Engine weight: 154 lbs. Oil sump: Machined from Aluminum billet for light weight and to reduce engine height for installation Exhaust system: Inconel 4 into 1 exhaust with external turbo wastegate TRANSMISSION Gearbox: 5-speed sequential Clutch: 2 plate carbon. 4.5" Fuel type: Le Mans Shell E10 - 98 Octane (RON) Shift system: Electrically-actuated direct barrel rotation paddle shift Crown wheel and pinion: Planetary final driver (potentially featuring efficient torque vectoring differential technology in future versions) Driveshafts: Equal length tripod-jointed half shafts CHASSIS Chassis type: FIA homologated carbon fiber monocoque Front suspension: Double-wishbone, unequal length, with coil over shock units to lower wishbones. 4,130 heat-treated thin wall tubular steel welded construction Rear suspension: Double wishbone, unequal length, with pushrod/rocker actuation of coil over shock units. Motion ratio discrimination between heave and roll via fulcrum arm on rear anti roll bar axis Dampers: Coil over hydraulic dampers Anti-roll bars: Torsion bar (rear). No front anti-roll bar Steering: Bevel quadrant steering box without power assist. Rear axle torque vectoring functionality will not be used in race mode Jacking: Air jack Brakes: Vented PFC Carbon/Carbon discs with 4-pot aluminum monoblock calipers Fuel tank FIA-specification gasoline fuel cell Brake bias: 40% torque bias front Brake: Ventilated uprights/air cooled Front brake size: 11" diameter, 0.7" thick Rear brake size: 12.6" diameter, 1" thick Wheels: Forged magnesium 1 piece Front wheel size: 15" diameter, 4" wide Rear wheel size: 15" diameter, 12.5" wide Front tires: 10/31/15 Michelin Rear tires: 310/620/15 Michelin WEIGHTS & DIMENSIONS Weight: 1,045 lbs. without fuel or driver, 1,265 lbs. with fuel and driver Weight distribution (front/rear), % 28/72 Overall length: 15' 3" Front width: 2.5' Rear width: 6' 10" Height: 3' 4.5" Wheelbase: 10' Track width (front) 2' Track width (rear) 5' 8.5" Minimum ground clearance (front/rear) 1-3/16" / 2-3/8" Fuel tank capacity: 10.6 gallons BODYWORK Tub and body panels: Carbon composite Aerodynamics: Twin vortex underbody downforce system – BLAT (Boundary Layer Adhesion Technology) Center of pressure: 25% front, 75% rear Coefficient of drag: 0.35 PERFORMANCE Top speed: 197 mph 0-62 mph 3.3 sec Fuel consumption: Approximately 9 mpg under race conditions 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 # # # Issued by Nissan Files Nissan DeltaWing Specifications LAAS 11-12.pdf (55 KB) Save Remove Download Share Subscribe to Email Alerts Files Nissan DeltaWing Specifications LAAS 11-12.pdf (55 KB)
