# 1998 Mid-Size Luxury Sedans: A Snapshot of Automotive Ambition
Car and Driver's 1998 mid-size luxury sedan comparison test captured a pivotal moment in the segment. This collection of vehicles represented manufacturers' competing visions for what affluent drivers wanted: sportier handling, advanced technology, refined interiors, or a blend of all three.
The field was genuinely diverse. The Mercedes-Benz C280 arrived as the segment's benchmark, offering German engineering credibility and a naturally aspirated inline-six engine. The Lexus GS300 brought Japanese precision and reliability into direct competition with established European marques. The Audi A6 represented the avant-garde approach, with available Quattro all-wheel drive and minimalist interior design. Volvo's S70 GLT emphasized safety and comfort over sportiness. Saab's 9-5 SE stood apart with its distinctive cockpit-style interior and turbocharged power. Cadillac's Catera marked General Motors' effort to recapture luxury market share with European-influenced handling. The Mazda Millenia S, arguably the most unconventional entry, offered accessible luxury with Mazda's Miller Cycle engine technology.
This test reflected where the market stood in 1998. Luxury meant different things to different buyers. Some wanted badge prestige. Others prioritized technology adoption. Performance enthusiasts sought handling credentials. Reliability-focused buyers gravitated toward Toyota's Lexus division. The comparison format forced head-to-head evaluation across attributes: acceleration, braking, handling, interior materials, ergonomic logic, trunk space, and perceived value.
The 1998 model year itself marked transitional territory. V-6 engines dominated the segment, though some models offered turbocharged four-cylinder or smaller V-8 alternatives. Five-speed automatics were becoming standard. Electronic power steering appeared on some vehicles but not others. Integrated navigation systems remained rare and expensive. Xenon headlights surfaced as a luxury differentiator. Dual-zone climate control had moved from gimmick to expected feature.
By 1998 standards, the C280 and A6 represented the dynamic-driving pole. The GS300 embodied Japanese reliability philosophy. The S70 prioritized occupant protection. Saab chased individualism. Cadillac pursued American luxury's new identity. Mazda attempted something different entirely. Each strategy reflected manufacturer DNA and market positioning.
What matters historically is that this comparison captured the last moment before several industry upheavals. The Saab brand's trajectory toward irrelevance was already set. Cadillac's Catera represented a misguided attempt that would soon be abandoned in favor of the CTS. The Millenia would vanish within years as Mazda refocused on volume segments. Meanwhile, Audi, Mercedes, Lexus, and Volvo would strengthen their positions through the 2000s, though each faced different challenges.
The photography itself documents design languages that have aged unevenly. The C280's angular simplicity survives stylistically. The S70's curvaceous form looks dated. The GS300's understated elegance has aged better than its competitors. The Saab's distinctive character feels lost now that the brand is gone.
For automotive historians, this test offers a window into consumer choice logic circa 1998. Buyers evaluated reliability ratings from J.D. Power. They considered resale value projections. They drove test vehicles to gauge steering feel and seat comfort. Digital infotainment was emerging but not yet dominant in purchase decisions. Brand heritage and warranty support mattered more than they would a decade later, when technology became the primary differentiation vector.
