The Mercedes-Benz SLR McLaren is an Anglo-German grand tourer car jointly developed by Mercedes-Benz and McLaren Automotive, built in Portsmouth and the McLaren Technology Centre in Woking, Surrey, England and sold from 2003 to 2009. When it was developed, Mercedes-Benz owned 40 percent of the McLaren Group.
Due to the automatic gear box, front mid-engined arrangement, and its driving characteristics, some commentators classify the SLR McLaren as a GT, whose rivals would be vehicles such as the Aston Martin DBS V12 and Ferrari 599 GTB Fiorano.
SLR stands for "Sport, Leicht, Rennsport" (sport, light, racing). Mercedes-Benz stated that they would build 3,500 SLRs over seven years, with an annual production of 500 cars. The car's base price, GB£295,337 (approx. US$450,000, €350,000, CHF 500,000 or C$ 500,000. 2009), made it the ninth most expensive street-legal car in the year 2008.
The SLR features Sensotronic, a type of brake-by-wire system. The brake discs are carbon-ceramic and provide better stopping power and fade resistance than steel discs when operating under ideal working temperature. Mercedes-Benz claims these discs are fade resistant to 1,200 °C (2,200 °F). The front discs are internally vented and 370 mm (15 in) in diameter. 8 piston calipers are used. Rear discs are 360 mm (14 in) in diameter with 4 piston calipers. During wet conditions the calipers automatically skim the surface of the discs to keep them dry.
To improve braking performance there is an automatic air brake, when engaged the rear elevation angle of the rear spoiler is set to 65 degrees. The additional rear downforce in addition to the markedly increased aerodynamic drag increases peak deceleration ~90%[citation needed].
The brakes have been strongly criticized by such review sources as Top Gear due to lacking modulation and having an on-off operation. This is due to road cars not regularly reaching normal operating temperature for ceramic discs in stop-go traffic conditions.
The SLR features active aerodynamics; there is a spoiler mounted on the rear integral air brake flap. The spoiler increases downforce depending on its angle of elevation (angle of attack). At speeds above 95 km/h (59 mph) the spoiler/brake automatically raises to 10 degrees (15 in 722 edition), when demanded via the driver's switch, the elevation can be increased to 30 degrees (35 in 722 version) for increased rear downforce, at the cost of increased steady state drag, also when the driver applies the brakes the spoiler raises.
The SLR sports a 232 kg (510 lb) hand-built 5,439 cc (5.439 L; 331.9 cu in), supercharged, all-aluminium, SOHC V8 engine. The cylinders are angled at 90 degrees with three valves per cylinder and lubricated via a dry sump system. The compression ratio is 8.8:1 and the bore and stroke is 97 millimetre (3.82 in) and 92 millimeters (3.62 in), respectively. The Lysholm-type twin-screw supercharger rotates at 23000 revolutions per minute and produces 0.9 bar (13 psi) of boost. The compressed air is then cooled via two intercoolers. The engine generates a maximum power of 626 PS (460 kW; 617 hp)@6500rpm and maximum torque of 780 N·m (580 lb·ft)@3250-5000rpm.
Unlike most of its contemporaries, its engine is front-mid mounted. McLaren took the original concept car designed by Mercedes and moved the engine 1 metre (39.4 in) behind the front bumper, and around 50 centimetres (19.7 in) behind the front axle. They also optimized the design of the center firewall.
[edit]Transmission
The SLR uses AMG SPEEDSHIFT R 5-speed automatic transmission with 3 manual modes. For durability Mercedes selected a 5-speed transmission rather than their 7-speed gearbox which was more complex and used more parts.
The car uses carbon fibre for its entire body construction in an attempt to keep the weight low. Despite CFRP materials the total curb weight is 1,750 kg (3,858 lb).
Car and Driver achieved a 0-60 mph (100 km/h) time of 3.4 seconds, and a quarter-mile time of 11.2 seconds at 130 mph (209 km/h) C&D suggests the times may be even lower if temperatures were lower. Motor Trend tested the SLR and achieved a 0-60 mph time of 3.3 seconds in April 2006. Car and Driver achieved top gear acceleration 30-50 mph and 50-70 mph times of 1.7 and 2.4 seconds, which are the fastest ever recorded by the magazine in a production car. The SLR also pulled 1.13 g on the skidpad.
Road and Track tested the car in their July 2005 Road Test and reached 60 mph (97 km/h) from a standstill in 3.5 seconds. The 0 - 100 mph (160 km/h) sprint was achieved in 7.5 seconds and a quarter mile run was completed in 11.5 seconds at 126 mph (203 km/h).
In June 2004 the SLR was tested at Nardo and performed the 0-100 km/h (62 mph) exercise in 3.2 seconds, 0-200 km/h (124 mph) in 9.6 seconds and 0-300 km/h (190 mph) in 24.8 seconds Their 400 m (0.25 mi) time of 11.0 seconds at 133 mph (214 km/h) and 1 km (0.62 mi) time of 19.2 seconds at 282 km/h (175 mph) respectively. They also broke its claimed top speed of 334 km/h by reaching 339 km/h (211 mph).

The Zonda F is the penultimate model of car produced by Pagani .
It was originally named Fangio F1, in homage to the great champion of the ' motoring Juan Manuel Fangio , his compatriot, friend and mentor of Horacio Pagani , the Zonda project is renamed with its current name, the same as a wind Andes, in 1999 , the His debut with the C12 model, at the Hall of Geneva .
Mount the engine Mercedes-Benz V12 engine of 602 hp in the standard version and 650 hp in the Clubsport version, available for both the Roadster Coupe (Clubsport version also has special carbon ceramic brakes and a more sporty set-up) The coupe is credited Clubsport for a speed of 344 km / h, an ' acceleration from 0-100 in just 3.6 'and from 0 to 200 in 9.8' and a braking time from 200 to 0 in 4.4 ', making it one of the fastest cars in the world.
The Zonda F is also offered in version roadster or "clubsport", even more exclusive of the basic model. The prices are particularly high due to the fact that every Zonda is handcrafted with materials such as fiber carbon so prized and very expensive.
The Zonda has been repeatedly tested by Top Gear , a famous British TV show about cars. Currently, the Zonda F has the 4 th and 6 th time in the ranking of the Top Gear Power Laps , respectively, in the version Roadster and Coupe ; during the lap of the roadster version of the recorded time was better than that done by the Bugatti Veyron , and to emphasize the positive "disappointing" the Bugatti, Richard Hammond called the Zonda F as a parody of a supercar.

Horacio Pagani ( Casilda , 10 November 1955 ) is a businessman Argentina , owner of Pagani Automobili .

Horacio The small son of a baker of Piedmontese origin (paternal grandfather emigrated to Argentina in the late 800), was born in a small town in Argentina and from an early age of 12 he began to build models of cars with materials luck.
At just 20 he made ​​his debut in the world of racing cars, making a car Formula 3 that competed in Argentina with the official team colors of Renault .
The encounter with the driver Juan Manuel Fangio 's life changes and helps him to get close to Modena . When, in 1982 , arrived in Italy the first activity is to metalworker third level. Before going into business with the creation of his automobile in San Cesario sul Panaro , has worked with design teams of Lamborghini Diablo , the P140 and L30 (the Countach Anniversary ).
His dream to create his own supercar began in 1988 with the "C8 Project" and the name initially chosen for the prototype is Fangio F1 but when the car was completed and approved, will be presented at the Geneva Motor Show of 1999 , Fangio was already dead and then gives the name of Zonda its creation by the name of taking the wind that blows over the Andes .

bugatti veyron
[hidden link - please register]

The Bugatti Veyron is a luxury high-performance super car produced by the automaker French Bugatti .
The Veyron (or more precisely, the Bugatti Veyron 16.4 ) is known to be one of the most expensive production car in the world during the production period (1.1 million euros before taxes for the "basic" version), and has been at the launch ' car fastest production ever built, with a speed of up to 408.47 km / h [1] . He kept the record until 13 September 2007 , when the SSC Ultimate Aero TT has established a new record of 412 km / h, then the record was taken from the same Bugatti in June 2010. It is hand-built Bugatti factory in Molsheim in France, where the company was located originally founded by Ettore Bugatti , and has reached full production, in September 2005 in a limited edition of 300 copies.
Named after the driver Pierre Veyron , who won the 24 Hours of Le Mans in 1939 racing with a Bugatti .

The design of this vehicle began in 1999 with the concept car, EB 18 / 3 "Chiron" . Shown at the Tokyo Motor Show, was similar to the final version came later in production, one major difference was the EB 18 / 3 used a motor W18 with three cylinder banks of six cylinders. The final version of the Veyron was designed by Hartmut Warkuss , the Volkswagen , instead of Giorgetto Giugiaro, who had edited the first three prototypes .
The Volkswagen , which owns the brand Bugatti Veyron announced the production of in 2001 at the Motor Show of Geneva . It was announced that would be the fastest, most powerful and expensive car in history: the statement promised more than 400 km / h top speed, 1001 hp of power and a price round of 1 million euros .
The project continued in 2001 with the "advanced concept" EB 16 / 4 Veyron W18 engine which replaced the 3- cylinder banks of the Chiron W16 with a 4-cylinder banks, seen for the first time in 1999 on the concept car Hunaudières Bentley . In late 2001, Bugatti announced that the car would be officially called Bugatti Veyron 16.4, with reference to 16 cylinders and 4 turbochargers, and that would be in production in 2003 . However tests revealed significant problems: the stability was too low to high speeds, so that a prototype was destroyed, while another went out of control during a demonstration at the Mazda Raceway Laguna Seca (thankfully few consequences for the pilot). Even during a test in Germany Veyron caught fire due to overheating of the engine, which was a major problem to be solved under development, mainly because of the particular structure of the W engine which makes it difficult to cool. Other problems encountered during testing were hampered by improving the tires and the need for dedicated, by the particular strength, because the high power of the car caused a premature wear of the normal high-performance tires. After two years of waiting all these problems were solved, and in 2005 , two years late, began deliveries.
The developmental delays caused controversy even with the buyers: the Bugatti had begun to take orders for the Veyron, while development was still underway and the start of production was fixed at 2003 . So buyers, according to the conditions that had paid a down payment of 300,000 euros and could not withdraw the deposit without losing the order, had to wait a couple of years longer than promised to deliver, waiting for the company solve the mechanical problems insurgents and start production.
Introduced at the price promised 1 million euros, offered a guarantee of 50,000 km or 2 years, laughable half of this lineage, but justifiable in the face of the big problems of reliability which has been shown. From 1 April 2006 the price of the coupe has risen to 1.1 million euros while maintaining the same contractual conditions. For all maintenance is also necessary to bring the car to the factory in Molsheim in France.

The Veyron features a W16 engine of 7,993 cc of displacement (86 mm for bore x 86 mm stroke ), with 4 banks of 4 cylinders each. Each cylinder has 4 valves , for a total of 64. The engine has 4 turbochargers , by which delivers 1001 hp of power at 6,000 maximum claimed speed / minute [2] , with a power to weight ratio of 529 hp / t , the torque maximum of 1,150 Nm at 2200 revs / minute. The design of the W16 is actually derived from the W8 mounted on the fifth series of the Volkswagen Passat , whose unit cylinder (ie the displacement of each cylinder) corresponds to that of W16.
The engine power is transmitted to the wheels through a gearbox type DSG to 7-speed simultaneous grafts, implemented by paddles located behind the steering wheel, the gear shifting time is 150ms. This was achieved thanks to a dual exchange rate system, particularly parallel: all the time in practice two gears are engaged simultaneously and provides a dedicated microprocessor to trigger the motor shaft to the proper progression of speed. Traction is fully permanent, with a viscous coupling center produced by Sweden's Haldex. The tire run-flat products from Michelin are specifically designed to withstand the maximum speed of the Veyron, and have the unusual measure of 245/690 R20, 47 R21 365/710 and front, 26 rear. A set of tires lasts an average of 9 thousand kilometers and cost approximately 15 thousand euros.
The Veyron has a total of 10 radiators :
3 for the engine cooling system
1 heat exchanger for the intercooler
2 for the air conditioning system
1 for oil in the transmission
1 for the oil differential
1 for the engine oil
1 for the hydraulic system of the spoiler
The coefficient of drag (Cd) is 0.36. The frame consists of a central cell with carbon fiber subframe.
The brake discs are made ​​of carbon-ceramic , with clamps 8-piston front and rear 6 piston. A curiosity is that for the engine is located directly in the open air, with no glass cover, to maximize heat dissipation. During the test phase, the engine comes to actually produce 3 thousand horsepower, of which two thirds are dissipated as heat is the reason why during the initial tests the air conditioning system of the bench tests was set on fire in the whole plant, as reported by the same design engineers in an interview reported by a documentary produced by National Geographic Channel on the Veyron.
In the instrumentation of the speedometer is installed next to the Veyron a power meter, which indicates the horses are actually delivered in all driving conditions (limited to 1001 and limit advertising, having already said that the maximum power of 1060 hp).
The promised top speed was 406 km / h , but the prototype proved to be unstable at that speed: it was necessary to redesign the model to improve the ' aerodynamics . In May 2005 a prototype tested in the circuit Vokswagen near Wolfsburg , Germany , reached a speed of 400 km / h, electronically limited. In October 2005 the final version of the Veyron, driven by James May , it reached 407.52 km / h on the long straight (9 miles) of the German circuit in Ehra-Lessien, owned by Volkswagen .
The Veyron accelerates from 0 to 100 km / h in 2.5 seconds , producing an acceleration average of 1.01 g : a record of approved cars, faster than even the SSC Ultimate Aero TT with four-wheel drive. Reaches, always stops, 200 and 300 km / h in 7.3 and 16.7 seconds respectively. Note that the Veyron reaches starting from a standstill to 200 mph in less time than it uses the McLaren F1 starting from 120 miles: this makes the Veyron the car with the best road acceleration of history. In a test of the British magazine Autocar has made ​​the Veyron on the test 0-100 mph -0 (acceleration 0-160 km / h and stop sign) in 9.9 seconds, a record time. Although consumption is a record for production cars: it keeps track of the Veyron 40.4 l/100 km (2.475 km / liter) in city and 24.1 l/100 km (4.149 km / s) on the mixed circuit. Consumption at the maximum speed is over 125 l/100 km (0.8 km / l): In this condition, the Veyron's tank (100 l) would be emptied in just 12 minutes and a half (in which time would be able to go over 80 km).
Reached 220 km / h Veyron change of attitude: the car is lowered while the spoiler rises to increase rear grip. In standard configuration the car is capable of a maximum speed of 375 km / h. To achieve a maximum speed of 407 km / h, you should enter the car is stopped a second key slot in a red color to the left of the driver, close to closing the door: this command via the rear spoiler minimizes the ' corner incidence of returning to his seat, the front air intakes are closed and the car is lowered by 6 cm to a minimum by limiting the impact of aerodynamic downforce, but also, that adversely affects the stability.
The record-breaking data on deceleration. The carbon-ceramic brakes, along with very high performance tires, allow to achieve a deceleration of 1.3 g . In addition, when the brakes are operated at speeds above 200 km / h, the spoiler increases rear ' incidence angle up to a maximum of 55 degrees in 0.4 seconds, by acting as aerodynamic brakes , and generating, by itself, 0 , 6 G deceleration, (a solution similar to that of the Mercedes McLaren SLR ). With the addition of these elements, the Bugatti Veyron said that the maximum speed can stop in less than 10 seconds, despite the mass close to 2 tons.
