(autoinsidernews) вЂ" When first caught by spy photographers, most weren't sure if this new BMW roadster was the next-generation Z4 or the all-new Z9. These new photos throw more weight behind this prototype being BMW's new Z9.
While the next Z4 is expected to grow from the current model вЂ" to make room for a smaller Z2 roadster вЂ" this model appears significantly larger than what is expected out of the next Z4.
The spiritual successor to the Z8, the BMW Z9 roadster will be priced above both the 6-Series convertible and the Z8. The Z9's primary competitor is Mercedes' SL-Class roadster, reports Trend.
The prototype's softtop is a fake, and actually is hiding a folding metal hardtop beneath it canvas. The Z9 is expected to feature both six- and eight-cylinder, a range-topping Z9 M could be powered by the M5/6's 500-hp V10, or an even more powerful V12.
