Peugeot is moving early to align its plug-in hybrid lineup with upcoming European regulations, introducing revised power ratings and new model names based on the GTR21 homologation protocol.
The change comes ahead of the wider rollout of the Euro 7 emissions standard, set to take effect for new models in late 2026.
What Is Changing?
The key update centers on how combined power output is measured in plug-in hybrid vehicles. The new GTR21 protocol standardizes the calculation of total output from both the internal combustion engine and the electric motor.
As a result, Peugeot has updated the officially certified power figures of several models—without making any mechanical or performance changes. Instead, the revisions reflect a new, more consistent measurement method that will soon become mandatory across Europe.
Updated Models and Power Ratings
Three Peugeot plug-in hybrid models now carry revised power outputs and updated commercial names:
– The Peugeot 3008 Plug-in Hybrid is now rated at 225 hp (166 kW) and renamed Peugeot 3008 Plug-in Hybrid 225 Auto
– The Peugeot 5008 Plug-in Hybrid also adopts a 225 hp (166 kW) rating, becoming Peugeot 5008 Plug-in Hybrid 225 Auto
– The Peugeot 408 Plug-in Hybrid is now rated at 240 hp (177 kW), renamed Peugeot 408 Plug-in Hybrid 240 Auto
Additionally, the newer Peugeot 308 Plug-in Hybrid 195 Automatic already complies with the GTR21 protocol, signaling the brand’s broader transition across its electrified range.
No Changes to Performance or Costs
Despite the updated figures, Peugeot emphasizes that these vehicles remain technically identical. Performance, fuel efficiency, and emissions outputs are unchanged, as the update is purely related to certification methodology.
Importantly for buyers, the revised ratings also have no impact on vehicle registration costs in markets like France. Fees such as the carte grise continue to be calculated based solely on the combustion engine’s power, which has not been altered.
Preparing for the Euro 7 Era
By adopting the GTR21 protocol ahead of schedule, Peugeot is positioning itself—and its parent company Stellantis—for a smoother transition into the Euro 7 regulatory framework. The standard will apply to all new vehicle types from November 30, 2026, and to all new vehicles sold from November 30, 2027.
This early move also signals a broader industry shift toward more transparent and harmonized reporting of hybrid powertrain performance, helping consumers better compare electrified models across brands.
As the European market prepares for stricter emissions rules, Peugeot’s proactive approach highlights how automakers are already adapting not just their technologies—but also the way those technologies are measured and marketed.
