Aston
Martin DB9
The Aston Martin DB9 is a grand tourer
launched by Aston Martin in 2004.
DB9 comes in two variants; coupé and "Volante" convertible,
each producing 470 bhp (350 kW/477 PS) coming from
a 6.0L V12 engine, originally taken from its sister
car the V12 Vanquish. The car has an artificial neural
network implemented at the hardware level to detect
engine misfires.
The Aston Martin DB9 Volante is the
convertible version of the DB9 coupe. It is built by
hand in limited numbers and has enhanced styling. It
is powered by the same 5.9 litre, DOHC 48 valve V12
as the DB9 and is completed with 450 bhp (331 kW) and
a top speed of 186 mph (300 km/h). Because it is a
convertible it will do 0-60 mph in 4.9 seconds, two-tenths
of a second slower than the hard top. The Volante is
taller than the hardtop, standing at 51.2 inches (1,300
mm) compared to 50.1 inches (1,270 mm). The transmission
options are either the 6 speed manual or the 6 speed
TipTronic II automatic.
In the beginning of 2008, both the
coupé and Volante were facelifted. The engine
was tweaked to produce 470 hp (350 kW/480 PS) (up from
450), and the centre console was adjusted to match
more closely with the newer DBS model. It also gained
the key and start-up procedure of the DBS, namely,
the Emotional Control Unit.
