The 2003 Porsche 911 Turbo continues a
performance legend begun when the first 911 Turbo was introduced to
North America in 1976. With a 415-horsepower (SAE) twin-turbo engine and
advanced all-wheel drive, the latest 911 Turbo takes its place in the
top echelon of the supercar category.
Derived from the Porsche GT1 racecar, the
3.6-liter, horizontally opposed six-cylinder engine sustains 415 lb.-ft.
of peak torque from 2,700-4,600 rpm. In place of a conventional throttle
cable setup, the E-Gas electronic throttle transmits pedal position to
the engine control unit.
Power drives through a standard six-speed
manual transmission. The advanced Tiptronic® S five-speed automatic
transmission is available as an option.
The 911 Turbo can accelerate from 0-62
mph (0-100 kph) in just 4.2 seconds. On the test track, the 911 Turbo
can sprint from a standstill to 100 mph (160 kph) in only 9.2 seconds
and achieve a top speed of 189 mph (305 km/h).
An optional engine enhancement
performance package increases the twin-turbo engine’s output to 444
horsepower (SAE) and 457 lb.-ft of torque.
The standard Porsche Stability Management
system (PSM) can detect a loss of grip at the front or rear and reduce
instability by applying braking to individual wheels and, if necessary,
altering engine power.
The upper part of the two-piece rear
stabilizer wing automatically rises at speeds above 75 mph (120 kph) and
lowers at speeds below 50 mph (80 km/h).
The standard aluminum hollow-spoke alloy
wheels measure 18 x 8 inches in front and mount 225/40 ZR18 tires; the
18 x 11-inch rear wheels mount 295/30 ZR18 tires. Also derived from the
GT1 racecar, one-piece, four-piston monobloc brake calipers reduce
unsprung weight and heat and feature 13-inch (330-mm) vented,
cross-drilled discs front and rear.
Standard Bi-Xenon headlight clusters
feature xenon high-intensity discharge headlights for both the low and
high beams. |
