IAA Transportation 2026 turned concept trucks into a production schedule, with battery electric and hydrogen platforms now carrying fixed build and delivery dates through 2028. Several of those platforms replace the diesel engine, transmission and fuel system that a large share of the European supply base still sells against.
For a supplier whose order book still runs through combustion drivetrains, these dates set the clock on when that revenue has to be replaced.
Volvo Trucks has started series production of the FH Aero Electric in Sweden, offering up to 700 kilometres of range. Daimler Truck plans to put 100 fuel cell trucks into customer use from late 2026. That launch is backed by a mid three-digit million euro investment in hydrogen truck technology. BYD confirmed its ETT 44 heavy electric truck reaches the European market from 2027, with local assembly starting in 2028. Tesla said the Semi enters Europe in 2027 with 550 kilometres of range, competing directly against Daimler Truck, MAN, Scania, Volvo, Iveco and Renault. Toyota will supply the fuel cell system for Iveco’s S-eWay Fuel Cell, rated at 300 kW with a range beyond 900 kilometres. And Mahle has opened range extender projects with truck manufacturers, pairing a small diesel engine and generator to stretch electric truck range.
What changed
At IAA Transportation 2026 in Hannover, truck makers moved past prototypes and put dates on production lines. Volvo has already begun series production, and Daimler Truck has fixed a customer delivery window for hydrogen trucks. BYD and Tesla have set 2027 market entry for Europe, with BYD adding local assembly from 2028.
Toyota and Iveco confirmed a fuel cell supply partnership. Mahle opened its first range extender projects to give existing electric truck platforms extra range without a larger battery or a full hydrogen build. Several large industrial firms also agreed to accelerate the hydrogen truck ramp up, with Germany named as the starting point. More on how these platform shifts move through the supply base sits in the insights library.
What it means for a Tier 2 supplier
A part built only for a diesel engine, gearbox or exhaust system now competes against platforms with confirmed build dates. If a large share of your business runs through those systems, the platforms above show which OEMs are already shifting volume away from them, and when.
A production date is a deadline for the parts that platform no longer needs.
Fuel cell and range extender projects also open a narrower door. Toyota and Iveco need fuel cell balance of plant parts. Mahle needs small diesel generator units built for a duty cycle that has little in common with a full truck engine. Working out which of those openings fit your process, and which platforms to let go, is exactly the kind of decision covered in choosing a diversification adviser.
What to check this month
Map which of your current truck parts sit on a diesel engine, transmission or exhaust system. Check whether the OEM has a battery electric or hydrogen platform announced to replace it before 2028. That answer decides how much of the revenue is already on notice.
Ask whether your tooling and process could serve a fuel cell balance of plant part or a range extender generator. Do not judge that fit only against the diesel part it was originally built for. A tooling line that fits one drivetrain sits one customer decision away from standing idle.
Check how much of your order book with a single OEM sits on a platform without a confirmed electric or hydrogen successor yet. That gap is where the next RFQ conversation still has to happen, and it favours the supplier who raises it first.
How much of your current order book depends on a drivetrain that the OEM has already scheduled to replace?
The diversification brief is a short read that maps where a Tier 1 or Tier 2 supplier’s position stands against these platform shifts. That is the kind of work DreCo does with suppliers before a first conversation is needed.
Frequently asked questions
When will Volvo’s electric truck reach production?
Volvo Trucks started series production of the FH Aero Electric in Sweden in September 2026, offering up to 700 kilometres of range. The fixed body Volvo FH Electric is due to enter the market gradually from early 2027.
How many fuel cell trucks is Daimler Truck putting into customer use?
Daimler Truck plans a small series of 100 fuel cell trucks in customer use from late 2026. That launch is backed by a mid three-digit million euro investment in hydrogen truck technology through the end of the decade.
When does BYD’s electric truck reach Europe?
BYD’s ETT 44 heavy electric truck, fitted with a 651 kWh battery and up to 600 kilometres of range, reaches the European market from 2027. Local assembly in Europe is set to start in 2028.
What is a range extender for an electric truck?
A range extender pairs a small diesel engine, generator and fuel system with an electric truck platform to add range without a larger battery. Mahle has opened its first projects with truck manufacturers to build prototypes using this approach.
