Designed for urban and interurban services, the Sb3 maintains a coordinated image with the rest of our vehicles, with the common aesthetics that characterizes and distinguishes them in the market.
It is focused on short and medium distance routes and has a great modularity and versatility in its interiors. It is available in high floor or Low Entry in its rigid versions on two and three axles, as well as articulated.
Consistency of design
| The Sb3 shares with the other Sunsundegui models a common aesthetic, a powerful coherent brand and product image. Its wide front window with Optikool treatment as standard and its optical groups, interchangeable with those of the Sc5, favor this unified image of elegant lines. Its standard bi-halogen headlights with five-point LED daytime running lights share the same design as the LED taillights. At the rear, the tailgate maintains that special geometry that not only greatly favors the ventilation of the engine but also provides an unmistakable image of Sunsundegui vehicles. The standard power doors are double at the rear and single at the front, which integrates the opening system. The Sb3 has asymmetrical mirrors that are very comfortable for the driver as he can look at them through the side window as if it were a utility vehicle, a side window that is electrically operated as standard. In addition, the design of these mirrors favors great maneuverability, a very important aspect, since this is a bus that carries out a large part of its activity in urban areas. In the design of its interior, spaciousness and luminosity have been given priority, and the “tree” of handrail bars for the support of standing passengers creates an attractive and harmonious image. The dashboard, renewed as in the Sc5, has been given a new look, with a sleek, flowing lines thanks to its avant-garde design, and given its function, the Sb3 has three locations for electronic signs: on the front, on the side and on the rear window. |  |
Road safety
| It is very important for Sunsundegui to equip its vehicles with the latest safety technology. In this regard, in addition to complying with anti-tip regulations (Regulation 66.02), its front structure is reinforced to absorb impacts and thus provide greater protection to the driver and passengers. Both the front end and the front bumper are prepared for the installation of driving assistance systems such as automatic braking and lane change (DSS). The exterior mirrors have an anti-collision system that, in the event of a moderate impact, causes the mirror to fold inward and outward; they provide maximum visibility, comply with current school regulations and are heated. The Sb3 has a 4.3-inch multiplexing screen for maintenance and diagnostics of vehicle operation, as well as a 7-inch TFT screen for displaying cameras (standard infrared reversing, running board, etc.). |  |
Easy maintenance
| For cost-effectiveness, the Sb3 has convenient access for maintenance of the front and rear lights, as well as the tailgate. The modular design is oriented towards easy maintenance of electrical installations, heating, air conditioning and chassis. The front and rear polyester elbows are removable and independent and can be changed quickly and easily. The electrical control units (both chassis and body) have been unified in a single location and are easily accessible. In the Low Entry version, the control unit is located behind the driver’s seat. The multiplexed architecture includes climate control and connection to the chassis; a fault diagnosis system is standard on all vehicles and is displayed on a dedicated screen on the dashboard. |  |
Efficient driving
| The Sb3 is designed with ergonomic criteria in mind to ensure that the driver can work in a comfortable and relaxed manner. For this purpose, it has a large elevated driving position that improves control of the environment. It can be enclosed by a rear partition and a side door and can also be fitted with anti-vandalism locks. The strategic location of the rearview mirrors avoids forced postures and the vehicle has a one-piece motorized blind on the windshield with a view through it and an opaque strip at the beginning to avoid glare. The driver also has a comfortable and ergonomic seat as well as easy access to all vehicle controls and anti-fogging as standard with the possibility of adding a cooling function. |  |
Passenger comfort
| The Sb3 is designed to promote a pleasant ride for the user. It has a wide access to the interior of the vehicle and its solid structure ensures a quiet ride. Individual air and light outlets can be mounted and luggage racks can be fitted in a modular way. The vehicle is equipped as standard with radio, USB socket for audio and video playback, hands-free, digital amplifier and integrated multifunction display. Its spacious interior incorporates transverse lighting in the center of the ceiling by means of LED lights and comfortable seats for seated passengers. |  |
Tailor-made
| As it could not be otherwise, the Sb3 also admits numerous modifications in terms of installations (audio, video, monitors, SAE, CCTV, USB ports on the passenger restraint bars, etc.) and in terms of the distribution of both seated and standing seats, positioning and location of the elevating platform, different arrangement of the safety bars according to the distribution of the passenger, handrails on the luggage rack, etc. |  |
