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. 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. The hybrid-electric variant of the StreetDeck was launched in 2018 alongside the Wright StreetLite Max Hybrid, with the first examples of each (including 13 StreetDeck Hybrids) 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. 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.
