Mercedes-Benz Tourismo

The Tourismo is the high-deck touring coach Daimler Buses sells in volume. Daimler Truck says the 40,000th of them left the line at the beginning of 2026; the release attaches that figure to no particular generation. In the same release, more than 26,000 units had been built by the time the third generation’s high-deck coach went on sale in autumn 2017 — the figure marks the point the count had reached immediately before that launch, not a tally the third generation itself produced.

The specification table on this page comes from the facts sheet Mercedes-Benz hosts itself, which covers four models; its footer read 09/2026 when this page was last checked against it, on 22 September 2026. Where a claim comes from a Daimler Truck press release or from the maker’s model page instead, the text says which.

Four models and their differences

The four are the Tourismo at 12,295 mm, the M/2 and the M/3 at 13,115 mm, and the L at 13,935 mm. All four are 2,550 mm wide and 3,680 mm high. With mirrors the lengths become 12,656 mm, 13,476 mm and 14,296 mm.

Mercedes-Benz’s model page describes the base Tourismo as intended for flexible use such as school trips on weekdays and excursions or short trips at weekends, and presents the L as a long-distance coach “for many passengers with a lot of luggage”.

The M/2 and M/3 share a length to the millimetre and differ in axle configuration. The M/2 is a two-axle coach; the M/3 puts a third, actively steered trailing axle under the same body. On the data sheet the two also differ in turning circle, in how the length is divided between wheelbase and overhangs, and in other rows, among them hold, gross vehicle weight, maximum passengers, the width of the second door and the lift.

The M/2’s turning circle is 23,774 mm; the M/3, which is the same length, needs 21,428 mm, and Mercedes-Benz’s model page credits the M/3’s agility to “the superiority of three axles over a length of 13.1 metres”. The sheet also gives the M/3 the shorter wheelbase of the two, and the two-axle base Tourismo, on the same wheelbase, turns in 21,634 mm; the sheet does not say what accounts for the difference. The longest model, the L, turns in 23,327 mm — so the 13,935 mm three-axle coach turns in less space than the 13,115 mm two-axle one.

Front overhang is 2,890 mm on all four. Wheelbase is 6,090 mm on the Tourismo and the M/3 and 6,910 mm on the M/2 and the L, with a further 1,350 mm from drive axle to trailing axle where one is fitted, and a rear overhang of 2,785 mm on the three-axle models against 3,315 mm on the two-axle ones. Added together, those figures give every printed length exactly on all four models; the sum is ours, not the facts sheet’s.

One engine on the data sheet, four power steps

Every engine row the facts sheet fills, in all four columns, names the same block: the Mercedes-Benz OM 470, a 6-cylinder in-line unit of 10.7 litres, declared Euro VI E. What changes from column to column is the power step. The maker’s own model page for these same four models names a second engine, the OM 471, that no row of the facts sheet carries, and calls the L’s engines Euro 7.

The document lists 265, 290, 315 and 335 kW, and torque figures of 1,700, 1,900, 2,100 and 2,200 Nm. The L is the exception: it is offered with three steps rather than four, and 265 kW is not among them. Sub-step E is the one that added cold-start emissions to the on-road evaluation, which is set out in Euro 6 and Euro 7 explained.

The sheet lists three gearboxes, the same three on all four models: the ZF TraXon 2 Coach in its first, unstarred transmission row, and the ZF EcoLife CoachLine and the ZF EcoLife AP in rows the sheet stars, its footnote reading “* Optional equipment”. A fourth transmission row is printed and left empty, and no Mercedes-Benz gearbox appears. The sheet does not say whether the Mercedes-Benz units have been withdrawn. The previous edition, footed 03/2026 and still the one Mercedes-Benz served on 6 September 2026 (Internet Archive capture), listed Mercedes-Benz GO 190-6, GO 210-6, GO 230-6 and GO 250-8 gearboxes alongside a ZF Ecolife AP. Daimler Truck’s release of 16 September 2024 described a Mercedes-Benz six-speed manual and the fully automated Mercedes-Benz PowerShift eight-speed alongside the ZF Ecolife 2 Coachline automatic with torque converter, which it said was available for all Tourismo models with the OM 470 at 315 kW. The model page now names the ZF TraXon 2 Coach and the ZF EcoLife CoachLine.

Aerodynamics are quoted as an air resistance of 0.33 on all four models; Daimler Truck’s release of 19 March 2026 calls the same figure a drag coefficient (cw = 0.33).

Weights and axle loads

The sheet gives a gross vehicle weight of 19,500 kg for the two-axle models and 24,750 kg for the three-axle models. Permitted axle loads are identical across the range — 7,500 kg on the front axle and 12,600 kg on the drive axle — with 5,750 kg on the trailing axle where one exists. The sheet gives one tyre size, 295/80 R 22.5, for all four models.

The sheet gives a 480-litre fuel tank on all four models, split as 260 litres on the left and 220 litres on the right, and a 40-litre AdBlue tank of which 35 litres are usable.

Those axle figures do not add up to the gross vehicle weight. Two axles at their individual maxima come to 20,100 kg against 19,500 kg; three come to 25,850 kg against 24,750 kg. Both sums are ours. Each axle has a ceiling, and the vehicle has a ceiling lower than their sum, which loading every axle to its own maximum would exceed.

The sheet’s 19,500 kg is the same number as the 19.5 tonnes Annex I point 2.3.1 of Directive 96/53/EC allows a two-axle bus. That comparison is ours, and the two are not the same kind of number. Article 1(2) makes the Annex I weights circulation standards, referring to loading conditions rather than production standards, and Article 4(2)(b) lets a Member State authorise national passenger transport that does not meet them; the sheet’s figure is the vehicle’s own gross vehicle weight. The difference between the two kinds of number is read out in how to read a coach data sheet.

Steering, axles and brakes

The chassis table names a ZF 8098 Servocom steering gear, a ZF RL 82 EC front axle and a Mercedes-Benz RO 440 driven axle on all four models. The front axle has independent suspension with an anti-roll bar, and the drive axle has an anti-roll bar of its own; on the M/3 and the L the trailing axle adds active steering with its own independent suspension. Air suspension with electronic level control (ENR) and a raising/lowering system are both standard on all four; kneeling is optional throughout.

The brakes table adds pneumatic disc brakes on all axles to a list the sheet marks standard on all four models: the Electronic Stability Programme (ESP), an electronically controlled braking system (EBS), an anti-locking system (ABS), Brake Assist (BAS), Acceleration Slip Regulation (ASR), and a retarder limiter (RL) alongside the secondary water retarder (SWR). An automatic bus-stop brake with a pull-away lock is optional on all four; the parking brake is standard.

Luggage and seats

Luggage volume is 12.1 m³ on the L and the M/2 and 9.9 m³ on the M/3 and the Tourismo. The two coaches of 13,115 mm carry different volumes: the M/3 has, among other differences, 2.2 m³ less hold than the M/2 — our subtraction — alongside a tighter turning circle and a higher gross vehicle weight.

Standard seating is 1/51 on the Tourismo, 1/55 on both M models and 1/59 on the L, and the sheet gives passenger capacity from 44 to 65 across the range. The L has the most seats and shares the largest hold with the M/2. Of the two coaches of 13,115 mm, the sheet gives the M/3 up to 59 passengers and the M/2 up to 57; the model page’s own FAQ gives the M/2 as “the economical two-axle vehicle for up to 55 passengers”, as the 03/2026 edition of the sheet also did.

The transport-capacity table names four seat types, standard or optional the same way on all four models: the Travel Star Eco (TSE) is standard, and the TSE Softline, the TSE Luxline and the Travel Star Xtra (TSX) are all optional. Two driver’s seats are listed: the air-sprung GRAMMER Linea MSG 90.6 P is standard, and the ISRI 6860, with an integrated pneumatic system and a 3-point seat belt, is optional.

Two doors are fitted throughout, and the sheet’s door-position row reads A. The central aisle floor sits 1,370 mm above the road on all four. A wheelchair space is optional on all four models. The lift is optional on the Tourismo, the M/3 and the L, and marked standard on the M/2 alone, which the sheet does not explain. What separates an optional lift from an accessible vehicle is the subject of bus accessibility.

Both doors swing outward, and the glazing is double-glazed throughout with the Opticool windscreen standard; a heatable windscreen is optional. Of the lighting equipment, low beam, high beam, a front fog lamp, entrance lighting and position lights are all standard on all four models; daytime running lights are halogen as standard, with an LED version optional, and the only headlamp row on the sheet is Bi-Xenon with a cleaning system, offered as an option (there is no standard headlamp row). Cornering light, ambient lighting for the luggage compartment, ambient lighting for reversing and ambient lighting for the lift are all optional.

Heating and air conditioning

The heating and air-conditioning table gives a heater with convectors at the side walls and driver’s-area air conditioning as standard on all four models, with the EvoCool Basic system also standard; EvoCool Comfort and EvoCool ComfortPlus are optional upgrades. Cooling capacity for the passenger compartment is 39 kW on the L, 35 kW on the M/3 and 32 kW on both the M/2 and the Tourismo; the driver’s-area unit is 8 kW on all four. Heating power for the passenger compartment is 39 kW on the L and the M/3 and 36 kW on the M/2 and the Tourismo; heating power at the driver’s seat is 16 kW on the L and the M/3 and 18 kW on the M/2, and the sheet prints no figure for the Tourismo. Refrigerant filling capacity is 7.5 kg on the L and the M/3 and 6.5 kg on the M/2 and the Tourismo.

What the safety table declares

Sideguard Assist 2, Frontguard Assist, Front Collision Guard, Traffic Sign Assist, Lane Assist, Attention Assist 2, tyre pressure monitoring, a reversing camera and an extinguishing system are all marked standard on all four models, alongside disc brakes on all axles; the retarder row names a secondary water retarder (SWR) on all four. Active Brake Assist 6 Plus is marked optional on all four, as are adaptive cruise control, MirrorCam, Active Sideguard Assist 3, Cross Traffic Assist and kneeling. Three of those markings disagree with the maker’s other documents: the model page lists ABA 6 Plus among the Tourismo’s standard safety technology; both the model page and Daimler Truck’s release of 19 March 2026 call kneeling standard; and Daimler Truck’s release of 16 September 2024 said adaptive cruise control was then included as standard. The previous edition of the sheet, footed 03/2026, itself marked ABA 6 Plus standard on all four. This page records the current sheet’s markings and leaves the disagreements standing. The regulatory backdrop to most of that list is in mandatory driver assistance systems.

The facts sheet’s own descriptive pages set out what each named system does. Sideguard Assist 2 supports the driver on both sides in turning situations with possibly restricted visibility, detecting moving obstacles and warning the driver to avoid or reduce the consequences of a collision when turning or changing lanes; Active Sideguard Assist 3 extends this to the front and side areas together, warning of oncoming traffic when turning left and of objects at the side when turning right, with a stepped, brake-applying warning if the driver continues to turn. Front Collision Guard is described as a patented system protecting the driver and passengers in head-on collisions. Frontguard Assist informs the driver of people in the immediate vicinity of the vehicle’s front, up to 15 km/h, moving off or driving slowly. Cross Traffic Assist applies automatic braking for crossing vehicles detected in a 65°-to-115° angle range, over the full speed range. Lane Assist (SPA) warns the driver with a vibration in the seat when the vehicle unintentionally leaves its marked lane. Tyre Pressure Monitoring (TPM) displays each tyre’s current pressure and warns of deviations from the optimum. Active Brake Assist 6 Plus (ABA 6 Plus) is described as automatically initiating emergency braking against a risk of rear-end collision with vehicles ahead or stationary obstacles, and as able to detect moving or stationary pedestrians and cyclists ahead of the vehicle too, with an audible and visual warning and automatic partial or full-stop braking; the sheet’s own description carries no speed figure for the pedestrian-and-cyclist detection. Daimler Truck’s release of 19 March 2026, describing the 2024 “Safety Coach” special edition’s version of ABA 6 Plus rather than the current facts sheet’s own wording, does give one: “up to a speed of 60 km/h, it can also react to pedestrians and cyclists”. The adaptive cruise control, ART, maintains a distance the driver sets to the vehicle ahead. MirrorCam is described as replacing the exterior mirrors with cameras, widening the field of view, improving night visibility and eliminating the blind spot when turning right. Traffic Sign Assist compares the vehicle’s speed with the posted limit using GPS and camera data. The Electronic Stability Programme (ESP) is described as reducing the risk of skidding by braking individual wheels within the vehicle’s physical limits; Acceleration Slip Regulation (ASR) prevents drive-wheel spin through braking intervention and engine-torque regulation; Brake Assist (BAS) detects an unusually sudden application of the brake pedal and adds braking force beyond the pedal position, shortening the stopping distance. The AquaBlade windscreen wipers are described as feeding washer water through the blade itself, for visibility with less driving noise and lower fuel consumption. All of these are the sheet’s own descriptions.

Predictive Powertrain Control (PPC) is listed under the sheet’s “Profitability” heading as optional on all four models, alongside Tyre Pressure Monitoring, which the profitability table repeats as standard.

Daimler Truck’s release of 16 September 2024 announced MirrorCam and LED headlamps in the identical housing as options, and a new multimedia system, the Coach Infotainment Series. The same release says Adaptive Cruise Control, Lane Assist, Tyre Pressure Monitoring and Attention Assist, with an interface for alcohol testers at the driver’s workplace, are now included as standard, and that automatic body lowering at speed, previously optional, is now standard too. On the current facts sheet the only row headed as headlamps offers Bi-Xenon with a cleaning system as an option, and the LED row covers daytime driving lights rather than headlamps.

The sheet also declares body strength in accordance with ECE-R 66.02 as standard on all four. No document cited here states a vehicle class. Under the bus class definitions, Class III covers vehicles constructed exclusively for the carriage of seated passengers, in the group above 22 passengers besides the driver, and UN Regulation No 66 reaches single-deck Class II, Class III and class B vehicles above 16 passengers. What its 02 series requires of a coach in a rollover, and the five ways that may be proved, is in rollover strength.

Source notes

The grid above describes the base 12,295 mm two-axle Tourismo. Three longer models share the same body width, the same height and, on the data sheet, the same engine: the M/2 at 13,115 mm on two axles, the M/3 at 13,115 mm on three, and the L at 13,935 mm on three. The sheet gives a gross vehicle weight of 19,500 kg for the two-axle models and 24,750 kg for the three-axle models. Standard seating is 1/51 on the Tourismo, 1/55 on both M models and 1/59 on the L, with passenger capacity between 44 and 65 across the range. Turning circles are 21,634 mm on the Tourismo, 23,774 mm on the M/2, 21,428 mm on the M/3 and 23,327 mm on the L: the two-axle M/2 needs a wider turning circle than the three-axle M/3 of the same length. The L is offered with three power steps and the other three models with four. All four list the same three ZF gearboxes.
