The Impreza WRX STI is a high performance family car from the Subaru compact line-up; it is a performance based flagship model of Subaru that comes in saloon and hatchback patterns. This is a power machine with rally-bred attributes and is an enthusiastic-focused that features a bulk of power with 305 horsepower on a 4-cylinder turbocharged boxer engine. The WRX was introduced in 2008 in modern form and the new models are have received a facelift. The Impreza has been equipped with systematically revised suspension system with the stiffer springs, tweaked front control-arm bushings and a 0.2-inches lower ride height to handle the mountain of 305 horsepower in a family car.
The change has been made to improve the balance of vehicle and to make the ride smooth and better than ever before, along with a lighter steering for a feel of a performance car. The boxer family’s flat-four Subaru Impreza WRX engine of 2.5-litre with the four cylinder pattern has been used to empower the car. It is a 2457cc engine that can generate 305bhp with the torque of 300 lb-ft at 4000rpm to move the whole package. It works on multipoint fuel injection system on petrol that enables the WRX STI to achieve the hallmark of 155miles per hour and the acceleration of 0-62 miles just in five seconds. The fuel economy is17mpg in city, 28mpg on motorways and the 22mpg combined with the CO2 emissions of not less than 243gm/km.
The Impreza WRX STI is blisteringly furious but costs some fortune to run it. A six speed manual gearbox system is the only advantage over the competitors like the EVO that offers a paddle shifted manumitted transmission. Brembo supplied brakes allow the carEUR(TM)s De-accelerative expertise to equal its acceleration abilities, it consists of four piston calipers with 13 inches rotors up front and 12.6 inches calipers and two piston calipers at the rear. This Subaru Impreza provides the power to all of its four wheels through the symmetrical all wheel system. A mechanical limited slip type centre differential enhances an electronically controlled centre differential to improve the torque transfer performance.
The default torque split is 41:59 front/rear although the centre differential can be set to an even 50:50 tears. Drivers can tune the throttle response through SI-DRIVE system by just switching between the three different modes. This system is a standard entry in the Impreza cars.

The limited trim adds full leather upholstery, a sunroof, fog lights and a 18 inches BBS aluminum-alloy wheel set.
The drivers can add a navigation system as an option in the Impreza WRX STI cars although different dealers are installing the system as accessories of the car. If we consider the safety factor, then STI is a reliable car anyways, all models of come with standard airbag system, with the dual front, front-side and full-length side curtain air bags, in addition to traction and stability control system and the remarkable electronic brake force distribution. However the Subaru models are regularly scoring the high points on the annual drive power satisfaction surveys so the ownership should be a hassle free practice.
