The Z9 is powered by the world's first V-8 turbo diesel, the 3.9 liter engine first produced for the BMW 7 Series 740d model. The 3.9 liter V-8 is a common rail, direct injection unit. It produces more torque than any other engine in BMW's history, an incredible 413 lbs/ft (560 Nm) of torque. Torque is maintained constantly between 1750 and 2500 rpm to give outstanding performance even at the low end of the rev range. Maximum power is an impressive 245 hp.
The interior of the Z9 is a showcase
of ground-breaking technology and ergonomic design.
The concept of operating the Z9, which BMW calls Intuitive Interaction Concept, allows the driver to easily activate functions while driving without the need to constantly examine and manipulate conventional controls.
The Z9 has only a starter button and light switch on the dashboard. An electronic key is used to activate the driver's controls. Then, a simple starter button starts the engine. The instrument panel folds out when prompted. Classic, circular dials provide feedback to the driver.
A large, 8.8-inch monitor in the center of the dashboard displays all the information the driver needs, apart from the speedometer and tachometer, which are conventional analog instruments. The monitor is positioned within the driver's field of vision, allowing it to be viewed while focusing attention on the road ahead.
Drive or reverse gears can be engaged with a dash mounted lever. The Steptronic transmission can also be operated with steering wheel mounted buttons. These buttons can be used for manually shifting gears.
One of the most striking features of the Z9 is the gull wing door. But, these doors can also be opened like a conventional hinged door!
How is this possible? The conventional doors are actually fitted into the gull wings, allowing the doors to function in both ways. The full-length gull wing doors can be opened automatically at the press of a button on the electronic key. Depressing the button on the remote control will both open and close a door. In fact, holding the button down will cause the door to repeat the procedure indefinitely; in effect, like flapping it's wing!
