Se pare ca o vom vedea pilotata de catre Dario Franchitti chiar in acest an la Le Mans, unde L'Automobile Club de L'Ouest (organizatorul celebrei "24 Heures du Mans") a modificat regulamentul pentru a permite Highcroft Racing sa concureze cu DeltaWing plecand de pe ultimul loc pe grila (56), "hors concours".
Atentie, nu uitati ca masina a fost proiectata sa aiba aceleasi prestatii ca cele ale concurentelor, dar cu greutate, putere si consum reduse la jumatate...

KEY TECHNICAL FEATURES:
Engine and transmission are “non-stressed members” in the chassis structural design which allows the installation of a wide variety of lightweight powertrains.
The car features a 4 cylinder 1600cc liquid intercooled turbocharged engine that will produce approximately 300 horsepower at 8,000 rpm and weigh 70kg.
Transmission is a 5 speed plus reverse longitudinal design with electrical sequential paddle shift actuation. The differential features an efficient variable torque steer/differential speed-controlled planetary final drive reduction layout with the entire transmission weighing only 33kg.
Vehicle weight distribution is necessarily more rearward than traditionally seen with 72.5% of the mass between the wide track larger rear tires.
76% of the aerodynamic downforce acts on the rear of the car which has a lift to drag ratio of >5.0.
Rear wheel drive coupled with the rearward weight and aerodynamic distributions greatly enhances inline acceleration capability.
Unique amongst today’s racing cars, more than 50% of the vehicle’s braking force is generated behind the center of gravity giving a dynamically stable response.
Locking propensity of the un-laden front wheel at corner entry is greatly reduced due to virtually no lateral load transfer with the narrow front track/wide rear track layout, steered wheel “scrub drag” moment is virtually zero greatly increasing tire utilization and reducing mid turn understeer.
Advanced computer modeling of structures, impact energy management, aerodynamics, vehicle dynamics and tires has been used to develop the DeltaWing design.
Driver position, restraint layout and energy absorbing structures designed to meet the latest occupant survival criteria.
