Innovative Technology Highlights Acura Automobiles
Acura automobiles in 1987 will continue to be among the leaders in automotive technology, using the latest in proven engineering and design to make driving a pleasurable and satisfying experience
Both the Acura Legend, a 4-door luxury touring sedan, and the 3- or 5-door Integra sports sedans feature an aluminum alloy engine block and head with a four valve per cylinder configuration, which improves the breathing of the engines and enhances both performance and efficiency. The Integra engine also incorporates dual overhead cams, enabling its 1.6 liter displacement to generate 113 bhp while weighing only 207 lbs. The Legend engine features a single overhead cam and a 90 degree V-6 design to facilitate its, low, sloping hood; the crank pins are offset by 30 degrees to eliminate vibration caused by the uneven firing intervals associated with 90 degree V-6 engines.
Programmed fuel injection, derived from Honda's highly successful Formula 1 racing involvement, delivers the precise amount of fuel for optimum power and combustion efficiency. Featured in both the Integra's four cylinder dual overhead cam engine and the Legend's 24-valve, 151 bhp V-6 power plant, the fuel injection system is controlled by a microcomputer. Constantly monitoring information from seven sensors, the fuel injection system delivers the precise air/fuel mixture to each cylinder.
Suspension systems for the Legend and Integra are designed to provide excellent handling and good road feel. Disc brakes on all four wheels are standard on all Acura models; the front discs are ventilated for better cooling.
Front wheel drive with a transversely mounted engine is a basic design feature of both Acura models. By using equal length halfshafts to deliver power to the front wheels, the torque steer found in some front wheel drive models is virtually eliminated.
All Acura models have exterior styling that reflects extensive wind tunnel testing. The wedge-shaped design of both the Legend and Integra, along with such features as faired side mirrors and bumpers flush glass surfaces, flush door handles and smooth underbody contribute to outstanding aerodynamics for both models. The Integra has a coefficient of drag (Cd) of just 0.34, while the Legend is even lower at 0.32
Excellent aerodynamics are more than a styling exercise. By minimizing the amount of disturbance as they move through the air, both the Legend and Integra enjoy reduced wind noise, while efficiency and performance are enhanced.
The interior design of the Legend and Integra reflects the design science of ergonomics. All switches and controls are located within easy reach of the driver. Analog instruments are large, easy to read and clearly illuminated. Seats are comfortable, offering both adequate support and adjustability for driver and passenger.
Ergonomic design is also evident in the small, seemingly less important aspects of Acura automobiles. Switches are not only large and easy to reach, but provide the driver with positive tactile feedback so that he knows, without having to look away from the road, that the desired function has been activated. Coin boxes are ribbed, so that change can easily be picked up. Cruise control switches are easily reached on the steering wheel itself. And on the Legend, a small pod on the dashboard allows the driver to adjust radio volume and select stations without the hand leaving the steering wheel.
This close attention to ergonomics goes beyond providing comfort for the driver and passenger. By minimizing distractions and driver stress, Acura Legend and Integra automobile increase both the enjoyment and safety of driving.
