Article Summary
April 14, 2006 Japanese industrial heavyweight Fuji Heavy Industries (FHI), the maker of Subaru automobiles, today announced the development of its SI-DRIVE (Subaru Intelligent Drive), an innovative driving enhancement system that provides optimal control of the powertrain unit and delivers driving pleasure under various traffic and road conditions. The company displayed a Legacy sedan 2.5GT equipped with the new system, at the New York International Automobile Show. The SI-DRIVE enables three distinctively different modes of engine power characteristics by regulating the engine control unit (ECU) as well as the transmission control unit (TCU) in the automatic transmission, and by fine-tuning the electronically controlled throttle. Intelligent mode ensures smooth, strong power output, yet facilitates city driving at low- to mid-speed range and contributes to greater fuel economy. The Sport mode is designed to deliver ideal power, faithful to the driver’s acceleration, and heightens enjoyable, sporty driving under a wide range of road conditions. The Sport Sharp mode further elevates sporty driving by accurately responding to the driver’s acceleration and boosting engine revolutions earlier than the Sport mode for a more powerful driving experience. The SI-DRIVE selector will be installed on the center console for the driver to choose from these three modes, which bring out very different driving experiences while driving the same car.
