Knowledge. Brake fade,

Gud morning Guys and Assalam-o-alaikum Hey Guys can u listen me at the back please……Okae fine.

I am AWAIS ALEEM from Bph3 and today I will tell you about my passion and latest research on a hooptie called as BUGATTI VEYRON EB16.4.

Bugatti Veyron The Bugatti Veyron EB 16.4 is a High class engined sports car, designed and developed by the Volkswagen Group and manufactured in , France firstly by Bugatti Automobiles organization. The Super Sport version of the Veyron is now fastest street-legal production car in the world, Its latest version is banned due to top speed of 431 km/h .The original version has a top speed of 408.47 km/h . On 6 April 2013, Bugatti set the record for having the highest top speed of any roadster in the world with the Veyron Grand Sport Vitesse, reaching on average a top speed of 408.84 km/h .

The Veyron's chief designer was Hartmut Warkuss, and the exterior was designed by Jozef Kabaň of Volkswagen, with much of the engineering work under the guidance of engineering chief Wolfgang Schreiber. A number of special variants have been produced. In December 2010, this car was named under genius world record. Origin of the car

In 1998, the Volkswagen Group purchased the trademark Bugatti in order to revive the brand. Starting with the Bugatti EB118, they presented at various international auto shows. In 1999 Tokyo Motor Show, the first study of the Veyron was presented. At the time, the name of the concept car was "Bugatti Veyron EB 18.4,". The decision to start production of the car was taken by the Volkswagen Group in 2001. The first prototype was completed in August 2003. In the development to series production, however, considerable technical problems had to be addressed, so that the start of production was delayed repeatedly, until September 2005.

Name origin The Bugatti Veyron EB 16.4 is named in honour of Pierre Veyron. Bugatti development engineer tested Bugatti with different organization and won the “24 hours of Le Mans” while driving a Bugatti. The "EB" refers to Bugatti founder Ettore Bugatti and the "16.4" refers to the 16 cylinders engine. World record controversy

At the beginning of April 2013, driving.co.uk (also known as Sunday Times Driving) began an investigation following claims from US car maker Hennessey Venom GT got the new world’s fastest car with speed of 427 km/h, taking the crown from the Guinness World Record-holding Bugatti Veyron Super Sport with a recorded speed of 427.6 km/h but the Hennessey was 3.4 km/h (2.1 mph) slower than the Veyron but Hennessey dismissed Bugatti’s official record saying that the Veyron Super Sport was restricted to 415 km/h (258 mph) in production form and that for it to achieve its record top speed of 431.0 km/h (267.8 mph), the car used was in a state of tune not available to customers. Hennessey said its Venom GT, on the other hand, was road-ready and unmodified and was therefore a production car in the strict sense of the term.

There is also contention about whether the Hennessey Venom GT is in fact a "series-production" car as it can only be registered for road use in the US as a (modified) Lotus Exige. Driving.co.uk requested clarification from Guinness World Records, which investigated this claim and found that indeed the modification was against the official guidelines of the record.

Upon finding this, Guinness World Records voided the Super Sport's record and announced it was "reviewing this category with expert external consultants to ensure our records fairly reflect achievements in this field." After further review, SSC, the producers of the Ultimate Aero TT, said that they had reclaimed the record. However Guinness World Records later said they had reinstated the Super Sport's record, after coming to the conclusion that "a change to the speed limiter does not alter the fundamental design of the car or its engine." 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 lbf·ft) of torque.[2][24] 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). Top speed

German inspection officials recorded an average top speed of the original version of 408.47 km/h (253.81 mph)[5] 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 at the time had the highest top speed of any street legal production car. Back in the Top Gear studio, co-presenter Jeremy Clarkson commented that most supercars 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.[25] The car's everyday top speed is listed at 343 km/h (213 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.[21] For top speed mode the driver must, while stationary, 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[21] titanium pistons and the rear calipers have six pistons. Bugatti claims maximum deceleration of 1.3 g 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).[21] 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 a kilometre (third of a mile).[21]
