Mitsubishi Lancer Evolution Evolution I CD9A
The Mitsubishi Lancer Evolution I, designated CD9A, emerged in 1992 as a homologation special designed to make the humble Lancer competitive in World Rally Championship Group A competition. What began as a limited-production exercise to meet FIA regulations would evolve into one of the most iconic performance car lineages in automotive history.
At the heart of the Evolution I sat the 4G63T — a 2.0-liter turbocharged inline-four that would become perhaps the most famous four-cylinder engine in Japanese performance car history. In its initial Evolution specification, the iron-block, aluminum-head engine produced 247 horsepower (at the self-imposed Japanese industry limit of 280 PS, though actual output was widely believed to exceed this figure) and 228 lb-ft of torque. The TD05H turbocharger provided strong mid-range response, and the engine's oversquare bore-and-stroke dimensions allowed it to rev freely.
The Evolution I's all-wheel-drive system was a viscous-coupling-based arrangement that sent power to all four wheels through a center differential. While simpler than the active differentials that would appear in later Evolutions, the system provided excellent traction and predictable handling characteristics. The front wheels received the majority of torque under normal conditions, with the viscous coupling progressively engaging the rear axle as conditions demanded.
Mitsubishi planned to build just 2,500 units to meet homologation requirements, but demand was so intense that production was doubled to 5,000. Even this increased run sold out almost immediately, with many buyers paying premiums over the already modest list price. The Japanese public recognized that the Evolution offered supercar-rivaling performance at a fraction of the cost.
The bodywork was outwardly similar to the standard Lancer, with the additions of a front lip spoiler, rear wing, fog lamps, and subtle body extensions to accommodate wider tires. The restrained appearance belied the car's extraordinary capability — a characteristic that would become a hallmark of the Evolution series.
In competition, the Evolution I immediately proved its worth. Mitsubishi's WRC team used the car as the basis for their Group A rally car, and the Evolution's combination of light weight, strong power delivery, and robust mechanicals made it instantly competitive. The rally program's success drove enormous interest in the road cars, establishing a virtuous cycle of motorsport success and commercial demand that would sustain the Evolution nameplate for over two decades.
Today, the Evolution I is recognized as the genesis of a legend. Clean, unmodified examples are extraordinarily rare and command premium prices, particularly from collectors who understand the historical significance of this first chapter in the Evolution story.
Finding a genuine Evolution I is extremely challenging, as virtually all were sold in Japan. Import history and documentation are critical. Verify the chassis number begins with CD9A. The 4G63T engine is robust but inspect for head gasket issues, turbo shaft play, and oil leaks from the rear main seal. Check the viscous coupling AWD system for proper engagement. Rust is a concern on all examples, particularly in the sills, rear wheel arches, and floor pans. Many Evo I examples were used hard in motorsport or modified extensively — original, unmodified cars are exceptionally rare and valuable. Service records from Japanese dealers add significant value.
Built at Mitsubishi's Okazaki plant in Aichi Prefecture. The Evolution I was based on the CD Lancer sedan platform with extensive modifications to the engine, drivetrain, suspension, and brakes. Initially planned at 2,500 units for homologation, production was doubled to 5,000 due to overwhelming demand. Sold exclusively in Japan — no official exports. The car was offered in limited colors and with minimal optional equipment to keep weight and cost down.
