Se pare ca o vom vedea pilotata de catre Dario Franchitti chiar in acest an la Le Mans, unde L'Automobile Club de L'Ouest (organizatorul celebrei "24 Heures du Mans") a modificat regulamentul pentru a permite Highcroft Racing sa concureze cu DeltaWing plecand de pe ultimul loc pe grila (56), "hors concours".
Atentie, nu uitati ca masina a fost proiectata sa aiba aceleasi prestatii ca cele ale concurentelor, dar cu greutate, putere si consum reduse la jumatate...

CAR SPECIFICATIONS:

Vehicle weight: 475kg
Brakes: Carbon discs and pads
Horsepower: 300 BHP
Fuel cell capacity: 40 liters
Wheel base: 2.9 m
Chassis construction: lightweight composite
Aerodynamic drag: Cd 0.24
Front tire: 4.0/23.0 R15
Front track: 0.6m
Rear tire: 12.5/24.5 R15
Rear track: 1.7m
Weight distribution: 27.5% Front / 72.5% Rear
O/A length: 4.65 m
O/A width: 2.00m
Height: 1.03 m

KEY TECHNICAL 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.

In contextul actual, masina sport a secolului XXI mi-o imaginez ca fiind ieftina de produs. Ar fi fost bine daca in caietul de sarcini al echipei ar fi fost si cerinta asta : sa construiasca o masina cu performate similare cu ale concurentilor dar la jumatate de pret !

Da si nu prea...
Masinile de curse nu au fost niciodata ieftine :wink:

Prima aparitie in public si primul video.

La Sebring a fost cu 10 sec mai lenta ca Audi, cu multe sisteme dezactivate, probabil asta o sa ii omoare, lipsa testelor si a know-how-ului pentru integrare. Eu sper macar sa termine cursa, desi imi aduce aminte serios de asta http://www.motoczysz.com/motorcycles/c1_prototype" onclick="window.open(this.href);return false;

Din pacate aventura de la Le Mans s-a incheiat devreme : video. Eu chiar ma intrebam ieri cum ar fi ca masina asta cu motorasul ei de 1.6 sa termine cursa, si inca pe un loc bun. :scratch:
De apreciat pilotul samurai ce nu vroia sa se lase batut !

Din pacate aceste tipuri de masini nu au fost create pentru marele public...
