Who makes INFINITI engines?

[EliasRose]

INFINITI engines are primarily manufactured by its parent company, Nissan Motor Corporation. Over 90% of INFINITI's powertrains, including the iconic VQ series V6, are developed and produced by Nissan. For certain past models, engines were sourced from Mercedes-Benz due to a strategic alliance. Today, Nissan and its alliance partners remain the definitive source, with high-performance variants developed by Nissan's motorsport division, NISMO.

The core of INFINITI's engineering identity comes from Nissan. The Renault-Nissan-Mitsubishi Alliance’s global powertrain network is responsible for designing, engineering, and manufacturing the vast majority of engines found under INFINITI hoods. This shared technology strategy allows for economies of scale while enabling INFINITI-specific tuning for higher output and refinement.

The most famous example is the VQ series V6 engine, a staple for decades. Produced by Nissan at its Iwaki and Decherd plants, this engine was exclusively modified for INFINITI applications, earning numerous "Ward's 10 Best Engines" awards. The lineage continues with the VR series 3.0-liter twin-turbo V6 (used in models like the Q50 Red Sport 400), which is also a Nissan-sourced powertrain.

A notable exception was the 2017-2019 INFINITI QX30 and its predecessor, the Q30. These compact crossovers were a direct result of the Daimler-Nissan partnership and utilized Mercedes-Benz M270 and M274 engine families, built in Germany. This partnership has since concluded, and no current INFINITI models use Mercedes-Benz engines.

For performance enthusiasts, the connection to Nissan's NISMO (Nissan Motorsport International) division is key. NISMO engineers are integral in developing high-performance variants, such as the 400+ horsepower VR30DDTT engine. Their expertise in tuning, cooling, and durability directly enhances INFINITI's sportiest offerings.

Looking forward, INFINITI's electrification strategy, including its upcoming variable-compression turbo engines and e-POWER hybrid systems, is wholly dependent on technology and production from Nissan and the broader alliance. This ensures future powertrains will maintain the Nissan manufacturing foundation.

As someone who’s owned two Infinitis, I can tell you the heart of the car is pure Nissan, and that’s a good thing. My old G35 had that legendary VQ V6. It was bulletproof and sounded amazing. When I popped the hood, it said "Nissan" right on the engine cover. My mechanic always said it shared most parts with the 350Z, which made maintenance straightforward and affordable. For a buyer, this Nissan backbone means proven reliability and a huge network of dealers and parts suppliers, which you don’t always get with a pure luxury brand.

Working as a technician at an Infiniti dealership for eight years gave me a clear, hands-on view. Practically every engine we serviced was a Nissan design. The parts system was overwhelmingly shared with Nissan. A catalytic converter for a Q50? Often the same part number as a Nissan model. This commonality is a major advantage for owners in terms of long-term serviceability and cost. The only outliers were the earlier QX30s with the Mercedes engine. Those required different tools, fluids, and diagnostic procedures. While fine engines, they felt like visitors in our service bays. The shift back to a unified Nissan/Infiniti powertrain lineup has streamlined everything from technician training to our parts inventory.
