ThrustSSC :- The fastest Illegal Car on Earth





 
                                                    Speed 763.035 mph

Thrust SSC (SuperSonic Car) is a British jet-propelled car developed by Richard NobleGlynne BowsherRon Ayers and Jeremy Bliss.





ThrustSSC.
ThrustSSC holds the World Land Speed Record, set on October 15, 1997, when it achieved a speed of 1,228 km/h (763 mph) and became the first car to officially break the sound barrier (not considering the earlier, unsubstantiated claim of the Budweiser Rocket).
The car was driven by Royal Air Force fighter pilot Squadron Leader Andy Green in the Black Rock Desert in NevadaUnited States. It was powered by twoafterburning Rolls-Royce Spey turbofan engines, as used in British F-4 Phantom II jet fighters. It is 16.5 m (54 ft) long, 3.7 m (12 ft) wide and weighs 10.5 tons (10.7 t). The twin engines developed a thrust of 223 kN (50,000 lbf), a power output of 110000 bhp (82MW)[2] and burned around 18 litres per second (4Imperial gallons/s or 4.8 US gallons/s). Transformed into the usual terms for car mileages based on its maximum speed, the fuel consumption was about 5,500 l/100 km or 0.04 mpg U.S.
The record run in October 1997 was preceded by extensive test runs of the vehicle in Autumn 1996 and Spring 1997 in the Al-Jafr desert (located in Ma'an Governorate) in Jordan, a location unknown before for its capabilities as a test range for high speed land vehicles, with numerous advantages compared to the salt deserts of the Western United States.
After the record was set, the World Motor Sport Council released the following message:
The World Motor Sport Council homologated the new world land speed records set by the team ThrustSSC of Richard Noble, driver Andy Green, on 15 October 1997 at Black Rock Desert, Nevada (USA). This is the first time in history that a land vehicle has exceeded the speed of sound. The new records are as follows:
  • Flying mile           1227.986 km/h (763.035 mph)
  • Flying kilometre   1223.657 km/h (760.343 mph)
In setting the record, the sound barrier was broken in both the north and south runs.
Paris, 11 November 1997.

SSC Ultimate Aero :- The Fastest Legal Car on Earth


                                                                      Speed 256.18 mph

The SSC Ultimate Aero is an American-built mid-engine supercar by Shelby SuperCars. Its higher-performance limited production version, the SSC Ultimate Aero TT, is the second fastest production car in the world (behind the 2010 Bugatti Veyron Super Sport), with a recorded speed of 412.28 km/h (256.18 mph). This speed was achieved during tests on September 13, 2007 in West Richland, WashingtonUnited States and verified by Guinness World Records on October 9, 2007. The SSC Ultimate Aero does not have electronic aids like ABS brakes or traction control.
The Aero and the Shelby SuperCars company are the brainchildren of Jerod Shelby (no relation to retired racing driver and sportscar builder Carroll Shelby), who started out building exotic "replicars" including a Fiero-based Ferrari F355 replica and a Lamborghini Diablo replica based on a spaceframe which later was used in the Ultimate Aero prototype. Jerod later moved from building replicas to designing his first Supercar and after seven years it finally began to take shape. Although the basic Aero model is no longer produced, the Ultimate Aero is still in production with an MSRP of around $650,000.
