Ideal ratio spread thanks to progressive gear-ratio steps

With eight speeds and a progressive gear-ratio spread (1st-gear ratio 6.57, 8th
gear 0.63), the transmission covers the entire spectrum from precise manoeuvring at inching speed to low and fuel-saving rpm at motorway speed. In contrast to other transmissions in this performance class, the GO 240-8 PowerShift transmission's gear-ratio steps are progressive, ensuring near-perfect power link-up both when upshifting to accelerate and when downshifting on uphill inclines.

Second gear is used as the starting gear on the flat. The transmission ratios have been optimised to suit bus and coach operation, meaning that it is not normally necessary to skip gears. The gear changes themselves are smooth and swift whilst the transmission's control unit responds quickly to changes in topography or load requirements.

Easy to use, with manual mode if required

The automated transmission is extremely easy to use. Usually the driver will opt for automatic mode, although they can intervene manually at any time simply by nudging the shift lever forwards or backwards. In this case, the transmission remains in automatic mode. Pushing the shift lever to the left is all that it takes to engage manual mode, enabling the driver to change gear whenever required by nudging the lever, providing this is technically feasible.

Wide choice of engines and transmissions

The new-generation Travego features the same proven drivetrain components as its predecessor. As before, the OM 457 LA engine with a displacement of 12.0 litres, an output of 315 kW (428 hp) and a peak torque of 2100 Nm now comes as standard. Additionally there is the Mercedes-Benz OM 457 LA 6-cylinder in-line engine with a displacement of 12.0 litres, 335 kW (456 hp) and a torque of 2200 Nm. There is also the option of the OM 502 LA V8 powerplant with a displace­ment of 15.9 litres, an output of 350 kW (476 hp) and a maximum torque 2100 Nm, should extra power be needed. All of the engines are available as a Euro 5 version.

As for the transmission, the Travego comes as standard with a six-speed manual unit in the shape of the GO 210-6 or GO 230-6 with joystick-style gearshift. Special equipment includes the new Mercedes GO 240-8 PowerShift eight-speed automated transmission. Meanwhile, the economical and quiet-running Mercedes‑Benz HO6 hypoid rear axle comes with a choice of ratios, allowing a perfect drivetrain configuration every time.

Chassis: new trailing axle with independent wheel suspension

Major new features have also been incorporated into the chassis for the new-generation Mercedes-Benz Travego. Here too, the Travego sets new standards in terms of comfort and handling dynamics. One of the focal points of the three-axle models is the new trailing axle with independent wheel suspension, whose advan­tages include improved track guidance, smoother suspension characteristics thanks to lower unsprung masses, extra installation space and a design that is around 150-kg lighter due in part to the axle design and electronic control of the still hydraulically actively steered axle.

All variants of the Travego benefit from modified front-axle mountings that are even more effective at preventing thumping noises. What's more, the axle is more smoothly sprung yet loses none of its edge in terms of track guidance or damping properties. And the familiar direct road feel provided by the steering remains intact. Standard equipment for the Travego now also includes electronic level control.

New interior, monitors with 19-inch screen diagonal

The new-generation Mercedes-Benz Travego is more comfortable than ever, not least thanks to large monitors with a 19-inch screen diagonal, which afford passengers an unhindered view of films or television programmes from any seat. In addition to this, the ceiling and the luggage racks have been redesigned to further boost their visual appeal and reduce their weight.

The model year 2009 range

Like its forerunner, the range of new-generation Travego models comprises three high-deck touring coaches: the Travego (two axles, 12.18-metres long), the Travego M (three axles, 13.0-metres long) and the Travego L (three axles,
14.03-metres long).
