Cash engines fund a risky power shift
- BorgWarner is still mostly an auto supplier, with light vehicles making up 82 percent of 2025 sales.
- Its older Turbos & Thermal Technologies and Drivetrain & Morse Systems units remain the cash base.
- The battery business is creating a 170 basis point headwind to total sales growth.
- PowerDrive Systems grew Q1 2026 sales 4.6 percent, but still lost $36 million on an adjusted operating basis.
- The new data center plan includes turbine generators that met CARB emissions standards.
A real pivot, still unproven
BorgWarner is trying to do two hard things at once. It is milking its profitable combustion and drivetrain businesses while building EV parts and a new industrial power business for data centers.
The bull case got stronger in mid-2026. Management added Battery Energy Storage Systems and bidirectional microgrid inverters to the data center plan, and the turbine generator achieved CARB-level emission standards. The idea is simple: offer power generation, storage, and conversion to customers that need more reliable electricity.
The bear case is still very live. Total eProducts revenue fell year over year in Q1 2026, and the battery segment is creating a 170 basis point headwind to overall sales due to weak European demand. The industrial products sound promising and are getting $10 million to $15 million in extra research funding, but they are not yet a proven revenue stream.
This makes BorgWarner a balanced story, not a clean growth story. The old business funds the future. The question is whether the new businesses earn enough before auto cycle pressure and pricing pressure eat into that cash.
OEM cash pays for the next bet
BorgWarner is a Tier 1 supplier, which means it sells major parts directly to vehicle makers. Its customers are mostly original equipment manufacturers, or OEMs, that build cars and trucks.
For 2025, light vehicles were 82 percent of sales, commercial vehicles were 10 percent, off-highway vehicles were 5 percent, and the aftermarket was 3 percent. That mix gives BorgWarner scale, but it also ties the company to vehicle production, customer schedules, and hard price talks with large automakers.
The core plan is to use cash from Foundational products, such as turbo, thermal, drivetrain, and timing systems, to fund eProducts and industrial power systems. Management also wants to return capital to shareholders, shown by the 55 percent dividend increase and the $1 billion buyback authorization announced in 2025.
The break point is margin. If EV parts grow but stay loss-making, or if data center products fail to win customers, the company is left relying on slower auto markets and older products for cash.
Combustion cash, EV losses, data center options
Turbos & Thermal Technologies
This is one of BorgWarner's largest Foundational units. Q1 2026 sales were $1.43 billion, down 1.5 percent from the prior year.
Drivetrain & Morse Systems
This unit sells drivetrain and timing-related systems. Q1 2026 sales were $1.42 billion, up 4.5 percent, and the internal view calls it the most profitable Foundational segment.
PowerDrive Systems
This is the key EV and hybrid power electronics unit. Q1 2026 sales rose 4.6 percent to $0.59 billion, but adjusted operating income was negative $36 million.
Battery Energy Systems
This segment was renamed from Battery & Charging Systems after BorgWarner exited charging. Management warned it is creating a 170 basis point headwind to total sales.
Turbine generator systems
BorgWarner plans to supply modular turbine generator systems for data centers. The system has achieved CARB-level emission standards and production should ramp in 2027.
Battery Energy Storage Systems
The company is adapting commercial vehicle battery pack technology for stationary storage. Management expects the product to be production-ready in 2027.
Bidirectional microgrid inverters
These devices convert power for microgrids and grid-tie uses. The portfolio now spans 400 volts to 1,500 volts, with production readiness expected in 2027.
Q1 2026 sales mix
Segment shares use net sales for the three months ended March 31, 2026. The mix is still dominated by Foundational auto units, while eProducts were 17 percent of total sales in Q1 2026.
What could break the story
EV transition stays unprofitable
High impact · Medium oddsPowerDrive Systems is growing, but it still posted a $36 million adjusted operating loss in Q1 2026. If eProducts do not turn profitable, the EV story becomes a drag instead of a growth engine.
Battery segment drags on sales
High impact · High oddsWeak European demand and a lack of North American incentives have hit the battery business hard. Management expects this to create a 170 basis point headwind to year-over-year sales growth.
Data center products miss customer proof
Medium impact · Medium oddsThe industrial plan is promising, but it is still early. The turbine generator, Battery Energy Storage Systems, and microgrid inverters are all aimed at 2027 production readiness or ramp. Until customer contracts and revenue show up, this remains an option, not a proven business.
OEM pricing pressure hits margins
High impact · High oddsBorgWarner depends on large vehicle makers that push suppliers to lower prices. Pricing pressure was previously tied to losses in PowerDrive Systems. If customers demand lower prices while launch costs stay high, margins can weaken fast.
In one breath
What does BorgWarner actually sell?
BorgWarner sells auto parts and systems to vehicle makers. Its lineup includes turbo, thermal, drivetrain, EV power, battery, and charging-related systems, plus newer data center power products.
Is BorgWarner an EV company?
Not fully. BorgWarner is still mostly an auto supplier with a large Foundational business, but eProducts were 17 percent of total sales in Q1 2026.
Why is BorgWarner moving into data centers?
Data centers need more power, backup power, and power conversion. BorgWarner wants to use its automotive engineering and manufacturing base to sell turbine generators, battery storage, and microgrid inverters into that market.
What is the main thing to watch next?
The biggest near-term proof point is whether PowerDrive Systems can turn profitable. The second is whether BorgWarner signs visible customers for its new industrial power products.
