The 2003 mid engine NSX offers two
distinct powerplants. The first is an all-aluminum 3.2-liter V-6 that
produces 290 horsepower and 224 lb-ft of torque mated to a 6-speed
manual transmission. The second is an all-aluminum, 3.0-liter V-6 that
produces 252 horsepower and 210 lb-ft of torque mated to an
electronically controlled 4-speed automatic transmission with Formula
One-inspired Sequential SportShift.
Both engines are normally aspirated and
are equipped with dual overhead cams, 4 valves-per-cylinder, a Variable
Valve Timing and Lift Electronic Control (VTECTM) system, and
a Variable Volume Induction system. They also feature Programmed Fuel
Injection (PGM-FI) and a direct-ignition system that uses six individual
coils, one mounted atop each spark plug, instead of a single coil for
all six cylinders.
The chassis features all-aluminum
construction for light weight. The 4-wheel, independent double-wishbone
suspension features aluminum-alloy control arms and hub carriers front
and rear to minimize unsprung weight for optimum handling.
Aluminum subframes for the suspension
further reduce suspension mass. The braking system features
large-diameter, ventilated 4-wheel discs and an advanced 4-channel
Anti-Lock Braking System (ABS). The sophisticated Traction Control
System (TCS) has been designed to help limit wheel-spin and enhance
