The Alluring Mystery of the 'Floating Window' Door in Car Design - Floating windows or suicide doors: The debate around right-hinged rear doors
The question of floating windows versus suicide doors, also known as right-hinged rear doors, sparks passionate debate among automotive purists and design enthusiasts. Both configurations offer distinct benefits that appeal to different tastes, and each presents unique engineering challenges.
Suicide doors were common in luxury brands of the 1950s and 60s, such as Cadillacs and Mercedes-Benz. They conveyed an aura of bespoke craftsmanship and prestige service, evoking images of chauffeured rides. But some argue they compromise functional entry/exit compared to doors that open against the vehicle. Slamming suicide doors in tight spaces also risks damage to adjacent vehicles.
Meanwhile, floating windows are seen by some as the more driver-centric solution that prioritizes ingress/egress without obstacles. They also optimize structural stiffness by attaching both front and rear doors directly to the beltline for increased safety. But floating windows are also criticized for lacking the vintage charm of yesteryear's suicide doors.
Ultimately, the choice comes down to individual preferences between aesthetics and usability. Salvatore, a vintage car collector, notes the "theatrics and flair for the dramatic" imbued by suicide doors on his restored Mercedes reminds him of a bygone era. Meanwhile, Sandra, an avid track day driver, sees unrestricted access via flying buttresses on her Lotus Elise as crucial to fast driver changes between sessions.
New technologies have revived discussion on improving each configuration.

The Alluring Mystery of the 'Floating Window' Door in Car Design - Customizing with a custom floating window: Aftermarket upgrades and how-tos
For dedicated enthusiasts willing to invest time and money, customizing a stock vehicle with an aftermarket floating window conversion can be deeply rewarding. This extensive modification allows creating a bespoke appearance while also teaching invaluable skills.
Full floating window conversions require advanced metalworking expertise and attention to detail. The factory welds attaching the door to the body must be cut with precision plasma tools before fabricators can graft in fresh door frames and hand-form new window openings. Brandon, who customized his Nissan 300ZX, says this intimidating metal surgery took 3 weeks of practicing on scrap panels before attempting the final work.
The glass itself poses challenges too. Off-the-shelf solutions rarely fit aftermarket floating window frames precisely. This is where artisans like Eduardo enter the equation. His shop in Pomona, California specializes in custom-cutting and shaping automotive glass supplied as oversized blanks. Eduardo ensures the final product has tight tolerances for flush mounting and watertight seals. For Brandon's 300ZX, the curved quarter window alone took Eduardo 12 painstaking hours over 2 days to grind and polish.
But perseverance through the long process yields exciting rewards. Owners describe driving their customized floating window vehicles as transformative, with surround views creating an exhilarating sense of freedom. Brandon was brought to tears the first time he opened the doors on his finished 300ZX, saying it was better than he ever imagined. For him, the scrutiny to detail was worth it.
For those lacking metalworking skills, appearance modifications like snap-in window louvers offer easier customization. Companies like RELAX make louver sets that mount into existing door frames without permanent alteration. This provides the floating window aesthetic when doors are closed. While not authentic conversions, louvers sufficiently capture the look for casual hobbyists.
The Alluring Mystery of the 'Floating Window' Door in Car Design - Floating windows on electric vehicles: Battery placement problems and solutions explored
The transition to electric vehicles presents both opportunities and challenges when implementing a floating window design. While the lack of a bulky engine and transmission liberates designers to extend cabins for a seamless glasshouse flow, the placement of battery packs becomes a complex puzzle. How EV makers creatively integrate batteries while retaining the floating window aesthetic is an illuminating case study in automotive design.
The core predicament is finding space for batteries that typically lie underfloor or in the rear. But the floating window look demands as little interruption along the beltline as possible. This forced designers to get clever with battery configurations early on. The original Tesla Roadster stacked cells behind seats, allowing a continuous glass roof for its targa top appearance. However, such a layout reduced cargo room and overall energy density.
Next came the idea of a rear "spine" pioneered on the BMW i3. Concentrating cells centrally between rear wheels maintained even weight distribution and freed up front and rear crumple zones. But this divided the cabin in half, obstructing the desired unbroken vista. The Porsche Taycan built on the spine approach but tapered the pack thinner above wheel arches to allow a single wraparound rear window panel. Critics, however, argued this compromised interior space.
Most recently, underfloor configurations have enabled greater progress toward optimized floating windows. The low, flat chassis of the Audi e-tron GT means its 95 kWh pack can hide completely out of sight below the cabin. The vehicle"s arching shoulder line and fastback silhouette remain visually unencumbered. At the bleeding edge, startups like Lucid Motors have developed miniaturized drive units to fit batteries entirely within chassis rails. By eliminating a separate underfloor pack, their Air sedan achieves a genuinely full-width floating window vista.
