BMW has lifted the veil of secrecy on a wild V12-powered version of the first-generation Z3.
The experimental prototype, created by BMW’s research and development division, was built as an engineering exercise with the aim, in the words of one BMW source, “to see how far we could stretch the concept”.
No firm details on the one-off Z3 have been forthcoming, although it is thought to run BMW’s M73 engine. Used in the earlier 750i and 850Ci, the big V12 boasted a capacity of 5.4 litres and kicked out 321bhp and 361lb ft of torque.
By comparison, the most powerful first-generation Z3 model, the Z3 M Roadster, used the 3.2-litre straight six from the M3 with 321bhp and 261lb ft.
