It's been a while since we've heard rumors of the fabled high-performance Lexus GS F, but thanks to our eager spy photographers, this looks to be our first real proof of the machine's existence. We don't have the usual brace of photos from all angles to work with this time around, our spies saying that every time Lexus' garage door opened, engineers jumped in front of the cameras to prevent the car from being photographed.
Even so, we have a pretty clear glimpse at some significant changes to this GS sedan, including the same staggered, quad-pipe exhaust found on the Lexus IS F. There's also an air diffuser panel nestled between the exhaust outlets, as well as a larger lip spoiler and unique wheels (matching those of the RC coupe) wrapped in high-performance tires.
Last time we heard rumors of the GS F's existence, sources predicted that the M5-fighting sedan would use a tuned version of Lexus' 5.0-liter V8, producing something like 465 horsepower. We have also heard that the automaker plans to reduce weight wherever possible, and that the final curb weight will be something like 3,700 pounds.
Of course, those earlier reports said we'd see the car as early as 2012, and that obviously didn't happen. These days, our spies' best guess is that the GS F will arrive in time for the 2015 model year.
