The 1997 Luxury Sedan Landscape: A Market at Its Peak
The late 1990s represented a golden era for luxury sedans, with German precision, Japanese refinement, and American innovation converging in a high-stakes battle for supremacy. According to Car and Driver’s 1997 comparison test, four models emerged as frontrunners: the BMW 540i, Mercedes-Benz E420, Infiniti Q45t, and Lexus LS400. Each brought distinct philosophies to the segment—from BMW’s driver-focused dynamism to Lexus’s uncompromising comfort.
A 1997 luxury sedan comparison test reveals the era's defining trade-offs between performance and comfort.
Head-to-Head: Performance, Comfort, and Value in 1997
The German Titans: BMW 540i vs. Mercedes-Benz E420
The BMW 540i arrived with a 4.0L V8 producing 282 hp, offering razor-sharp handling and a driver-centric cockpit that made it the enthusiast’s pick. Its six-speed manual transmission (optional) and taut suspension delivered engagement that few rivals could match. Meanwhile, the Mercedes-Benz E420 countered with a 4.2L V8 and a reputation for unparalleled refinement. Its air suspension and whisper-quiet cabin set a new standard for luxury, though critics noted its steering felt less communicative than the BMW’s.
The Japanese Contenders: Lexus LS400 and Infiniti Q45t
The Lexus LS400, already a benchmark for reliability and quietude, doubled down in 1997 with a 4.0L V8 and a focus on occupant comfort. Its 0-60 mph time of 7.5 seconds lagged behind the BMW’s 6.2-second sprint, but its 28 mpg highway rating and near-silent cabin made it a favorite among those prioritizing tranquility over thrills. The Infiniti Q45t, with its sport-tuned suspension and 278 hp V8, aimed to bridge the gap between performance and luxury. However, its handling was criticized as overly firm, and its interior materials felt less premium than the German offerings.
Key Findings: What the 1997 Test Revealed
Power and Performance
- BMW 540i: 282 hp, 0-60 mph in 6.2s, best-in-class handling.
- Mercedes-Benz E420: 275 hp, 0-60 mph in 6.8s, superior ride comfort.
- Lexus LS400: 290 hp, 0-60 mph in 7.5s, best fuel economy (28 mpg highway).
- Infiniti Q45t: 278 hp, 0-60 mph in 7.0s, sport-tuned suspension but criticized for ride harshness.
Luxury and Refinement
The Mercedes-Benz E420 and Lexus LS400 stood out for their cabin materials and noise isolation. The E420’s optional air suspension and wood/leather appointments exuded opulence, while the LS400’s near-flawless NVH (noise, vibration, harshness) levels set a benchmark that many automakers still strive to meet today. The BMW 540i, though luxurious by 1997 standards, prioritized driving dynamics over plushness, with firmer seats and a more utilitarian interior.
Value Proposition
At launch, the Lexus LS400 carried a base price of ~$50,000, undercutting the BMW 540i (~$55,000) and Mercedes-Benz E420 (~$60,000). The Infiniti Q45t, priced at ~$48,000, offered strong value but struggled to justify its premium over mainstream sedans like the Toyota Avalon. Resale values in 2026 confirm the LS400’s enduring appeal, with clean examples commanding premiums of 20-30% over original MSRP.
Legacy and Impact: How These Sedans Shaped the Future
The 1997 comparison test underscored a pivotal moment in automotive history: the end of an era where raw performance and mechanical sophistication still mattered as much as digital amenities. The Lexus LS400’s success proved that Japanese brands could dominate luxury without sacrificing reliability, while the BMW 540i’s driver-focused ethos foreshadowed the rise of the "driver’s car" in the 2000s. Mercedes-Benz, meanwhile, doubled down on comfort, a strategy that would later evolve into the modern S-Class’ emphasis on rear-seat luxury.
Today, these sedans are celebrated as icons of 1990s automotive design. The Lexus LS400’s reliability and the BMW 540i’s driving dynamics have ensured their place in enthusiast garages, while the Mercedes-Benz E420 and Infiniti Q45t remain cult favorites among collectors. Their legacy lives on in modern flagships like the Lexus LS 500, BMW 7 Series, and Mercedes-Benz E-Class—each carrying forward the DNA of their 1997 forebears.
The Lexus LS400’s near-silent cabin and Mercedes-Benz E420’s air suspension redefined luxury expectations in the 1990s.
Final Verdict: Which 1997 Sedan Won the Test?
While each sedan excelled in different areas, the Lexus LS400 emerged as the overall winner for its blend of reliability, comfort, and value. The BMW 540i claimed the enthusiast’s vote for its driving dynamics, while the Mercedes-Benz E420 set new standards for luxury refinement. The Infiniti Q45t, though ambitious, fell short due to its compromised ride quality and interior ambiance.
For collectors and enthusiasts today, these sedans represent more than just transportation—they’re time capsules of an era when automotive excellence was measured in cubic inches, hand-stitched leather, and the hum of a naturally aspirated V8. Whether you prioritize performance, comfort, or value, the 1997 luxury sedan showdown offers timeless lessons in what makes a car truly great.
