Large vans are often judged on their sheer carrying capacity, but smart operators know that fuel efficiency is just as crucial. Finding a large van that balances power and economy is essential for businesses of all sizes. If you’re in the market to lease a van and are focused on keeping running costs down, understanding which models offer the best MPG is a great starting point. Vanarama’s expert, Tom Roberts, has delved into the data to highlight five large vans that excel in fuel economy, with a particular focus on the impressive Mercedes Big Van – the Sprinter.
Considering the demanding tasks they undertake – transporting substantial loads over long distances – the popularity of large vans on UK roads is no surprise. From multinational fleets to independent tradespeople, these vehicles are the backbone of numerous businesses. However, regardless of company size, fuel expenditure significantly impacts the bottom line. Therefore, when selecting a large van, fuel efficiency is a paramount consideration alongside payload and load volume.
While modern large vans boast similar comforts like well-equipped cabins and infotainment systems, differentiating factors are crucial for informed decision-making. Beyond payload and load volume, fuel efficiency stands out as a key differentiator in the large van market. Let’s explore the top 5 most fuel-efficient large vans available in the UK today, paying close attention to how the Mercedes big van, the Sprinter, performs in this competitive arena.
Understanding the MPG Figures
Before diving into the rankings, it’s important to clarify the MPG figures used. All MPG ratings cited are official WLTP (Worldwide Harmonised Light Vehicle Testing Procedure) figures. Other data, such as torque, are from manufacturer sources. Where manufacturers provide a range of figures, a midpoint has been used. For unobtainable manufacturer data, figures are sourced from WhatVan? magazine, using data from Glass. It’s also crucial to note that MPG can vary significantly within a model range based on van size, weight, and engine. This list prioritizes the most economical variant of each model for a fair comparison.
The Top 5 Most Economical Large Vans
1. Ford Transit – 43.5mpg

Leading the pack with a notable margin is the iconic Ford Transit, achieving an impressive 43.5mpg when equipped with the 105PS Ecoboost Euro 6.2 diesel engine. Ford has emphasized the efficiency of this engine, and its class-leading fuel economy validates these claims. Despite its modest power output, 310nm of torque ensures effortless urban driving. With CO2 emissions of 221g/km, the Transit also stands out as a cleaner option in the large van segment.
2. Fiat Ducato – 34.4mpg

The Fiat Ducato, in its latest iteration, secures the second spot with 34.4mpg. Previously utilizing proprietary engines, Fiat has now aligned with its Stellantis counterparts, Peugeot and Citroen, adopting the group’s 2.2-litre ‘Multijet’ engines. Possibly through figure presentation or minor adjustments, the Fiat Ducato slightly outperforms its French siblings in this fuel efficiency ranking. The 120hp version achieving this MPG also boasts the lowest CO2 emissions in this list at 220g/km, narrowly beating the Transit. Furthermore, the 320nm of torque provides ample power for demanding operations.
3. Mercedes-Benz Sprinter – 32.8mpg

The Mercedes-Benz Sprinter, a renowned Mercedes big van, achieves an excellent 32.8mpg, securing a strong third place. While this figure is for the smallest variant, the 215 L1H1, even the largest 317 L4H2 Sprinter manages a respectable 30mpg. This is particularly noteworthy considering the 215’s 2.0-litre diesel engine delivers 150hp, significantly more power than the Transit and Ducato. Its torque output of 340nm is also higher. With CO2 emissions at 225g/km, the Mercedes Sprinter demonstrates an impressive balance of power and efficiency. The Sprinter’s reputation for robustness and reliability, combined with its proven fuel economy, makes it a highly compelling option for businesses focused on cost-effectiveness. For businesses seeking a Mercedes big van that minimizes fuel costs without compromising on performance or durability, the Sprinter is a leading contender.
4. Peugeot Boxer / Citroen Relay – 32.8mpg

Sharing third place with the Mercedes Sprinter are the Stellantis twins, the Peugeot Boxer and Citroen Relay. These vans are ideal for businesses prioritizing payload and load space while maintaining tight control over running costs. The 120hp version of their 2.2-litre diesel engine achieves this MPG, producing 310nm of torque, slightly less than the Fiat Ducato’s modified version. Notably, these engines are Euro 6.4 compliant, a forward-thinking feature in the van market, potentially enhancing their future-proof appeal. However, their CO2 emissions are quoted at 273g/km, which is higher compared to others on this list.
5. Vauxhall Movano – 32.3mpg

A popular choice among tradespeople, the Vauxhall Movano completes the top 5. Now part of the Stellantis group, the Movano shares its platform with the Peugeot Boxer, Citroen Relay, and Fiat Ducato. While the 120PS version achieves 31mpg, slightly outside the top 5, the 140PS engine manages 32.3mpg with CO2 emissions of 240g/km. Vauxhall does not currently publish torque figures, but it’s likely to be similar to the Peugeot and Citroen engines, offering around 340nm.
Understanding MPG Calculation
The MPG figures presented are based on the official WLTP standards, ensuring consistent testing across all manufacturers. This standardized testing allows potential buyers to effectively compare fuel economy between different models.
Real-world MPG can be influenced by factors like payload, weather, and driving style. Therefore, while WLTP figures provide a valuable benchmark for comparison, actual fuel consumption in daily use may vary. It’s also worth noting that WLTP figures are generally lower than the older NEDC standards, reflecting a more realistic assessment of fuel consumption under modern driving conditions.
Tom’s Takeaways
With the UK government’s target of phasing out combustion engine vehicle sales by 2030, the long-term relevance of MPG ratings is limited. However, for businesses choosing a new van now, fuel costs remain a critical factor.
This top 5 list showcases the large vans leading in MPG, offering a range of choices to suit diverse needs. For payload and load space, the Stellantis group vans are strong contenders. If volume is paramount, the L4 Mercedes Sprinter stands out with its vast capacity. However, for the reassurance of a legendary large van with excellent fuel economy, the Ford Transit takes the top spot. The large van market offers a wealth of options, ensuring businesses can find a van that aligns perfectly with their operational requirements and budget. The Mercedes big van Sprinter, with its blend of efficiency, power, and reputation, remains a compelling choice within this diverse sector.

Economical Large Van FAQs
Q1: Which fuel types offer the most MPG and why?
Diesel vans generally offer better MPG than petrol equivalents due to diesel fuel’s higher energy density and more efficient combustion process.
Q2: Does my driving affect my van’s MPG?
Yes. Aggressive driving habits such as hard acceleration and braking significantly increase fuel consumption.
Q3: How can I drive more economically and save fuel?
Adopt smooth driving techniques: anticipate braking, accelerate gently, maintain lower top speeds, and avoid harsh acceleration. Imagine driving with a bowl of water on the passenger seat – smooth, steady driving makes a noticeable difference.
Q4: What is the difference between WLTP and NEDC?
WLTP replaced the outdated NEDC (New European Driving Cycle) to provide more realistic MPG figures reflecting real-world driving conditions. WLTP uses dynamic driving cycles tailored to vehicle types, unlike NEDC’s single cycle.
Q5: What are Euro 6 standards and why do they matter?
Euro 6 emission standards are the latest regulations governing permissible emission levels for diesel engines. With the growth of low emission zones in urban areas, non-Euro 6 compliant vans face increasing restrictions and potential penalties. Leasing a new van ensures compliance with the latest emission standards.
