2007 Subaru Legacy 2.5 GT Spec.B



SI-DRIVE The SI-DRIVE (Subaru Intelligent Drive) system allows the driver to choose from three electronic engine controls or maps. These are chosen by a rotary switch on the center console. Changes to engine mapping modify the operation of the electronic throttle system, turbo wastegate and variable valve timing. These affect engine torque, maximum power and even the throttle response curve. The three SI-DRIVE settings are Intelligent, Sport and Sport Sharp. Mode selection can be made “on the fly,” and the current SI-DRIVE mode is indicated on a display within the tachometer. Characteristics of the three modes:
  • INTELLIGENT improves drivability in low-traction driving conditions and fuel economy by as much as 10 percent 
  • SPORT – provides a more linear feeling with quicker throttle response; it feels like the 2006 Legacy 2.5 GT, only smoother
  • SPORT SHARP – performance improved over the 2006 Legacy 2.5 GT, with quicker throttle response and delivery of engine power, narrowing the gap between it and the Impreza WRX STI
The differences between the three modes are pronounced. SI-DRIVE gives the driver three different vehicles in one.

Added to the Legacy 2.5 GT spec.B’s drivetrain for 2007 is a Torsen® limited-slip rear differential, enhancing the traction provided by the car’s Symmetrical AWD. Subaru Vehicle Dynamics Control (VDC) is another new chassis feature. This system applies braking power and/or reduced engine torque to help correct the car’s direction in situations where it starts to understeer or oversteer. Spec.B features also include the Tire Pressure Monitoring System for 2007.


Another performance-enhancing feature standard in the spec.B is the SI-DRIVE system – Subaru Intelligent Drive, which will be standard in all 2007 turbo-powered Legacy and Outback vehicles. This driver-controllable engine-management system allows the driver to choose from three settings to match driving conditions and style.


Inside, the 2007 spec.B adds an eight-way power driver’s seat with two-position memory and a split fold-down rear seat with trunk pass-through.


The audio system benefits from added features, including an auxiliary input jack in the center console, MP3/WMA playback capability, SRS WOW sound enhancement and XM® Satellite Radio capability.




Recognized by enthusiasts and the automotive press since its introduction, the spec.B’s capabilities improve significantly for 2007. Put the Legacy 2.5 GT spec.B on your list for a test-drive!
