Japanese luxury automaker Lexus is planning to launch a competitor for the BMW M5. Built under the GS-F moniker, the high-performance sedan will use a detuned version of the Lexus LF-A model, a 4.6 liter V10 engine with at least 450 horsepower.

Despite the significant power output, the numbers are still pale compared to the new M5 which outputs 550 horsepower and runs to 62 mph in less than 4 seconds with the Launch Control.

Lexus GS-F aims to be a worthy rival for the M5 with both performance and dynamic ability given the driver-focused developments in the all-new GS’s chassis.

The new F10 M5 will launch in the United States next year and it has already received glorious reviews from journalists around the world. The heart of the F10 M5 comes from the engine currently powering the X5M/X6M twins, internally known as the S63. For the first time in an M5, a high-revving 4.4-liter (4395cc) turbocharged V8 finds its way into the engine bay.

The 2012 M5 stands out with its revamped chassis, M-specific suspension (front and rear axle kinematics), M Servotronic steering, Dynamic Damper Control, DSC stability control system including M Dynamic Mode, and of course that wonderful active M rear diff.

The new M5 joins some tough competitors in the super sporty sedan segment. Mercedes-Benz brings to the table the E63 AMG, while Ingolstadt-based Audi throws into the fight the RS6.
