Borg Warner Turbocharger, Supercharger and Ram Air

BorgWarner: A Century of Powertrain Innovation

BorgWarner stands as one of the most storied names in automotive engineering. Founded in 1928 as a merger of four pioneering automotive suppliers — Borg & Beck, Warner Gear, Marvel-Schebler Carburetor, and Mechanics Universal Joint — the company was built on a foundation of transmission and drivetrain expertise that quickly earned it a place at the heart of the American auto industry. From supplying Ford with transmissions in the 1930s to becoming a global technology leader today, BorgWarner has spent nearly a century pushing the boundaries of what powertrain components can do.

Turbocharging Leadership with Deep Roots

While BorgWarner's legacy spans many powertrain disciplines, it is in turbocharging where the brand has achieved its most iconic status. BorgWarner turbochargers are produced with over 100 years of boosting heritage behind every unit. The brand's Turbo Systems division grew through the integration of world-class turbo producers — including the Schwitzer and 3K (Kühnle, Kopp & Kausch) lineages — bringing together decades of engineering know-how under one roof. The result is a lineup that covers an extraordinary range of applications, from street-performance gasoline engines to heavy-duty diesel trucks and even motorsport.

Among BorgWarner's most celebrated technical achievements is the Variable Turbine Geometry (VTG) system, co-developed with Porsche for use in the 911 Turbo, which dynamically adjusts exhaust flow to eliminate turbo lag. The brand's EFR (Engineered for Racing) and AirWerks performance lines cover power ratings ranging from street-friendly outputs all the way up to four-digit horsepower figures, making BorgWarner a go-to source for both OEM replacement and performance upgrades.

A complete turbo system is more than just the core assembly, and BorgWarner supplies every critical piece. Enthusiasts and technicians can source BorgWarner turbocharger cartridges — the precision CHRA (center housing rotating assembly) — for targeted rebuilds, as well as turbocharger housings that maintain exact OEM geometry for proper fitment and flow. For those chasing peak performance, the BorgWarner turbocharger turbine wheel is a critical rotating component where material quality and dimensional precision directly translate to power and reliability.

Drivetrain Expertise Beyond the Turbo

BorgWarner's powertrain reach extends well beyond forced induction. Through its acquisition of Haldex Traction in 2011, the company brought advanced all-wheel-drive coupling technology into its portfolio. This expertise includes the formulation of BorgWarner differential oil, specifically engineered for use in BorgWarner Haldex AWD systems found in vehicles from Volkswagen, Audi, Land Rover, Volvo, and more. Using the correct, manufacturer-spec fluid in these systems is essential for maintaining friction characteristics and preventing premature wear in the wet clutch pack.
