More Photos of the Lexus GS F Test Mule

Posted by Kevin on July 29th, 2013

A couple weeks back, a modified Lexus GS test mule was spotted alongside the camouflaged RC F coupe — today, Auto Evolution has new photos of what could be the GS F high performance sedan:

Lexus GS F Test Mule

Despite the standard body shell, the quad-exhausts and exaggerated rear air diffuser are clear signs that this is no ordinary GS — the GS is also wearing the same LFA Nürburgring wheels seen on the RC F prototype, though they do look deceptively small.

There is one curious detail: the GS lacks the hood vents and fender vents seen on the RC F prototype — by omitting this type of performance boosts, just what are these engineers testing?

(Big request to all the spy photographers out there — get some photos of the front end!)

People please the GS F is going take the BMW M5 and Merc E63 AMG head on. It's not a competing in the 3 serious segment.

Most of the vents are just for looks. You can test the whole car without those. That doesn't mean a thing.

it looks like the front seats have different style than those in the normal GS and the GS-F sport, so it could be GS-F or....i dont know...

I wish the GS F could just dethrone the current M5 in its first generation.

There are 3 RC-F prototypes, and one GS-F type thingy (above). They could just be testing out a series of different set ups, perhaps even engines, as I've only seen 1 out of the 3 RC-F's in the videos where we hear the V8.

    A GS body wouldn't fit this perfectly over an IS/RC platform. This GS-something looks production ready.

    I know, but they've been seen driving at least 2 of the RC-F prototypes with a trailing GS-F. Logic would assume they are comparing something between the RC-Fs or against a GS-F.

    A GS body wouldn't fit on IS/RX platform , but the engine , transmission & differential can fit onto GS body nicely ... what I meant is , the GS is a test mule that carry IS-F or RC-F's stuff for regular road test without being spotted . Who knows ? Maybe that GS already on the road for a while ?

We can't see the front quarter panel so we don't know if it has side vents or not. As for the hood being the same, the GS F's engine bay may be large enough that it doesn't require the bulge seen in the IS F. Hood vents might not be needed either since we don't know what kind of set up is being used.

The exhaust tips dont fit the rear bumper. It's just a mule.
