2010 Arash AF-10
Arash Sportscars was born out of the passion for cars, the enchantment of beauty and the thrill of driving the seemingly endless acceleration of a thoroughbred engine. The engine or shall we say the soul of the car is designed to withstand the punishment of motor racing, and we're sure will excite even the most accomplished driver. The superlative handling of a chassis designed by leaders in theor field, and braking performance so forceful you question whether the tyres will still be intact when you climb out. And whether you're approaching or leaving a silhouette that seduces and excites. From a dream to concept, and from concept to reality, Arash Sportscars no longer exists as a dream, it is a reality.
Arash Cars was established in March 2006 and has been working on the AF10 ever since. The styling drawings were made in March 2005 by Arash Farboud Designs and have since been converted into computer models and aerodynamic cfd mesh models. The company is located in Sawston on the outskirts of Cambridge. Most testing will be conducted at Millbrooke proving grounds 20 miles away from the company. The facility in Sawston Cambridge is equipped with a styling studio, painting booth, carbon lamination room, parts despatch area, carbon curing autoclave oven and polished epoxy floored car assembly stations. A board room and administration offices are also located at the site. Arash Cars have designed a traditionally shaped badge with an eagle emblem. The background colour is solid black and the foreground eagle is in gold. The 'Arash' emblem is in flame orange.
100% carbon construction using aluminium honeycomb and nomex panels for sandwhich strength. Rear window and driver to engine compartment window made of non shatter and scratch resistant plastic. Front windows and side windows are constructed of laminated glass. All body parts have been constructed using the carbon autoclave process of eliminating excess resins via pressure and heat to make parts lighter and stiffer than ever constructed.
Modular Carbon Chassis - super light, super strong and reduced manufacture time and cost. Patented design of modular construction. 13 parts assembled into a jig and bonded at temperature. Accurate dimensions as well fantastic performance as a stiff and strong chassis for driving. 98kg weight of tub. steel sub structures front and rear. Excellent protection from crash - front and rear sub assemblies. Rear impact bars and side rear impact struts. Side panels of chassis overlooped to provide triple protection. Triple galleries under chassis - allows tidy packaging of water pipes, air conditioning pipes and brake lines. Prevents heat travelling into driver cabin and allows easy access for inspection. Fuel tanks integrated into rear chassis pontoons. Ideal for weight distribution and crash compliance. Simulation tests have been made using computer generated crashes and twists to see how the carbon tub and sub assemblies cope with extreme loads.
The brakes are Carbon ventilated Ceramic Discs 8 Cylinder AP Racing Calipers. And are 380mm Disk Diameter at the front. and Ventilated Ceramic Discs 6 Piston AP Racing Calipers 362mm Disk Diameter at the rear. The lightweight wheels are made from 2-Piece Aluminium, the front wheels are 48.3 x 24.1 cm / 19 x 9.5 in and the rear wheels are 50.8 x 31.8 cm / 20 x 12.5 in. After various testing on some of the most testing circuits we have chosen Michelin Pilot size 265/35ZR19 for the front and 335/30ZR20 for the rears. Thus adding stability in the wet and dry enabling confidence in all weathers.
The engine features all-aluminium, titanium conrods, forged pistons and crank shaft. Hand assembled engine by General Motors USA Michagan. 550bhp and 555nm torque. Exceptional power from a lightweight unit. Emissions one of the best in the world. 7 litre capacity. Dry sumped, separate oil cooling and fly by wire throttle.
Super long front wishbones and wide wheel track. Avoidance of pushrod suspension to allow more compliant road ride. Move away from pushrod also to reduce number of pulley and rod parts. More compliant ride due to single action of motion rather than elbow action which can cause 'sticking' of bearing parts. Wishbones hand made and nickel coated. Not only prevents corrosion, but also allows visibility of any cracks from wear and damage. Stronger than tests done with castings and machined parts. Allows some flex to give 'predictability' for the driver aswell as 'feel'.
Rubber elastic bushes used for road compliance and ease of assembly. Engine and gearbox also mounted on rubber bushes for vibration avoidance from the driver cabin. Super long lower front wishbones, allowing more contact patch of the wheel during cornering. - see F1 cars. Integrated strut brace within carbon tub to prevent any flex. Roll centre of the car has been moved lower. Floor mounted pedals to offer racing feel, better 'heel and toe' control of the pedals as well as the ability to offer good foot spacing in the driver area. Complete integrated roll cage - a touch of hand made art aswell as the improved stability and stiffness of an already amazingly stiff chassis. Further protection has been offered during crash and roll incidents.
