Peugeot/BMW 1.6 Turbo N14 engine

Overview

The BMW N14 1.6L Turbo engine is a compact, high-efficiency petrol powerplant developed in collaboration between BMW and PSA Peugeot Citroën. Designed with advanced turbocharging and fuel injection technologies, this four-cylinder engine delivers strong performance and impressive fuel economy from a relatively small displacement. The N14 balances everyday usability with dynamic power delivery, making it a practical choice for drivers who seek refined performance without compromising on efficiency. Though more commonly found in PSA platforms, the engine carries BMW’s engineering principles and plays a vital role in certain European market applications under the joint development program.

Key Features

1.6L Turbocharged Inline-Four Petrol Engine – The N14 features a 1.6-liter displacement with turbocharging, allowing it to produce a high power-to-displacement ratio. The result is strong, responsive performance that suits both urban and highway driving.

DOHC with VANOS Variable Valve Timing – This engine is equipped with a Double Overhead Camshaft design and BMW’s VANOS system, which actively adjusts valve timing to optimize power output, reduce emissions, and improve fuel economy across various engine speeds.

High-Pressure Direct Injection – Direct fuel injection enhances combustion precision, delivering improved engine efficiency and reduced fuel consumption. It also contributes to the engine’s strong torque delivery and lower emissions.

Twin-Scroll Turbo Technology – The N14’s integrated turbocharger uses a twin-scroll design for faster response and more efficient boost delivery. This setup reduces turbo lag and provides linear power throughout the rev range.

Aluminum Block and Cylinder Head – The engine’s lightweight aluminum construction improves vehicle dynamics by reducing overall weight while maintaining strength and durability. This aids both performance and efficiency.

Performance & Applications

While primarily featured in PSA group vehicles, the N14 engine reflects BMW’s engineering and technical input and forms the basis for performance across several platforms.

Peugeot 207 GT, GTi, and RC (2006–2012) – The N14 powers the sportier variants of the Peugeot 207 lineup, where it delivers strong, turbocharged performance in a lightweight chassis. These models offer agile handling and brisk acceleration, especially suited to urban and backroad driving.

Peugeot 308 THP (2007–2013) – In the Peugeot 308, the N14 engine serves as the heart of the THP (Turbo High Pressure) petrol models. Its combination of torque-rich performance and fuel efficiency makes it ideal for drivers who want both practicality and engaging performance in a compact hatchback.

Peugeot 3008 and 5008 (First Generation, THP variants) – The N14 engine is also available in select THP versions of the Peugeot 3008 and 5008 crossovers. In these applications, the engine provides enough power for family and utility use, while maintaining strong efficiency for longer journeys.
