Acura NSX 1991 Sports Car Specification

The 1991 Acura NSX is a landmark sports car that combines advanced engineering with a sleek, aerodynamic design. At its heart is a mid-mounted 3.0-liter V6 engine, delivering 270 horsepower and 210 lb-ft of torque. This powerplant features Honda's VTEC (Variable Valve Timing and Lift Electronic Control) technology, which optimizes performance across different engine speeds. The engine is paired with a 5-speed manual transmission, offering precise and responsive gear shifts, while an optional 4-speed automatic transmission is also available.

The NSX's chassis is constructed from aluminum, making it the first production car to utilize this lightweight material extensively, resulting in a curb weight of approximately 3,000 pounds. The suspension system employs a double-wishbone setup both at the front and rear, contributing to exceptional handling and ride quality. The braking system is equally advanced, featuring ventilated disc brakes with ABS (Anti-lock Braking System) for reliable stopping power.

Inside, the NSX offers a driver-focused cockpit with leather-trimmed seats and a range of amenities, including automatic climate control, a premium audio system, and power windows and locks. The dashboard is designed for minimal distraction, with clear analog gauges and well-placed controls. Safety features include a robust aluminum frame and dual airbags.

Aerodynamics play a crucial role in the NSX's performance. The car's low stance, pop-up headlights, and integrated rear spoiler reduce drag and enhance stability at high speeds. The NSX rides on 15-inch front and 16-inch rear alloy wheels, wrapped in high-performance tires for excellent grip.

Overall, the 1991 Acura NSX is a pioneering sports car that blends cutting-edge technology with timeless design, offering an exhilarating driving experience and setting new standards in the automotive industry.
