Highly doubt it as Wrightbus and ADL have all together stopped making Euro 5 models and as each bus takes around 2 months on average to build means they stopped building them around October with the last ones being registered this month.
Optare however have been continuing to Build Euro 5 Solos till now so giving there are still Euro 5 Mercedes engines in the uk, Theres a chance the solos could be Euro 5 if they start building the GNE Solos in January, Ready for there projected March entry into service.
