A1GP cars
This is an overview of all racing cars in the A1GP series.
Lola-Zytek
The Lola - Zytek was used in the A1GP seasons 2005/2006 , 2006/2007 and 2007/2008 .
The car completed its first test drives in August 2004 and was driven by Stephen Watson and Ralph Firman ; The latter also took over the further test work. Jonny Kane was behind the wheel of the E30 fuel's engine compatibility test runs before the third season .
Dimensions
The car has a length of 4833 mm, is not wider than 1930 mm and has a maximum height of 1056 mm. The wheelbase is 3000 mm and the track width is 1476 mm at the front and 1468 mm at the rear. It has a weight of 695 kg.
Chassis and Components
The chassis designed and manufactured by Lola International consists of sandwich panels with a honeycomb core made of aluminum with outer layers made of carbon fiber reinforced plastic . It is equipped with special panels to the left and right of the cockpit, which are intended to protect the driver from a side impact. The individual vehicle parts, such as the front and rear wings, are made from carbon fiber prepregs , which are semi-finished products made from carbon fiber fabric impregnated with synthetic resin that is hot end-processed in press molds, i.e. not a laminate . The car has a transverse six-speed sequential gearbox developed by Lola in collaboration with X-Trac . The gear housing is made of magnesium, the straight-toothed gears are made of a steel alloy. The entire gear complex is built in on the side to ensure better weight distribution and greater compactness. The individual gears are engaged with a rocker switch on the steering wheel, which Zytek Engineering is responsible for developing . The steering wheel manufactured by Sparco has a diameter of 280 mm, a digital display and a flattened shape that is typical for today's motorsport conditions. It acts on the pinion of the rack and pinion steering, the car is fitted with AP - disc brakes with four-piston calipers. The wheels are suspended from double wishbones at the front and rear and the internal springs and triple dampers are actuated by push rods.
engine
The by Zytek Engineering developed specifically for this car 3.4 liter - V8 engine is labeled ZA1348 . It generates an output of around 382 kW (520 hp), whereby 30 additional hp can be activated with the so-called PowerBoost button. The engine block is made of an aluminum alloy. The engine contains electronic manifold injection , four camshafts and four valves per cylinder and weighs just 120 kg. Its durability is calculated so that two engines are enough to survive a complete season.
Fuels and lubricants
From the beginning of the first season up to and including the Zhuhai race weekend in 2007, unleaded gasoline with an octane number (RON) of 100 was used as fuel. From Taupo 2008 until the end of the third season, the more environmentally friendly fuel Hiperflo ™ E30 was used. This consists of 30 percent ethanol , which is obtained from sugar beet grown in Europe . The aim was to reduce CO 2 emissions by 21 percent and to lower nitrogen oxide emissions ( see A1GP # Ecological Approaches ).
As a lubricant for the dry sump lubrication was synthetic oil from Mobil 1 used.
tires
The tires for the car were made by Cooper Tires . They were available in two specifications: as treadless dry tires ( slicks ) and as rain tires . The rubber compound and profile of the latter has been adapted so that they meet the requirements of both monsoon-like rainfall and those on drying routes.
The wheels are supplied by OZ , they have twelve spokes. The front wheels are 11.75 inches wide and the rear wheels 16 inches; each 13 inches in diameter.
safety
Before the first race the car had the usual crash tests of the FIA through. Among other things, the roll bar was subjected to a load of 7.5 tons and the chassis was subjected to a frontal collision at a speed of 12 meters per second (approx. 43 km / h) and accelerations of up to 60 g . As is usual in higher racing classes, a seat that is precisely adapted to the driver's body and removable in an emergency is used. A headrest padded with Conforfoam is intended to reduce the stress on the head. Furthermore, should the one Sparco - Six-point harness and the now mandatory in the motor sports scene HANS system guarantee the safety of the driver.
aerodynamics
The car was designed by Lola International in such a way that it generates very little “dirty air”. This is intended to enable closer approach to the vehicle in front and thus better opportunities to overtake. The specially developed front wing is intended to reinforce this effect. The flow around the body was first simulated in the computer and then aerodynamically tested in the wind tunnel .
Cameras
The basic equipment of the car includes seven cameras, one of which is placed next to the struts of the front wheel suspension (towards the front, creates a flat view of the route), on the edge of the cockpit (towards the rear, directed towards the driver), in the roll bar (towards the front, classic view ), over the driver's shoulder (to the front, into the cockpit) and below the rear wing (to the rear) and two on the sides of the rear wing (to the front). Over the course of the seasons, new camera positions were tried out again and again, for example there was a “motorized camera” at the 2007 race weekend in Zhuhai.
Accelerations of 3.5 g and top speeds of up to 290 km / h can be achieved with the car . It accelerates from 0–100 km / h in under four seconds.
Auto GP
The Lola-Zytek has been used in the Auto-GP series under the name Lola B05 / 52 since 2009 - with a new rear and front wing, a new fin in the area of the engine cover (now type "shark fin") and Michelin tires .
A1 Ferrari
The A1 Ferrari was used in the 2008/2009 A1GP season . The chassis was developed and built in a factory in Bognor Regis (Great Britain) under the direction of John Travis , the technical director of the series, and with the support of former Ferrari designer Rory Byrne, based on Byrne's last Formula 1 car, the Ferrari F2004 , with which the team from Maranello was able to win the drivers and constructors' world championships in 2004 .
At the end of May 2008, the A1 Ferrari went through its first shakedown. In the following four months before the start of the season, it was subjected to extensive test drives, with Andrea Bertolini , Thomas Biagi , Patrick Friesacher , Marc Gené , Jonny Kane and Danny Watts as test drivers.
Dimensions
The car is 4814 mm long. It has a wheelbase of 3100 mm and track widths of
2014 mm (front) and 2028 mm (rear) - each with tires - and weighs a maximum of 695 kg with the driver but without fuel. The ground clearance is 27 mm.
Chassis and Components
Sandwich panels with a honeycomb core made of aluminum and cover layers made of CFRP also serve as the basic framework for this chassis. Attachments such as the front and rear wings are made of lightweight composite materials. The sequential six-speed gearbox is installed lengthways and acts on the drive shafts via tripod joints . The steering wheel is comparable to that of the Lola bolide in terms of its equipment and appearance - with a digital display and a diameter of 280 mm. The disc brakes with brake discs made of carbon fiber reinforced ceramic and six-piston calipers made of aluminum were supplied by Brembo . The two-way adjustable VBP-45 dampers come from Penske . The ATL fuel tank has a capacity of around 150 liters and is designed to hold fuel with up to 50 percent ethanol. The three clutch plates are made of carbon fiber reinforced carbon with a steel hub from AP .
engine
The 90-degree V8 engine developed by Ferrari SpA has a volume of 4500 cc. It generates an output of approx. 600 PS (448 kW) when the PowerBoost button is activated. The engine has four overhead camshafts, four valves per cylinder and gasoline direct injection . The cylinder block was manufactured using die - cast aluminum , the cylinder head using sand casting. It is 666.5 mm wide, 446 mm high and 569 mm long. It weighs 160 kg and generates a torque of 550 Nm. Its spark plugs come from NGK , the engine management is handled by the Bosch MED 9.6 engine control unit .
fuel
The fuel is E10 petrol from Shell with an octane number (RON) of 102.
tires
The tires for the car are produced by Michelin . They are produced in two versions: as slicks and as rain tires. The front tires weigh 10.3 kg and the rear 11.4 kg, with the rear tires being a bit narrower and therefore a little lighter (11.2 kg) for rainy conditions.
The front wheels are 12 inches wide and the rear wheels are 14 inches wide; each with a diameter of 13 inches.
safety
The car has been tested for all applicable FIA accident safety standards. The driver's safety is to be guaranteed by a six-point belt from Sabelt in combination with the HANS system.
aerodynamics
The design is based on that of the Formula 1 Ferrari F2004 - with the advantages and disadvantages of the aerodynamic configuration at the time. However, in the wind tunnel studies, care was taken to maximize the downforce of the car and thus enable it to be followed more closely, especially in curves, without losing too much of its top speed.
