The segment that carries the weight
If policy targets are to translate into measurable carbon reduction, attention must focus on the vehicles doing the heaviest work.
Government data shows articulated trucks moved 63% of all goods lifted in Great Britain last year – 998 million tonnes. Within that, articulated HGVs over 26 tonnes, most commonly in 6x2 configuration, account for approximately 60% of CO2 emissions from the road freight sector.
This is the mainstream of UK logistics: supermarket trunking, container haulage, pallet networks and long-distance general haulage. It is also where diesel remains embedded.
According to the latest SMMT figures, battery-electric HGV sales in 2025 rose by 171% year-on-year. While that still represents just 1.4% of the market, demand is beginning to grow. Faster infrastructure rollout, grid connections and planning approvals will be needed to support wider adoption, while capital cost and payload sensitivity remain key concerns for operators. Continued advances in truck technology will also play an important role in enabling the transition. Renault Trucks' decision to expand its long-haul electric offer – introducing significantly increased range in a 6x2 tractor configuration – is a notable example of that progress.
Engineering for long-haul duty cycles
At Solutrans in November last year, Renault Trucks introduced three additions to its electric tractor line-up:
-
E-Tech T780 6x2, up to 600km range
-
E-Tech T585 6x2, up to 460km range
-
E-Tech T540 4x2, up to 450km range
The two new 6x2 tractors are built around an integrated e-axle. Electric motors and transmission are positioned at the rear axle, enabling battery capacity to be distributed efficiently along the chassis.
Battery capacities stand at 585kWh for the T585 and 780kWh for the T780. Both use NCA battery systems covered by an eight-year or one-million-kilometre guarantee.
The objective is clear: align electric capability with the operational profile of UK's 6x2 trunking fleets.
E-Tech T585: The likely UK 6x2 volume model
Renault Trucks expects the E-Tech T585 to see the strongest uptake in the UK for the 6x2 models. It offers a stated 23-tonne payload alongside up to 460km of range and provides 80% of the payload capacity of a comparable 6x2 Renault Trucks diesel.
Clarke says. "Our assessment is that most operators do not operate at maximum GCW on 6x2 diesel units. Based on the offering today in the market, we believe this is simply the most productive BEV in the industry in the UK."
The commercial argument rests on real-world loading patterns rather than theoretical maximum weights. Fleets consistently operating at full gross combination weight will need to evaluate carefully. Others may find the differential less significant than anticipated.
E-Tech T780: Extended range application
The E-Tech T780 increases battery capacity to 780kWh, extending range up to 600km.
The additional range provides greater flexibility for longer trunking operations or routes with limited charging access.
Charging strategy and MCS readiness
Both long-haul E-Tech T models are equipped for Megawatt Charging System (MCS) capability of up to 720kW. Renault Trucks states this can add approximately 350km of range during a 45-minute statutory driver break. CCS charging is possible up to 350kW.
"Customers that are buying trucks today may be using those vehicles for the next 10 years, and they need to start thinking MCS," says Clarke. "It will be commonplace in the next few years. For some operators, the next buying cycle may be the point where diesel is no longer the default choice."
While MCS infrastructure deployment across the UK is just starting to roll out, commercial vehicle readiness is increasingly regarded as a necessary hedge against future network expansion.
E-Tech T540 4x2: Regional focus
The E-Tech T540 becomes the new 4x2 offer with up to 450km on a single charge for regional and urban distribution work.
For many operators, regional trunking represents the most immediate electrification opportunity. Predictable routes and depot returns simplify charging integration. "It's about specifying the right truck for the job," notes Clarke.
Aftersales and operational continuity
Alongside the vehicles themselves, Renault Trucks supports the range with Optifleet, it's 'turnkey fleet management solution' for planning and monitoring.
"Thanks to our years of experience in electromobility, we've developed a range of support services to help operators transition to electric with real confidence," Clarke adds. "These include our Driver App, which allows drivers to check charging status and remotely prepare the vehicle; as well as our Serenity Pack, which provides full contract coverage including wear, repair and maintenance; together with a traction battery performance commitment and active monitoring of the energy storage system. Our Serenity Pack also provides data support and user-friendly dashboards to ensure operators maximise the performance of their electric vehicles.
"Maintaining uptime remains fundamental. Predictive maintenance and remote diagnostics are designed to reduce unplanned downtime, which is critical for operators evaluating the move to electric," he adds.
Making the move
The 6x2 articulated tractor is the backbone of UK freight and one of its largest emissions sources. Electrifying this segment is central to any credible net zero pathway.
With its latest E-Tech additions, Renault Trucks is putting long-haul 6x2 electric tractors onto the agenda for UK fleet planning.
