Mitsubishi Lancer Evolution IV–VI

Overview Specs Highlights Characteristics

Overview

When World Rally Car rules arrived in 1997, Mitsubishi deliberately kept its Group A-derived Lancer Evolution factory cars instead of launching a new WRC-formula model. The result was an unusually direct connection between homologated road cars and championship competition hardware.

The Evolution IV (1997 works season) was based on a redesigned Lancer platform; the Evolution V widened it in 1998, and the Evolution VI refined aerodynamic and cooling hardware for 1999. Each was a competition development, not one mechanically identical car under three badges.

Technical Specs & Innovations

  • Regulatory category: Group A factory cars competing in WRC against newly introduced World Rally Cars (1997–99).
  • Engine family: Mitsubishi 4G63, transverse DOHC turbocharged 16-valve inline-four.
  • Displacement: 1,997 cc in Mitsubishi's factory 1997–99 WRC specification sheets.
  • 1997 Evo IV packaging: The 4G63 was rotated 180° relative to Evo III and four-wheel-drive components were redesigned to fit the new shell.
  • Turbo system: Turbocharger, charge cooling and competition engine control operated within Group A intake-restrictor regulations.
  • Period output tables: Mitsubishi lists 290 PS for its representative 1997 Evo IV and 1998 Evo V WRC figures; power changed with tune and published references.
  • Differentials: Four-wheel-drive mechanicals with ongoing electronically controlled active centre differential and clutch-capacity development in 1998.
  • Production AYC caution: Active Yaw Control on the production Evolution IV/V rear driveline is distinct from the Group A works centre-differential hardware; the names do not establish identical rally installations.
  • Evolution IV width: 1,690 mm in Mitsubishi's 1997 works specification.
  • Evolution V width: 1,770 mm in Mitsubishi's 1998 works specification; the production homologation body was widened to keep pace with 1,770 mm WRC rivals.
  • Evolution V suspension: Wider track and revised suspension and brake packages; competition configurations changed by rally surface.
  • Evolution VI aerodynamics: Reworked bumper and two-stage rear wing; FIA required blocking the lower rear-wing opening to meet regulations.
  • 1997 rule minimum mass: 1,230 kg for the relevant Group A and World Rally Car turbo class; this is a regulatory minimum, not a certified kerb weight for all cars.
  • Construction: Production-derived four-door rally monocoque with competition safety cage, reinforcement, and surface-specific brake, tyre and suspension systems.

Model-specific evolution: IV (1997) introduced the reversed engine/transmission architecture; V (1998) gained the wider 1,770 mm homologated platform and developed centre differential; VI (1999) focused on aerodynamics and other refinements. Production car 280 PS marketing numbers should not be used as works dyno figures.

Chronology: Mitsubishi also developed the Evolution VI Tommi Mäkinen Edition road car around 1999–2000. It should not be described as a separate car that won the 1999 title simply because it carries Mäkinen's name.

🏆 Competitive Highlights

  • 1997: Tommi Mäkinen and Seppo Harjanne retained the WRC drivers' championship in the Evolution IV. Mitsubishi remained Group A while Subaru and Ford fielded WRC-formula cars.
  • 1998: Mäkinen's third consecutive drivers' championship and Richard Burns/Robert Reid's wins helped Mitsubishi secure its first WRC manufacturers' championship.
  • 1998 Rally Catalunya: The wide-body Evolution V made its works debut; Mitsubishi had opened the season in Evo IV machinery.
  • 1998 Rally Great Britain: Burns and Reid won the final event, clinching the manufacturers' crown, as Carlos Sainz's Toyota stopped late and Mäkinen retained the drivers' crown.
  • 1999: The works Evolution VI took victories including Monte Carlo, Sweden and New Zealand as Mäkinen earned his fourth consecutive drivers' title (1996–99).
  • 1999 manufacturers: Toyota, rather than Mitsubishi, won the manufacturers' championship; do not assign that title to the Evolution VI.

Driving Characteristics

The wider Evo V platform directly addressed Mitsubishi's reported high-speed stability deficit against World Rally Cars with wider tracks. Active centre-differential calibration and suspension development changed how traction could be deployed on gravel, snow and asphalt.

While the 4G63 family persisted, the Evo IV's 180° engine rotation and AWD redesign meant it was not simply the Evo III powertrain carried forward unchanged. Its mechanical evolution explains its competitiveness under Group A rules.

Development & legacy

These cars show that a continually homologated production-based platform could beat newer World Rally Car designs. They delivered three consecutive drivers' titles in this period plus Mitsubishi's 1998 manufacturers' title, but the technical developments belong to specific versions and seasons.
