Until this year's April Fool's Day, the highest top speed achieved by the Nissan GT-R to date was in the 192mph range, though exactly who owned the figure was disputed. Then Hennessey Performance Engineering claimed to have raised the bar and set the new record at 193.7mph (311.7km/h). Along the way, they set an impressive 2.8 second 0-60mph run - without the aid of traction control.

The top-speed figure was set at the Texas Mile using a Hennessey Performance Nissan GT-R GTR700. It's not surprising considering the brutal 700hp (522kW) and 630lb-ft (853Nm) output of the upgraded Godzilla, and it's within 4mph of the car's maximum speed possible on stock gearing, which maxes out at 197mph at redline in top gear.

Getting to that top speed is a brutal experience, pulling 1g in acceleration to get to 60mph in 2.8 seconds, 100mph in 6.7 seconds, and 186mph in 24.79 seconds - well under half of the 53.3 seconds the stock GT-R requires to hit that speed. For a visual illustration of what that is like, check out the video below.
