The DS 7 Crossback Ultra Prestige petrol variant delivers a compelling blend of French luxury and capable performance, particularly shining during long-distance motorway drives. However, in a segment dominated by agile premium SUVs, it struggles to match the all-around prowess of top competitors.
Engine Performance and Power Delivery
At the heart of this top-spec model lies the PureTech 225 1.6-litre turbocharged petrol engine, producing 222bhp and ample torque for effortless acceleration. This powertrain propels the DS 7 from 0-62mph in 8.3 seconds, a figure that feels accurate in real-world testing, with seamless power delivery through an eight-speed automatic transmission.
Unlike diesel alternatives, the petrol unit offers refined smoothness, avoiding the typical clatter associated with oil-burners. It’s front-wheel drive only, which contributes to respectable handling without the added weight of all-wheel drive systems found in some rivals. Top speed reaches 141mph, making it suitable for high-speed cruising.
- 0-62mph: 8.3 seconds
- Top speed: 141mph
- Transmission: 8-speed automatic, praised for silky shifts
Drivers note the engine’s enthusiasm without excessive noise intrusion, maintaining cabin serenity even under hard acceleration. A less powerful PureTech 180 option exists but offers minimal savings, at just £1,500 less, with similar economy figures.
Fuel Efficiency and Running Costs
Official combined economy stands at around 48.7mpg for the petrol model, aided by its front-wheel-drive setup and efficient turbocharging. Real-world tests confirm viability, with motorway runs achieving close to 48.6mpg at 70mph. However, this lags behind diesel variants’ 57.6mpg claims and plug-in hybrids’ impressive 166-235mpg WLTP figures.
| Powertrain | Combined MPG (WLTP) | CO2 Emissions (g/km) |
|---|---|---|
| PureTech 225 Petrol | 48.7 | 134 |
| BlueHDI 180 Diesel | 57.6 | 128 |
| E-Tense PHEV | 166-235 | N/A |
Petrol ownership increases fuel expenses compared to diesels, though three-cylinder models promised for later promised better frugality. Road tax starts low at £160 for the first year on diesels, but petrol’s higher CO2 pushes costs up slightly. For urban-focused buyers, petrol suits short trips better than motorway-optimized diesels.
Ride Quality and Handling Dynamics
The DS 7’s Active Scan Suspension uses a forward-facing camera to scan road surfaces and adjust damping preemptively, excelling at 40mph where it absorbs imperfections superbly. In Comfort mode, it delivers a supple ride, contrasting stiffer German rivals.
Yet inconsistencies mar the experience: motorway travel feels wallowy, while urban speeds transmit bumps and shimmies. Handling is competent but not sporty, with secure grip yet limited agility against benchmarks like the Audi Q5 or BMW X3. No four-wheel drive on petrol models keeps weight down but sacrifices off-road versatility.
- Strengths: Supple at moderate speeds, quiet cabin
- Weaknesses: Wallowy on highways, fidgety in town
Interior Luxury and Space
Step inside, and the DS 7 assaults the senses with opulent materials: Nappa leather, Alcantara, and intricate stitching create a classy haven defying typical SUV austerity. The Ultra Prestige trim elevates this with massaging seats, premium audio, and ambient lighting.
Rear space impresses, accommodating adults comfortably, while the 555-litre boot edges out the Audi Q5’s capacity. Infotainment features a 12-inch touchscreen, though some find the interface less intuitive than rivals. Build quality feels premium, knocking on luxury doors without fully entering.

Spacious and refined, it’s a pleasant place for long journeys.
Design and Practicality
Externally, the DS 7 boasts striking LED lighting, bold creases, and a distinctive grille, setting it apart in a sea of conservative crossovers. At 4.6 meters long, it’s family-sized yet maneuverable.
Practical touches include a hands-free tailgate and versatile seating. However, the lack of 4×4 on petrol limits light off-road use, positioning it firmly as a road-biased luxury cruiser.
Safety and Technology Features
Standard kit on Ultra Prestige includes adaptive cruise control, lane-keeping assist, and a 360-degree camera. Euro NCAP ratings highlight strong crash protection, though active safety scores vary by spec. The Active Scan system indirectly aids safety by smoothing rides over hazards.
Competitor Comparison
In the premium mid-size SUV arena, the DS 7 faces stiff opposition:
| Model | 0-62mph | MPG | Boot Space (L) |
|---|---|---|---|
| DS 7 PureTech 225 | 8.3s | 48.7 | 555 |
| Audi Q5 | ~7s | ~50 | 550 |
| BMW X3 | ~6s | ~45 | 550 |
The DS offers unique styling and ride comfort but trails in dynamic talent and residual values.
Pricing and Ownership
Starting above £40,000 for Ultra Prestige petrol, it’s competitively priced against premium peers but pricier than entry DS 7s at £27,790. PCP deals minimize monthly costs, though diesels or incoming PHEVs may appeal for efficiency.
Pros and Cons
- Pros: Luxurious interior, smooth petrol power, generous space
- Cons: Inconsistent ride, higher fuel costs, less agile than rivals
