Subaru has been manufacturing and selling the Impreza WRX, the base vehicle for its WRC (World Rally Championship) entry vehicles, using the Impreza as its base body for many years, and has decided to develop and sell a new exclusive vehicle using the sub-name of the Impreza,"WRX," which has long been an iconic sports model of the company, as the vehicle name. With Subaru's withdrawal from the WRC, development was shifted from a package that had focused primarily on rally victories to a premium sports model that maintained rally field speed while offering a higher level of ride comfort and other qualities. The body was changed from the previous Impreza-based model to one based on the Levorg, the company's wagon model, and was then thoroughly improved in terms of strength and rigidity. On the other hand, the engine and transmission were carried over from the 3rd generation Impreza WRX, but the "EJ20" engine, which was inherited from the Impreza WRX, has won many rally competitions such as the WRC, and it can be said that Subaru's choice was based on practical advantages such as reliability and performance. Since Subaru withdrew from the WRC, the WRX has not competed in the top international rally categories, but it has been entered by private teams in rally competitions around the world and has accumulated numerous victories. Meanwhile, the WRX has also been very successful on-road. The WRX has shown the world its strength and speed on the track as well, winning its class at the 24 Hours of Nürburgring in 2015, 2016, 2018, and 2019.
