1999 Subaru-Prodrive P25

Subaru’s rise in the World Rally Championship began with the Legacy RS, developed in collaboration with Prodrive, before the smaller and more agile Impreza was introduced as Subaru’s main rally car during the 1993 season. From that point, in successive Group A and World Rally Car evolutions, the Impreza would represent Subaru in the World Rally Championship until the manufacturer’s withdrawal at the end of 2008. The Subaru Impreza WRC was the World Rally Car developed for the Subaru World Rally Team by Prodrive, following the introduction of the new World Rally Car regulations for the 1997 FIA World Rally Championship. It replaced the earlier Group A-based Impreza 555 as Subaru’s front-line rally car and marked a new phase in the technical and sporting evolution of the Impreza platform. Based on the GC8-generation Impreza, the WRC version was designed around the greater freedom allowed by the new regulations, which no longer required the competition car to correspond as closely to a mass-produced homologation model as under Group A rules. The result was a purpose-built rally car retaining the Impreza’s fundamental identity: a compact bodyshell, a front-mounted turbocharged flat-four engine, permanent four-wheel drive and a layout ideally suited to loose-surface competition. The first Impreza World Rally Car appeared in 1997 in two-door coupé form. Wider bodywork, increased suspension travel and a more specialised chassis and drivetrain package made it one of the defining cars of the early World Rally Car era. In its debut season, the Impreza WRC immediately proved highly competitive, contributing to Subaru’s third consecutive Manufacturers’ title in the World Rally Championship. Through successive developments from 1997 to 2000, the Impreza WRC became closely associated with drivers such as Colin McRae, Richard Burns, Piero Liatti, Kenneth Eriksson and Juha Kankkunen. Its combination of distinctive engineering, compact proportions and blue-and-yellow works livery made it one of the most recognisable rally cars of its period, and one of the key reference points of the first generation of World Rally Cars. The Impreza remained Subaru’s World Rally Championship model through later four-door generations, continuing to compete at works level until 2008 and leaving a lasting identity as one of the most emblematic rally cars of the modern era.

The first-generation Subaru Impreza WRX was the road-going performance version of the GC8-generation Impreza, introduced in the early 1990s and developed around Subaru’s established technical identity: a compact bodyshell, a turbocharged horizontally opposed four-cylinder engine and all-wheel drive. In two-door form, the GC8 Impreza provided one of the most recognisable shapes in Subaru history, closely linked to the marque’s rise in international rallying and to the visual identity of the blue works cars developed with Prodrive. Although the Impreza WRX was a production road car, its architecture formed the basis from which Subaru’s rally programme developed. The earlier Group A Impreza 555 remained closely related to the road-car platform, while the later Impreza WRC, introduced in 1997 under the new World Rally Car regulations, used the two-door GC8 silhouette as the starting point for a purpose-built works rally car. In this sense, the two-door Impreza WRX stands at the centre of Subaru’s late-1990s performance identity: it was the road-car foundation from which the rally image was built, and the body architecture to which later reinterpretations would return. This distinction is important in the case of the Prodrive P25. The most celebrated road-going expression of this same visual and cultural world was the Subaru Impreza 22B STi. Produced in limited numbers in 1998, the 22B translated the image of the wide-bodied two-door Impreza WRC into a factory-built road car and became one of the most desirable turbocharged all-wheel-drive cars of its era. Prodrive itself identified the 22B as the road car inspired by the two-door Impreza WRC, with 424 examples produced and a lasting cult status. The Prodrive P25 was not built from an original works Impreza WRC, nor from a Subaru Impreza 22B STi. Prodrive specified that each P25 would be built around an original two-door Impreza WRX chassis, described as the same chassis type used in the first Impreza WRC, but reimagined with reduced weight, greater power and modern vehicle dynamics. Thus, the two-door Impreza WRX GC8 provides the material and architectural reference for the P25, while the 22B STi provides its closest road-going cultural precedent.

The Subaru Impreza with chassis no. GC8-079046 is a Prodrive P25 model. It was built in 2023 and is the 19th of a limited series of 25 built by Prodrive itself. The P25 model was built around an original two-door Subaru Impreza WRX chassis, but its visual and cultural identity refers to the 1997 Subaru Impreza WRC and to the road-going 22B STi that the WRC inspired. Introduced at the Goodwood Festival of Speed in June 2022, the P25 was conceived by Prodrive as a modern reinterpretation of the iconic blue Subaru Impreza, marking twenty-five years since the debut of the two-door Impreza World Rally Car. David Richards, Prodrive chairman, described the project as a reimagining of what that car could have become using contemporary technology and materials. Rather than a restored period rally car or a direct replica, the P25 was developed as a new, limited-production Prodrive model. Only 25 cars were planned, each using an original two-door Impreza WRX chassis at its core and assembled by Prodrive at its headquarters in Banbury, UK. The car was conceived as road registered, but with a level of engineering and performance deliberately rooted in Prodrive’s World Rally Championship experience. The P25 combined the proportions and emotional reference of the late-1990s Impreza with modern materials and mechanical development. Carbon-composite panels were used extensively to reduce weight in boot, bonnet, roof, sills, door mirrors, front and rear quarters, WRC style rear wing and bumpers. The powertrain was based on a 2.5-litre Subaru boxer engine totally re-engineered by Prodrive’s powertrain team with bespoke internal components, including new cylinder liners, pistons, con rods, and a valve train with variable cam timing. A Garrett performance road turbo is matched to a high performance intercooler and airbox and an Akrapovič titanium and stainless steel racing exhaust system is fitted. The powertrain producing more than 400 hp and over 61 kgm of torque. This was combined with four-wheel drive, a six-speed sequential gearbox with semi-automatic paddle shift, WRC-derived launch control, anti-lag and an adjustable active centre differential and limited-slip differentials front and rear. McPherson strut suspension has been retained but reworked and fully adjustable. Stopping is provided by AP Racing brakes. The cockpit combined modern instrumentation with rally-derived controls, including a full-width high-definition display with data logging, selectable throttle and engine maps, and anti-lag adjustment. It also featured a WRC-style fly-off hydraulic handbrake. The interior recreates an authentic late 1990s Impreza interior using a combination of leather, alcantara and carbon trim. The design and engineering links to the original Impreza WRC were also personal and historical. Peter Stevens, who styled the original 1997 Impreza WRC, restyled a number of features of the P25, working with the Prodrive engineering team overseen by David Lapworth, the technical director responsible for developing the first Impreza WRC twenty-five years earlier. Chassis GC8-079046 was specified with the optional rear-seat delete and partial safety cage, replacing the standard four-seat configuration. It was UK road registered on 1 December 2023 with registration P25TYO, in the name of Prodrive Motorsport, before final purchase settlement in March 2024 and delivery presentation at Prodrive on 10 April 2024. It subsequently appeared at the Japanese Car Meeting at Misano World Circuit Marco Simoncelli on 1–2 May 2024 and at the NAB Heritage “Leg 1 Colle d’Oggia” event held in conjunction with the 13th Rally Valle Imperiesi in November 2024.
