Mazda turns the rotary

Ask Mazda global design chief and RX-8 architect Ikuo Maeda if he will ever rule out the rotary, and the answer is always a resounding ‘no’. Adding fuel to reborn-rotary speculation is a recently filed patent application for an inverted, turbocharged Wankel that places the intake port at the bottom and the exhaust port at the top. According to the US application, this more compact top-mounted turbo option, which in 2020 could power a production version of the RX-Vision concept, has the potential to boost performance and allow the engine to be mounted lower.
