The sleek 1988 Voyage concept car was a “rolling laboratory” of technology. Its computer- controlled drivetrain automatically switched from rear-wheel drive to four-wheel drive when sensors determined slippage in the rear wheels, providing a 50/50 torque split from front to rear. Voyage was equipped with four-wheel-disc brakes with electronic anti-lock braking, four-wheel independent suspension and electronically controlled four-speed automatic transmission. Its orthopedically-designed seats included more than 20 pneumatic and mechanical adjustments, three memory positions, plus back and cushion heaters with cushion massage.

This luxury sedan had all-new computer-controlled all-wheel technology hidden under its streamlined body; the front axle was automatically engaged when rear-wheel slippage was detected. The Voyage was equipped with ABS, an electronically controlled five-speed automatic gearbox and a voice-activated telephone system. Its orthopedically-designed seats included more than 20 pneumatic and mechanical adjustments, three memory positions plus cushion massage. The Seville CTS adopted a number of the Voyage’s styling cues when introduced in 1991.
