Track testing of the first GT race car to be developed by McLaren Automotive's new customer racing division is well underway and will see the McLaren 720S GT3 test extensively across Europe, the U.S.A and Middle East. The new GT3 challenger, which is based on the acclaimed 720S supercar, is being readied for its competition debut in 2019 when it will be eligible for all GT3 grids globally.
The tail of the 720S GT3 gets an aerodynamically-optimised GT3-specification rear wing
As with the road car, at the heart of the 720S GT3 is the light but immensely stiff carbon fibre MonoCage II chassis structure. A race-prepared version of the M840T 4.0-litre twin-turbo V8 engine provides the power.
The focus on pure engineering, innovative aerodynamics and efficient design that makes the 720S road car so incredibly impressive provides the ideal starting point for the journey from multi-talented supercar to be the strongest contender yet from McLaren for GT3 racing honours.
Although intrinsically the same mid-engined coupe as the McLaren 720S road car, more than 90% of components have been changed or optimised in some way for the GT3 version. The combination of changes to bodywork, aerodynamics and suspension; revised transmission and a new braking system and the performance of the Pirelli racing tyres will deliver a significantly enhanced car born to race on the most demanding circuits.
The innovative aerodynamics of the 720S road car have been further developed to deliver even greater race track stability and aerodynamic efficiency. The lightweight, carbon fibre and composite body panels are all unique to the 720S GT3, while a bespoke splitter, floor assembly and dive-planes distinguish the front and the tail gets an aerodynamically-optimised GT3-specification rear wing.
A new braking system comprises an optimised brake caliper design and enhanced brake cooling for maximum performance and longevity. New rear suspension geometry is matched with four-way adjustable dampers and coilover springs to provide the aerodynamic optimisation needed to ensure balanced handling and improved corner entry stability. Driveshafts and wheel hubs are race-oriented and a fast-change, centre-lock wheel design minimises the time required for wheel changes during pitstops. An air-jacking system is also in-built.
FIA-approved GT3 race equipment fitted as standard includes an all new roll cage, winged-headrest seat and six-point harness, roof-hatch extraction system and side-impact foam.
