It has finally been confirmed, folks.

The flagship F-Sport sedan will arrive in 2015, as a 2016 model.

Rumors have been circulating for years that Lexus would bring a V8-powered GS sedan to the table, but now Motor Trend has finally confirmed our suspicions:

At last, Lexus will have a fighter to compete with the BMW M5 and Mercedes E63 AMG. However if the rumors are true, even a 500 HP might not be enough gun for the battle. We were hoping for atleast 550HP, although the base 2014 Lexus GS350 does weigh in at an astonishing light 3,750 lbs – which is pretty lean for a full size luxury sedan. We would expect a high performance variant to shed even more weight, possibly closer to 3,700 lbs – so 500 HP might be the magic number. The lighter weight may be an approach Lexus will take with this new high performance sedan, instead of just throwing up big HP numbers or going forced induction.

Regardless, we are happy to see Lexus slip on their running shoes, finally. The V8 powered RC-F coupe should be hitting dealerships soon, and Motor Trend has also mentioned that a new V8-powered IS-F is on the way, which presumably will be powered by the same 5.0 V8.

Further details show a new 8-speed transmission, along with a Torsen limited-slip diff. We hope to see an official debut from Lexus in a few weeks at the Detroit Auto Show.
