Power comes from the automaker's 5.0-liter naturally aspirated V8 – the same eight-pot that powers the RC F – good for 467 horsepower at 7,100 rpm and 389 pound-feet of torque that comes on strong between 4,800 and 5,600 rpm. That force is sent to the rear wheels via Lexus' eight-speed automatic transmission.
In order to make this F a significantly better-handling vehicle than the standard GS, Lexus is fitting its Torque Vectoring Differential from the RC F, which uses three modes – Standard, Slalom, and Track – to alter torque delivery to better suit different driving dynamics. Lexus has released a few preliminary specifications about the GS F, so we know the sedan tips the scales at 4,034 pounds and will ride on 19-inch wheels with 255/35-series tires up front, and 275/35 rubber out back.
This all sounds pretty good, but we can't help feel a wee bit disappointed, especially considering the numbers being thrown down by competitors like the BMW M5 and Mercedes-Benz E63 AMG, not to mention the new 640-hp, 200-mph Cadillac CTS-V that'll also debut at next week's Detroit show. Still, if the Lexus RC F is any indication of the brand's future performance offerings, we don't doubt the GS F will, at the very least, be a super fun car to toss around.
Stay tuned for the GS F's official unveiling, next week.
