Every Tracker holds a 1.6-liter overhead-cam 4-cylinder engine, which started at 80 horsepower. A more potent version, with four valves per cylinder and rated at 95 horsepower, went into California Trackers in 1994, all 4-wheel drives in '95, and all models the next year. A 5-speed manual gearbox was standard; 3-speed automatic transmission optional. On-demand, part-time 4-wheel drive went into all Trackers at first, with a floor-mounted transfer case. Manual-locking front hubs have to be adjusted by hand from outside the vehicle before 4-wheel drive can be engaged. LSi Trackers adopted automatic-locking hubs in 1991. A new 4-speed automatic transmission was available for the 5-door wagon in '96.
