The automotivenews.com website says it has been told that a blown 2.0-litre engine is being developed using a single twin-scroll turbocharger and direct injection.
It speculates that such an engine could generate up to 209kW of power and 340Nm of torque – almost identical in output to a six-cylinder Holden Commodore SV6 (210kW/350Nm). The current BRZ is a massive 445kg lighter than the Commodore.
Put another way, the BRZ turbo would produce around 169kW per tonne – only slightly less than a Porsche 911 Carrera coupe (174kW/tonne). The 911 Carrera sprints to 100km/h in 4.8 seconds.
