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.
