In "Sport Sharp" mode, SI-Drive modifies the engine's electronic throttle mapping to deliver lightning quick throttle response and more power sooner. Delivering maximum driving enjoyment, this mode is ideal for tackling twisty roads and for merging or overtaking other vehicles on the highway with confidence.

On 2007 Legacy and Outback models equipped with the 5-speed automatic transmission (not available on Legacy 2.5 GT spec.B), SI-Drive also changes the transmission's shift patterns. It will hold each gear longer through the rpm range and downshift more quickly under hard acceleration, depending on the mode selected.

The SI-Drive system includes instrument panel displays that allow the driver to monitor performance. The multi-information display located in the tachometer face - in addition to providing trip computer functions - denotes the selected SI-Drive mode and provides an active torque curve display. 

When "Intelligent" mode is selected in vehicles with a manual transmission, a shift-up indicator blinks to signal the optimal shift point for maximum fuel efficiency.



Symmetrical All-Wheel Drive + Vehicle Dynamics Control

2007 Subaru Legacy 2.5 GT spec.B is equipped with one of the industry's most effective combinations of all-weather handling technologies: Subaru Symmetrical All-Wheel Drive plus Vehicle Dynamics Control (VDC), a stability system that was previously available only on the B9 Tribeca SUV model and the top-line Outback.

Teamed with a manual transmission as in the Legacy 2.5 GT spec.B, Subaru Symmetrical All-Wheel Drive employs a viscous-coupling locking center differential with a normal 50:50 torque split. Slippage at the front or rear wheels will transfer more power to the opposite set. Vehicle Dynamics Control (VDC) is an advanced stability system that can help keep the vehicle going in the direction the driver is steering, especially in slippery road conditions. The system can be deactivated for conditions that require some wheel slippage, such as extricating the car from deep snow. New for 2007, a Torsen limited-slip rear differential helps to optimize traction at the rear wheels.


Exclusive Bilstein Sport Suspension

The exclusive Bilstein Sport Suspension equips the Legacy 2.5 GT spec.B model with performance-tuned shock absorbers for improved cornering response. Subaru replaced the MacPherson strut front suspension of other Legacy models with an inverted strut configuration similar to that in the rally-bred Impreza WRX STI, including aluminum-alloy lower control arms. 

The multi-link rear suspension features aluminum-alloy rear arms and upper links in place of cast-iron pieces to reduce unsprung weight (and thereby enhance handling response). Finally, the 18-inch alloy wheels are fitted with 215/45 R18 Bridgestone Potenza RE050A summer performance tires. (The standard Legacy 2.5 GT Limited models feature 17-inch alloy wheels and all-season tires.)

A 4-wheel disc Anti-lock Brake System (ABS) with Electronic Brake-force Distribution (EBD) is standard on all Legacy models. The 2.5 GT Limited and 2.5 GT spec.B models employ larger brake rotors than other Legacy models, with ventilated rear discs in place of solid discs.


Distinct, Sophisticated Design - Outside and In

Subaru Legacy 2.5 GT spec.B not only appeals to driving enthusiasts for its performance, but for its appearance that is both distinctive and "stealthy." The Legacy 2.5 GT spec.B is quickly identified by its aerodynamic side ground-effects moldings with chrome trim. The road-hugging stance of the spec.B is further accentuated by the exclusive 18-inch wheels.
