safari output
Published rally-power caution: Secondary preparation compilations quote roughly 190 bhp at 6,500 rpm; unverified for a named surviving 1986 works chassis
Drivetrain: Four-wheel drive; selection/centre-coupling mechanics evolved across road and rally model years
FIA actual class: 1986 Safari Group A8 under period regulations; class result not an overall WRC group-B podium
Gearbox: Manual competition gearing with four-wheel-drive transfer architecture based on Leone family
Front differential: Stage calibration and homologated modifications vary; do not invent one all-years differential locking system
Rear differential: Driven rear axle assembly, competition differential choices and traction regulation
Bodyshell: Strengthened road-derived steel body with FIA cage and long-distance rally protection
Suspension: Independent rally strut-based architecture with appropriate rough-stage travel and dampers
Front/rear engine packaging: Low boxer engine centre of gravity, but front placement still influences mass transfer and turn-in
Tyre configuration: Gravel/snow/tarmac selection; reinforced tyres and spares essential on East African long-distance rallies
Safari mechanical preparation: Extended-duty cooling, filtration, suspension and guards for high-mileage Kenyan route
Crew seats: Two-person WRC competition harnesses, cage and navigation equipment
1986 Subaru team manager: N. Takaoka in contemporary WRC team-season compilation; chief engineer Y. Kimura
1986 Safari crew #5: Mike Kirkland / Robin Nixon, sixth overall
1986 Safari crew #19: Frank Tundo / Quentin Thomson, seventh overall
1986 works result metric: Team-season archive reports zero outright wins and zero overall podiums; two contested rounds in 1986
1989 Rally Australia result: Peter 'Possum' Bourne / Rodger Freeth tenth overall in RX Turbo per complete event classification
Next technical era: Subaru Legacy RS began its full-fledged rally programme in 1990, with manufacturer WRC victory not until 1993
Data boundary: Do not use later Impreza WRX STI EJ20 2.0-litre turbo figures, drivetrains or championship totals for the EA82 RX

🏆 Competitive Highlights

Pre-1985 Leone rallying: Subaru had earlier internationally rallied the Leone, so the RX Turbo was a technical continuation, not the first Subaru rally debut.
1985–89 RX Turbo period: Fuji Heavy Industries and Subaru-affiliated entrants used the Leone RX Turbo on selected international, Japanese and regional rallies.
1986 Safari Rally sixth: Mike Kirkland/Robin Nixon finished sixth overall in Subaru RX Turbo, first among Group A classified finishers.
1986 Safari Rally seventh: Frank Tundo/Quentin Thomson finished seventh overall in a second RX Turbo, behind Kirkland in Group A8.
1986 Safari attrition: Possum Bourne/Mike Fletcher retired with suspension damage, while several other RX Turbo entries failed to finish.
1986 Subaru WRC season: Team compilation records two rallies contested and six starts, with no overall stage wins, event victory or podium.
1986 New Zealand campaign: The RX Turbo appeared in the 1986 WRC event, but team-season records list withdrawn works entries rather than a documented Subaru podium; exact withdrawal reasons require verification against the original event bulletin.
1988 South American activity: Subaru continued selected regional and WRC appearances, including Argentine outings in the Leone RX family.
1989 Rally Australia: Peter 'Possum' Bourne/Rodger Freeth finished tenth in a Subaru RX Turbo; Toyota's ST165 won.
1990 programme boundary: The Legacy RS arrived for Subaru's subsequent WRC programme and should not be described as an RX Turbo version.
Championship caveat: The RX Turbo did not claim any manufacturers' world title or outright WRC rally victory.

Driving Characteristics

The boxer layout kept much of the engine mass relatively low, while four-wheel drive provided traction in low-grip stages. However, placing the powertrain in the nose was not equivalent to the mid-engined balance of a Peugeot 205 T16; momentum transfer still needed managing under heavy braking and on rough crests.

The modest 1.8-litre turbo engine and changing competition transmissions meant available torque, boost and diff behaviour varied by build. There is no credible basis for asserting all RX Turbos were universally forgiving on every surface.

Safari results illustrate durability and preparation rather than overall WRC superiority: the sixth/seventh finish followed a high-attrition 1986 event and remained outside the overall podium. Driver/crew records and Group A class designation should accompany these claims.

Development & legacy

The RX Turbo bridges Subaru's early Leone rally experience and the later Legacy/Impreza world-championship era. Its genuine 1986 Safari sixth and seventh places are meaningful and checkable achievements; fictional outright podiums or retroactive Prodrive/WRX specifications are not.
