It seems so, at least from the uncamouflaged photos spied by a Japanese car magazine. Nothing is firm although the magazine claim the super-sedan will be powered 5.0L V8 mill punching 456PS. More obvious than the hidden engine is the more aggressive outtake of GS F-Sport version bodykit, with more pronounced front bumper opening, flared front airdam with blistered front wheelarch, more aggressive side skirting and rear lower valence accompanied by quad exhaust setup arranged in similar manner to the older IS-F. The skirtings are all carbon fibre finished. Similar finishing is spotted on the side mirror rear duck-tail spoiler. The larger alloy wheel is finish in dark tone as well. Two more photos after the jump.
