What started as an IS 350 F SPORT has evolved into the most aggressive performance-focused project car Lexus has displayed at SEMA.
Testing at more than 600 horsepower (hence the name), this new flagship turbocharged engine derived from the parent brand’s Dynamic Force engine lineup allows this Lexus take F SPORT to a new level.
The sports sedan is powered by the thoroughly modern, all-aluminum V35A V6 engine featuring 3.5-liters of displacement fed by a pair of billet compressor wheel turbochargers.
The engine combines both port and direct fuel injection as well as efficient breathing to help deliver superior response and consistent performance.
Liquid-to-air intercoolers are integrated into the compact package to help lower intake charge temperature and improve power.
Sourced from the LS 500, this ultra-efficient engine with massaged CT28 turbos has been leveled up with increased boost levels and recalibrated fuel and ignition curves to allow this IS to see over 600 horsepower on E85 fuel in a motorsports trim.
To increase driver engagement, a Samsonas full-sequential 6-speed transmission is paddle shifted thanks to engine and transmission communication through the Emtron engine management system.
As this is a track-focused project, the chassis has been stiffened with the help of a custom 4-point roll cage and allows for the KW Double Adjustable coil overs to function optimally in keeping the massive Michelins in contact with the pavement.
The RC F Carbon Ceramic brake package helps this IS shed speed as dramatically as it accumulates it.
To achieve desired weight reduction, the rear seats were removed, and the hood and truck were replaced by Seibon carbon fiber units for the sole mission of speed.
The driver can monitor engine functions from a MoTeC Motorsports color dash display while seated and strapped into the Sparco seats and harnesses.
The sedan’s dramatic stance comes courtesy of the Artisan Spirits wide body kit and 19” VOLK racing wheels.
The body is sprayed with Axalta multi-stage custom paint in Lexus OEM hues.
