No diesel for current BMW Z4
Project leader Ingo Lasslop told What Car?: 'I can't see it – especially after the launch of the new [petrol] sDrive18i model.'
BMW had been expected to offer a rival to the Audi TT Roadster 2.0 TDI and Mercedes SLK 250 CDI, with the 181bhp 2.0-litre diesel engine from the 320d a likely power source.
However, it's believed that fitting BMW's current-generation four-cylinder diesel engine in the Z4 might not be as straightforward as originally thought.
Furthermore, the Z4 already weighs around 150kg more than an equivalent Audi TT Roadster, and a diesel engine would add around a further 30kg.
