Subaru has announced a free engine upgrade for the STI, which sees power up to 316bhp

Japanese car maker Subaru now offers its high-performance WRX STI with a free engine upgrade and sat-nav, at no extra cost.

The free power package sees the STI’s 2.5-litre boxer engine pack an extra 20bhp, now up to 316bhp.

There’s also more torque through the mid-range, helping the hardcore STI’s sprint time fall under the five second barrier.

The power upgrade has been developed in-house by Subaru UK, and is therefore backed by the usual three-year warranty.

Also included in the offer is a Pioneer touch-screen Sat-nav, which also features Bluetooth and iPod connectivity.

The STI offer runs until June 31 and applies to both four and five door variants. Prices start from £32,995.
