Right now you can go and buy the latest Subaru Impreza, which rides on an all-new platform. However, the current WRX and WRX STI are still based on the previous Impreza, leaving many to wonder when their respective replacements will arrive. Despite the duo receiving a refresh for 2018, Motoring confirmed with Subaru Australia Managing Director Colin Christie when those successors are expected. The answer: two-and-a-half to three years.

Looking back, that's the same time frame between the 2012 Impreza's launch and the 2015 WRX and WRX STI. The current gen Impreza was launched for 2017. At the moment, details about the duo's powertrain are non-existent, but we suspect a turbocharged version of the Impreza's 2.0-liter Boxer four is a viable contender. As is the case with today's STI, its successor will probably have a different engine than the WRX, which has a turbo 2.5-liter Boxer four. Alternatively, both cars could share the same turbo boxer four, with the STI featuring an electric motor for added boost. It's certainly an intriguing idea we'd love to see happen. Until 2020 or so, the 2018 WRX and WRX STI are now on sale.
