The one-piece composite side wall, cantilever furniture, rounded forms and the choice of mostly smooth materials mean that the new generation of Citeas is better and easier to keep clean. Sand, dust and other dirt accumulate less easily. In this age of COVID-19, hygiene is, more than ever, an essential part of design. A number of interior parts in the Citea, such as the vertical and horizontal grab rails and the passenger seats, can be provided with an antibacterial coating. Special filters, in combination with good monitoring, ensure optimal air quality in the bus.
DESIGN OF THE LIGHT
Green light when the doors open and it’s safe to get out. Red light that flashes when the door closes and the new Citea departs. Indirect lighting under the seats so that passengers can reach the seats and luggage racks safely even when it’s dark at night. Light has a great influence on the travel experience and is therefore an essential part of the design philosophy. By using colours and intensities, the lighting can be easily adjusted to the situation and atmosphere. If, for example, an unsafe situation arises, the driver can adjust the lighting so that it has a de-escalating effect.
AERODYNAMICS: LESS NOISE
The VDL design philosophy makes the journey even more pleasant for both driver and passengers. Because the side wall is made of one piece, there are no gaps or holes. Due to the high-tech aerodynamic design, the wind causes less turbulence. Furthermore, the curves at the front, various spoilers and the sharp angles at the rear have led to a significant reduction in air resistance. The traveller will experience more comfort and less noise in the new generation of Citeas. The improved aerodynamics of the vehicle were intensively tested in the wind tunnel, with simulations and on the road.
ATTRACTIVE AND MODERN DESIGN
In the new generation of Citeas, we transport our passengers to school, work or to see their friends. Every day we get tens of thousands of people moving. Our interior philosophy is based on the principles of a modern public waiting room, where the audience is made up of people with different destinations, cultures and backgrounds. We attach great importance to accessibility, hygiene, safety, vandalism resistance and attractive design. For VDL Bus & Coach, speaking an attractive design language is an important asset in getting more people to opt for public transport.
Testing in climate regions
In order to achieve a higher range, battery capacity testing is essential. VDL Bus & Coach subjected the new generation of Citeas to extensive tests in different climate regions. Not only in winter conditions but also at high temperatures in Southern Europe. In winter, energy consumption is reduced by an average of 30%. Throughout the year, customers can count on an average of 20-25% less energy consumption and 20% more action radius.
Range of up to 600 kilometres
The range of the new generation of Citeas has been considerably improved: all vehicles cover a distance of 500 to 600 kilometres. Even in bad weather conditions (-15 degrees Celsius), the Citeas can still drive 250 kilometres 100% electrically. VDL Bus & Coach responds to the standards required in urban and regional transport today: in metropolitan areas, the Citeas can handle 24-hour operation, while on regional lines, which are increasingly being electrified, distances of up to 70 kilometres are no longer an exception.
Trend: electric regional transport
With the new generation of Citeas, VDL Bus & Coach is responding to a clear trend: more and more regionally operating transport companies prefer electric transport. This is an unstoppable development. Regional transport requires both range and passenger capacity, while passenger comfort must remain optimal at all times. The Citeas offer a large radius of action, even in adverse weather conditions.
4 length variants, 5 types
The new Citea product range consists of four length variants and five types: LF-122 and LE-122, LE-135, LE-149 and LF-181. All types are extremely suitable for both city and regional transport, with the exception of the 18.1-metre low floor, which comes into its own as a city bus. The 13.5-metre variant is an efficient vehicle on 2 axles that can compete with a 3-axle vehicle in terms of seating capacity. Not having the third axle means a lower purchase price, minimal repair and maintenance costs and more favourable energy consumption.
A novelty in the new generation of Citeas is the composite sidewall, which is constructed in one piece and developed by VDL Bus & Coach itself. This causes less vibration and filters the noise coming from outside. In addition, it leads to less energy consumption. The innovative composite sidewall construction is 15% lighter than a conventional sidewall. Furthermore, the introduction of this composite sidewall has greatly improved the insulation of the bus, which in turn has significantly reduced the consumption of the climate system. There are no longer any cold bridges in the sidewall either. The result is more comfort for travellers.
Batteries in the floor
The standard battery package of the new generation of Citeas is integrated into the floor. The absence of batteries in the passenger compartment ensures optimum passenger flow and maximises the number of seats. By placing the batteries in the floor, the centre of gravity of the bus is lower, making roadholding more stable. Driver comfort has also been significantly improved.
110 passengers in 12.2 metres
One of the most important principles in the development of the new generation of Citeas is about increasing the minimum number of passengers. An efficient vehicle layout, low unladen weight, optimum weight distribution and the length of the bus are the results. The accessibility of the bus has improved. At the same time, more people can ride along: up to a maximum of 110 people in a 12.2-metre vehicle. Each type of Citea from VDL Bus & Coach has room for at least 45 seated passengers.
The new generation of Citeas is based entirely on an electric powertrain. When developing this kind of e-vehicle, you are no longer tied to the fixed locations of components that you previously had to take into account, such as the position of the combustion engine. As a result, VDL Bus & Coach has been able to determine the technical design entirely on its own and to distribute the weight of the components as optimally as possible by, for example, laying the batteries in the floor, integrating the motors into the wheels and positioning the axles and doors in the most favourable location.
