Every year, production car manufacturers compete to have a crazy fast top speed for their car. Even though the cars will not reach its maximum potential in the public road, the “fastest production car” title is still considered a critical selling point for a supercar.
To measure the top speed, Guinness World Records required the cars to have a two-way opposite run on an independent road. The average of the maximum speeds in both runs then is taken as the car’s top speed. Thus, cars like Bugatti Chiron Super Sport 300+ (304 mph) and Hennessey Venom GT (270 mph) are excluded from the list since they didn’t fulfil the requirements. With that said, here are the top 3 fastest production cars in the world.
3. SSC Ultimate Aero – 256.14 mph
The SSC North America manufactured less than 20 Ultimate Aero in 2007. In the same year, Guinness World Records crowned the vehicle the fastest production car until the production of Bugatti Veyron 16.4 Super Sport in 2010. The two-way opposite run was taken at West Richland, Washington State with each scored the speed of 257,41 mph and 254.8 mph resulted in 256.14 mph on average.
The car is powered by a twin-turbocharged V8 engine that produces 1,183 bhp with 1,483 Nm torque. The car’s nose and spoiler are modified to increase the aerodynamics of the car. These specifications allow the car to accelerate from 0 to 62 mph in only 2.8 seconds.
2. Bugatti Veyron 16.4 Super Sport – 268 mph
Initially, the French supercar manufacturer only produced 30 limited Veyron. The cars are equipped with a speed limiter of 258 mph to keep the wheels intact. With the limiter removed, the car amazingly reached the average speed of 268 mph in 2010. Guinness World Records verified Bugatti’s two-way run at Volkswagen’s Ehra-Lessien circuit which each marked 268 mph and 269 mph and makes them one of the fastest production cars in the world.
This vehicle is powered by 16-cylinder 8.0 litre W16 engine with four turbos. It is also equipped with an automatic gearbox with 7-speed twin-clutch. The engine produces the maximum power of 1200 bhp with 1500 Nm torque that enables the car to accelerates from 0 to 62 mph only in 2.5 seconds.
1. Koenigsegg Agera RS – 278 mph
In November 2017, this Swedish supercar put its name down in the Guinness World Records list as the fastest production car in the world. The record was accomplished in 110 miles closed public road between Las Vegas and Pahrump. The beast did two-way run and astonishingly reach the average speed of 278 mph. This hypercar also successfully hit 284 mph top speed on one way. Even more shocking, there is no special modification in this vehicle to break the record. Instead, Koenigsegg used their customer’s Agera RS for the run.
To reach such speed, every Agera RS exploits 5.0 litre V8 twin-turbo engine which can generate up to 1,380bph and 1,000 lb-ft of torque. The advanced technology from the One:1 program is also installed on the car to optimise aerodynamics to increase the downforce. Combined, the power makes it possible for the car to accelerates to 60 mph in under 2.9 seconds and 124 mph in only under 7 seconds. The incredible acceleration can be achieved even with a power-limiting rear-wheel part.
