The MAN TGX EfficientLine 2 actively saves on fuel
More than 4,600 vehicles and packages sold
All the new fuel reduction electronic systems are fitted as standard in the TGX EfficientLine 2. The predictive EfficientCruise cruise control saves up to six per cent in fuel thanks to optimal use of downhill and uphill momentum energy.The driveline of the TGX is suited to particularly low-rev, fuel-efficient driving with the D26 TopTorque engines. Engines with a torque increase of 200 Nm are best paired with really high drive ratios. This additional torque is particularly useful on inclines to facilitate easier driving, with less need to switch to a lower gear and sustainably lower fuel consumption. The new Speed Shifting function shifts more quickly between gears 10, 11 and 12, and reduces interruptions in traction when travelling uphill.
Consistent reduction of air and rolling resistance and engine auxiliary power is in the DNA of the TGX EfficientLine 2: Sun blinds and compressed-air horns are eliminated for this reason; the aerodynamic chassis side skirts help to save on additional fuel. Setting the speed limiter to 85 km/h (53 mph) instead of 89 km/h (55 mph) reduces rolling resistance by ten per cent. Low rolling resistance tyres are also used. In the EfficientLine models, the compressor for the compressed-air supply is controlled as required (Air Pressure Management): The compressor is only activated when compressed air is used. This reduces the operating time by around 90 percent in comparison with a permanently running air compressor for long-haul driving.
The MAN on-board TeleMatics module is also standard in the TGX EfficientLine 2. The truck transmits its fuel consumption and maintenance data to the fleet manager using TeleMatics. The fleet manager is then able to monitor the fuel consumption of the vehicle and driver, and even the tyre pressures and the condition of the brakes for an entire fleet, on their data portal. This makes it possible to ensure that no unnecessary fuel is used. As part of the free MAN ServiceCare service, the MAN service workshop schedules maintenance appointments for its customers on request.
MAN customers can also order EfficientLine packages for other models, e.g. 2- and 3-axle TGS solo vehicles or for the TGS, and receive the core fuel-saving technologies at an attractive package price. EfficientLine packages are also available for the D38 top-of-the-range model.
The following features are combined in the EfficientLine 2 package: EfficientCruise, MAN TipMatic 2, Speed Shifting, Idle Speed Driving, Air Pressure Management, aeropackage, limit of 85 km/h, daytime driving lights, aluminium tanks for fuel and compressed air, and no spare wheel, sunblinds or compressed-air horns as they are no longer necessary.
Forward-looking EfficientCruise GPS cruise control
Huge fuel savings can be made by anticipating and making use of momentum and rolling phases – a challenge that is mastered perfectly by trained and experienced professionals at the wheel. To save the driver having to do this on long and unfamiliar routes, and to support less experienced drivers in driving efficiently, MAN offers a satellite-controlled cruise control system.
The assistant calculates uphill and downhill sections in advance using 3D map data stored on board and the GPS position of the vehicle. It automatically anticipates and controls the speed when driving on inclines and slopes in such a way that the momentum of the vehicle is used to save fuel. A fully loaded 40 ton truck saves up to six per cent in fuel with this system, without losing time on the road.
The assistant controls the speed in precisely the same way as a very well trained driver does, but does so automatically: It builds up momentum in a targeted manner before reaching inclines and carries this momentum into the next incline. The vehicle saves fuel on inclines as its speed is reduced slightly and it is able to reach the top of the incline at the minimum speed limit which has been set. On inclines, EfficientCruise prevents the MAN TipMatic 2 from shifting down if it is clear that the vehicle can reach the top in the current gear. This saves additional fuel.
EfficientCruise can even react further in advance than a trained driver, as the assistant can calculate the route and fuel injection several kilometres in advance during the day and at night.
With a desired speed and one of four possible speed tolerances both selected by the driver, EfficientCruise calculates the appropriate speed for the most fuel-efficient uphill and downhill driving. The driver can adjust the tolerance level for deviations from the set speed at any time to suit the driving scenario. Four field-tested levels clearly simplify the process of choosing the suitable setting for the driver. This is line with MAN’s approach to provide the driver with useful default settings, enabling them to achieve optimum levels of consumption whilst avoiding driving errors.
EfficientRoll: Fuel reduction by coasting at idling speed
The MAN TGS and TGX trucks with TipMatic 2 also come with the EfficientRoll gearbox function. It saves fuel by making use of slight downhill gradients when coasting and is especially designed for slightly downhill stretches of motorways or highways.
The gearbox then automatically shifts into neutral and allows the vehicle to coast without the engine braking effect reducing the vehicle speed. This enables the vehicle to carry the momentum from gentle downhill sections into a following flat stretch or slight incline. If the truck accelerates beyond the prescribed or permitted speed while coasting, the MAN TipMatic 2 automatically re-engages the gear.
MAN Solutions at the transport logistic trade fair
The interlinked services from MAN Solutions offer solutions to help businesses to be particularly competitive in the transport industry. All solutions help to decrease the total cost of ownership (TCO) by making maintenance costs transparent and predictable, unlocking savings potential in fleet management and as a result of driver training, and helping to plan workshop visits in a time-effective manner.
MAN TeleMatics – maximising efficiency
The MAN TeleMatics system is the basic tool for these interlinked services. The new, more powerful hardware, a new maintenance data portal and a new app expand the possibilities of MAN TeleMatics.
The more powerful hardware module transmits more technical data from the truck and transmits positioning data more quickly. Fleet managers and driver trainers can therefore assess the technical condition of trucks, plan maintenance and train drivers in efficient driving in a more targeted manner. Customers can also select the ideal service package for their needs from four new, simply structured options. The basic rate includes the ‘maintenance data’ and ‘daily vehicle usage analysis’ as basic functions. The eco, time and map additional options allow businesses to optimise economic driving operations, transmit driving times and use geo functions. The MAN TeleMatics hardware is built into most TGX and TGS long-haul vehicles as standard. The system is also a fixed constituent part of the TGX EfficientLine and the new TGX EfficientLine 2.
The practical MAN TeleMatics Fleetmanagement app – which has already been presented with the RedDot Award for its especially good information design – is available free of charge for iPad and iPhone and Android devices.
At the transport logistic trade fair, MAN TeleMatics will be previewing another app tailored to the needs of the driver: the DriverConnect app assists the driver with their core daily tasks and makes highly effective communication between the driver and fleet manager possible, for instance for order management.
The new maintenance data portal clearly presents the multitude of transferable data on maintenance scheduling. MAN TeleMatics, for example, allows braking conditions to be controlled individually for each wheel. The tyre pressure of all wheels, including the trailer, is also transmitted and can be centrally reviewed by the fleet manager. Monitoring brakes and tyres is both an important safety aspect and an important factor in vehicle fuel consumption. MAN TeleMatics therefore makes it possible to optimise the TCO of vehicles in a targeted manner. The fill level of the diesel and AdBlue tanks and the engine oil level can also be monitored by the technical manager. Moreover, information on trailers can be accessed from the MAN TeleMatics portal, such as cooling temperatures and data from the cooling unit.
MAN ServiceCare
Proactive maintenance scheduling is a particularly efficient way to reduce costs. The new ServiceCare service package provides the MAN service outlet commissioned by the customer with access to maintenance data pertaining to customer vehicles, meaning it can then control maintenance management. The workshop arranges maintenance appointments in direct consultation with the customer’s schedule and organises the work to be carried out in such a way that the workshop visit is as short as possible. This also includes ordering planned spare parts. The vehicle is thus back in action and earning money more quickly. The service is free of charge for customers.
Proactive maintenance scheduling also decreases repair and administrative costs: No important repair or maintenance work is forgotten – avoiding unnecessary follow-up costs.
MAN therefore makes proactive maintenance easily accessible, as MAN ServiceCare can be used independently of a service contract. Customers with TeleMatics vehicles that would like to use the service simply need to allow their MAN service outlet to access the maintenance data portal. Even the basic service package from MAN TeleMatics covers all information required by the workshop for maintenance scheduling.
Connected CoDriver
Connected CoDriver from MAN ProfiDrive is a distance training course lasting from one week to three months. During the course, drivers are assisted by an instructor who acts as a virtual co-driver. The coach is highly involved with the driver, the vehicle and the route. The aim is for the driver to develop a particularly economical style of driving on the road. The technical tool that helps here is MAN TeleMatics, which offers the trainer insight into the driver’s style of driving.
The live-training Connected CoDriver achieves success very quickly and is completely practical, as support is provided on a daily basis. Coaching by telephone allows queries to be clarified easily and directly. Using driving data, trainers provide tips on economical driving, such as on using continuous braking systems or the manual switch, or on anticipatory coasting.
Support for three months costs around EUR three per day. The result affects TCO costs in the long term: in several hundred test drives to measure the consumption, drivers consumed an average of 2.3 litres less for every 100 kilometres once they had undertaken efficiency training. Covering a total distance of 150,000 kilometres on long-distance journeys creates a potential saving of around 3,500 litres of diesel each year.
