Subaru WRX STI gets more power for less money (UK)
 

Subaru’s UK division has announced that the updated WRX STI has a starting price of 26,995 pounds and it can be financed for less than 300 pounds a month. Joining the 320R power upgrade that offers 315 hp (235 kW / 320 PS) and 331 lb-ft (450 Nm) is the new 340R that costs an additional 1,599 pounds. These two power boost kits can be installed retroactively without affecting the warranty of the vehicle.
The Subaru WRX STI 340R produces 335 hp (250 kW / 340 PS) and 361 lb-ft (490 Nm) of torque, which represents an increase of 39 hp (29 kW / 40 PS) and 61 lb-ft (83 Nm) compared to the regular WRX STI. The model is powered by the same horizontally-opposed, 4-cylinder 2.5-liter Boxer engine that has received an ECU remapping, while the new exhaust system has improved the airflow.
Thanks to the power boost, the WRX STI needs only 4.7 seconds to perform the 0-62 mph, making it 0.5 quicker than the standard model. It is fitted with the traditional AWD technology developed by Subaru, a fully-independent front & rear suspension and a Torsen rear differential.
