<< Prev Page 2 of 3 Next >>  The Cosworth-designed 3.9-litre V12 engine is a dramatically different version of the engine that powers the T.50. It is even more powerful and faster-revving too, delivering 711PS at 11,500rpm, on its way to a 12,100rpm rev-limit. At 178hp/litre, the specific power output of the T.50s Niki Lauda’s V12 exceeds that of the all-conquering Cosworth DFV Formula One engine. The power-to-weight ratio of 835PS/tonne betters that of a naturally aspirated LMP1 car.The T.50s Niki Lauda’s engine is fed by a newly-designed, roof-mounted, high-performance RAM induction airbox (which can increase maximum power to 725bhp). The maximum torque figure is 485Nm, produced at 9,000rpm. A newly-developed, bespoke, straight-through exhaust system also takes the engine sound to a new level. Right through the rev-range it promises to be one of the greatest and most characterful sounding cars ever made. The state-of-the-art V12 pushes the boundaries of engine design even further, with many new components. Changes include completely revised cylinder heads and camshafts, plus a higher compression ratio of 15:1. Through meticulous attention to detail, this new iteration of the Cosworth GMA V12 weighs just 162kg, 16kg less than what was already the lightest road-going V12 engine ever. The weight-saving measures extend to the intake, exhaust and control systems, as well as the engine itself. All the valves are made from titanium, while there is no variable valve timing due to the additional weight of the geartrain and electronic control system. A simpler induction system features 12 throttle bodies on top of the engine, fed directly by the racing-style air box. The exhaust system does without catalytic converters, has thinner Inconel walls and, with only track noise limits to meet, benefits from smaller silencers. A bespoke Xtrac IGS (Instantaneous Gearshift) six-speed paddle shift gearbox is fitted, designed to fit the exacting packaging and weight demands of the T.50s Niki Lauda. As part of Xtrac’s efforts to minimise weight wherever possible, even the gears are lighter, contributing to a 5kg total weight reduction. Both the gearbox and the clutch are electronically actuated. Ratios have been chosen to optimise on-track performance and driver enjoyment and engagement, delivering a top speed of approximately 200-210mph. A set of closer ratios optimised for shorter circuits will also be offered, allowing owners to make the most of all six gears via the steering column-mounted paddles. In this configuration, the T.50s Niki Lauda will reach around 170mph flat-out. 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 contributes to the 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 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. 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 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 clam shell 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, this 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. Professor Gordon Murray CBE: “When we first ran the CFD we were already ahead of our downforce target. At one point we were achieving 1,900kg of downforce, but we backed it off to 1,500kg to make the car more manageable for the owners.” << Prev Page 2 of 3 Next >> |
