A version of the 20B known as the "R20B RENESIS 3 Rotor Engine" was built by Racing Beat in the US for the Furai concept car which was released on 27 December 2007. The engine was tuned to run powerfully on 100% ethanol (E100) fuel, produced in partnership with BP. During a "Top Gear" photo shoot in 2008, a fire in the engine bay combined with a delay to inform the fire crews, the car was engulfed and the entire car destroyed. This information was withheld until made public in 2013.
