Our experiences so far
In our driving report published on 7 October 2025, we described the comfortable suspension, light steering and smooth transition between electric and petrol power. We also appreciated the space in the rear seats. These impressions provide context; we recommend a test drive on your usual route to help you decide.
Try out the operation of the display, seating position, visibility when parking and the assistance systems. If necessary, take strollers or frequently transported luggage with you. The current Swiss data sheet states 425 liters of trunk volume for Boost and Design and 450 liters for Comfort with the rear seats up.
Understanding range, charging and consumption
WLTP values are used for comparison. Cold weather, highway speed, load and heating usage influence the actual electric range. Plan a reserve for your commute and check where the vehicle can charge reliably.
According to the Swiss data sheet, all three versions charge with up to 11 kW AC or 18 kW DC. The real charging performance depends, among other things, on the battery and charging station. In everyday life, regular charging at home or at work is often more important than a quick charging stop on the go.
For a plug-in hybrid, weighted WLTP consumption differs from consumption in hybrid operation. One fuel-consumption figure alone cannot describe your everyday use. Consider petrol and electricity use together, including the share of driving done electrically. A test drive and the specific vehicle data sheet can help you assess your needs.
What to check before buying
- Access to charging: Does regular charging fit into your daily routine? Without a charging space, you should also compare a full hybrid.
- Version: Do the drive, model year and equipment in the specific advertisement match your requirements?
- Delivery: Is the vehicle already on site or will it be purchased to order?
- Warranty: Ask for the warranty duration, start date, mileage limit and claims process for this specific vehicle.
- Used vehicle: Check service history and battery condition. A battery certificate can supplement the assessment.
