Chassis Z-1040: Length of 10.4 meters, designed for routes with a high passenger demand, being the longest model in this generation, ideal for busy routes in metropolitan areas. Engines The first generation of the Ayco Zafiro was equipped with a variety of diesel engines designed to offer good performance and durability in urban operating conditions: International DT-466E: A 7.6-liter inline six-cylinder engine, famous for its reliability and high torque, suitable for the Z-930 and Z-1040 chassis configuration. This engine offers a power of between 195 and 250 hp, depending on the calibration, and stands out for its fuel economy and ease of maintenance.
Mercedes-Benz OM-366: A six-cylinder inline engine with a displacement of 6.0 liters. This engine delivers a power of up to 177 hp, being ideal for the most compact versions of the Zafiro, such as the Z-840 and Z-930. Its compact and fuel-efficient design made it popular in this first generation.
Mercedes-Benz OM-904: 4.25-litre inline four-cylinder engine, providing 170 hp and a good balance between power and consumption. This engine was an option in smaller configurations (Z-840), especially suitable for lower load routes.
Mercedes-Benz OM-906: A 6.37-litre inline six-cylinder engine with power of up to 211 hp. This engine was ideal for longer chassis configurations such as the Z-1040, where greater power was needed for high-demand routes.
General Characteristics The first generation of the Ayco Zafiro offers a simple and functional construction, with a straight-line design that allows for easy maintenance. Its internal structure was adapted to different numbers of seats, optimising passenger space and maximising efficiency.
The versatility in engine and chassis made this generation suitable for various urban operating conditions, providing reliable and economical transport.

The first generation of the Ayco Zafiro Sport (known as the facelift of the 2007-2009 Zafiro G1) introduced an aesthetic and functional redesign that sought to modernize the appearance and improve the aerodynamics of the model. This facelift included several visible changes and mechanical options that offered greater efficiency and performance.
Aesthetic and Structural Changes Hood: The hood was redesigned with more aerodynamic lines and smooth curves, improving aesthetics and allowing a reduction in air resistance. This also facilitated access to the engine compartment for maintenance, a benefit especially useful in urban operations.
Headlights: New headlights with a more angular and modern design were incorporated, providing better illumination and increasing nighttime visibility. The headlights also improved passive safety, by integrating position lights and better light dispersion in low visibility conditions.
Rear Wall: The rear wall was redesigned to give the bus a more contemporary look. This change included new taillights and a more efficient arrangement of components in the rear area, improving both aesthetics and functionality.
Rear Bumper: The rear bumper was updated with a more enveloping shape, made of impact-resistant materials and designed to reduce damage in minor collisions, thereby reducing maintenance costs.
Engine Options In this version of the Zafiro Sport, the 4700 SCD chassis offered new MaxxForce engine options from the MWM family, designed to meet Euro IV emissions standards, suitable for urban environments where greater efficiency and lower emissions were required: MaxxForce. MWM 4.8: An inline four-cylinder diesel engine with a displacement of 4.8 liters. This engine produces a power of around 180 HP at 2200 RPM, with a torque of 680 lb-ft. Its compact size and low fuel consumption made it ideal for short-distance urban routes and more compact chassis.
MaxxForce MWM 7.2: This 7.2-liter, inline six-cylinder engine delivers 225 HP at 2200 RPM and 850 lb-ft of torque. Ideal for longer chassis configurations on the Zafiro Sport, it would support higher passenger loads on high-demand routes while maintaining a good balance between power and fuel efficiency.
General Features The first generation of the Ayco Zafiro Sport with facelift represented a significant evolution compared to the original model. Design changes offered a more modern and aerodynamic look, while MaxxForce MWM engine options provided improvements in performance and environmental efficiency.
