Production time frames for the introduction of the new Acura NSX have been vague, but rumors had been circulating earlier this year that a production-based test mule might was expected to make an appearance at Goodwood last month, but those speculations never became a reality. This week, spy photographers at Nurburgring caught a glimpse of an NSX prototype lapping the 'Ring in what appeared to be near-production form, reigniting hopes that the hybrid supercar might soon break cover. Unfortunately, events seen today at the track seem to indicate that the NSX might not be quite ready for primetime just yet.
