Engine
The heart of every racing car is undoubtedly its engine. The sound of a racing engine revving at full load is enough to make the hairs on the back of any racing fan's neck rise. When the engine wails, the discerning ear can tell how many cylinders the car has and eight-cylinder V-formation engines have been the favourite of drivers and engineers for years.

The all-new A1 Engine, code-named ZA1348, was developed specifically for the A1 Car by the team at Zytek Engineering.

A 3.4-litre V8 unit developing 520 bhp (550 bhp in PowerBoost mode), Zytek used its considerable expertise in theoretical analysis and practical experience to design the unit. It's got advanced electronic fuel injection, quad cams and four valves per cylinder to ensure exceptional fuel delivery even under high lateral g-forces.

Each A1 Engine will be powerful, flexible and durable - the engine block will last all season. Made of aluminium alloy, the engine block and head deliver the performance of a heavyweight in a flyweight package.

Despite its immense power the new engine weighs only 120kg - making the A1 Engine one of the lightest 3.4-litre racing engines ever made.

Safety Equipment
For A1 drivers, the A1 Car is a safe environment in which to race. In addition to the car meeting all the stringent FIA crash tests, the driver can also count on several features within the cockpit. This includes a HANS (Head and Neck Support) device installation.

A special extractable seat moulded to the driver's exact shape allows easy removal of the seat and driver if necessary, and a padded headrest made from state-of-the-art Conforfoam protects the head from rapid g-loading changes

Transmission System
Ask any engineer, and the ability to reliably transmit up to 550 bhp and 442 Nm through a lightweight unit is hard to achieve.

Transmission suppliers worked with Lola International and Zytek Engineering to develop and refine the A1 Car's six-speed sequential gearbox.

The gear pack is mounted sideways giving better weight distribution and allowing very compact overall dimensions.

The gearbox casing is made of magnesium alloy, famed for its strength and light weight while the gear wheels are straight cut steel alloy.

Suspension
The front and rear suspension is of double wishbone and pushrod operated twin coil over damper construction. Adjustable ride height, cambers and toe, as well as anti-dive and anti squat will optimise drive control.

[JK.]

Chassis
The chassis can literally make or break a racing car, and the A1 Car boasts one of the very best.

Made and designed by Lola International, the A1 Car has a carbon fibre skin which cloaks a core made of aluminium honeycomb.

Based on bionic engineering principles found in nature, the hexagonal honeycomb gives remarkable strength for its weight, and has progressive deformation properties when experiencing an impact.

The aluminium honeycomb core works exceptionally well in racing cars. Combined with the carbon skin it gives a one-piece safety cell 'tub' which displays incredibly torsional rigidity (resistance against twisting).

Driver protection is ensured with FIA-approved side intrusion panels which protect from lateral impacts.

[JK.]

Oil and Coolant Systems
The engine and gearbox oil and coolant systems were tested extensively in the Lola windtunnel to withstand 35 degrees Celsius ambient, in effect simulating running in a hot and dusty environment.

The lubricant is Mobil 1 fully-synthetic, and is used in the A1 Car's dry sump.

Paddle Shift
The EGS is an electro-mechanical system, which has been completely designed and manufactured by Zytek Engineering for use in the A1 Car. The system is the first of its kind to be developed for use in motorsport and utilises the very latest CNC machinery and bespoke manufacturing processes to ensure every unit is made to the same exacting quality standards.

The Electronic Gear Shift System (EGS) allows gear shifting with sequential gears by the actuation of shift paddles, which are mounted onto the steering wheel. The right-hand paddle shifts up a gear, the left shifts down. Additional switches, for selecting neutral and reverse, are also mounted on the steering wheel.

The driver does not need to operate the clutch, except for starting and stopping and when selecting neutral and reverse gear. The EGS offers down change protection which eliminates the possibility of engine over-revs, and it also has the additional benefit of 40millisecond gear changes (about the same time as it takes to blink) and up to four downshifts in less than a second which considerably increase the life span of the gears and dog rings.

The EGS system consists of the following components:

GCU
Up Shift Actuator
Down Shift Actuator
Blipper Actuator
Steering Wheel Components (including)

- Up Shift Switch + Paddle Assy (one only)
- Down Shift Switch + Paddle Assy (one only)
- Neutral Switch
- Emergency Switch
- Reverse Switch



PowerBoost
The PowerBoost system adds a whole new dimension to international motorsport and is unique to the A1 Grand Prix series. By changing the engine's parameters, the system can give the driver an additional 30bhp over a limited time during each race. Taking the A1 Race Car to its maximum 550bhp, when used at the right time, the PowerBoost will encourage overtaking meaning the race leader could change on a lap-by-lap basis making even more exciting racing.

Driver activated by a button mounted on the steering wheel, the PowerBoost function will only work if the button is pressed when the throttle is above 80% and the car speed is above 60Kph. The button has to be kept pressed to keep the PowerBoost activated but the system will automatically deactivate if the throttle position drops below 40%. Each driver will have a limited amount of time that he can obtain the extra power, four activations for each Sprint race and eight activations for each Feature race. Once this allotted time has been used the system will become disabled, after each race the Zytek engineers will then re-set the system on each A1 Race Car ready for the next race.

Each driver will need to use his skill to carefully manage how and when the system is used during the race.

Fuel System
The A1 Car is equipped with a 135-litre capacity ATL flexible fuel cell. The capacity allows the races to be completed without the need to re-fuel midway.

Two lift pumps including one high-pressured system give a colossal flow rate of 200 litres per minute. The fuel cell is made from Kevlar-based FIA spec FT-5 material, similar to that used for bullet-proof vests.



Dampers
By its very nature, a racing car's suspension needs to be taut and stiff, to enable it to take corners at phenomenal speeds. This tautness means the suspension's travel is limited and as such any system needs to offer fine-tuning and adjustment.

Suspension experts Ohlin's well-respected TT44 dampers (commonly known as shock absorbers) have been used in the A1 Car from day one, and offer three-way adjustability to fine-tune each car's set-up to the needs and preferences of individual drivers.

The dampers have been thoroughly tested on Lola's seven-post dynamic test rig, which simulates the suspension conditions at various racetracks both before and after track test sessions. Ohlin dampers are made to a consistently high standard, ensuring all 25 A1 teams have parity and equality in their suspension equipment.

The rest of the front and rear suspension is of double wishbone and pushrod operated twin coil over damper construction. Adjustable ride height, wheel cambers and toe in/out, as well as anti-dive and anti-squat will optimise the driver's control. In short, the A1 Car's suspension set up can be tailored to be as unique as the driver's fingerprints.

Francia tiene a alexander Bramet, que el año pasado arraso en dicha categoria, pero quisas este mas concentrado en GP2 o en F1.

Lastima que no la transmitan, ojala y fox lo hiciera como hace con la GP2.

Saludos

[rickdohc]

por mas petrodolares q le metan a esa categoria... dudo q llegue siquiera al nivel de una gp2

para mi .. es la MLS del futbol

salu2
