The Acura Division of American Honda introduced earlier this year the 1990 second-generation Integra sports sedans. The Integra line includes 3-door hatchback and all-new 4-door sedan body styles, as well as a new GS trim level for each.
The 1990 Integra has a new 1.8-liter DOHC fuel-injected engine, which produces 130 horsepower, 4-wheel double-wishbone suspension, a new, speed-sensitive variable-assist power steering system, and ergonomically designed interiors and controls. The new GS model features an Anti-Lock Braking (ALB) system -- a feature rarely found on automobiles in this price class.
The distinctive, wedge-shaped Integras were designed using the latest Computer-Aided Design (CAD) techniques and extensive wind tunnel testing to achieve rigid body structures and excellent aerodynamics. The 3-door achieves a coefficient of drag rating of 0.32, while the 4-door sedan is rated at 0.34.
Design features include slim roof pillars and sashless doors, for a contemporary "hardtop" look. The extensive use of glass results in over 320 degrees of outward visibility for the driver.
Powering the 1990 Integra is a new, 4-cylinder engine that benefits from technology developed through Honda Research and Development's championship-winning Formula 1 racing program. The all-aluminum engine displaces 1834 cc's (1.8 liters) and has dual overhead camshafts, 4-valves-per-cylinder and Programmed Fuel Injection. It develops 130 horsepower at 6000 rpm and 121 lbs.-ft. of torque at 5000 rpm.
The combustion chambers are a pent roof design and have centrally-located spark plugs for optimum flame propagation and thorough combustion. The 4-valve-per-cylinder configuration, combined with careful tuning of the intake and exhaust systems increases torque, especially in low and mid-range rpm. A 5-speed manual is standard equipment and features larger synchromesh gears for first and second gears, to better handle the engine's increased torque. A short throw shift lever provides crisp, precise feel.
An electronically-controlled 4-speed automatic transmission with driver-selectable sport mode is also available. Borrowing technology from the Acura Legend, this sport mode allows the transmission to shift at higher rpm points for more spirited driving.
The second-generation Integra utilizes a 4-wheel fully independent double-wishbone suspension. Handling and comfort are enhanced by front and rear stabilizer bars, new front nitrogen gas-pressurized shock absorbers and progressive-rate rear springs.
The rack-and-pinion steering employs a new, electronic, speed-sensitive variable power-assist system that provides a more linear transition between assist levels for more precise and responsive steering feel.
Braking is accomplished with standard 4-wheel disc brakes. Integra GS models include a new Anti-Lock Braking (ALB) system which uses sensors at each wheel to detect impending lockup. Once detected, the ALB system modulates hydraulic pressure to allow the wheels to continue rotating *ith no loss of braking power, while maintaining steering control.
