The Airtrek was first introduced to the Japanese market on 20 June 2001, priced from ¥1.7–2.3 million.
It offered a choice of either a 126 PS (93 kW) 4G63 2.0 L or a 139 PS (102 kW) 4G64 2.4 L GDI, mated to a standard INVECS-II 4-speed semi-automatic transmission.
Both front- and four-wheel drive were available.
The four-wheel drive version uses open differentials for the front and rear axles, with a viscous coupling unit for the center differential.
A high performance model, called the Turbo R, was introduced in 2002 and used a detuned version of the Lancer Evolution's 4G63T 2.0 L I4 turbo.
The engine produced 240 PS (180 kW) and 343 N⋅m (253 lb⋅ft), although in export markets the Outlander version's output was reduced to 202 PS (149 kW) and 303 N⋅m (223 lb⋅ft).
The return of four-cylinder engines under 2.0 liters offered Japanese buyers a vehicle that was in compliance with Japanese regulations concerning exterior dimensions and engine displacement, however, the exterior dimensions exceed Japanese regulations for the "compact" designation.

The Outlander arrived in 2003 in North America, replacing the Mitsubishi Montero Sport, with a modified front grille and headlights which increased the overall length by approximately 130 millimetres (5.1 in), and the two models were manufactured in parallel thereafter.
It shared its platform with the Mitsubishi Grandis, also introduced in 2003.
A version of the 4G64 powerplant was offered first, while a 4G69 2.4 L SOHC MIVEC I4 producing 120 kW (160 PS) and 220 N⋅m (160 lb⋅ft), and the turbocharged 4G63T appeared in 2004.
All had the option of front- or four-wheel drive.

In several South American markets it was known as the Montero Outlander, to benefit from an association with the strong-selling Mitsubishi Montero Sport.
