Development and testing began in 1999 under the joint direction of Hyundai World Rally Team and MSD. The Accent WRC was built on a steel monocoque chassis powered by a 1,998 cc inline-four turbocharged engine, cast in aluminium and mounted transversely at the front. Power output was 300 bhp at 5,300 rpm and 520 Nm of torque at 3,500 rpm, managed through a Garrett/Allied Signal TR30R turbocharger and a Hyundai/Pectel engine management system. Drive went to all four wheels through a six-speed X-Trac non-synchronised sequential gearbox; the front and centre differentials were electronically controlled while the rear differential was a mechanical self-locking unit. Torque distribution was 50/50 front to rear. Suspension was independent McPherson struts with lower wishbones at both ends, with cabin-adjustable anti-roll bars. Braking was handled by 368 mm vented discs with six-pot water-cooled aluminium calipers at the front and 304 mm vented discs with four-pot calipers at the rear. The car ran on 8 × 18-inch wheels shod with Michelin 20×65/18 tyres and met the FIA homologation minimum weight of 1,230 kg. Dimensions were 4,200 mm long, 1,770 mm wide, and 1,332 mm tall on a 2,440 mm wheelbase.
The Accent WRC made its competitive debut at the 2000 Rally Sweden. Over its three-season WRC campaign the car contested 48 events without achieving a podium; its best result in any WRC event was fourth place.
The second evolution, the Accent WRC2, introduced revised aerodynamics, an active front differential, longer suspension travel, and improved suspension top mounts. Reliability improvements were the primary focus of the revision, as the car's best result remained unchanged. The third generation, the Accent WRC3, brought new dampers and revised engine internals and made its debut at the 2002 Tour de Corse.
Hyundai assembled experienced international drivers throughout the programme. Four-time world champion Juha Kankkunen campaigned the car, as did Kenneth Eriksson, a former Group A champion and Subaru race winner, and Alister McRae, a former British Rally Champion. Both Kankkunen and Eriksson were competing in the latter stages of their careers. Belgian driver Freddy Loix and Armin Schwarz — winner of the 1991 Rally Catalunya — were also closely associated with the Accent programme across its lifespan. That Hyundai could attract drivers of this calibre underlined the credibility of the programme even if results remained elusive.
Budget pressures progressively curtailed development through the 2003 season. In September 2003 Hyundai announced its withdrawal from the World Rally Championship. The manufacturer returned to WRC competition more than a decade later, entering in 2014 with the Hyundai i20 WRC — a purpose-built rally car unveiled at the 2012 Paris Motor Show and developed by the newly established Hyundai Motorsport GmbH subsidiary based in Alzenau, Germany. The Accent WRC is considered the first chapter of what became a substantially more successful WRC presence, ultimately including manufacturer championship victories.
