This year at the 24 hours of LeMans annual race Nissan was set to prove their
Nissan Deltawing design; There's no telling for certain if the shove came as a deliberate attempt from Toyota to end the Deltawing's race - probably not, probably just didn't see him there.
The driver of the Nissan Deltawing for this years 24 hours of LeMans was Satoshi Motoyama, seen in the video below trying valiantly to get his car started again in hopes to finish the race, unfortunately this car has given up its ghost.

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.
