In January 2025, NOM-044 for diesel engine emissions for heavy-duty vehicles was implemented after several postponements. Therefore, only vehicles that comply with Euro 6 engines can be produced and imported.
Although the measure is mandatory from 2025, Scania introduced the Euro 6 engine range in 2021 , in anticipation of the possible update of NOM-044, which is why it has been eyeing this market for some time.
“Today, we have the right product strategy for the introduction of the Euro 6 range, both to serve the corporate customer segment and the retail market that requires it, although we know that it is a market that faces more challenges due to the availability of clean fuel,” Jorge Navarro Inostroza, Commercial Director of Scania Mexico, described in an interview with T21.

Based on what Navarro Inostroza commented, for the adoption of Euro 6, precise tests and measurements were carried out, taking into consideration that refueling without the ultra-low sulfur diesel (ULSD) required for these configurations, and where a load with diesel other than ULSD would not have serious effects, an analysis of the routes or locations for refueling must be carried out.
“This first part of the year will be heavily driven by Euro 6, but given some elements such as the 5-6% or, in some cases, up to 10% performance benefit, it depends on the business model ,” added Jorge Navarro.
From the executive’s perspective, the second half of the year will be over once the period of uncertainty is over and the time comes for fleet renewal, which will not be able to stop the process.
To serve the market, Scania has configured its portfolio to address the market that has adopted cab-over models, which in Mexico already represent more than 20% of total sales among all participants in the sector.
“In Scania’s case, we have segments and applications where the full truck has been most accepted . We have six configurations, but the most accepted are the full truck (double articulated), heavy and light, mixed, and single-bed,” explained Scania’s commercial director.
