Polyphony Digital has released more details about the X1, which is its idea of a race car that’s freed of all regulations. It all started with Polyphony Digital getting in contact with the Red Bull F1 team, and challenging aerodynamicist Adrian Newey to build the ultimate racer. Polyphony Digital has revealed that the X1 generates downforce in a very active manner. Similar to the Chaparral 2J Can-Am and Brabham BT46B F1 "fan cars," the X1 actively draws air out from under the body, developing a partial vacuum and helping the car adhere to the road surface. Add wild spoilers and wings and the car is able to pull a maximum lateral acceleration of 8.25 g.
At the same time, Newey's team worked to reduce aerodynamic drag as much it can, which would help push the X1's top speed into the stratosphere. Consequently, the front and rear wheels are fully enclosed with aerodynamic fairings and its cockpit is enclosed underneath an elongated canopy. Red Bull and Polyphony Digital deny reports that the X1 design uses a gas turbine powerplant.
Rather, the car is powered by a direct-injection, twin-turbocharged 3.0-liter V-6, which can deliver 1483hp at 15,000 rpm and 527 pound-feet of torque at 12,000 rpm. So far, there has yet to be a statement indicating what gearbox that engine is mated to.Regarding its performances, Polyphony Digital says the Red Bull X1 is able to sprint from 0 to 60 mph in just 1.4 seconds (96 km/h), to 100 mph (160 km/h) in 2.8 seconds and to 200 mph (320 km/h) in 6.1 seconds. Now words about the top speed, but do expect to exceed 350 mph. [via AutomobileMag]
