The Agera R made its debut at the
March 2011 Geneva Motor Show
-with a Speed Racer livery theme, and special Michelin tyres. It can accelerate
from 0-100 km/h (0-62 mph) in 2.8 seconds and
reach a theoretical top
speed of 439 km/h (273 mph). The
Agera R has a drag coefficient of Cd=0.37,
or Cd=0.33 at high speed due to its adaptive rear wing,
while producing 300 kg
(660 lb) of downforce at 250 km/h (155 mph). This adaptive rear wing system is lig
hter than
conventional hydraulic/electrical adaptive systems, and has the unique
ability to compensate for
head/tailwind due to its spring-loaded design. Furthermore,
the pylons holding the wing play not only a role
in the Agera R's aerodynamic performance,
but also assist in extracting hot air from the engine
bay. On 2 September 2011, during test
sessions in
Ängelholm, the Agera R broke six world land speed records for a production car,
including 0-300 km/h
(0-186 mph) in 14.53 seconds, and 0-300-0 km/h in only 21.19 seconds.
The braking performance required
to maintain this record is enabled in part by the Agera's
stability, demonstrated by Koenigsegg's test driver and
drivetrain technician Robert Serwanski,
who was recorded by passenger
Rob Ferretti (founder of the group "Super Speeders") braking from
300 km/h to 0 without holding the steering wheel. The Agera R can produce lateral cornering forces
of 1.5 G, due to a combination of mechanical balance
and high levels of grip from the specially
developed Michelin Supersport tyres.
