/ The first Optare Spectra double-decker, soon to go into service with Reading Buses, is expected to be fitted with a new low-emission Daf engine (CM 18-24 July 1991).
The 9.0-litre 200kW (268hp) charge-cooled engine meets the EC 9NOx emission standard.
It may also be used in Leyland Daf trucks. The Allusuissebodied Spectra already has several features in common with the Leyland Daf 95 Series, including its instrument panel.
Daf and Optare deny that a low-emission, 9.0-litre engine even exists, and insist the Spectra is being fitted with a traditional 8.25-litre model.
But London Central, which has ordered 22 Spectras, has told CM that the Spectra is indeed being fitted with a new engine "which is not very big with loads of power".
