From Acura press: The NSX/NSX-T took a giant step forward in performance with several major enhancements - most notably a larger, more powerful 3.2-liter, 290 hp, V-6 engine with a 6-speed manual transmission. Other significant engineering updates included larger brakes and an improved Anti-Lock Braking System (ABS), refinement to the electric power steering system, application of aluminum alloys for lighter-weight, high-rigidity body panels, adoption of special heat-reflecting window glass and an anti-theft vehicle immobilizer feature.
Today, all NSX's have a removable aluminum roof panel that can be easily stowed under the rear glass hatch. At the same time, the NSX has a variety of styling enhancements to modernize the car's looks and refinements to the chassis ensure its competitiveness as a world-class sports car. The front fascia of the NSX has a high hood, and a redesigned front bumper and spoiler. The front headlights are Xenon High-Intensity Discharge (HID) lamps. Other external styling refinements include mesh side air intakes, a trunk lip spoiler, aggressive exhaust tips and a redesigned taillight configuration. Chassis refinements include a large diameter rear stabilizer bar, firm front springs and big wheels and tires to enhance the car's dynamic handling characteristics.
The enhancements together combine to reduce the car's coefficient of drag from 0.32 to 0.30 and raise the top speed to 175 mph.
The standard engine on the NSX is an all-aluminum, 90-degree, 3.2-liter (3179 cc), dual overhead cam, 4 valve-per-cylinder V-6 that produces 290 hp at 7100 rpm and 224 lb-ft of torque at 5500 rpm. It is mated to a 6-speed close-ratio manual transmission. Redline for this engine is 8000 rpm.
The only factory option for the NSX is an electronically controlled 4-speed automatic transmission that comes with an all-aluminum, 90-degree, 3.0-liter (2977 cc), dual overhead cam, 4 valve-per-cylinder V-6 with a top output of 252 hp at 6600 rpm and 210 lb-ft of torque at 5300 rpm. Redline for this engine is 7500 rpm.
An exclusive, electronically controlled Variable Valve Timing and Lift Electronic Control (VTEC™) system optimizes volumetric efficiency at both low and high engine RPM. A unique Variable Volume Induction System changes the configuration of the intake system in conjunction with varying engine speeds, working with the VTEC system to broaden the torque curve and increase peak power output.
