Renault Trucks E-Tech T

E-Tech T is the name Renault Trucks gives to a range of battery-electric trucks that covers both tractor units and rigids. This page covers the tractor units, which Renault offers in three versions in 2026; the E-Tech T rigid is not covered here. The E-Tech T 540 is a two-axle tractor with a central electric drive, which Renault positions for regional distribution. The E-Tech T 585 and E-Tech T 780 are 6x2 tractors built around an electric axle and aimed at long haul: the 585 at payload, the 780 at range. At IAA Transportation in Hanover in September 2026 Renault Trucks showed the T 780 with a range of up to 660 km, and gave the T 585 up to 500 km and the T 540 up to 450 km. Each figure belongs to one version, so the record above carries no range figure, and no Renault document opened for this page says what the 660 km was measured at. The E-Tech T tractors also appear as rows in a register of maker-declared values for electric tractor units.

The name is older than the long-haul versions. Series production of the E-Tech T began at Renault Trucks’ Bourg-en-Bresse plant in November 2023, as a regional truck. In November 2024 Renault announced an E-Tech T with an electric axle and a 600 km range, with orders to open in the second half of 2025. It unveiled the T 585 and T 780 on 18 November 2025 and said the three versions were “available to order now”. In February 2026 it listed the T 540, T 585 and T 780 among the electric trucks that “will go into production in 2026”, and the specification sheets in its June 2026 press kit give 2026 as the year of sale and production. Renault’s corporate electromobility page calls the 2026 start of serial production of the T 585 and T 780 “a new milestone”, without giving a date.

Renault’s IAA release of 15 September 2026 says of the E-Tech D 12T and 14T city trucks “Available now; produced at the Blainville-sur-Orne plant”, and says nothing of the kind about the E-Tech T, whose production Renault’s documents place in 2026. This record gives no production year: 2023 is the year of the name, while every figure in the record belongs to the 2026 versions.

The photograph above shows a three-axle E-Tech T rigid with a load body, in the livery of the mineral water bottler Ensinger, at the Nufam trade fair in Rheinstetten in September 2025. The model is identified by Renault Trucks Deutschland’s release of February 2025, which reports an E-Tech T with an Orten beverage body handed over to Ensinger; the truck in that release’s photographs carries the same livery and registration. That truck was delivered before Renault unveiled the T 585 and T 780, it is a rigid while all three versions on this page are tractors, and none of its figures are used here. The diesel Renault Trucks T has a record of its own, and nothing on this page is taken from it.

Overview and generations

The E-Tech T name predates the long-haul versions described on this page. Renault Trucks started series production of the first E-Tech T at its Bourg-en-Bresse plant in November 2023. Its release of 23 November 2023 describes that truck, together with the E-Tech C, as 4x2 and 6x2 tractor versions with a long cab and a 3,900 mm wheelbase, two or three electric motors developing a combined power of up to 490 kW, and four to six lithium-ion battery packs providing between 390 and 540 kWh. It gives that truck a gross combination weight of up to 44 tonnes, AC charging up to 43 kW, DC charging up to 250 kW and a range of up to 300 km on a full charge. In November 2024 Renault said it had increased the range of the E-Tech T by “integrating a new component, namely an electric axle”, and announced 600 km for a new version with orders opening in the second half of 2025. Set against the 2023 truck, the three 2026 versions on this page differ: the T 585 and T 780 are built around the electric axle, while the T 540 keeps a central drive closer to the 2023 layout. The 6x2 version of the 2023 truck predates the electric axle — our reading of the two releases — and none of its figures are otherwise used on this page.

Renault’s June 2026 press kit carries a one-page specification sheet for each of the three current versions, and the three sheets list different drivelines. The T 540’s driveline is listed as “Central Drive” with eight transmission gears, and its power take-offs as electric, mechanical and mechanical while driving. The T 585 and T 780 are listed with an “eAxle”, six gears and an electric power take-off only. The November 2025 release explains the change: the electric axle groups the motors and the transmission at the rear of the vehicle and frees the space between the side members for additional battery packs. The same release describes those packs as NCA (nickel, cobalt, aluminium) lithium-ion batteries with an L-shaped design to fit the new layout. It names that chemistry for the T 585 and T 780; the documents opened do not name the T 540’s.

Renault Trucks UK’s product page for the range states that the E-Tech T enables “up to 90% reduction in life-cycle CO₂”, without publishing what that percentage is measured against.

In November 2024 Emmanuel Duperray, Senior Vice President Electromobility, said of the driveline choice “We’re not looking to enter a race for autonomy on a single charge”, and that oversized batteries penalise the payload. The T 585 and T 780, unveiled a year later, carry that trade-off into two separate versions: the T 585 is built with more payload, the T 780 with more range, as set out below.

Cab

Two documents list the cabs differently. The June 2026 sheets give “Night & Day / Sleeper” for all three versions; the specification table in the November 2025 press kit gives the 4x2 both cabs and the 6x2 the Sleeper cab only. That same table gives the T 540’s chassis as “Medium”, in a column headed “Chassis” that the 6x2 row beside it leaves blank. What separates the two cabs is covered in truck cabs explained.

Transmission and power take-off

The June 2026 sheets head the driveline row differently by version. The T 540 is listed with “Central Drive” and eight transmission gears; its power take-offs are listed as electric, mechanical and mechanical while driving. The T 585 and T 780 are listed with an “eAxle” and six gears, and an electric power take-off only. Renault Trucks UK’s range page names the gearboxes: “Electric Optidriver CAT” for the range in general, or “Optidriver e-axle” for the T 585 and T 780 specifically.

Axles, suspension and brakes

The November 2025 release describes the rear axle fitted to the two eAxle versions, the T 585 and T 780, as lightweight, steerable and liftable, and says this axle “protects tyres during return trips at low load”. It fits the two versions with built-in air suspension and says their manoeuvrability is comparable with that of a 4x2 tractor. The documents opened do not name the configuration as pusher or tag; the two are explained in axle configurations explained. Renault Trucks UK’s range page lists full air suspension among the E-Tech T range’s features generally, without separating it by version, and says it eases docking operations. No document opened for this page gives a brake type, a disc or drum size, or a retarder or other endurance brake for any version.

Battery capacity

Each sheet has a row headed “Battery capacity”, and on two of the three sheets the figure is not the model number. The T 780 sheet reads 784 kWh, the T 585 sheet 588 kWh and the T 540 sheet 540 kWh. The November 2025 release gave the two long-haul versions 585 and 780 kWh. This record carries the sheet figures, 540 to 784 kWh, as the span of the capacities printed for the three versions; Renault’s own range page, quoted below, describes the capacity as adjustable.

No Renault document opened calls that figure installed capacity. The record reads it that way because the June and September releases describe the usable energy as a share of it: “up to 95% of their energy capacity” in June, “up to 95 % of total battery capacity” in September. Renault publishes no usable figure in kilowatt-hours for any version, so the usable-battery row above is blank.

Renault’s UK range page makes a wider statement: that the battery capacity is “fully adjustable, offering configurations from 360 kWh up to 780 kWh”. That page covers the E-Tech T tractors and the E-Tech T rigid together, its tractor row reads “Up to 780kWh” and its rigid row “Up to 540kWh”, and it does not say which configurations can be ordered on which tractor version. In November 2024 Renault also said it encourages customers to “adjust the size of the batteries according to their actual needs”. The June 2026 sheets print one capacity per version; whether a T 540, T 585 or T 780 can be ordered with less than its sheet figure, no document opened says. The rigid is outside this record.

The 660-kilometre range figure

From June 2026 onward Renault gives the T 780 up to 660 km: in the June and September releases, on the UK product page and on the T 780 sheet, where the row is headed “Announced range”. None of them states a load, a test procedure, a temperature or a battery condition. The T 585 and T 540 sheets in the same press kit do state a basis, “500 km at 32T GCW” and “450 km at 32T GCW”. The T 780 sheet beside them does not.

The earlier figure for the same truck had one. In November 2025 Renault gave 600 km for the T 780 and 460 km for the T 585, with a footnote reading “Consumption and range will depend on usage and operating condition. Based on 32T GCW”. The February 2026 results release still gave 600 km for the T 780. By June 2026 the T 780 figure had become 660 km and the T 585 figure 500 km. The June release credits long-haul electrification to improved electric driveline efficiency and a new generation of NCA batteries, and says that extending the batteries’ operating window, so that up to 95% of their energy capacity can be used, increased “the energy effectively available for propulsion”. The September release credits the 660 km to the electric axle, the NCA batteries with their extended operating window and an optimised electric driveline. Neither release says anything about the conditions the figure was measured under. Whether the 660 km rests on the same 32-tonne basis as the 600 km it replaced, no document says.

The 32-tonne basis is two-thirds of the 48 tonnes the same sheets give as the maximum gross combination weight of the 6x2 versions. That fraction is our arithmetic. Renault publishes no range at a heavier weight and no energy consumption figure in any document opened. The difference between a vehicle weight and a combination weight is set out in truck weights, GVW and GCW.

Renault’s July 2026 preview of the fair says the 660 km range enables “a full legal driving day without intermediate charging”; what the law allows in a driving day is set out in driving time and rest rules.

Not every source carries the same figure. Read today, Renault’s corporate electromobility page, the French range page (the dedicated French product page for the three versions now redirects to it) and the German product page all give the T 780 up to 660 km, agreeing with the September and June figures above. The one disagreement left among the live pages is the T 585: the German product page gives it 460 km, while the September release, the June sheet and the French range page all give 500 km. Two dated documents still carry the earlier, superseded figures: the November 2025 release gave 600 km for the T 780 and 460 km for the T 585, and the February 2026 results release repeated 600 km for the T 780. Neither has been revised since.

Charging

CCS charging at 350 kW appears on all three sheets, in the November 2025, June 2026 and September 2026 releases and on the UK range page. It is the only charging figure every document agrees on, but on the T 585 and T 780 it is the lower of two charging systems, so the record above carries no charging figure rather than showing 350 kW as the model’s.

The T 540 is not MCS compatible: its sheet reads “MCS : No” and the UK page footnotes “T540 is not MCS compatible”. For the T 585 and T 780 Renault gives two ratings: 720 kW in the November 2025 release, which says “up to”, and on both June 2026 sheets; up to 700 kW for both on the UK range page. The September 2026 IAA release gives no MCS rating as such. In its fleet-data claim the 45-minute fast charge is made “via CCS (350 kW) or MCS (525 kW for the T 585 / 700 kW for the T 780)”, the only document that gives the two versions different megawatt figures. No document explains why the figures differ. Where the MCS standard itself has got to is set out in megawatt charging explained.

Renault states charging results as kilometres recovered, not as a state-of-charge window. The June 2026 release says E-Tech T vehicles can recover up to 250 km of range in the driver’s mandatory 45-minute break on the 350 kW chargers currently on the market. The November 2025 release said MCS stations could provide the T 585 and T 780 with up to 350 km in a 45-minute break. The UK page says its CCS and MCS figures allow up to 100 km of range “in as little as 15 to 25 minutes, depending on the model”, without saying which charger gives which time. Kilometres recovered depend on consumption, which Renault does not publish.

Motor power

The June 2026 sheets head the row “Peak power” and print 540 kW for all three versions. The horsepower in brackets beside it does not stay the same: 735 hp on the T 585 sheet, 625 hp on the T 780 sheet, and none on the T 540.

Renault’s UK range page gives a different picture. Under “Electric power” it lists the tractors at 300 to 540 kW (405 - 735 hp), and on the next line “420 or 460 kW (570 - 625 hp) Only for T 585 & T 780”. Renault’s French range page carries the same figures. Read as laid out, those pages give the electric-axle versions 420 or 460 kW, not 540 kW. The 625 hp on the T 780 sheet is the top of the horsepower span they give for 420 or 460 kW, while the kilowatt figure beside it on the sheet is 540.

No document opened reconciles the two, says whether the range pages’ figures are peak or continuous, or gives the number of motors on the 2026 versions. The record therefore leaves every motor field blank. The T 540’s 540 kW is not contradicted anywhere. How power figures are defined is set out in reading truck power figures.

Weights, wheelbases and payload

The two 6x2 versions carry a maximum gross combination weight of 48 tonnes on both June 2026 sheets and in the November 2025 table, where the column is headed “Techn. GCW”. That is the weight in the record, and it is tied to those two versions. The T 540 gets no weight in the record, because its documents disagree: 65 tonnes on its June 2026 sheet, 50 tonnes in the November 2025 table. Gross vehicle weight is 19 tonnes for the 4x2 and 26 tonnes for the 6x2 in the November table, and “Tractor 19t to 26t GVW” on the UK page.

Each version has one published wheelbase, and the sheets and the November table agree: 3,600 mm for the T 585, 4,100 mm for the T 780 and 3,950 mm for the T 540. There is no single wheelbase for the model, so that row is blank.

Renault’s payload figures, version by version:

• T 780: up to 27.4 tonnes in the September 2026 release and on its June sheet; 27 tonnes in the text of the June release and, read today, on the French range page too (its dedicated product page now redirects there); 22.5 tonnes on the German product page.
• T 585: up to 28.8 tonnes in the September release and on its June sheet; 28 tonnes in the text of the June release, in the November 2025 release, which adds “in accordance with local regulations”, and, read today, on the French range page too; 24 tonnes on the German product page.
• T 540: 25 tonnes in every document that gives a figure, except the German product page, which gives 23 tonnes.

The June release text and the sheets in its own press kit therefore already differ. The German figures are lower for all three versions, and the page does not say why. On every Renault document that gives both, the T 585 carries more than the T 780.

Battery warranty

The June and September 2026 releases give a standard battery warranty of up to six years or 720,000 km, extendable to 10 years through the Serenity Pack; neither gives a distance for the extension. The UK page repeats the six years or 720,000 km and adds that it is subject to specified operating conditions. The November 2025 release had said something different: that Renault guarantees the performance of the new batteries for up to 8 years or 1 million kilometres, which the web version of that release attaches to a subscription to the Serenity Pack. The web version of the June release notes that the extended coverage was “previously announced as up to 8 years”. The German product page still prints 8 years or 1 million km; the French range page, read today, no longer states the six-year or 720,000 km base term, and instead gives only “a battery coverage that can go up to 10 years under certain conditions” as part of its Serenity Pack description, with no base term and no distance figure, footnoted “contact your dealer for more information”.

Safety and driver-assistance systems

Renault Trucks UK’s range page for the E-Tech T lists a set of driver-assistance systems for the range as a whole, covering the tractor and the rigid together and without separating the list by tractor version. It describes “Driver assist” as providing “continuous steering assistance to maximise comfort and safety by maintaining the vehicle within lane markings while maintaining speed and distance from the vehicle ahead”; “Smart steering” as steering that becomes “more gradual” and “receives more power when necessary” for “improved directional stability”; Line Departure Warning Support with corrective steering (LDWS), which “alerts the driver in case of lane drift and brings the vehicle back within lane markings”; AEBS and AEB Turn (Automatic Emergency Braking System), which “alerts the driver of a possible front or passenger side collision then brakes and stops the vehicle if any action from the driver”; radars and cameras “all around the vehicle” for field of vision and manoeuvring; a rear-view camera giving night and wide-angle views; hill start assist with Autohold, which “automatically controls vehicle hold after pedal release” to prevent the vehicle rolling away; and automatic activation of headlights and windscreen wipers. The page does not mark any of these systems as standard or optional, or say whether they differ between the T 540, T 585 and T 780.

Equipment and options

The same page lists cab equipment for the range, again without separating it by version or marking items standard or optional: keyless entry with a start button; smart direction-indicator management with steering-wheel-mounted controls; a steering column with several adjustment points and foot control, which the page says eases cab access and knee room; a touchscreen display, given as 9 inches, with cameras, navigation and Android Auto and Apple CarPlay compatibility; two USB-C sockets; and an A4-format document storage drawer.
