Mitsubishi Motors began manufacturing its "Delica" line of commercial passenger vans in 1969. The word "Delica" combined the words "delivery car," and depending on the export market, Mitsubishi would sell the Delica under a number of model names. From 1994 to 2006, the company sold this van as the L400 "Space Gear" model. In 1997, Mitsubishi slightly redesigned the L400 and continued producing that line until it replaced it in 2007 with the Delica D5.
Mitsubishi offered the L400 Delica with a number of engine and drivetrain options. Prospective buyers seeking a four-cylinder engine could choose from a 2.5-litre inline four or a 2.8-litre displacement turbocharged diesel. Those seeking a six-cylinder engine could opt for either a 2.4-litre, 12-valve engine or a 3.0-litre six that used four valves per cylinder, for a total of 24 valves. All of the L400 Delicas came equipped with Mitsubishi's INVECS-II4 four-speed automatic transmission, and prospective buyers could choose between an L400 with two-wheel or four-wheel drive.
The amount of horsepower and torque generated by the L400 depended on the engine installed in the vehicle. For instance, an L400 equipped with the 2.8-litre turbo diesel could generate 138hp at 4,000 revolutions per minute (rpm) and 231ft.-lbs. of torque at 2,000rpm while achieving a compression ratio of 21:1.
Mitsubishi offered the Delicas in a number of trim and body options that varied the dimensions of the L400. Mitsubishi made small cosmetic changes to the L400 in 1997 that slightly altered the overall dimensions of the subsequent L400s. During the production run, the length of a Delica L400 ranged from 180.9 to 200.2 inches with a wheelbase of 110.2 to 118.1 inches. The L400 also varied in height, from 73 to 81.5 inches, with all models having a width of 66.7 inches. An L400's weight would vary by body style and engine, varying from 3,700 to 2177kg.
