Acura Integra Coupe

From Acura press: The third-generation Acura Integra (introduced in 1994) features a number of technological innovations that enhance performance and handling, and provide high levels of safety, durability, efficiency, comfort and ride quality. The Integra is available as a Sports Coupe or Sports Sedan, and each body style comes in four trim levels- RS, LS, GS-R, and the Special Edition.

The Integra has evolved and matured in its three generations. The latest edition is the most highly refined, and offers a comprehensive list of standard luxury, comfort and safety features. It features a standard driver's and front passenger's air bag Supplemental Restraint System (SRS) in all models. Additionally, features such as a power antenna, lumbar adjustment for the driver's seat, power windows and door mirrors and an AM/FM stereo/cassette music system are standard in all models.

The Integra features two distinct engines. The RS, LS and Special Edition models offer an all-aluminum, 1.8-liter, DOHC, 16-valve, 4-cylinder engine. This powerplant produces 14- horsepower at 6300 rpm, and 127 lbs-ft of torque at 5200 rpm.

The GS-R model features a 1.8-liter engine equipped with the Variable Valve Timing and Lift Electronic Control (VTEC) system pioneered in the Acura NSX. It also features PRogrammed Fuel Injection (PGM-FI), a dual-stage intake system, a knock sensor, a crankshaft reinforcing bridge, oil jet piston cooling and a number of other innovations to improve reliability and durability, and to provdie smoother operation. All this adds up to 170 horsepower at 7600 rpm and 128 lbs-ft of torque at 6200 rpm.

These impressive figures give it one of the highest specific outputs of any normally aspirated engine sold in the U.S., and its relatively long stroke and high redline give it the highest piston speed of any automobile engine in the world, even faster than the latest Formula One engines.

The GS-R engine utilizes the latest combustion technology to provide a combination of fuel efficiency and power. Because of the low surface-to-volume area of the chamber, minimal surface area is exposed to the heat of combustion and more heat is retained in the expanding gases, resulting in increased thermal efficiency. And the "squish" area around the combustion chamber is also increased, yielding increased gas turbulence, faster flame propagation, and even better efficiency.
