RARE ALL-WHEEL DRIVE
All-Wheel Drive (E-4WD) Aerostar 1996
Ford Aerostar family was Introduced in 1990 and offered until the end of production in 1997, Ford offered an electronically controlled four-wheel drive option on XLT and Eddie Bauer models. The option, called E-4WD, standing for Electronic 4-Wheel Drive, was more specifically an all-wheel drive system. With all-wheel drive, the 160 hp (119 kW) 4.0L Cologne V6 was standard equipment.
This system differed from other four-wheel-drive Ford vehicles of the time in that it engaged when it detected rear wheel spin, powering the front wheels automatically with no driver input required. Another difference is that the Aerostar's unique Dana TC28 transfer case employed a true center differential, though this center differential was regulated by an electronically controlled electro-magnetic clutch; this means that all four wheels are essentially powered at all times.
