In a strange and unpredictable marketing strategy, Subaru UK has decided to give potential customers the extra oomph they may need to go out and purchase an Impreza->ke1319 WRX STI. Between now and June 31, 2011, Subaru UK will be selling the standard WRX STI models for the typical £32,995 (about $53,500 at the current exchange rates), but add on an upgrade in engine power and satellite navigation system for FREE. Yes, that's F-R-E-E.

The Subaru Impreza WRX STI comes with a 2.5 liter Boxer 16-valve turbo engine that produces 300 HP, but during this promotional period, the engine will be tweaked to deliver 320 HP and 331 lbs-ft of torque. With this extra 20 HP, the improved STI will sprint from 0 to 60 mph in just 4.9 seconds.

Next to the engine upgrade, the STI will also get a Pioneer satellite navigational system fitted as standard. The system features touch-screen capability, Bluetooth, and iPod connection. The screen is also detachable and can be connected to a laptop via a USB port for easy downloading of additional information.

The list of equipment for the Subaru->ke86 will also include symmetrical AWD, keyless entry and push button start, hill start assist, climate control, SI-Drive, leather Recaro seats, 18 inch alloy wheels, remote locking, satellite tracker, and cruise control.

Subaru UK didn't mention the reason behind this added bonus, but we don't think anyone in the UK will mind.
