Mercedes-Benz Atego
The Mercedes-Benz Atego is a range of general-purpose rigid trucks introduced by Daimler Truck in 1998. A new model was introduced in 2004, followed by a facelift in 2010 and another new model in 2013. The latest version is available in gross vehicle weights of 6.5 to 16 tonnes (t) and is powered by a straight 4- or 6-cylinder engine.
The first generation Atego debuted in 1998. It was intended as a successor to the LK model range. At the time of its launch, the Atego offered a total of 25 different basic types and 240 model variants. Around 170,000 units were produced until 2004.
The truck won the International Truck of the Year award in 1999 which would later be supplemented with another win by the second generation Atego in 2011.
In 2000, a new 240 kW (326 hp) top-of-the-range version of the heavy Atego chassis was brought onto the market. In 2001, the new Axor model series emerged from the heavy-duty Atego weight class with gross vehicle weights of 18 to 40 tonnes. The Axor combined the heavy chassis of the Actros with the long Atego cab.
The second generation Atego debuted in 2004 at the International Commercial Vehicle Show. The front section was redesigned, with new H7 clear-glass headlamps, high-set white-glass indicators, wind deflectors and new exterior mirrors. The interior of the four different cab variants was also completely redesigned, with the cockpit more grouped around the driver and a new climate control system which was more similar to the heavy-duty Actros models. A new nine-speed transmission replaced the previous twelve-speed transmission. The new Telligent automated gearshift was also introduced as an optional extra up to 175 kW (238 hp) along with a roll-back lock built into the Telligent brake system. Soon after launch, the Atego was linked to the Fleetboard telematics system.
In 2005, a 12-ton payload-optimised model was introduced, which had a low chassis, 17.5-inch tyres and a new 160 kW (218 hp) four-cylinder engine. Also in the same year, Atego models over 18 tonnes were renamed Mercedes-Benz Axor. In 2006, dump truck versions of the Atego were fitted with high-performance disc brake technology on all axles. The 250,000th Atego was delivered in June 2008. From March 2010 the entire Mercedes-Benz Atego series was made available with EEV (Enhanced Environmentally Friendly Vehicle) compliant engine versions.
The second generation Atego was initially available with three basic engine variants. The 4,250 cc inline-four OM 904 LA with 130 kW (177 hp) power, 675 N⋅m (498 lb⋅ft) torque, 17.75 to 1 compression ratio, and Unit-Pump System (UPS) technology single-nozzle fuel-injection pumps. The 6,374 cc inline-six OM 906 LA with 170 kW (231 hp) power and 810 N⋅m (597 lb⋅ft) torque or 205 kW (279 hp) power and 1,100 N⋅m (811 lb⋅ft) torque. Both variants with Unit-Pump System technology with single-plunger fuel-injection pumps and centrally arranged 6-hole injection nozzles.
There were five different gearboxes available for the Atego. Firstly, the G56, G60 and G85 all-synchromesh manual gearboxes with six forward gears and one reverse gear. They were available with engine-mounted linkage gearshift (G56 and G60), hydraulic gearshift (G85) or Telligent automated gearshift. The G131-9 was a direct-drive gearbox with eight synchronised forward gears, one constant-mesh crawler gear and one reverse gear. It consisted of a 4-speed basic gearbox with pneumatic rear-mounted range unit. Gears were shifted hydropneumatically. Last but not least was the Allison 3000P electronically controlled automatic gearbox. It featured five forward gears and one reverse gear. The chassis was available in wheelbase lengths between 3,260 mm and 5,360 mm at standard spacing of 300 mm. The frame rails featured a continuous hole spacing of 50 mm. Frame components were made of cold-formed E 380 TM and E 500 TM high-strength steel. It consisted of a two-piece modular frame with two symmetrical Z-profile members on front end and straight, untapered, U-shaped longitudinal flange at the rear which were interconnected by means of riveted gusset plates. The front suspension had parabolic leaf springs and for the rear there was a choice of leaf springs or air-suspension with Telligent level control. Steering was power assisted, recirculating ball with variable steering gear ratio.
