Watch out Audi – BMW is  gunning for the R8! Auto Express has uncovered incredible plans for a  sensational two-seater roadster, set to be badged Z9. Replacing the Z8,  which went out of production back in 2003, it will be BMW’s flagship  supercar, sitting at the very top of the range, giving the brand some  extra glamour and a rival to the R8 and Mercedes SLS.
Its  taken some time for the newcomer to come to fruition, first appearing at  the 2005 Los Angeles Motor Show as the California Spyder concept. A  sleek, low-slung drop-top with carbon-fibre bodywork to save weight and a  700bhp BMW F1 engine, which revved to 17,000rpm.
The firm’s  top brass gave the green light for production, albeit with conventional  powerplants. But the economic downturn caused the California Spyder to  be put on ice in 2007, and since then BMW has withdrawn from Formula  One, too. But with an improving financial climate, the car is back on  the cards.
As you can see from our exclusive illustrations  (inspired by the sketches of the California Spyder and the stunning  Vision EfficientDynamics concept from the 2009 Frankfurt  Motor Show), it’s no surprise that bosses want the roadster to  happen.
The proportions are classic roadster: just like the  smaller Z4, the driver is pushed right back to near the rear wheels,  while there’s a long bonnet and tiny front and rear overhangs to give  the car a real sporting character. At the back, the double-bubble deck  is a retro touch similar to that on Porsche’s Boxster Spyder.
The  car will feature some of the ‘layered surfacing’ design themes  introduced by new styling boss, Adrian Van Hooydonk. Plus the active  front splitter and rear diffuser will change shape at speed to optimise  air flow around the car to improve fuel efficiency.
Key to the  resurrection of the roadster project is BMW’s upcoming electric urban  car. The machine will be made from carbon-fibre reinforced plastic  (CFRP) to save weight, developed by Seattle-based SGL Automotive Carbon  Fibers. The material will be used throughout the Z9 too, making it light  and very strong.The flagship roadster will use BMW’s large car platform  from the 5, 6 and 7-Series. Both aluminium and magnesium will be used  in the subframes and suspension to save weight, while the passenger  cell, which sits on top of the chassis, will be made from CFRP. Parts of  the bodywork, including the folding hardtop, will also be made from the  material.
A very minimalistic design will feature inside, as  in the Z8. But instead of being retro-inspired, the dash will be cutting  edge, with slimmed-down air vents and touchscreen controls.
Power  will no doubt come from the new 4.4-litre twin-turbo that will power  the next M5. Developing 600bhp, the engine would be mated to a highly  efficient twin-clutch gearbox, providing power to the rear wheels  through a torque vectoring M limited slip differential.
Brake-energy  regeneration and stop-start would be standard.
An electric version could appear, too, rivalling the Audi e-tron and electric Merc SLS. A production car would not arrive before 2014. But when it does, the R8 and SLS will have a fight on their hands. For more details click here.
