Wasn't it to do with overheating due to the radiator pack being on the nearside so they'd get blocked from sucking up leaves etc
That was certainly a problem with the Scania K320UB / E300s, not heard about it affecting the MANs.Wasn't it to do with overheating due to the radiator pack being on the nearside so they'd get blocked from sucking up leaves etc
It's not even a certain engine model. MAN engines in general have been plagued by issues. The main one that springs to mind is the EGR Valve issues with Euro5 engines, particularly the D26 unit used in trucks and coaches such as the MAN TGX and Neoplan Tourliner. It got to the point where MAN were offering new engines and parts free of charge. Despite the issue first surfacing 8 years ago there has still been reports of the same problem with Euro 6 vehicles.MAN had an issue with a certain Engine model which initially they refused to accept liability for which was partly to blame for their falling out of favour and hence why the ones retained are Cummins engined.

Overheating and overall fragility of MAN engines was indeed a problem with those, in much the way they were some years previously on the Optare VectaIt's not even a certain engine model.

Any thoughts on whether this is some sort of 'UK import' issue ? - surely, it's the same kit being used, in good volumes, in Europe (or perhaps not)?Overheating and overall fragility of MAN engines was indeed a problem with those, in much the way they were some years previously on the Optare Vecta
My understanding is the nearside (UK) position of the radiator was definitely an issue. Even if the engine doesn't overheat, the lack of air circulation means it's working harder than it should be and it degrades engine life. You also have other issues to consider - such as having a UK body plonked on top of it and how that can impact ventilation.Any thoughts on whether this is some sort of 'UK import' issue ? - surely, it's the same kit being used, in good volumes, in Europe (or perhaps not)?

I believe I may be right in saying that the only integral MAN products offered here are Neoplan coaches and airport buses.Going on a slight tangent here, but have any integral MAN vehicles been offered over here? Perhaps this would solve some of the issues.
I thought their first EV was Street AirThe StreetDeck Electroliner – the first ever EV from Wrightbus – is the perfect combination of range and efficiency, maximising power and offering class-leading recharge times.
I think it is Forsee power that supplies the batteriesUtilising a French battery pack which delivers 454kw and a 200-mile range, the Electroliner will recharge in two hours 45minutes and cope with all routes, whether urban or rural.
Nor has the bus compromised on layout or capacity, with batteries efficiently stored around the bus to ensure passenger capacity comfort is not compromised.

The StreetDeck Electroliner – the first ever EV from Wrightbus – is the perfect combination of range and efficiency, maximising power and offering class-leading recharge times.
Utilising a French battery pack which delivers 454kw and a 200-mile range, the Electroliner will recharge in two hours 45minutes and cope with all routes, whether urban or rural.
Nor has the bus compromised on layout or capacity, with batteries efficiently stored around the bus to ensure passenger capacity comfort is not compromised.
Founded in 1946, Wrightbus has been at the forefront of public transport for 75 years and is still based in the heart of Ballymena, Northern Ireland.
Rescued from administration by green entrepreneur Jo Bamford in October 2019, the company is going from strength to strength, also launching a world-first hydrogen bus as well as an advanced telematics system to give real-time updates on performance, maintenance and CO2 savings.
CEO Buta Atwal, who last week took the wraps off a fleet of 20 hydrogen buses alongside London Mayor Sadiq Khan, said Wrightbus continued to deliver on its net zero promise.
The Wrightbus hydrogen-fueled bus is already in operation in Aberdeen, London, Belfast and Dublin, and there is growing interest for all its zero emissions offerings from around the globe.“We have gained a strong reputation for our hydrogen double deck but we want to lead the world in zero-emissions full stop,” he explained.
“Wrightbus has the best brains in the business when it comes to technology and our StreetDeck Electroliner puts us squarely at the front of the pack.
“We haven’t weighed the bus down with a high battery volume just so we can say it’s got the most power or range; instead, we want to be the most efficient vehicle on the road so we’ve combined optimum power with a class-leading rapid charge meaning our electric bus spends more time on the road than any other.”
The Ballymena-based company is in discussions with operators from the USA, Australia, South America and the Far East as authorities race to hit net zero targets.

Notes to editors:
Wrightbus, based in Ballymena, Northern Ireland, builds the world’s lightest bus chassis and has developed the world’s first double-decker hydrogen bus. Owned by Jo Bamford, who bought the business in 2019, Wrightbus is at the vanguard of the zero-emission bus movement. The first hydrogen buses are in operation in Aberdeen and London, with more local authorities looking to introduce them to their fleet over the coming years.
Presumably it means to say First EV Double Decker.I thought their first EV was Street Air
Indeed it is as confirmed by this article from last November:I think it is Forsee power that supplies the batteries
Wrightbus signs up Forsee Power for electric bus batteries04 November 2020
Wrightbus has signed a new contract with French battery supplier Forsee Power, which has supplied the Northern Ireland-based manufacturer since 2013.
The Bamford Group, new owner of the Wrightbus bus brand, has renewed its long-term partnership with Forsee Power with a contract for several hundred battery systems per year. The equipment of the city of Belfast from 2021 will be a first key project.
Forsee Power will supply Wrightbus with its new generation of slim batteries, whose extra-flat format allows an easy integration into the chassis of vehicles (standard or double-decker buses).
First, Forsee Power will equip the buses with the new ZEN-Slim high-energy batteries (11 kWh, 16 kWh & 22 kWh). The flat format allows an easy integration into the floor or other vehicle spaces. These modular battery systems have an integrated liquid cooling system and will be intended for 100% electric buses with high autonomy and overnight charging. Each bus will be equipped with 333 kWh to 423 kWh.
Then, the new generation of FLEX-Slim batteries will complete the technical offer and will be integrated into hydrogen buses (standard or double-decker) and 100% electric buses.
In 2016, the two pioneer partners broadened their cooperation in the field of hydrogen buses, for which Forsee Power has developed the high-power Pulse technology. This partnership won the JIVE (Joint Initiative for Hydrogen Vehicles Across Europe) call for tenders, and to register nearly 100 orders for hydrogen buses in major cities such as Aberdeen, London, or Liverpool. The Streedeck H2 Buses thus reach a range of 320 km.
The first hydrogen-fuelled double deck bus on Earth to go into production, the StreetDeck Hydroliner is already in operation in Aberdeen, London, Belfast and Dublin – with interest from around the globe.
Wrightbus is in discussions with operators from the USA, Australia, South America and the Far East as authorities race to hit net zero targets.
The figures make for incredible reading – in the first three months of this year alone, Wrightbus’ iconic fleet in Aberdeen saved 170 tonnes of CO2 from entering the atmosphere.
Add in clean-air filtration systems and a refuel time of just eight minutes and it’s clear what hydrogen is exciting operators.
Founded in 1946, Wrightbus has been at the forefront of public transport for 75 years and is still based in the heart of Ballymena, Northern Ireland.
Rescued from administration by green entrepreneur Jo Bamford in October 2019, the company is going from strength to strength, also launching a class-leading electric bus as well as an advanced telematics system to give real-time updates on performance, maintenance and CO2 savings.
CEO Buta Atwal, who last week took the wraps off a fleet of 20 hydrogen buses alongside London Mayor Sadiq Khan, said Wrightbus continued to deliver on its net zero promise.
Enhancing the Union’s reputation as pioneers of hydrogen adoption and production, Wrightbus has a core team of developers and designers at its factory in Ballymena.“We have already witnessed the astonishing impact our hydrogen buses have had on the streets of Aberdeen, saving more than 170 tonnes of CO2 in the first three months of operation alone, and now we’re on the streets of London to help clean up the toxic city fumes too,” Mr Atwal explained.
“Sadiq Khan was clear in his mission to turn London’s iconic red buses green and, by partnering with Wrightbus, the most important city in the world is able to clean up its act.
“I am hugely proud of the strides we have made in the last two years but this is no time to stand still and say ‘we’ve done it’. Pioneering this technology means we have to lead from the front.
“We are constantly developing and evolving our platforms to squeeze every last ounce of efficiency out of the system and give customers old and new that legendary Wrightbus service. Just as importantly, we are creating vital UK jobs using buses designed and made in the UK. It is a huge plus for us.”
“We have some incredible talent here at Wrightbus right across the board, from design through to production, which means we are perfectly placed to continue leading the way in zero emissions’ technology,” Mr Atwal concluded.
“Wrightbus is growing and we are always looking for the best new talent on the market to come and join us.”
For comparison the BYD/E400 offering produces 382KWHs with a 160 mile range, so the statistics for the Streetdeck are pretty impressive in comparison with it's 200 mile rage.I am amazed at the reference on the link to 454 Kw power
In old money that is 608 horsepower, which is about 4 times the power of a diesel Streetdeck. A sort of Streetdeck GTI turbo

Presumably they're brushing that one under the carpet since it was such a failure.I thought their first EV was Street Air
I guess they can claim the "Shaggy" defence - as a pre-Bamford era product "it wasn't me"Presumably they're brushing that one under the carpet since it was such a failure.
So a Wright StreetLite DF is now a Wright StreetLite Ultroliner DF? Bit weird, Hawk is a strange name tooWrightbus have updated their website with a revised product line up, the new single decker is called the GB Hawk. - https://www.wrightbus.com
Full product line up:
Streetlite Ultroliner
GB Hawk
Streetdeck Ultroliner (Diesel)
Streetdeck Electroliner (Battery Electric)
Streetdeck Hydroliner (Fuel Cell Electric)
The website also confirms that the Hawk and Streetdeck are offered with both the OM934 and OM936 engines.
Correct, the "Ultroliner" name is used for diesel variants of the StreetLite and StreetDeck.So a Wright StreetLite DF is now a Wright StreetLite Ultroliner DF? Bit weird, Hawk is a strange name too
I quite like the Hawk name, the "GB" part is presumably because it's built to "UK & Ireland" specification which would make sense as Wrightbus were/are intending to offer it to markets outside the UK once the Hydrogen and Battery Electric variants come along in September.The names are dreadful.
The new support products, WB Support 365, WB Uptime 365 are not much better.

They're offering the diesel Streetdeck with the 6cylinder OM936 engine now which is far superior and better suited than the OM934Browsed it and laughed at some of the stuff on there - some pretty terrible quality low resolution photos of it's products (the DF Streetlite for example) and bold statements for the StreetDeck Ultroliner EU6 like "Meet the UK's Favourite Bus".... Might want to avoid selling that one to Lothian, First Leeds or Arriva...

I was going to bring that up.

Quite possibly during the last year where Diamond Bus in Bolton ordered a large fleet of Streetdecks (90+ vehicles, I think?) whilst the only sizeable recent order for the E400 has come from Stagecoach Manchester (52 vehicles)I was going to bring that up. Has the diesel Streetdeck ever outsold the diesel Enviro 400?
Hawk is an awful name. What does GB stand for…? ‘Great Britain’ would be an odd choice for a manufacturer based in Northern Ireland?
It's because it's built to UK specification, long term Wright intend to offer the Hawk outside the UK.Not first time Hawk has been used as a name for buses, used to be a BMC Hawk about 15 years ago, some might still be around
Humber cars used name Hawk for many years too
I do wonder if GB Hawk is some sort of temporary joke name, we are watching (hawks have exceptional eyesight), or using the political usage (Hawk is someone favouring war), and GB is probably aimed at Government (Give us Bribe) yet another research and development subsidy from tax revenues in London and SE
