Automotive Electronics

Magna started in 1957 as a one-man tool-and-die shop in a Toronto garage, founded by Austrian immigrant Frank Stronach. Seven decades later it is the most diversified auto supplier in the world: 179,000 employees across roughly 340 manufacturing plants in 28 countries, with 2023 sales near US$42 billion. Unusual for a parts maker, Magna can build an entire car. Its complete-vehicle assembly unit has produced millions of vehicles for brands including Mercedes-Benz (the G-Class) and BMW, while its component divisions span body exteriors, seating, powertrain, mirrors, lighting, electronics, and mechatronics such as smart door systems. The company is also a major EV supplier, manufacturing battery enclosures, e-drive units, and thermal management systems. Buyers work with Magna for a specific reason: one supplier that can handle a system rather than just a part, with engineering centers near most OEM plants and a launch-quality record that keeps it on virtually every automaker's approved vendor list.

Continental was founded in 1871 in Hanover as a rubber factory — six months after the German Empire was proclaimed — and made its name first with soft rubber products, then bicycle tires, then the studded tire it invented in 1904. More than 150 years later, the company has become something rarer than a tire maker: a tier-one automotive electronics supplier that still sells tires, straddling two very different businesses under one roof. The tire division makes passenger, truck, and specialty tires (including the winter tires where Continental holds a premium reputation), while the automotive division supplies brake systems, air suspension, sensors, displays, and the software that binds them — including the camera and radar systems behind advanced driver assistance. Continental's ContiTech unit adds industrial hoses, conveyor belts, and automotive interior materials. With about 200,000 employees and annual revenue near €41 billion, Continental is in the middle of the industry's biggest transition: it has restructured around 'autonomous mobility, software, and sustainability' while spinning off parts of its automotive business. For vehicle buyers, it offers a rare combination — tires and electronics from one supplier, which is why virtually every global automaker has a Continental contract of some kind.

DENSO's origin is a corporate spin-off with a difference: in 1949, Toyota spun off its electrical parts division into an independent company, and that company — now DENSO — grew into the world's second-largest automotive parts supplier, while remaining one of Toyota's most trusted partners. The Kariya-based firm is the invisible giant behind modern cars: if your vehicle has climate control, a starter motor, an alternator, or an engine ECU, it very likely came from DENSO. The company's product range is the widest in the industry: powertrain systems (fuel injection, spark plugs, turbochargers), thermal systems (air conditioning compressors, radiators, battery cooling for EVs), electrification components (inverters, motors, DC-DC converters), and semiconductors for automotive use, including the sensors that make autonomous driving possible. DENSO also leads in radar and camera-based safety systems. With about 160,000 employees and annual revenue near ¥7 trillion (US$47 billion), DENSO is reinventing itself for the EV era — investing in SiC power semiconductors, thermal management for battery packs, and mobility software. For automakers outside Toyota's orbit, DENSO has become a preferred supplier of electrification components, proving the spin-off has outgrown its parent's shadow.

Infineon's roots run through the entire history of European semiconductors: it began as the semiconductor division of Siemens, was spun off as an independent company in 1999, and is now the world's leading supplier of automotive semiconductors — the chips that manage everything from engine control to airbags to EV power trains. On average, a modern car contains more than a hundred Infineon chips. The company's technical edge is power: Infineon is the global leader in power semiconductors — the devices that switch and convert electrical power — including IGBTs and silicon carbide (SiC) modules that are essential to electric vehicles, solar inverters, wind turbines, and data center power supplies. It also makes the security chips in passports and payment cards, and radar and MEMS sensors for cars and consumer devices. With about 58,000 employees and annual revenue near €16 billion, Infineon has ridden the EV and renewable energy booms to record results, and its new SiC factories in Malaysia and Austria are among the largest power semiconductor investments in Europe. For the auto industry, Infineon is a critical dependency — the kind of supplier whose chips are designed into platforms years before production, and whose capacity constraints can ripple through the entire car market.

In 1886, Robert Bosch opened a 'Workshop for Precision Mechanics and Electrical Engineering' in Stuttgart — and in 1902 his company invented the high-voltage spark plug, the product that made the gasoline engine practical and Bosch's fortune. What makes Bosch genuinely unusual among global industrial giants is ownership: 94% of the company is held by a charitable foundation, meaning no shareholders demand quarterly profits, and the company famously reinvests most of its earnings. The business spans mobility (fuel injection, braking systems, ADAS sensors, and now EV powertrains), industrial technology (hydraulics, packaging machinery), consumer goods (power tools, home appliances under the Bosch and Siemens brands), and energy & building technology. Bosch is the world's largest automotive supplier, and its common-rail diesel and ESP stability systems became industry standards. With about 420,000 employees — making it one of the world's largest private employers — and annual revenue near €92 billion, Bosch is in the middle of its largest transformation ever: restructuring around electrified mobility and software-defined vehicles. Its foundation ownership lets it make decade-long bets that public competitors cannot, a structural advantage that shows in its willingness to keep investing through downturns.
