Euro 6 Merc heavy-haulers break cover

Mercedes-Benz has unveiled it’s updated Actros- SLT tractor unit – the first heavy-duty tractor on the market that meets Euro 6 emissions standards – along with a new Arocs-SLT variant.

Developed and produced by Molsheim-based Custom Tailored Trucks (CTT), though overseen by Merc’s factory in Wörth, the SLT takes over the mantle of top-of-the-range heavy hauler from the Euro 5 Titan model, which will still be manufactured for non-European and overseas markets in Euro 3-5 varieties.

Merc is offering the SLT with the latest version of its 16-speed PowerShift 3 automated transmission, programmed with a special Heavy mode designed to pull loads of up to 250 tonnes.

A turbo retarder clutch is also fitted as standard which greatly reduces wear when pulling away, and functions an effective brake.

The new SLT features Merc’s OM 473 Euro 6 in-line sixcylinder engine, rated at 625 bhp (460 kW) and providing 3000 Nm of torque at 1100 rpm.

The Actros-SLT comes with air suspension and can be specified with either GigaSpace or BigSpace cabs, while the Arocs-SLT is fitted with steel suspension and can be ordered with BigSpace (2.5 m) or StreamSpace (2.3 m) cab as required.

Mercedes-Benz said both the Actros and Arocs SLT models are available to order immediately, with Actros delivery commencing in December. All-wheel drive variants of the Arocs-SLT will start arriving from April next year.
