1998 Acura NSX
Throughout 1998, the Acura NSX continues as Acura’s ultimate exotic sports car by combining world-class performance, styling, and prestige with exceptional refinement, driveability, and reliability.
The mid-engine, 2-seater Acura NSX offers two distinct powerplants. The standard engine is an all-aluminum 3.2-liter V-6 that produces 290 horsepower and 224 lb-ft of torque and features a 6-speed manual transmission. An electronically controlled 4-speed automatic transmission with Formula One-inspired SportShift mode is optional and comes with an all-aluminum, 3.0-liter V-6 which produces 252 hp and 210 lb-ft of torque.
Both engines are normally aspirated and are equipped with dual overhead cams, four valves per cylinder, a Variable Valve Timing and Lift Electronic Control (VTEC) system, and a Variable Volume Induction System intake configuration. They also offer Programmed Fuel Injection (PGM-FI) and a direct ignition system that uses an individual coil mounted atop each spark plug instead of a single coil for the entire system.
The chassis features all-aluminum construction for lightweight. The 4-wheel independent double-wishbone suspension also features aluminum-alloy control arms and hub carriers front and rear, and aluminum subframes for the front and rear suspension. 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 wheelspin and enhance control.
The standard engine on the Acura NSX is an all-aluminum, 90-degree, 3.2-liter (3179 cc), dual-overhead-cam, 4-valve-per-cylinder V-6 which produces 290 horsepower at 7100 rpm and 224 lb-ft of torque at 5500 rpm. It is mated to a 6-speed close-ratio manual transmission. Redline is at 8000 rpm.
The optional electronically controlled 4-speed automatic transmission comes with an all-aluminum, 90-degree, 3.0-liter (2977 cc), dual-overhead-cam, 4-valve-per-cylinder V-6 which 252 horsepower at 6600 rpm and 210 lb-ft of torque at 5300 rpm. Redline is at 7500 rpm.
An exclusive electronically controlled Variable Valve Timing and Lift Electronic Control (VTEC) system optimizes volumetric efficiency at both high and low engine speeds. A unique Variable Volume Induction System changes the configuration of the intake system with varying engine speeds, working with the VTEC system to broaden the torque curve and increase peak power output. The 3.2-liter engine boasts a stainless steel exhaust header system to improve engine breathing.
