Overengineered German luxury cars: S-Class, 7 Series, A8 and beyond

Explore the allure and cost of overengineered German luxury cars—Mercedes S-Class, BMW 7 Series, Audi A8, VW Phaeton—where brilliance meets costly upkeep.

There’s a fine line between brilliance and engineering obsession—and Germany’s automakers have walked it for decades. These machines weren’t built for common sense so much as to persuade physics to back down.

The Mercedes-Benz S-Class W140 embodied the ethos of building the best, come what may: double glazing, soft-close doors, hydraulic systems and miles of wiring. The ride felt close to perfect. The invoice for the hydraulic suspension and electronics did, too. In response, the BMW 7 Series E65 became a manifesto of progress at any cost: the first iDrive, proactive electronics, intricate underpinnings. It leapt ahead of its time, but it also made drivers learn how to adjust their own climate through on-screen menus. Audi’s A8 D2 brought an aluminum spaceframe to the luxury class—lighter, stiffer, and enough to unsettle body shops after even a gentle bumper tap.

The Volkswagen Phaeton was Ferdinand Piëch’s ego project: cabin climate stable at 50°C at 300 km/h, a W12, air suspension and hundreds of sensors. As quiet as a cathedral and priced like one, it remained a car few really wanted—a VW with S-Class ambitions. The BMW 8 Series E31 was a space-age grand tourer with a V12, a drive-by-wire throttle and active kinematics: beauty and complexity that later translate into hours and money at the service bay. The Mercedes-Benz CL 600 C216 felt like a polite apocalypse: a biturbo V12 and Active Body Control that delivered weightless composure on the move—and five-figure bills as the hydraulics grew old.

The takeaway is straightforward: these cars serve up sensations you rarely find—hushed cabins, velvety motion, and ironclad stability at speed. Yet perfectionism demands a price, one often paid by the second and third owners. Admire them for what they set out to be—engineering manifestos—and approach any purchase with a cool head and a warm wallet. Their allure still feels hard to replicate.
