It's all up to Maesima now to continue further development... unless they also abandon their plans, writing off millions of dollars in the process.
This actually reminds me of how the new, mid-engined Alpine A110, originally meant to be twinned with a similarly-powered Caterham, ended up as an all-Renault program. Abandoning the ZXE and RXE altogether, however, is total cowardice in my view, especially when Saminda-Auxuras will never build an engine with >4 cylinders ever again. Yes, these sports car programs may have been too expensive to develop, and continuing to increase the efficiency of its current range is all well and good, but this leaves a huge gap in their lineup between the mainstream cars and C5000R - one that will ultimately be impossible to fill.
In fact, this shift away from performance and towards economy reminds me of the last line of evo magazine's last-ever review of the Honda S2000 while it was still on sale, way back in 2009; it ended in "...abandonment of the car enthusiast". That's the predicament Saminda-Auxuras is facing right now... and it's causing potential customers to seek other brands' cars instead. No doubt quite a few engineers at Harris-Albury will be relieved at this latest announcement.
