The Wright StreetDeck is an integral, low floor double deck bus. It uses a modular underframe designed and built by Wright. The front and rear axle modules are derived from the New Bus for London.[1] It uses an offset, longitudinally mounted, 5 litre engine which can be removed together with the transmission, cooling system, and aftertreatment system.
Attention was paid to reducing the weight of the vehicle and increasing its efficiency. One noticeable measure is the reduction in height of the upper deck windows. This uses less glass and reduces solar gain. However, there is an option for flush-mounted glazing in addition to a glazed staircase.
The initial StreetDeck had a front end similar to the Gemini 2, but eliminated the old B-pillar on the driver's side. It used a strip of LEDs for the running lights in the bumper. The rear was restyled with a more rounded appearance and new window arrangement. A new exterior was introduced at the 2014 Euro Bus Expo. The front features more angular lines and rectilinear headlight cluster.
In 2014, Wright introduced their Micro Hybrid Technology. The bus operates like a conventional diesel vehicle, however the energy that is recovered during braking is used to power various electrical accessories such as air compressor, radiator fans, and power steering.
Wright began testing their hybrid-electric technology on the StreetLite and StreetDeck in 2016. The 96 volt hybrid system has two motor/generator units on either side of a Voith transmission. During deceleration, the kinetic energy is converted to electricity and stored in lithium ion batteries. The electricity is used to help accelerate the vehicle. Working in concert with Micro Hybrid Technology, the hybrid-electric system can further reduce emissions and fuel consumption. Production of the StreetDeck HEV commenced in 2018.[2][3]
At the end of November 2016, Wrightbus launched a hydrogen fuel cell variant of the StreetDeck at London’s City Hall. The Ballard fuel cell produces electricity, augmented by batteries, to power the wheels. The vehicle may be charged overnight.[4] Wright officially introduced the StreetDeck FCEV at the 2018 Euro Bus Expo. The bus has a range of 322 kilometres with an extended range of 426 kilometres available.[5] In October 2020, the first StreetDeck FCEVs were delivered to FirstGroup’s operations in Aberdeen, Scotland.
In 2019 Wrightbus unveiled a 10.6 metre long, 4.2 metre tall left-hand-drive version of the StreetDeck in an effort to win an order from Santiago, Chile. The bus had a Euro 6 Mercedes-Benz OM936 engine and was configured as a 96 volt hybrid.
Wright announced their second generation StreetDeck FCEV in February 2021. It is equipped with the Voith Electrical Drive System (VEDS). The StreetDeck FCEV was soon renamed StreetDeck Hydroliner FCEV. It has a range of 280 miles. The battery-electric StreetDeck Electroliner BEV also uses the VEDS. It has a range of 200 miles and a fast charge time of just 2.5 hours.
At the end of 2023, Wrightbus introduced a new look StreetDeck. Designed to meet new Transport for London safety standards, the redesigned StreetDeck improves safety in a collision for pedestrian and cyclist with soft crash front zones, has better visibility with enhanced vision and blind spot warning, as well as other improved passenger safety standards.[6]
