The Koenigsegg CCX supercar is one of Europe's premiere racing cars, but it is only available for consumption by those who have the ability to shell out the money needed for such an expensive, yet luxurious purchase. The Competition Coupe X is one of Koenigsegg's latest exotic car creations, all of which are known to be some of the best speed cars in the world. Koenigsegg sports cars are not available for mass consumption, mainly due to the large price of such automobiles. Base price is $540,000 + taxes, while fully equipped supercar costs $600,900 + taxes. The Koenigsegg CCX is a great purchase for those who can afford it, due to the fact that it is the tenth anniversary issue of the 1996 CX supercar model, which is one of Koenigsegg's best creations.The supercharged V8 806 bhp @ 6,900 rpm (redline at 7,600 rpm) engines inside 1,180 kg (2,691 lbs) Koenigsegg CCX exotic cars are specially created for the people who design the Koenigsegg CCX though the design is highly based off of the Ford Modular engines, which provide other foreign companies with some of the best engine templates available. The engine is very compatible is various fuel types, and is able to run via gasoline and other bio-fuels, which are proving to be highly marketable, as well as the cars that can accommodate such technological advances. It is fully compliant with California emission regulations and is a street-legal motor. Koenigsegg CCX prides itself on being one of the best producers of tough, speedy cars, while also trying to adhere to environmental procedures that are growing with the high fuel prices and a stricter outlook on global warming.The Koenigsegg CCX is the world's fastest car with a V8 engine, and has consistently won awards from various institutions all over the world, not only for its design and ability to operate at high speeds, but also for the ability of the people at Koenigsegg CCX to keep reinventing their product in a way that helps other philanthropic organizations. The Koenigsegg CCX is a great supercar to commemorate the tenth anniversary of the CX, while still being a great car independent of any others. 


Development
Koenigsegg began the CCX project with the aim of entering the world market, though particularly the United States car market. Development engineer Magnus Jaasund said "We wanted to go into the world market, but we couldn’t do it with the old car." To sell cars to the North American market many alterations were made to the design of the CCR; the previously used Ford Modular engine was replaced by a Koenigsegg engine designed to run on 91 octane fuel, readily available in the United States, and to meet the Californian emission standards.Interior.The front bumper of the CCX is designed to be safer in low speed collisions than previous Koenigseggs and the whole body is 3.46 in (88 millimeters) longer to comply with the United States' rear impact regulations. Additionally the CCX can display United States or European number plates.The CCX is 1.6 in (41 mm) taller than the CCR and, combined with the carbon fiber reinforced plastic sports seats by Sparco, the CCX allows for 2 in (51 mm) of extra headroom that Autoweek reviewer Mark Vaughn hypothesizes is "to accommodate U.S. NBA stars." The electronic control unit has also received an upgrade over the CCR meaning that the CCX is without physical fuses and it is lighter than the previous system.
Engine
Previous Koenigsegg models were powered by Ford Modular V8 engines sourced from the U.S. Though also based on the Ford Modular architecture the engine of the CCX was thoroughly re-engineered by Koenigsegg themselves and is assembled at the Koenigsegg factory. The engine block for the dual overhead camshaft, 4 valve per cylinder 4.7 liter 288 cu in (4,719 cc) V8 is cast for them by Grainger & Worrall, a British company that produces drivetrain components for Formula One cars. The engine block is made of 356 Aluminium that has undergone a T7 heat treatment, a form of accelerated precipitation strengthening. The aluminium alloy is stronger than the previous engine and allows a thinner, thus lighter, engine block that will withstand higher cylinder pressures. The engine is boosted by two centrifugal superchargers that provide 17.5 psi (1.2 bar) of boost with an 8.2:1 compression ratio. The engine produces 806 bhp (601 kW; 817 PS) at 6900 rpm and 678 lb·ft (919 N·m) of torque at 5700 rpm on 91 octane (U.S. rating) gasoline.[1] The engine is lubricated with a dry sump system with a separate oil pump, the pistons are cooled by oil sprayed onto them and the oil itself has an external cooler. The CCX does 14 mpg (17 l/100 km) in combined cycle and 18 mpg (13 l/100 km) in highway travel.
Exterior
The CCX is a two-door targa top and the removable roof can be stored under the front trunk meaning that, unlike many of its competitors, it can be changed at any location, not only one where the roof can be safely left. The body, made of pre-impregnated carbon fiber and Kevlar, is 169 in (4,300 mm) long, 78.6 in (2,000 mm) wide and 44.1 in (1,120 mm) tall with a ground clearance of 3.9 in (99 mm). As with all previous Koenigsegg models, the "dihedral synchro-helix" actuation doors rotate forward and upwards similar to scissor doors though the Koenigsegg design avoids the problem of the open door obscuring the passenger's entry or exit.The CCX has a frontal area of 2,894 sq in (1.867 m2) and a drag coefficient of just 0.30. It also has a flat underside with venturi tunnels at the rear and an optional rear spoiler to improve aerodynamics. Between the 2 speedster humps (humps behind the seats) is a vortex generator used as a ram-air intake that allows higher pressure in the air box without a roof scoop that would increase the frontal area. At 124 mph (200 km/h) there is 132 lbf (60 kilograms) of downforce over the front axle and 143 lbf (65 kilograms) over the rear.
Wheels and brakes
The standard CCX wheels are Koenigsegg's magnesium alloy wheels, though the option to upgrade to carbon/magnesium wheels which each weigh 6.6 pounds (3.0 kg) less than the standard wheels is available. The front wheels have a diameter of 19 inches (480 mm) and the rear, 20 inches (510 mm). Each of the wheels is attached by center locking wheel nuts. The car comes with Michelin Pilot Sport 2 unidirectional tires with asymmetric tread. The front tires have codes of 255/35 Y19 and the rear 335/30 Y20.The front and rear cast iron disc brakes are 14.3 in (360 mm) across with 1.3 inches (33 mm) of contact at any point and have 6 piston calipers. The brakes can be upgraded to SystemST carbon ceramic brakes which weigh 4.4 pounds (2.0 kg) less per wheel, a diameter of 15 in (380 mm) with 1.3 in (33 mm) of contact and eight piston brake calipers.

Top Gear
In 2007, the CCX was the fastest car to complete a lap of the BBC Top Gear circuit, in a time of 1:17.6 on the Power Lap, until it was beaten by the Ascari A10 with a time of 1:17.3. The car originally lapped the circuit in 1:20.4, but was then fitted with a non-standard rear spoiler (Subsequently referred to in the CCX's and the Agera's option list as the 'Top Gear Wing') to provide downforce after the show's test driver (The Stig) spun the original version off the track. The Stig purportedly recommended this modification, predicting that the car would then be the fastest ever round Top Gear's track but Koenigsegg later stated that the improvement was due to adjustments to the chassis and suspension settings and not the addition of the rear spoiler.On the power lap board in the show, the "Koenigsegg" brand name in both of the CCX entries were spelled as Koenigseggisseggggnignigsegigisegggg on purpose, as the three presenters claimed they were unable to spell "Koenigsegg" correctly, which causes both of their respective magnetic strips much longer than the other entrants.

With the CCX debut slated for an upcoming debut at the 2006 Geneva Motor Show, we can only hope that Koenigsegg might get sweet revenge. Their supercar, engineered and constructed in Sweden, certainly has the hallmarks of modern design: a carbon fibre monocoque, a supercharged V8 located mid-ship and an inboard, double wishbone suspension.Each CCX is will be specially ordered, and for 2006, Koenigsegg have added a tasty list of new ingredients. Now on menu are carbon fibre wheels and carbon fibre disc brakes which can shed 11 lbs (5 kgs) per corner. Each car comes with a storable hard top and long list of equipment. A 'standard' car is delivered for $540 000 USD, while a fully laden car, like the one in our spec table comes for $610 910 USD.



Bugatti Veyron


Bugatti Veyron
Not just a super car that carries on the name of racing driver Pierre Veyron, who, while racing for the original Bugatti car manufacturer, won the 24 hours of Le Mans in 1939, Bugatti Veyron 16.4 is the second fastest car in the world and the most powerful, it can easily pass as a super hero`s car like Batman. It has the fastest acceleration speed, reaching 60 mph in 2.5 seconds.Endowed with a 8.0L W16-Cylinder, four turbochargers, and a dual-clutch DSG computer-controlled manual transmission, the Veyron can reach a top speed of 253 mph. Counting a sum of 10 radiators, for the engine cooling system, for transmission oil, a heat exchanger for the air to liquid intercoolers, for engine oil etc., the car has a power to weight ratio of 529 bhp/tonne.If we talk about performance we are dazzled by this supercars power to reach 200 and 300 km/h (124 and 186 mph) in 7.3 and respectively 16.7 seconds, wining for herself the name of the quickest-accelerating production car in history. If we count the fact that the top speed of Bugatti Veyron is 253.2 miles per hour (407.5 km/h), a speed limited electronically to prevent tire damage (it can run even faster) we can understand why this spectacular car must consume 40.4 L/100 km (4.82 mpg) when it`s running at top speed and in city driving 24.1 L/100 km.Driven by a superstar like Tom Cruise, this supercar couldn`t name itself cheap, raising the Bugatti Veyron to a price tag of $1,700,000, a price that measures up to it`s quality. Many new designs has been released since 2006, the color might have changed, but the performance and power remain the same.

    
Specifications and performance
The Veyron features an 8.0 litre, quad-turbocharged, W16 cylinder engine, equivalent to two narrow-angle V8 engines . Each cylinder has four valves for a total of sixty four, but the narrow staggered V8 configuration allows two overhead camshafts to drive two banks of cylinders so only four camshafts are needed. The engine is fed by four turbochargers and displaces 7,993 cubic centimetres (487.8 cu in), with a square 86 by 86 mm (3.4 by 3.4 in) bore and stroke.The transmission is a dual-clutch direct-shift gearbox computer-controlled automatic with seven gear ratios, with magnesium paddles behind the steering wheel and a shift time of less than 150 milliseconds, built by Ricardo of England rather than Borg-Warner, who designed the six speed DSG used in the mainstream Volkswagen Group marques. The Veyron can be driven in either semi- or fully automatic mode. A replacement transmission for the Veyron costs just over US$120,000. It also has permanent four wheel drive using the Haldex Traction system. It uses special Michelin PAX run-flat tyres, designed specifically to accommodate the Veyron's top speed, which cost US$25,000 per set. The tyres can be removed from the rims only in France, a service which costs US$70,000. Curb weight is 1,888 kilograms (4,162 lb). This gives the car a power-to-weight ratio, according to Volkswagen Group's figures, of 446.3 metric horsepower (328 kW; 440 bhp) per ton.The car's wheelbase is 2,710 mm (106.7 in). Overall length is 4,462 mm (175.7 in), width 1,998 mm (78.7 in) and height 1,204 mm (47.4 in). The Bugatti Veyron has a total of ten radiators:
    3 heat exchangers for the air-to-liquid intercoolers.
    3 engine radiators.
    1 for the air conditioning system.
    1 transmission oil radiator.
    1 differential oil radiator.
    1 engine oil radiator.
It has a drag coefficient of 0.41 (normal condition) and 0.36 (after lowering to the ground), and a frontal area of 2.07 square metres (22.3 sq ft). This gives it a drag area – the combination of drag coefficient and frontal area, represented as CdA – of 0.74 m2 (8.0 sq ft).


Top speed
German inspection officials recorded an average top speed of the original version of 408.47 km/h (253.81 mph) during test sessions on the Ehra-Lessien test track on 19 April 2005.This top speed was verified by James May on Top Gear in November 2006, again at Volkswagen Group's private Ehra-Lessien test track. May noted that at top speed the engine consumes 45,000 litres (9,900 imp gal) of air per minute (as much as a human breathes in four days). The Veyron has the highest top speed of any street legal production car. Back in the Top Gear studio, co-presenter Jeremy Clarkson commented that most super-cars felt like they were shaking apart at their top speed, and asked May if that was the case with the Veyron at 407 km/h (253 mph). May responded that no, the Veyron was very controlled, and only wobbled a tiny-bit when the air-brake deployed. May further commented “Absolutely yea, it’s totally undramatic. But I would give you a bit of a warning, It’s a bit disorientating doing that sort of speed, because after I came off the banking, I was slowing down to stop, and you know how you get a bit impatient and think ‘I’ll just open the door’, fortunately I looked back at the speedo, and I was still doing seventy.”On 4 July 2010, Bugatti's official test driver Pierre Henri Raphanel piloted the Super Sport edition and was clocked at an average of 431.072 km/h (267.856 mph) on the same track, taking back the title from the SSC Ultimate Aero TT as the fastest production vehicle of all time. The 431.072 km/h mark was reached by averaging the Super Sport's two test runs, the first reaching 427.93 km/h (265.90 mph) and the second 434.20 km/h (269.80 mph). The record run was certified by the German government and the Guinness Book of World Records.The car's everyday top speed is listed at 350 km/h (220 mph). When the car reaches 220 km/h (140 mph), hydraulics lower the car until it has a ground clearance of about 9 cm (3.5 in). At the same time, the wing and spoiler deploy. In this handling mode the wing provides 3,425 newtons (770 lbf) of downforce, holding the car to the road.[11]For top speed mode the driver must, while at rest, toggle a special top speed key to the left of the driver's seat. A checklist then establishes whether the car and its driver are ready to attempt to reach 407 km/h (253 mph). If so, the rear spoiler retracts, the front air diffusers shut, and normal 12.5 cm (4.9 in) ground clearance drops to 6.5 cm (2.6 in).



Braking
The Veyron's brakes use cross drilled, radially vented carbon fibre reinforced silicon carbide (C/SiC) composite discs, manufactured by SGL Carbon, which have a much greater resistance to brake fade when compared with conventional cast iron discs. The lightweight aluminium alloy monobloc brake calipers are made by AP Racing; the fronts have eight titanium pistons and the rear calipers have six pistons. Bugatti claims maximum deceleration of 1.3 g's on road tyres. As an added safety feature, in the event of brake failure, an anti-lock braking system (ABS) has also been installed on the handbrake.Prototypes have been subjected to repeated 1.0 g braking from 312 km/h (194 mph) to 80 km/h (50 mph) without fade. With the car's acceleration from 80 km/h (50 mph) to 312 km/h (194 mph), that test can be performed every 22 seconds. At speeds above 200 km/h (120 mph), the rear wing also acts as an airbrake, snapping to a 55° angle in 0.4 seconds once brakes are applied, providing an additional 0.68 g (6.66 m/s2) of deceleration (equivalent to the stopping power of an ordinary hatchback). Bugatti claims the Veyron will brake from 400 km/h (250 mph) to a standstill in less than 10 seconds, though distance covered in this time will be half of a kilometer (third of a mile)

Engine output
According to Volkswagen Group and certified by TÜV Süddeutschland, the final production Veyron engine produces 1,001 metric horsepower (736 kW; 987 bhp) of motive power, and generates 1,250 newton metres (922 ft·lbf) of torque. The nominal figure has been stated by Bugatti officials to be conservative, with the real total being 1,020 metric horsepower (750 kW; 1,006 bhp) or more.


World's Most Expensive Cars:
Bugatti Veyron Super Sports $2,400,000. This is by far the most expensive street legal car available on the market today (the base Veyron costs $1,700,000). It is the fastest accelerating car reaching 0-60 in 2.5 seconds. It is also the fastest street legal car when tested again on July 10, 2010 with the 2010 Super Sport Version reaching a top speed of 267 mph. When competing against the Bugatti Veyron, you better be prepared!
