The rumor mill is back in action as a new report is indicating the jointly-developed BMW Toyota sports car will become the new Supra and Z4.

We've already heard these rumors in the past, Nikkei is reporting the cars could arrive as early as 2017. Unfortunately, the report is light on details so we're taking everything with a grain of salt.

Putting that massive disclaimer aside, previous rumors have suggested the suggested the jointly-developed sports car will have a front-engine, rear-wheel drive layout with a 50:50 front to rear weight distribution. It could also feature carbon fiber and aluminum components to help reduce weight.

Engine options remain a mystery but there have been countless rumors suggesting everything from a 2.0-liter four-cylinder with 218 PS (160 kW) to a twin-turbo 3.0-liter six-cylinder with approximately 400 PS (294 kW).
