Groupe Gruau

The Bluebus was developed by the Gruau Microbus company in Saint-Berthevin in western France. Le Groupe Gruau has become known in France as a company for its decades of activity in the body shop , which is still Gruau 's domain . The company was founded in 1889 as a car repair shop in Laval / western France. The body shop was added in the early 1930s and over time became the mainstay of the company.

Today Gruau sees itself as an internationally active specialist in the conversion of vehicles, employing over 1000 people worldwide.

Model development

Internal combustion engine

The body design or the design of the Gruau Microbus has been around since 2002. It arose from a project called "Bus de futur" (in German: "Bus of the future"), which was launched in 2000, and was accompanied by market studies went. From the start of production in 2004 to the beginning of 2008, around 150 buses were built, which are equipped with internal combustion engine drives. The vehicles were intended for around 30 municipalities in France and Burgstädt near Mittweida in Saxony. An electrically powered microbus was tested back in 2005.

Battery bus

The revised model was equipped with an electric drive and lithium polymer batteries from the French manufacturer batScap , a subsidiary of Bolloré . The batteries are three traction battery packs of lithium metal polymer batteries with a charging capacity of 30 kWh each, i.e. 90 kWh per vehicle. They require an operating temperature of 60 ° C to 80 ° C, whereby the vehicle can be operated at outside temperatures of −20 ° C to +60 ° C.

The first deliveries of the electric version of the bus, which was presented in 2008 as “Microbus Electricity”, took place in 2011 under the protected label “Bluebus”. Manufacturing was relocated from Saint-Berthevin (near Laval) to Bolloré in Brittany in 2016.

In 2015, BlueSolutions, a company belonging to Bolloré, presented a 12-meter-long bus that has been in service at the RATP since Paris , with more than 20 units in 2019. Since 2018, it has also been in service in Rennes and Brussels .
