The 1988 BMW M3 Group A is not merely a fast machine. It represents a golden era of European touring car competition. This specific chassis, M3 10820, was first delivered to France’s SDA race team. It was a stripped-down bare shell prepared for the rigorous demands of Group A modifications. Consequently, this car carries a remarkable pedigree from the outset, a true motorsport thoroughbred.
The Life of a French Touring Car Contender
The car began its racing life in the 1988 French Touring Car Championship. This was a critical testbed for the legendary E30 M3 platform. Shortly after, the car received a significant conversion. Therefore, it was adapted to the popular Supertouring specification. It then campaigned in the intense Championnat de France de Supertourisme from 1989 through 1991. The competition in this series was famously fierce and showcased Europe’s best drivers.
Spanish Championship Triumph and Privateer Years
In 1993, the car was cleverly reverted back to its original Group A-specifications. This change allowed Spanish driver Rafael Barrios to race it effectively. Barrios then helped secure the Marque Champion title for BMW. This was a significant achievement in the Campeonato de España de Turismos. Following this success, the M3 transitioned to private ownership in 1995. Alain Delaporte purchased the car from SDA Racing. He actively campaigned it in various French club races and challenging hill climbs.
Fabrice Combe acquired the M3 in 1999. He continued its life on the hill climb circuit for a brief period. Later that year, Pascal Chatenay took ownership. The E30 M3 platform has always been respected for its versatility. Its continued use in varied privateer events highlights this durability.
Restoration and Modern Racing Preparation
The early 2000s brought a period of necessary refurbishment. Following this extensive work, the car continued its active participation. It competed in regional and national hill climb events for several years. The current seller acquired the historic racer in 2008. Soon after, it was imported into the US via the UK.
Extensive Mechanical Overhaul for Performance
From 2009 to 2025, significant mechanical refurbishment was completed. Experts like Bill Watson of Road Rockets and Jim Froula of Racecraft performed key work. This comprehensive overhaul focused on preparing the car for its next chapter in competition. Attention to detail was paramount during this entire process.
The Group A-specification 2.5-liter S14 inline-four engine was fully rebuilt. Similarly, the modified Prodrive/Getrag 265 five-speed manual transmission received attention. This transmission features a robust dog-ring engagement and cryo-treated gears for strength. Furthermore, the limited-slip differential was completely rebuilt with 4.45:1 gearing.
The suspension and Brembo four-wheel disc brakes were also completely overhauled. The suspension now features Hyperco springs for precise handling. Driver-adjustable anti-roll bars provide tuning flexibility on the circuit. This blend of historic specification and modern component refinement is notable.
Engine Power and Racing Specifications
The 2.5-liter S14 inline-four engine underwent a major rebuild in June 2025. This work followed its failure during a break-in session. The engine was rebuilt to Group A specifications by Terry Tinney Performance Motors. This included boring and honing the block. Custom pistons and rings were also installed. The engine is now claimed to produce approximately 287 horsepower at the rear wheels. This is a formidable output for a naturally aspirated four-cylinder.
Race-Ready Exterior and Interior Details
The car is visually striking, finished in white with tri-color M stripes. Exterior features include a functional front splitter. An aerodynamic EVO-style rear spoiler aids downforce at speed. The 18-inch Speedline center-lock wheels are a bold, performance-focused choice. Inside, safety is paramount with a Matter roll cage and door bars. A single Sparco racing seat and OMP multi-point harness secure the driver. For safety, an AFFF foam fire-suppression system is also installed. A racing-focused ATL fuel cell completes the race-ready package.
The cockpit is finished in silver for a purposeful atmosphere. A microsuede-trimmed Sparco steering wheel faces the driver. Instrumentation includes a high-revving 10k-rpm Quartz tachometer. VDO auxiliary gauges monitor critical engine functions. Digital gauges in the center stack track brake temperature and bias.
Summary of the 1988 BMW M3 Group A
This 1988 BMW M3 Group A is a compelling example of a successful E30 M3 racer. Its competition pedigree spans the French Touring Car Championship and the Championnat de France de Supertourisme. It notably secured a Marque Champion title for BMW in Spain. Following a transition through various hill climb events, it underwent a meticulous mechanical refurbishment in the US. The heart of the car is a freshly rebuilt, high-output 2.5-liter Group A S14 engine. Accompanied by an FIA Historic Technical Passport, this M3 is prepared for its next owner to write a new chapter in its distinguished racing story.
