Style first. Drive later.
Geneva, 2010: a liquid-silver four-door coupé that looked like the next CLS — and could be either a plug-in hybrid or a fuel cell, from the same platform.
Mercedes brought two stories to Geneva that March. One was design: a five-seat premium sedan with a coupe roofline, short overhangs and an upright star that already looked like the second-generation CLS. The other was architecture.
The F 800 Style introduced what Mercedes called a multi-drive platform — one body structure that could swallow either a plug-in hybrid or a compact fuel-cell stack without stealing cabin space. Designer Karim Habib shaped the skin; the engineers shaped the choice.
Chapter I
Pick your zero-emission day.
The plug-in hybrid paired a roughly 300-horsepower 3.5-liter V6 with a 109-horsepower electric motor ahead of a seven-speed automatic. A lithium-ion pack of more than 10 kWh under the rear seat promised about 18 miles of pure-electric range — technology Mercedes said was headed for the next S-Class.
The F-CELL variant used a 100 kW (136 hp) electric motor and the same compact fuel-cell stack destined for the B-Class F-CELL fleet. Range: nearly 375 miles on 5.2 kilograms of hydrogen, top speed limited to 180 km/h.
Both packages lived in the engine bay and chassis gaps. Downsizing every F-CELL component kept the front end compact enough that five adults still got a full cabin — the point of the multi-drive idea.
Locally emission-free mobility, Mercedes said, at the level of a premium automobile. The show stand called it BlueEFFICIENCY.
Plug-in Hybrid
3.5 L V6 + 109 hp motor · ~18 mi EV range · ~400 hp combined
F-CELL
100 kW fuel-cell electric · ~375 mi on 5.2 kg hydrogen
Chapter II
The CLS, one generation early.
At 15.5 feet, the F 800 Style sat between E-Class and S-Class — a “baby CLS” in the rumor mill, and in retrospect a clear dress rehearsal for the C218 CLS of 2010–11. Long wheelbase, short overhangs, that continuous roof arc: Gorden Wagener’s new design idiom, already production-ready.
The cabin previewed operating ideas that would define the next decade — a camera-assisted touchpad, a traffic-jam assistant for semi-automated crawling, and display concepts that treated the dashboard as software. The sliding rear doors were pure research theatre; the face was not.

Epilogue
The platform idea that stuck.
The second CLS arrived looking like a slightly tamed F 800. Plug-in hybrids reached the S-Class on schedule; the passenger-car fuel-cell path eventually narrowed. What endured was the multi-drive thesis itself — one architecture, several powertrains — which became how Mercedes (and everyone else) would build cars through the electrification decade. Style, in this case, was the delivery system for a structural argument.
