Key Technical Features
Engine and transmission are “non-stressed members” of the chassis structural design which allows teams to install a wide variety of lightweight powertrains
The car features a liquid cooled 4 cylinder 1600cc 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 an 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 on the larger rear tires
76% of the aerodynamic downforce acts on the rear of the car which has an 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 vehicles 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 front lateral load transfer with the narrow 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
It's 15.25 FEET long.
