The 9ff GT9R is most likely the fastest Porsche GT3 at the moment. But while the tuner only offered details on the coupe versions, rumors say the German tuner is also taking orders for a speedster version of the GT9R.
We expect for the cabrio version to use the same 4.0-litre flat six, mid-mounted engine that thanks to massive twin-turbo is able to produce 1120bhp and a peak torque of 774 lb ft. The coupe version was named by its producer ’the world’s fastest street-legal car: it sprints from 0 to 60 mph in 2,8 seconds and can hit a top speed of 257mph are on tap.
This rendered appeared on the 9ff United Arab Emirates (UAE) official page and comes with the message: "Fastest Car in the World - 257 MPH - Now available as Coupe OR Convertible."
