Chassis, body and suspension
The T.50s Niki Lauda is built around a specially developed, lightweight carbon fibre monocoque. Optimised for weight reduction and structural rigidity, it is constructed using advanced part-binding technology, with carbon fibre wrapped around a honeycomb aluminium core.
This stiffness and strength also contribute to T.50s’s exceptional occupant safety, with precisely engineered deformable areas. Passengers are further protected by an F1-style ‘passenger safety cell’.
Exterior body panels, all unique to the T.50s, are also made from ultra-lightweight carbon fibre. Windows and screens use glazing that has been further reduced in weight from the road car specification.
For exceptional levels of confidence-inspiring on-track dynamics, the T.50s Niki Lauda utilises the same forged aluminium front and rear double wishbone suspension system as the T.50. However, the springs, dampers and anti-roll bar have been respecified to optimise track performance, while the ride height has been lowered to 87mm at the front and 116mm at the rear.
As part of the Trackspeed package, the T.50s Niki Lauda’s chassis can be adjusted to find the ideal setup for its owner. Both the chassis settings and the aerodynamics are fully adjustable.
The T.50s Niki Lauda retains the T.50’s rack and pinion steering, but with a revised steering ratio.
The Brembo carbon-ceramic discs of the T.50 are carried over to the T.50s Niki Lauda (370mm x 34mm front/340mm x 34mm rear), with six-piston front callipers and four-piston rear callipers. The braking system and aerodynamics combine to produce an incredible deceleration of 3.5g. To ensure the brakes maintain their phenomenal performance throughout a track session, new ducting around each wheel is designed to improve brake cooling.
Wheels and tyres
The T.50s sits on unique and exceptionally light magnesium forged 18-inch wheels, weighing less than 6kg each, with Formula One-style lightweight wheel hubs and a centre lock attachment. The wheels are wrapped in Michelin slick tyres, measuring 250mm wide at the front (25/64 18”) and 300mm wide at the rear (30/68 18”). A wet option is also provided.
The T.50s Niki Lauda has a completely new aero, which combines to create 1500kg of downforce. This includes a new 1,758mm-wide, rear-mounted delta wing, the design of which was inspired by the front wing on Murray’s 1983 Brabham BT52 Formula One car and is just as effective today as it was then.
The front of the T.50s features a splitter with a central aerofoil section, which generates huge load figures to balance out those from the rear wing. The splitter’s central channel reduces the car’s sensitivity to pitch while allowing airflow under the car to continue to drive the central diffuser section, keeping the efficiency of the entire aero package high.
Dive planes include horizontal elements paired with a vertical duct to manage wheel arch pressures and tyre wake, reducing drag and improving efficiency. A pair of NACA ducts have been perfectly positioned on the front clamshell in a region of high pressure and where the thin boundary layer is ideal for cooling the large front brakes.
A central fin stretching from the top of the roof to the rear lip of the car has also been added for increased yaw stability. The large vertical face is presented to the airflow during high-speed cornering and helps counteract the momentum of the car towards the outside of the corner.
To further improve airflow and accommodate the central fin, the oil cooling systems for the engine and transmission are now located in side ducts. By placing these systems lower in the car, helps to optimise its centre of gravity.
With the powertrain coolers located directly downstream of the front wheels, barge boards have been added to manage the turbulent wake emanating from the front wheel arches, ensuring a clean flow of air to the side ducts.
The T.50s Niki Lauda retains the same 400mm ground-effect fan as the T.50, but here it runs in a single High Downforce mode, spinning at 7000rpm. The T.50s also has much simpler ducting, with a permanently open duct running down to the redesigned rear diffuser.
Like the chassis, the T.50s Niki Lauda’s aerodynamics can be adjusted to suit its owner’s preferences, adding or removing downforce as required. To balance the car’s aero, the front diffusers are adjustable, as is a slotted flap on the rear wing. The high-speed balance can be further honed through changes to the car’s ride height.
In the optimum configuration, when a particular race circuit demands it, up to 1500kg of downforce will be achievable. However, the car’s aerodynamics have been carefully designed to ensure that the T.50s Niki Lauda’s performance remains accessible and exploitable regardless of the driver’s experience.
