Unlike our previous spy shots, though, this time around, the sporty Lexus has been caught testing on the Nürburgring, so our spy shooters have managed to get a look at the car from all angles. Building on the aggressive styling of the GS F-Sport, the GS F gets bigger air intakes and a lower chin spoiler up front. Like before, we see the signature stacked exhaust outlets, but they still seemed roughed into rear fascia, which gets an aero-aiding diffuser.
We still only have guesses as to what will be under the hood, but a 465-horsepower, 5.0-liter V8 sounds good to us. Expect to see the production GS F on the road by 2015.
