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 1.6-liter liquid intercooled turbocharged engine that produces approximately 300 horsepower at 8,000 rpm and weighs only 154 lbs.
- 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
