Opel Astra Plug-in Hybrid vs Peugeot 308 PHEV: the 2026 Stellantis plug-in compact showdown

Within the Stellantis group there are rivalries that are fought almost within the family, and this is one of the clearest. The Opel Astra Plug-in Hybrid and the Peugeot 308 PHEV share the EMP2 platform, the same 196 CV powertrain and even the same 17.2 kWh battery. On paper, they should be two practically identical cars. In practice, there are nuances that do matter when it comes to signing the contract.

Opel Astra Plug-in Hybrid, from ≈35,000 €: German restraint with a Stellantis stamp

The Astra opts for a restrained, almost understated look, inheriting the tradition of Rüsselsheim even though it is now built under Stellantis codes. It does not set out to surprise with the dashboard or with daring lines: it aims to make the driver feel on familiar ground from the first kilometre. In our view, this is a philosophy that works well for those who prioritise function over visual spectacle.

Peugeot 308 PHEV, from ≈33,000 €: the i-Cockpit as its signature

The 308 plays a different card: the i-Cockpit, with its small, low steering wheel and digital instrumentation peeking over the top of it, is the first impression it makes when you sit down. Love it or hate it, there is no middle ground with this driving position, but it is what visually sets the French compact apart from any other car in its class, including its Stellantis cousin.

Powertrain and platform: why they share almost everything

It is no coincidence that the power figures match to the last unit. Both use the 1.6 turbo set-up with an integrated electric motor, 360 Nm of torque and a 17.2 kWh battery under the floor, mounted on the same EMP2 platform we already know from other models in the group. The 0-100 km/h sprint takes around 7.6 seconds in both cases, and top speed is 225 km/h. Mechanically, choosing one over the other is almost a matter of faith in the badge.

Electric range: minimal differences

The difference here is very small. The Peugeot 308 PHEV is homologated for up to 85 km in electric mode, compared with up to 84 km for the Opel Astra Plug-in Hybrid. In practice these figures are virtually identical; in day-to-day use, such as short commutes and overnight charging at home, both cover most urban journeys without touching the combustion engine. For anyone looking to make the most of the CERO label, the two start from a very similar position.

Design and driving position: restraint versus character

The Astra stays on conservative ground: conventional dashboard, plenty of physical controls and ergonomics that need no adaptation period. The 308, with its i-Cockpit, requires getting used to the small steering wheel and to looking at the instrumentation over the top of it rather than through it. It is a matter of taste, but it is worth trying before buying, since not everyone is comfortable with that posture.

Price and versions: who starts with the economic advantage

The Peugeot 308 PHEV starts at around 33,000 € RRP (with promotions), while the Opel Astra Plug-in Hybrid comes in from approximately 35,000 € with discounts. The difference is not trivial, although it should be remembered that these figures are indicative (recommended RRP or with campaigns), exclude all dealer discounts, and that both models may benefit from the current Plan Auto+ — check the updated amount on the official website before settling on a final price.

Which one to choose? HighMotor’s verdict

If the priority is keeping the budget in check, the Peugeot 308 PHEV comes out slightly ahead with a lower entry price. But the Opel Astra Plug-in Hybrid is not a second-tier rival either: its conventional driving position and restrained design may matter more than any technical nuance for anyone who does not want surprises when they sit down. We did a similar exercise when comparing the Peugeot e-308 vs the Opel Astra Electric in its 100% electric version, and the conclusion is the same: within Stellantis, the final decision tends to come down to character, not the spec sheet.
