Transit Custom PHEV Long-Term Review: Real-World Economy

The Ford Transit Custom PHEV delivers competitive fuel economy comparable to diesel models in everyday scenarios, while preserving full load-carrying capabilities essential for commercial operations. This plug-in hybrid van combines a petrol engine with electric propulsion for versatile performance across urban and longer routes.

Powertrain Design and Operation

At the heart of the Transit Custom PHEV lies a sophisticated plug-in hybrid system featuring a 1.0-litre EcoBoost three-cylinder petrol engine paired with an electric motor powered by an 11.8kWh lithium-ion battery. The petrol unit functions solely as a generator, charging the battery and supporting the electric motor that directly drives the front wheels, minimizing transmission losses compared to traditional hybrids.

This setup enables zero-emission electric-only driving for short distances, ideal for city deliveries, before seamlessly transitioning to hybrid mode. Ford claims up to 35 miles of electric range under WLTP testing, though real-world figures vary significantly based on temperature, load, and driving style. The system supports regenerative braking to recapture energy during deceleration, extending battery life on stop-start journeys.

Real-World Fuel Efficiency Across Seasons

Over 5,858 miles of mixed-use testing, the van achieved an average of 42.4mpg, trailing Ford’s 52.3mpg claim but matching or exceeding some diesel variants. Performance peaked in warmer weather at over 66mpg during local runs, dropping to 37.3mpg with increased motorway travel.

• Winter Performance: Cold temperatures reduced electric range to about 15 miles due to battery inefficiency in freezing conditions, without pre-heating capability, leading to earlier petrol engine activation.
• Spring/Summer Gains: Milder weather boosted EV range beyond 25 miles, enhancing overall economy for short trips.
• Highway Impact: Extended motorway use diluted efficiency as the range-extender engine worked harder, though still competitive against non-hybrid diesels.

For operators with access to charging, regular plugging in maximizes savings, particularly for routes under 20 miles. Without it, efficiency aligns closely with conventional petrol or diesel powertrains.

Electric Range: Expectations vs. Reality

Advertised at 26-35 miles of EV operation, the PHEV’s battery supports typical daily tasks like shop runs or local services. However, real-world tests revealed limitations: one 244-mile journey depleted the battery after just 23 miles despite indications of 30 miles available, shifting to petrol mode with noticeable performance change.

This table summarizes tested outcomes, highlighting the PHEV’s strength in urban settings where charging is feasible.

Driving Dynamics and Load Handling

Despite the battery’s added weight, handling remains composed, thanks to independent rear suspension that maintains stability under load or on twisty roads. The electric motor’s instant torque provides brisk acceleration from stops, mimicking a large SUV more than a traditional van, with smooth power blending.

Payload capacity matches diesel models at around 1,000kg, with no compromises on cargo space—the battery is positioned without encroaching on the load area. Towing remains robust, appealing to trades needing versatility. Regenerative braking can feel abrupt initially but aids efficiency. The petrol engine’s three-cylinder note becomes audible in hybrid mode, though less intrusive than expected.

Cabin Comfort and Technology Features

The interior boasts a 13-inch touchscreen with intuitive Ford SYNC system, supporting wireless connectivity, though occasional phone pairing glitches occur. Safety aids like adaptive cruise and lane-keeping enhance long-haul comfort, while ergonomic seating and ample storage suit all-day use.

Practical touches include multiple USB ports and a flat load floor. Ride quality absorbs bumps well unladen but firms up with payload, prioritizing durability over luxury.

Running Costs and Maintenance Outlook

Service intervals span 12 months or 30,000km, with five-year costs estimated at $2,500—lower than many diesels due to fewer oil changes and hybrid simplicity. Compared to the electric E-Transit Custom ($1,200 over five years), the PHEV balances upfront cost with refueling flexibility.

Lower emissions qualify for urban low-emission zones, reducing congestion charges for city-based fleets. Fuel savings shine for short-haul operators who charge daily, potentially undercutting diesels by 10-25mpg in optimal conditions.

Suitability for Fleets and Tradespeople

Ideal for local trades with charging access, the PHEV cuts emissions and fuel bills without range anxiety of full EVs. For wider operations, its hybrid fallback ensures reliability. Drawbacks include limited EV range for long days and higher purchase price versus diesels.

Ford’s updates, like a 2.5-litre engine option and faster charging (under 4 hours on domestic AC), address earlier models’ quirks, boosting appeal.

Pros and Cons Overview

• Pros: Strong urban efficiency, full payload retention, smooth EV driving, competitive costs.
• Cons: Cold-weather range drop, engine noise in hybrid mode, below-claimed MPG on highways.
