The Peugeot 308 III, launched in 2021 (Phase I), represents the third generation of Peugeot’s popular compact hatchback. Positioned as a competitor to vehicles like the Volkswagen Golf, Ford Focus, and Opel Astra, the 308 aims to blend stylish design with efficient technology. This generation marked a significant departure from its predecessors, featuring a completely redesigned interior and exterior, and a greater emphasis on digitalization. The 1.5 BlueHDi (130 Hp) EAT8 variant, detailed here, was a key offering in European markets, focusing on fuel economy and reduced emissions with its modern diesel powertrain.
Peugeot 308 III: A Detailed Overview
The 308 III is a five-door hatchback designed to appeal to buyers seeking a practical yet sophisticated vehicle. While not officially sold in the United States, the 308 is a mainstay in the European C-segment, known for its comfortable ride, refined interior, and competitive pricing. The Phase I models, produced from September 2021 to August 2025, established the foundation for the third-generation 308, setting the stage for subsequent updates and powertrain options.
Engine & Performance
The 1.5 BlueHDi variant of the 308 III is powered by a 1.5-liter inline-four cylinder diesel engine, designated YHZ DV5RC. This engine produces 130 horsepower at 3750 rpm and 300 Nm (221.27 lb.-ft.) of torque at 1750 rpm. The engine benefits from a turbocharger and intercooler, enhancing both power and efficiency. Power per liter is rated at 86.7 hp/l. The engine is transversely mounted at the front of the vehicle and is paired with an eight-speed automatic transmission (EAT8), contributing to smooth gear changes and optimized fuel consumption. The weight-to-power ratio is 10.5 kg/Hp, and 95.5 Hp/tonne, while the weight-to-torque ratio is 4.5 kg/Nm, or 220.4 Nm/tonne. The inclusion of a Start & Stop system and a particulate filter underscores Peugeot’s commitment to reducing emissions, meeting the stringent Euro 6.3 emission standards.
Design & Features
The 308 III boasts a modern and aerodynamic design, characterized by a sharp front end with Peugeot’s signature LED daytime running lights. The hatchback body style provides a practical balance between passenger space and cargo capacity. Inside, the 308 III features a completely redesigned i-Cockpit interior, a hallmark of modern Peugeot vehicles. This includes a compact steering wheel, a raised instrument panel, and a large central touchscreen display. The interior prioritizes a minimalist aesthetic with high-quality materials. Safety features are comprehensive, including ABS (Anti-lock braking system) and a robust suite of driver-assistance systems. Trunk space is a practical 412 liters (14.55 cu. ft.) with the rear seats up, expanding to 1323 liters (46.72 cu. ft.) when folded down. The vehicle comfortably seats five passengers.
