Subaru has unveiled its own version of Toyota’s FT-86 at the Frankfurt Motor Show. Called the BRZ Prologue, it was unveiled in a somewhat unfinished guise with a see-through body showing off the coupe’s internals. The company calls it the “SUBARU BRZ PROLOGUE – BOXER Sports Car Architecture II”

The BRZ features a rear-wheel-drive layout and is fitted with a normally-aspirated 2.0 litre Boxer engine which is exclusively developed for the coupe. The engine features a revised bore and stroke setting and also features Toyota’s direct injection and port injection technology which is commonly known as D-4S.

Subaru promises that the BRZ will offer “Pure Handling Delight” and confirmed that production is expected to start in spring 2012. Subaru also revealed the dimensions of the vehicle which includes a 2,570mm wheelbase. The vehicle is 4,200mm long, 1,770mm wide and 1,270mm high.
