Tentatively dubbed Z10, the most ultimate of driving machines from BMW would, according to the latest churns of the rumormill, take advantage of lightweight materials – including carbon fiber, aluminum and magnesium – to keep weight down, while offering more space inside than a Porsche 911. The jury's still out on what engine would find itself placed in the middle of the taut chassis, with the company's award-winning V10 reportedly axed in favor of a twin-turbo six (in either V or inline configuration) delivering somewhere in the vicinity of 450 horsepower and 350 lb-ft of torque through an eight-speed dual clutch gearbox.
