The majority of StreetDecks produced have been the standard diesel variant, fitted with a Daimler OM934 5.1 litre, 4-cylinder Euro 6 diesel engine competing mainly with the Volvo B5TL and Alexander Dennis Enviro400 MMC. The first five prototype demonstrators to be produced were fitted with a front end similar in appearance to the outgoing Wright Eclipse Gemini 2 double-decker, before Wrightbus' new standard Stealth front end styling was fitted to production examples. The first prototype StreetDeck entered service with Arriva Derby, built to Sapphire specification for route 38, in November 2014. This was followed by further examples with First South Yorkshire, First Greater Manchester, Arriva London and Go North East in January 2015 and London Central in February 2015. The first order for StreetDecks was made by Brighton & Hove for 24 that entered service on the Coaster service between Brighton and Eastbourne in March and April 2015; as of June 2018, Brighton & Hove have taken delivery of 82 examples. FirstGroup have been the largest customer for the StreetDeck, taking delivery of 194 examples as of June 2018. Twenty-two entered service on First South Yorkshire's new flagship X1 Steel Link service in September 2016, having entered service on route X78 from Sheffield to Doncaster in November 2015 due to delays in the opening of the Bus Rapid Transit North. Go-Ahead Group have been the second largest customer, with the Oxford Bus Company taking delivery of 41 StreetDecks between 2015 and 2017 for its city 3, city 5, city 8&9 and Oxford park & ride services. Go North East purchased 26 StreetDecks for its Castles Express X21 and the Angel 21 services between 2016 and 2018. In June 2019, Go North East announced a further order of 31 StreetDecks for its new X-Lines network of express routes. The buses are expected to enter service from Spring 2020. The order includes the first StreetDeck in the UK to feature Daimler's 6-Cylinder engine, originally thought to be the first in the world, but that title went to a StreetDeck in Hong Kong. The first production examples for a Transport for London contractor entered service with Arriva London in July 2016 on route 340.
StreetDeck Micro Hybrid
The StreetDeck is also available with the same Wrightbus Micro Hybrid technology as was first provided in the StreetLite single-decker. The Micro Hybrid package consists of a flywheel and regenerative braking in the bus, which provides electricity used to power the interior lights and compressed air systems, saving up to 10% in fuel costs compared to the standard diesel StreetDeck.
StreetDeck Hybrid
The hybrid-electric variant of the StreetDeck was launched in 2018 alongside the Wright StreetLite Max Hybrid, with the first examples of each entering service with First South Yorkshire at the Olive Grove Depot in May 2018. Later that month, eight StreetDeck Hybrids also entered service on First West Yorkshire's Elland Road park & ride service in Leeds. Oxford Bus Company took delivery of 6 Streetdeck Hybrids for Brookesbus services U1 and U5.
Exports
In 2018 a demonstrator equipped with Daimler OM936LA 295hp engine was exported to Hong Kong and placed in service with Kowloon Motor Bus in 2019. However, the demonstrator was sent back to UK in February 2020. Five entered service in Monterrey, Mexico. Although Mexico drives on the right, they were built as right-hand drive vehicles operating on a busway with left-hand boarding. A 63 seat demonstrator will also operate in Santiago, Chile.
