Actually you are right, it is based on the SL55
THE FISKER COACHBUILD 2006 TRAMONTO IS A SCULPTED STATEMENT OF
EXOTIC OPEN-AIR MOTORING. Beneath the skin, the engineering
excellence of what its base architecture once was a Mercedes-Benz
SL55 AMG remains. The vast array of Mercedes-Benz finest
technological innovations, from the powerretractable hardtop to
Active Body Control (ABC), remains untouched, as do safety systems,
including crumple zones and airbags.
At the same time, the TRAMONTO has become something much more, and
the differences go
beyond what meets the eye. How far beyond is up to you: engine,
brake and exhaust-system
upgrades are available as are 0-60 times of 3.6 seconds and a top
speed of 202 mph. At the touch of a button on the console or the
remote locking device, the power-retractable hardtop transforms the
two-seat TRAMONTO from a coupe to roadster in just 16 seconds. And
even with the hardtop retracted, the trunk is still spacious enough
for two golf bags.
The stance is wide. Low. Ground hugging. The lines flow smoothly
from start to finish unbroken in the signature FISKER style. The
overall look conveys movement, speed and power, whether the
power-retractable hardtop is secured for foul-weather driving or
stowed for open-air motoring. Compared to its original platform,
the TRAMONTO is reproportioned with a slimmer, ultra-modern back
end, a longer looking hood line with a pronounced power dome, and
no visual bumpers. It is poised, balanced, sculptured
and exotic.
From any angle, the message is uncompromisingly beautiful.
Unmistakably FISKER.
