Chrysler's A604 (41TE) "Ultradrive" transversely mounted automatic, it became the A606 (also known as 42LE). By 1990, it was decided that the new technologically advanced car would need a new technologically advanced engine to power it. Until that time, the only engine confirmed for use was Chrysler's 3.3 L pushrod V6. The 3.3 L engine's 60° block was bored out to 3.5 L, while the pushrod-actuated valves were replaced with SOHC cylinder heads with four valves per cylinder, creating an advanced 3.5 L V6. The appearance, still based on the cab forward exterior design of the 1987 Lamborghini Portofino concept, with its aerodynamic shape, made for little wind noise inside this large car. The engineering and sleek styling gives the Vision a low drag coefficient (0.31), on par with the Porsche 997. Without badges, the Vision could easily pass as a (first-generation) Concorde. The main difference between the two are the taillight clusters. Like the European sedans it was marketed to compete against, the Vision incorporates rear amber turn signals over the Concorde's red ones. Neither does the Vision have the Concorde's faux rear lightbar between the taillights. While the two cars share headlights, the Vision's grille is smaller and, separated by its prominent center badge, has been likened to the appearance of "nostrils." The interior of the Vision is nearly identical to the Concorde, the biggest difference being the absence of the Concorde's faux wood trim and steering wheel emblem. Unlike the Vision, the Concorde never offered the AutoStick option. Marketed as a sports sedan, the Vision offered only bucket seats with a console, never the split bench with column shift. The Vision featured a monochromatic design inside and out, with no brand or model badge on the doors (as found on the Concorde), and available aluminum wheels with a simple design. The single color motif was more pronounced on models without the grey lower body trim paint scheme. In keeping with its high-performance image, the Vision was the only LH sedan to come standard with "touring" suspension. "Performance" suspension was an available option on the Vision. The upscale TSi model featured leather-trimmed seats, 8-way power seats for both the driver and front passenger, leather-wrapped steering wheel, leather shift knob, cloth door inserts, rear seat vents, center rear armrest, and personal reading lamps. Power windows and central door locks were standard for both trims, as were dual airbags, with
