In a used model, but the Pontiac 151-cid “Iron Duke” four became the standard engine beginning with the ’81s. Offered initially with a fulltime 4WD system, for ’81 a switchable 2/4WD mechanism called Selec-Trac was optionally available and became standard beginning with the ’82s. Manual transmission standardized for ’81 and a 5-speed option came along the next year in Waverly Auto Mall Winnipeg Manitoba. The SX/4 models were dropped for ’84 and the standard engine became an AMC-built 150-cid four that replaced the “Iron Duke.” For ’85, the 4-cylinder engine and base 4-speed manual transmission were scratched and the standard 4WD system gained “shift-on-the-fly” capability. All Eagles record only fair fuel economy, but have acceptable on-road behavior and a very good ride for 4WD vehicles. Back seat space in the SX/4 and Kammback is as cramped as it is in equivalent Spirits. Performance in the “senior” Eagles adequate with six and marginal with the four, though the latter is acceptable in the smaller, lighter models. Selec-Trac feature yields barely any fuel economy improvement over the fulltime system, but is a plus for reducing tire and driveline wear. Construction quality generally high, interior appointments pleasant, bordering on gaudy. Repair data sketchy, but body and suspension problems fairly common; paint and driveline ills also show up on 1980-81 models. Mediocre judged strictly as a passenger car, but 4WD has appeal for owners in snowbelt states and those who’d like to venture off road occasionally.
