GREATER GRUNT | Truck Review – Scania 13-litre

Scania’s 13-litre fills the need

There are an amazing number of ways to describe increased horsepower or additional torque, but none seems to get the message home better than the simple expression of ‘more grunt”.

Since the European truck makers started bringing Euro6 engines with their beneficial low emission ratings into the Australian market the powertrain ratings have been increasing.

It’s not only the power or torque output rating that sees higher figures on the spec’ chart. It’s the noticeable change in the feel of the truck on the road, given the realisation that an increase in power and torque means less gear changing, the improved ability of the engine to hold onto a specific gear without downshifting, and ultimately a slightly lower fuel bill.

Like all good things, there’s a benefit in having the bragging rights and Scania in particular is well aware that you can’t sell a secret. Having introduced the highly successful NTG range of new models over the past couple of years, it seems the engineers at Scania are continuing to refine their products and are certainly not resting on their laurels.

The latest upgrade for Scania is reserved for buyers of the 13-litre, six-cylinder Euro6 engine who can now choose the new DC 166 540 hp engine.

The revised engine adds 40 hp over the previous top-of-the-range six-cylinder, but crucially torque increases by 150 Nm to 2700 Nm at 1000-1300 rpm, giving it a 100 Nm advantage over its nearest rival. The 540 hp engine joins the existing 370 hp, 410 hp, 450 hp and 500 hp engines in the Scania 13-litre range.

As the top-rated engine in the 13-litre range, the DC13 166 produces 540 hp (397 kW) at 1800 rpm with peak torque of 2700 Nm rated between 1000 rpm and 1300 rpm.  Fuel injection is by the Scania XPI system with a 21:1 compression ratio and the exhaust brake is capable of generating 242 kW at 2400 rpm.

The Euro6 emissions rating is achieved by using selective catalytic reduction (SCR) and AdBlue. All Scania’s Euro5 and Euro6 diesel engines can run on a mixture of up to 100 percent hydrotreated vegetable oil (HVO) and any proportion of diesel and HVO, regardless of the engine family, helping to substantially reduce CO2 emissions.

Scania has long offered the best torque in each horsepower segment, and the new 540 hp engine continues our push to standardise Euro6 in all segments,” said Dean Dal Santo, Truck Sales Director for Scania Australia.

“The new 540 hp engine will give operators hauling B-doubles an excellent alternative to a higher displacement engine, and with our low rev, high torque technology, they will be able to run as efficiently as possible,” he said.

“The lower tare weight of the 13-litre engine also provides Scania with the ability to reach customers with payload-critical applications,” added Dean.

The six-cylinder, SCR only 540 hp engine has undergone a technical update with improved combustion and gas exchange, lower internal friction, updated turbos and smarter auxiliary systems that only power up when needed, reducing parasitic power loss and consequently benefitting fuel economy.

Under the right conditions the company claims that fuel savings of 2 percent are possible. There are also some benefits to component durability and longevity with the new fixed-geometry turbocharger spinning on ball bearings rather than journal bearings.

“Our in-line six-cylinder range is industry leading when it comes to fuel performance, with 13-litre engines having been crowned ‘Green Truck’ for three consecutive years in Germany,” said Alexander Vlaskamp, Senior Vice President, Head of Scania Trucks.

“The Scania 540 hp engine is aimed at operators that are looking for extra power for overnight express runs where the focus is on fuel economy and where average speeds and legal restrictions on front axle loads keep them from choosing a V8,” Mr. Vlaskamp said.

“In 2018 when we launched NTG 13-litre range with the 500 hp Euro6 engine it immediately attracted a high level of demand both in G-series and also in R-series cab profiles,” said Dean del Santo.

“Combined with our unbeatable five-year/500,000 km scheduled maintenance-included offer, the highest output Scania 13-litre makes even more business sense.”

The new 540 hp engine is available for order now for delivery from June 2020. It can be ordered with the G, R or S-series cabs in the Scania New Truck Generation range.
