If you are going 218 MPH in the United States on a public road, you would have you thrown right in jail in just a second. But, on some parts of the German Autobahn, the only thing that limits the speed is the car you are driving. Here we have a video of a high speed run on the German Autobahn, where the main participants are a Koenigsegg Agera R and a Porsche 918 Spyder. Here you can see that the speedometer of the Porsche is reaching up to 350 km/h or 217.48 MPH, as it tries to catch the Swedish hypercar. The Porsche 918 Spyder produces 887 HP and 944 lb-ft of torque. The top speed of the car, according to Porsche, is 214 MPH and it can run from 0 to 60 MPH in just 2.5 seconds. The Koenigsegg Agera R produces 1,140 HP and 885 lb-ft of torque. The theoretical top speed of the car is 273 MPH and it can run from 0 to 60 in 2.8 seconds. Check out the video.
Note: Attempting to reach speeds this high is a dangerous endeavor, and do not attempt to recreate anything seen in the video above. Be safe, and be smart. Source:Youtube
