Mercury’s show vehicle for 1991 was the Mystique minivan that merged the practicality of a station wagon with a multipurpose luxury vehicle. The sleek-looking Mercury featured "T-drive," whereby the transversely mounted engine mated with the transmission in a way to send power to any or all wheels. Interior featured six-bucket seats and individually controlled TVs and VCRs mounted in the front seat backs. The Mystique concept bore no resemblance to the sedan of that name that would debut for 1995.
