Peugeot Revises Plug-In Hybrid Power Ratings Under Euro 7 Rules

Peugeot updates plug-in hybrid power ratings using the new GTR21 protocol ahead of Euro 7. Learn how the changes affect official figures and model naming.

Peugeot has revised the official power figures of its plug-in hybrids without changing the cars themselves — a move driven by the upcoming Euro 7 regulations. The company has already begun applying the new GTR21 protocol, which fundamentally changes how combined hybrid power is calculated.

Several models are affected. The Peugeot 3008 and 5008 plug-in hybrids are now certified at 225 hp, while the Peugeot 408 plug-in hybrid is rated at 240 hp. These updates do not reflect any technical modifications: performance, fuel consumption, and emissions remain unchanged. What has changed are the certified figures — and, accordingly, the commercial names of the models.

This shift goes beyond branding. The Euro 7 standard, set to apply from late 2026 for new models, introduces a unified framework for vehicle certification, including hybrid power output. At its core is the GTR21 regulation, which calculates combined power based on real operating conditions rather than a simple sum of engine and electric motor outputs.

The distinction is significant. Previous figures could reflect theoretical maximums that are not always achievable in practice, as hybrid systems cannot consistently deliver peak output from all components simultaneously. Battery limitations and energy management systems play a key role. The new methodology aims to produce figures that are more realistic and directly comparable across manufacturers.

For customers, this means greater transparency, even if the numbers appear lower than before. Importantly, the real-world driving characteristics of the vehicles remain unchanged — the adjustment is purely regulatory and concerns how performance is measured and presented.

Peugeot is among the first manufacturers to implement these changes ahead of the Euro 7 rollout, effectively aligning its lineup with future requirements before they become mandatory.
