Sources close to Subaru have claimed that the next generation of its flagship WRX STI will offer 298kW and 489Nm, as reported by Forbes.
The 2021 WRX STI will reportedly utilise a 2.4-litre flat-four FA24 engine – the newest addition to the FA engine family which was originally co-developed by Subaru and Toyota for use in the Subaru BRZ and Toyota 86.
The claimed figures for the 2021 WRX STI would mark an impressive 54 per cent increase in power from the standard FA24 thanks to reinforced engine internals, optimised timing and improvements to the valves and intake ports.
The reported figures are also a sizeable increase over the current-generation WRX STI’s 2.5-litre flat-four EJ25 engine which produces 221kW and 407Nm.
Assuming the goal posts aren't moved later this year, the 2021 WRX STI could be setting its sights on Mercedes-AMG.
The German performance marque currently holds the record for most powerful production four-cylinder turbocharged engine with its 2.0-litre unit used in the AMG A45 S and CLA45 S outputting 310kW and 500Nm.
Expect the 2021 WRX STI to use a version of Subaru's famous all-wheel drive system that has utilised in the model since its inception.
Although nothing has been confirmed, expect styling to draw heavily from the VIZIV performance STI concept unveiled at the 2018 Tokyo Auto Show.
