Lexus officially introduced the RC F GT3 Racing Concept at the 2014 Geneva Motor Show. Based on the recently introduced RC F Coupe, the new concept car was developed to meet Group GT3 international racing standards. According to the official press release, Lexus will supply the GT3-compliant vehicles to racing teams starting in 2015, while the testing will begin this year.
Moreover we could see the new RC F GT3 in many races globally, such as the 24 Hours of Nurburgring endurance race in Germany or the Super Taikyu Endurance and Super GT series in Japan.
The standard RC F Coupe is powered by a 5.0-liter V8 engine that generates 450 hp and more than 383 lb-ft of torque. Meanwhile the Lexus RC F GT3 Racing Concept is powered by the same engine, which delivers more than 540 hp. Furthermore, the RC F GT3 Racing Concept has a weight of 2,755.8 lbs.
For a more stable platform for the suspension and for optimized agility, Lexus focused on implementing top-level body rigidity on the new RC F coupe. In fact, it took all of Lexus’ know-how and experience – gained from body design and production – to achieve the desired levels of performance.
The suspension, brakes steering and wheels are all distinct fit-for-purpose for the new Lexus RC, which is also provided with a Torque Vectoring Differential (TVD). This marks the first time that TVD is equipped with a front-engine/rear-drive vehicle.
Meanwhile, the new RC F features massive rocker cross-section, which is nearly double that of the Lexus IS. With the massive rocker panels serving as the main element, the RC F was able to include a rigid front lower brace that connects both sides of the underbody, resulting in greater steering response and roll feel.
Furthermore, more braces are now found on the floor, engine compartment and rear partition, as complemented by more front brace coupling points. In addition, Lexus strengthened the rear suspension member mounts to achieve optimal traction.
Aside from featuring an exclusively developed strong framework, the new Lexus RC F also employed a number of measures to ensure higher degrees of body rigidity. These measures include the use of body adhesives as well as structural adhesive, full-scale adoption of laser screw welding and extra spot welding.
