Different players in the motor industries have developed various criteria in defining what production cars or vehicles are. These definitions range from those given by the Guinness Book of Records to those of Motorsports. Agreeably, they revolve around the number of units of the same brand made; the legality when it comes to the vehicle usage in the intended market; and the fact that they are primarily constructed for retail sale to consumers.
In a bid to ensure that their consumers are going fast enough while on the road, manufacturer are keen on outdoing each other when it comes to producing fast moving production cars. Even though Bugatti Veyron was the first ever production car to reach 400 km/h, other brands have since topped this record. Our sieved list of top 5 fastest production cars in the world is pegged on the measured top speed and not theoretical speeds.
1. Koenigsegg Agera RS
Koenigsegg Agera RS, a car from a Swedish car manufacturer, tops the list as the fastest production car ever manufactured. The Guinness Book of world record featured Koenigsegg Agera RS in the lead when it did a maximum speed of 444.6 km/h. This was done upon the closure of the public highway between Pahrump and Las Vegas’ 11-mile section. Prior to making the record official, they conducted two runs in both directions of the section. Koenigsegg achieved a top speed of 456 km/h on the first run. On the return journey, however, the vehicle was struggling with strong head wind and an uphill gradient, resulting into it achieving a speed of 436 km/h. The car that set this record had a 5-liter twin-turbo v8 engine with 1,360 HP. Koenigsegg wasn’t at all pleased by being outdone by Bugatti Chiron at 400 km/h and a subsequent challenge by Bugatti Veyron at 434.5 km/h in 2010. In the Koenigsegg Agera RS case, the manufacturer used a single set of Michelin cup 2 tires. of 345/30-20 behind, and 265/35-19 front.
2. Hennessey Venom GT
Hennessey Venom GT comes second in our top 5 list of the fastest production cars. This car which was developed by the US engineers, made a clean record of 435 km/h as its highest recorded speed. Prior to being challenged by Koenigsegg Agera RS, Hennessey Venom GT managed to set the new world record as the fastest production car during the Florida-based Kennedy Space Center run. It managed to beat the record 431 km/h that was prior set by Bugatti Veyron Super Sport. The test driver, Brian Smith, started the car from rest and finally came to a halt on a 5.1-kilometer tarmac stretch, having broken the record. The car is powered by a 7-liter, twin-turbo v8 engine producing 1.244 HP. It is predicted that the car could do much better if the test track could be conducted on a longer NASA runway.
At the third position comes Bugatti Veyron Super Sport. Upon being taken to the track on the Volkswagen’s Ehra-Lessian grounds, Bugatti Veyron Super Sport managed to do a maximum speed of 431 km/h. Henry Raphanel, official test pilot of Bugatti, took the entire company’s engineering team by surprise when he recorded this unbelievable speed. Some of the factors that enabled the car to register such a high speed were the 1,106 pounds of torque and the increment of the engine output from 1,001 to 1,200 horse power. The unit is mated to a twin-clutch gearbox which is seven-speed. Moreover, the car also enjoys the benefits of a redesigned chassis, a newly developed aerodynamic kit, and a body structure which is all-carbon fiber. The car has a total of 10 radiators notably: 1 engine oil radiator; 1 differential oil radiator; 1 radiator for the air conditioning system; 1 transmission oil radiator; 3 engine radiators; and 3 heat exchangers for the air-to-liquid intercoolers. To protect the tires of the car, the five subsequent production models were electrically limited to 257.9 miles per hour.
Bugatti Chiron was a further developed car from Bugatti Veyron. It retained the same massive engine of 16.4 liters, W16, capable of producing 1,479 HP. Even though the design was updated by Bugatti to a new supercar, there is still much commonness with the Veyron production brand. In a stunning 2.4 seconds, Bugatti Chiron accelerates from zero to 100 km/h. For safety reasons, the company is said to have limited Chiron’s speed to 420 km/h. Were it not for this reason, it is speculated that Chiron could record as high as 463 km/h. At one point in time, the car had risen to the top of the list of the world’s fastest vehicle to complete the 0-400 km/h test which it did within 32.6 seconds. This car, manufactured by Buugatti Automobiles S.A.S, a France-based motor company, succeeded the Bugatti Veyron and was first on March 1, 2016 at the Geneva Motor Show. It was named after Louis Chiron, the Monegasque driver. Its engine as well, produces 1,600 N.m of torque and 1,103 kW at 6,700 rpm.
5. SSC Ultimate Aero
At the end of our list of top 5 fastest production cars in the world features the SSC Ultimate Aero car. It is a mid-engined sports Car which was produced by the SSC North America. In the period starting 2007 to April, 2010, SCC Ultimate Aero held the fastest production car title with an ability to do 413 km/h as its top speed. This car was, however, not sold with electric driver aids such as traction control or antilock brakes. The SSC Ultimate Aero 2009 new version had a 15% increased power over the previous version. The car as well has an increased 20% air flow to the engine that prevents the engine from overheating. It also features a new AeroBrake system, a spoiler that rises to 203.2 mm upon the pressing of the brakes. Its engine produces horsepower of 1,287 bhp and a torque of 1,112 lb.ft. In proving its capability to attain the theoretical speed projected at 439 km/h, SSC Ultimate Aero was put on a road test where it made two runs in opposite directions on the same road. On the first run, the car recorded a top speed of 414. 26 km/h and on the return journey, it did 410.16 km/h. The results for these runs were later verified on October 9, 2007 by the Guinness World Records.
At the moment, the aforementioned cars top the world list of the five fastest production cars in the world. However, considering the stiff competition offered by various players in the motor industry, these records could soon be toppled. Until that time, Koenigsegg Agera RS will remain at the helm as the fastest production car ever manufactured and tested.
