It seems Lexus is preparing a new GS F sedan for production in the 2016 model year. Reports confirm the performance sedan->ke142 will be powered by an upgraded, 5.0-liter V-8 that powers the upcoming RC F coupe. The GS F will also get an eight-speed automatic from ZF, along with a Torsen rear differential as standard equipment.

We can expect the GS F’s V-8 to pump out roughly 506 horsepower and just under 400 pound-feet of torque. That should put the four-door sedan in the mid four-second range to 60 mph and at a top speed exceeding 170 mph.

Holding everything together will be a lengthened version of the RC’s->ke4751 chassis. A multi-link, electronic suspension with separate drive modes is also expected. The new GS F will borrow some of the RC F’s styling cues, including that massive Lexus->ke47 Spindle Grille. Expect the GS F to cost around $130,000 when it hits the market.

What’s more, Lexus is apparently working on a four-door version of the RC F. If that’s the case, it will surely ride on the same lengthened platform as the GS F and share much of its underpinnings. It may be a case of slight size and styling differences being the only separators. AutoCar is reporting the four-door RC F is likely to bow "sometime in 2016" as well.

Why it matters

With the addition of two four-door performance sedans, Lexus would push itself into a big fight with its German rivals -- a fight the entire world would love to watch. With V-8 power under the hood and mid four-second times to 60 mph, the GS F would be a strong competitor. It’s interesting to wonder why Lexus would bring out a four-door version of its RC F, especially when it will already be building the GS F. Only time will tell if these reports hold true.

Lexus RC F

The all-new 2015 Lexus RC F is a beast of a car. Powered by a 467-horsepower, 5.0-liter V-8 and backed by an eight-speed automatic transmission from ZF, the RC F is a strong performer. Its unique exterior design separates it from anything else on the road today.

Squarely aimed at the BMW M4->ke4183, the RC F has some big shoes to fill. But with its stout V-8, quick-shifting transmission, and a less-expensive price tag, the BMW M4 has been put on notice.

The RC F will hit showrooms in the fall of 2014 with a sticker price starting at $63,325.
