The Best Hybrid SUV for Towing in the UK: A Deep Dive for Caravanners in 2026
If you're a UK caravanner in 2026, you're probably feeling the shift. Diesel SUVs that once ruled the towcar scene are becoming rarer thanks to tightening emissions rules, rising fuel costs, and the ever-expanding ULEZ and Clean Air Zones. Plug-in hybrid (PHEV) SUVs have stepped up as the smart alternative: they blend strong electric torque for effortless getaways, decent efficiency when the battery is depleted, low Benefit-in-Kind (BIK) tax for company car drivers, and enough range to make a full tank last longer on long hauls to the Lake District or ferry crossings to France.
But not all PHEVs are created equal when it comes to towing. A caravan adds significant weight, changes the dynamics, and demands stability at 60mph on the M6, hill-start capability on steep campsite entrances, and reliable performance when the battery runs flat. We've dug into the latest 2025/2026 Towcar of the Year results from the Caravan and Motorhome Club, Practical Caravan tests, Auto Express awards, real-world owner feedback, and UK-spec data to find the stand-out hybrid SUV for towing.
The short answer? The Volvo XC90 T8 Plug-in Hybrid remains one of the most balanced and highly awarded options for typical British caravanners. But the BMW X5 xDrive50e pushes it hard if you want more outright power and a higher towing limit. Let's break it all down in detail.
Why PHEVs Make Sense for UK Towing Right Now
Traditional diesels offered effortless low-rev torque, but PHEVs deliver instant electric shove from standstill — perfect for merging onto motorways with a loaded twin-axle caravan or pulling away from junctions. Many deliver 30–50 miles of real-world electric range, meaning you can commute or do short family runs emission-free and avoid ULEZ charges. Once the battery is empty, the petrol engine takes over, and modern PHEVs still achieve respectable mid-20s mpg while towing (better than many older petrols).
Company car users benefit hugely from low BIK rates (often under 10%), while private buyers enjoy lower road tax and the option to charge at home or destination sites. The downside? PHEVs are heavier due to the battery, which can affect payload and noseweight limits, and towing economy drops noticeably when running on petrol alone.
The key rule of thumb for safe towing in the UK is the 85% matching guideline: your caravan's Maximum Technically Permissible Laden Mass (MTPLM) should ideally be no more than 85% of the car's kerbweight. This leaves headroom for stability and legal compliance. Check your cars maximum towing weight here.
The Top Contender: Volvo XC90 T8 Plug-in Hybrid AWD
Priced from around £77,000–£85,000 depending on spec (Plus or Ultra trim), the XC90 T8 is a seven-seater PHEV that consistently impresses in towing tests. It won the Hybrid Towcars category in recent Caravan and Motorhome Club awards and has been highly commended in Auto Express evaluations.
Powertrain and Performance
- 2.0-litre turbocharged petrol engine + rear electric motor
- Combined output: approximately 449–455bhp and massive torque (around 523 lb-ft system total)
- The electric motor alone provides 309Nm from 0rpm — that instant response makes a huge difference when pulling away or overtaking with a caravan
- Official EV range: up to 40–50 miles real-world (depending on weather, driving style, and load)
- 8-speed automatic gearbox with all-wheel drive
Towing Specs
- Braked towing capacity: 2,400kg
- Noseweight limit: around 110kg
- Kerbweight: approximately 2,297kg
- 85% match: roughly 1,952kg — ideal for most single- and many twin-axle caravans like Bailey Unicorns, Swift Conquerors, or Coachman models in the 1,600–2,000kg MTPLM range
On the Tow: Real-World Behaviour Testers and owners report excellent high-speed stability. The air suspension (standard on higher trims) levels the car beautifully, keeping body movement controlled over undulations and motorways. Even in windy conditions, the XC90 feels planted with minimal snaking. The electric motor handles initial acceleration smoothly, often allowing short stretches of electric-only towing on flat roads before the petrol engine chimes in.
Hill starts are effortless thanks to the combined torque. Reverse manoeuvring on campsites is aided by superb 360-degree cameras and precise steering. When the battery depletes, the 2.0-litre engine provides strong mid-range pull, though it's noisier than when the hybrid system is active. Real-world towing economy: owners report mid-20s mpg with a healthy battery charge, dropping to high teens when running purely on petrol — still competitive for a near-2.5-tonne luxury SUV.
Everyday Practicality Beyond towing, the XC90 shines as a family hauler. Seven proper seats, a vast boot (up to 650+ litres with the rearmost row folded), and a calm, premium Scandi interior make long journeys relaxing. It's refined in EV mode, quiet on the motorway, and packed with safety tech that gives peace of mind when kids and kit are on board. For company car drivers, the low BIK is a big win.
Potential Drawbacks The 2,400kg limit means it's not suited to the heaviest outfits (over 2,200kg MTPLM). It's also expensive to buy outright, though strong residuals help. Some owners note that payload can feel tight when fully loaded with seven people plus luggage.
Strong Rival: BMW X5 xDrive50e – The Performance King
If you need more towing headroom or enjoy a more dynamic drive, the BMW X5 xDrive50e is arguably the strongest PHEV tug overall.
Key Specs
- Price: from around £82,000
- Power: 489bhp combined (3.0-litre straight-six petrol + electric motor)
- Towing capacity: 2,700kg braked
- Kerbweight: ~2,495kg
- 85% match: ~2,121kg
- EV range: realistic 45–55 miles
Testers praise its rock-solid stability, controlled suspension, and effortless performance. It can tow on electric power for extended periods and delivers massive overtaking punch when both power sources work together. It's firmer and more driver-focused than the Volvo, making it rewarding on twisty roads even with a caravan. Fuel economy while towing: around 40+ mpg with battery assistance, dropping to low-20s or high-teens when depleted.
It's a superb all-rounder but slightly less practical for large families (five seats standard, though spacious). If you tow big and value performance, this is hard to beat.
The Thrill Option: Porsche Cayenne E-Hybrid
The Cayenne E-Hybrid (often based on the V6) has previously won overall Towcar of the Year honours and remains a commendation-level performer. With up to 3,500kg towing in some configurations and razor-sharp handling, it turns towing into something enjoyable rather than a chore. The cabin is premium, the ride composed, and the performance addictive.
Downsides? Higher price, less family-focused practicality (no seven seats in most versions), and you're paying for the Porsche badge and driving dynamics. Great if you want to enjoy the journey as much as the destination.
Budget-Friendly Alternative: Ford Kuga PHEV (or Full Hybrid)
For those on a tighter budget (under £40k–£45k), the updated Ford Kuga PHEV is worth a serious look. Recent revisions have boosted its towing capacity to 2,100kg — impressive for its size.
It's nimbler than the big premium SUVs, making it easier around campsites and on narrow UK lanes. Real-world tests show strong efficiency (30+ mpg towing with battery) and decent stability for lighter caravans. The full-hybrid (non-plug-in) AWD version also reaches 2,100kg and offers simpler ownership. Not as luxurious or stable at high speeds with heavy loads, but excellent value and practical for everyday family life.
Other Notable Mentions
- Range Rover Sport PHEV: Plush ride, strong power, good stability — but higher running costs and complexity.
- Toyota/Lexus hybrids (e.g., RAV4 or RX 450h+): Ultra-reliable, but generally lower towing limits than the Europeans.
- Emerging options like the refreshed Hyundai/Kia PHEVs are improving, but they often trail the premium players in outright towing prowess.
Final Verdict: Which Hybrid SUV Should You Choose for Towing?
For most UK caravanners — balancing family practicality, stability, efficiency, low tax, and typical caravan weights (under 2,200kg) — the Volvo XC90 T8 PHEV is still the standout choice in 2026. It does almost everything brilliantly without major compromises, and its repeated success in hybrid towcar categories proves the point.
If you regularly tow heavier outfits or crave more performance and a sportier edge, go for the BMW X5 xDrive50e. It's one of the most capable tow vehicles of any powertrain. For pure driving enjoyment with a caravan, the Porsche Cayenne E-Hybrid is in a league of its own.
Whichever you pick, test tow if possible — many dealers and caravan clubs offer matching days. Factor in a proper towbar installation, weight distribution hitch if needed, and always check noseweight and payload.
The hybrid era of towing is here, and it's surprisingly capable. Plug in, hitch up, and enjoy those caravanning adventures with a clearer conscience and lower tax bill.
