Quick answer: yes - electric trucks tow heavy trailers extremely well on torque, with instant pulling power from zero rpm and full GCW ratings comparable to diesel. The trade-off is range: plan on 60-75% of solo range at full combination weight. Trucks like the TE9L electric heavy-haul tractor use standard fifth-wheel hardware, so existing trailers connect directly.
Yes - and on torque, better than diesel. Electric motors deliver maximum torque from zero rpm, which is precisely what moving a heavy trailer from standstill demands. The TE9L electric heavy-haul tractor pairs a 510 kW LvKong motor with a 600 kWh CATL LFP pack, rated for full heavy-haul combination weights, and drivers notice the difference immediately: no clutch slip, no gear hunting, no turbo lag - just continuous, controlled pull from the first meter. Where diesel tractors downshift and rev on grades, the electric truck holds a steady, quiet pull. Towing is not the electric truck's weakness; in the first fifty meters of every start, it is arguably its strength.
Trailer towing is governed by gross combination weight ratings, and electric tractors carry GCW figures comparable to diesel equivalents - heavy configurations rate for full legal combination weights in their markets. Two checks matter for buyers. First, match the rated GCW to your trailer and payload combination with margin - we configure tractors to the ordered duty, not a generic rating. Second, verify local regulation: several markets grant zero-emission trucks weight allowances of up to two tonnes, recognizing battery mass, which can restore or even improve payload parity. Hitch and fifth-wheel hardware is standard commercial equipment - the TE9L uses conventional couplings, so existing trailers connect without adaptation.
Towing at full combination weight increases energy consumption by 30-60% over solo running - the honest figure diesel experience would predict, since aerodynamic drag and rolling resistance dominate at weight. On a 600 kWh pack with 350 km of certified solo range, prudent planning derates to 60-75% for heavy trailer duty, refined within weeks by telematics data on your actual routes. Two mitigations matter: regenerative braking recovers significant energy on descents and in stop-start running - heavy combinations regenerate impressively - and speed discipline pays double when towing. Fleets in Chile running electric tractors on trailer work plan routes around the derated figure, charge during natural loading and rest windows, and report schedule reliability matching their diesel operations.
Electric tractors tow on standard hardware under standard rules - fifth-wheel couplings, electrical and pneumatic connections, and trailer brake systems identical to diesel practice. Regenerative braking integrates with trailer brakes through the same pneumatic control drivers already know, with the electric system handling the first stage of retardation and friction blending seamlessly behind it - tractor-trailer brake balance is factory-calibrated and workshop-adjustable. Driver training adds one towing-specific habit: anticipating regeneration behavior with a heavy trailer behind, which most drivers master within days. Weight distribution and fifth-wheel positioning follow standard practice. Nothing about the towing interface is exotic - which is exactly the point fleets should want to hear.
Match the tool to the duty cycle. Short and medium-haul trailer work - port drayage, regional distribution, construction supply, agricultural haulage - is electric's sweet spot: routes within the derated range, return-to-base charging, and fuel savings that scale with the daily kilometers trailer work accumulates. Long-haul beyond daily range currently favors planning: corridor charging is expanding, but routes must be mapped honestly. Many fleets in Chile run a mixed transition: electric tractors on the predictable trailer circuits, diesel retained on irregular long-haul, with the diesel count shrinking as corridor charging fills in. At an FOB range of $155,000-$180,000, the TE9L business case strengthens with utilization - and trailer work delivers utilization. See the Chile electric truck market page for regional towing experience.

The financial case for the TE9L rests on arithmetic that favors electric drivetrains at high utilization. Purchase price at an FOB range of $155,000-$180,000 sits above diesel, but energy cost per kilometer falls by 60-75%, scheduled maintenance drops 40-60% with no engine service items, and regenerative braking extends friction brake life two to three times. Insurance and financing terms for electric trucks in Chile now track diesel norms as underwriters accumulate claims data. The residual value side strengthens the case further: the 8-year/4,500-cycle battery warranty transfers to second owners, putting a factory-backed floor under resale prices. On a duty cycle above 150 km per day, most fleets model payback of the price premium inside three years and lifetime savings of $40,000-$90,000 per truck across an eight-year hold. We provide a fleet-specific TCO model with every quotation, using your actual fuel price, tariff and utilization rather than brochure assumptions.
Long-term parts support decides whether an imported truck fleet thrives or stalls. We maintain a structured parts program for the TE9L: a recommended starter stock of high-turnover items - filters, brake components, sensors, contactors, lamps and coolant - sized to fleet count and consigned at delivery; scheduled replenishment by sea for planned maintenance; and air freight dispatch from our Xi'an warehouse for breakdown-critical orders. Every truck ships with a full parts catalog using factory part numbers, so orders are unambiguous. High-voltage components and battery modules move under dangerous-goods-compliant logistics with the documentation customs authorities require. For fleets in Chile, we also advise on which wear items can be sourced locally and which should stay factory-genuine - a distinction that protects warranty coverage while controlling cost. The objective is simple: a truck off the road earns nothing, and our parts pipeline is built to keep downtime measured in days, not months.
Structuring the purchase correctly matters as much as choosing the right truck. Standard export terms for the TE9L run on confirmed irrevocable letter of credit or telegraphic transfer with deposit and balance against shipping documents, and we work with buyers' banks across Chile to make documentation smooth. For fleet-scale orders, staged payment schedules aligned to production and delivery milestones reduce financing cost, and some buyers layer in export credit or leasing structures from their local market. Buyers should also investigate Chilean green financing programs - development banks and national green funds increasingly offer concessional rates for zero-emission commercial vehicles, which can cut the effective interest cost meaningfully below commercial lending. The FOB range of $155,000-$180,000 for the TE9L should be modeled against these financing options alongside the operating savings, because the right funding structure often improves project economics more than a marginal price negotiation. Our export team supports proforma documentation for bank applications at no charge.
Yes. Electric motors deliver maximum torque from zero rpm - ideal for moving heavy trailers from standstill - and heavy electric tractors like the TE9L with a 510 kW motor and 600 kWh battery are rated for full legal gross combination weights.
Expect 25-40% range reduction at full combination weight: a 600 kWh pack with 350 km certified range should be planned at 210-260 km for heavy trailer duty, refined by telematics data on your specific routes within the first weeks.
No. Electric tractors use standard fifth-wheel couplings and conventional pneumatic and electrical trailer connections, so existing trailers connect without adaptation, and regenerative braking integrates with standard trailer brake systems.
Yes - it is calibrated at factory for combination operation. Regeneration handles the first braking stage and friction brakes blend behind it, with tractor-trailer balance workshop-adjustable; heavy combinations actually regenerate more energy on descents.
On high-utilization trailer duty, yes: energy cost per kilometer falls 60-75% and maintenance 40-60%, and at FOB prices of $155,000-$180,000 for a heavy electric tractor, fleets running daily trailer circuits typically recover the premium in about three years.
