Subaru customers can have their standard 4-door or 5-door STI with upgraded engine power and a satellite navigation system at the same OTR price of £32,995 from April 1 until June 31, 2011. In its standard trim, the 2.5 litre Subaru Boxer 16-valve turbo engine already produces a power of 300 PS at 6000 rpm and 407 Nm at 4000 rpm.
Customers purchasing an STI within the qualifying period will get the engine upgrade, which has been developed at Subaru UK in-house, resulting to an extra 20 PS and enhanced mid-range torque.
The upgrade will bring the engine to produce even more impressive final figures of 450 Nm at 3400 rpm. A Subaru UK warranty is also included. With a sub five second sprint to 62 mph, STI can be categorized as a supercar, dispatched in just 4.9 seconds.
The STI of qualified customers are also fitted with a Pioneer sat nav, which has iPod and Bluetooth connectivity as well as touch-screen capability.
The screen can also be detached to connect to a laptop through a USB port for convenient data transfers. Other standard features of the STI include leather Recaro seats, climate control, SI-Drive, hill start assist, keyless entry and push button start, satellite tracker, cruise control, symmetrical AWD, 18 inch alloy wheels, and remote locking.
