DS 4 Plug-in Hybrid Pallas long-term test | Range and mpg

Our DS 4 uses a plug-in hybrid powertrain shared with numerous other Stellantis models. It’s based around a 1.6-litre turbocharged petrol engine and an eight-speed automatic gearbox with an integrated electric motor.

The total power output is 225PS, which gives a brisk 0-62mph acceleration time of 7.7 seconds.

A 12.4kWh battery is integrated into the car’s chassis and enables a zero-emission range of 34 miles (WLTP). Official CO2 emissions are 33g/km, so for the 2025/26 tax year the DS 4 Plug-in Hybrid attracts a 13% benefit-in-kind tax rate. For our car, that means monthly bills of around £91 for a 20% taxpayer.

The claimed fuel economy figure is 232mpg, but we’re not expecting anywhere near that in the real world.

Since joining our fleet the DS 4 has been averaging 48.6mpg.

Our experience is also showing a realistic electric range of about 22 miles, rather than the claimed 34.

It’s enough for short commutes, but on longer journeys the engine does most of the work. This brings down the average efficiency quite considerably. When a colleague borrowed the car for a week, who does lots of short journeys, he managed to return 60mpg. So driving patterns make a big difference.

The 225PS powertrain has good performance. Even in electric mode it’s fine for nipping about. When you do want full power there can be a little delay from the time you prod the throttle to when the engine delivers the goods. When it does get going, the acceleration is brisk.

Refinement levels are high and in normal driving it’s difficult to tell if the engine is on or not.

When it comes to charging, our car has the optional 7.4kW on board charger meaning it can make full use of a typical home wallbox. A full charge takes around two hours here. If you only have a three-pin plug then it’ll take seven hours.

Without the upgraded charger the DS 4 can only charge at 3.7kW, with a full charge taking almost four hours.

DS 4 Pallas Plug-in Hybrid joins our fleet

There’s no escaping the fact that the DS 4 is an unconventional pick. Sitting in the premium hatchback segment its key competition includes the Audi A3, BMW 1 Series, Cupra Leon and Mercedes A Class.

And if you peek at the sales figures for each of those, you’ll find the DS lingering in shadows.

That’s a shame, though, because the DS 4 has many likable attributes. It’s the most eye catching of the bunch, for starters. That distinctive front grille, those giant LED light strips and the electrically retracting chrome door handles all set the DS 4 apart from the mainstream.

But French luxury cars have always struggled in the UK market, where people prefer gloss black trim, big wheels and sparse interiors, rather than plush upholstery and exquisite design.

The DS 4 aims to bridge that gap. It fuses French luxury with a sporty flair. Using the Stellantis EMP2 platform, which is shared with the Peugeot 308 and Vauxhall Astra, it targets the premium side of the hatchback market.

Our test model is specified in Pallas trim, which is the entry-level grade, and we’ve opted for the Plug-in Hybrid 225 powertrain.

The standard specification is generous and includes keyless entry, adaptive cruise control, LED headlights, front and rear parking sensors with reversing camera, electric folding door mirrors and a 10-inch infotainment touchscreen.

In fact, we can’t really see the advantage of paying £2,800 more for the higher-ranking Etoile trim as most of the extra features can be added to the Pallas via the £650 Comfort Pack, which includes heated front seats, a motorized tailgate and tinted rear windows.

So that’s exactly what we did. Our car also has upgraded 19-inch alloy wheels (£150) and a 7.4kW on board charger (£300).

The ‘Night Flight’ paint was an additional £645, bringing the total price to £42,375.
