The Peugeot 308 diesel variant stands out as a refined family hatchback that prioritizes fuel savings, comfort, and sophisticated design without compromising on everyday usability. This model appeals particularly to those tackling long commutes or high-mileage routines, offering low running costs and a plush driving experience that rivals premium competitors.

Engine Performance and Power Delivery

At the heart of the Peugeot 308 diesel lies a capable 1.5-liter BlueHDi unit, typically delivering around 130 horsepower and substantial low-end torque for effortless acceleration. This engine shines in real-world scenarios, pulling strongly from low revs to enable relaxed overtaking and steady cruising.

Unlike thirstier petrol alternatives, the diesel provides consistent power that feels adequate rather than explosive, suiting drivers who value composure over outright speed. In testing, it achieves 0-62mph times in the low nine-second range, prioritizing smoothness over sprinting prowess.

  • Torque advantage: Peak figures around 300Nm arrive early, ensuring responsive in-gear acceleration without frequent downshifts.
  • Refinement levels: Cabin noise remains subdued at highway speeds, though it can grow audible under hard acceleration.
  • Transmission pairing: Paired exclusively with an eight-speed automatic, it shifts seamlessly across Normal, Eco, and Sport modes for tailored dynamics.

Fuel Economy and Running Costs

One of the diesel 308’s strongest suits is its exemplary efficiency, often exceeding 50mpg in mixed driving and dipping to as low as 5 liters per 100km on highways. Official figures boast CO2 emissions under 100g/km in earlier efficient trims, positioning it favorably for company car users and Benefit-in-Kind tax savers.

Driving ConditionAchieved MPGCO2 (g/km)
Urban45-50110-120
Motorway55-60+90-100
Mixed50-5595-105

These numbers undercut many petrol rivals and even some hybrids on long hauls, thanks to lightweight construction using aluminum components and advanced aerodynamics. Maintenance remains affordable, with Peugeot’s diesel tech proven reliable over high mileages.

Driving Dynamics and Ride Comfort

The 308 diesel masters comfort-oriented handling, absorbing road imperfections with a supple suspension setup that evokes classic French hatchback poise. Smaller wheel options enhance this cushioned feel, minimizing harshness over potholes while maintaining stability at speed.

Steering is light and precise for urban maneuvers, aided by a tight turning circle under 11 meters, making parking a breeze. On twisty roads, it trails sportier foes like the Ford Focus due to moderate grip levels and gearbox vagueness, but excels as a serene motorway companion.

Key Driving Pros

  • Exceptional ride compliance for long journeys
  • Maneuverable in tight spaces
  • Low-speed safety aids like automatic emergency braking

Potential Drawbacks

  • Not as engaging as Focus or Golf
  • Steering lacks feedback
  • Occasional rear-end thumps

Interior Quality and Technology Features

Peugeot’s i-Cockpit defines the cabin, with a compact steering wheel and high-set instrument cluster creating an aviation-like ambiance. Materials blend soft-touch plastics, leather accents, and metallic trims for an upmarket vibe that punches above its price class.

The 10-inch touchscreen integrates seamlessly with wireless Apple CarPlay and Android Auto, while climate controls and ambient lighting add luxury. Allure and GT trims elevate this with massaging seats and a panoramic roof option.

  • Infotainment: Responsive interface with sat-nav and voice commands
  • Seating: Supportive fronts; rear space adequate for adults
  • Storage: Generous cubbies and door pockets

Practicality and Boot Space

As a five-door hatchback, the 308 accommodates families with 412 liters of boot capacity expanding to over 1,300 liters with seats folded. The estate SW version boosts this further for those needing extra versatility.

Rear legroom suits children and average adults, complemented by ISOFIX points and wide-opening doors. Fuel tank capacity supports 600+ mile ranges, ideal for road trips.

Safety and Driver Assistance Systems

Earning top ANCAP and Euro NCAP ratings, the diesel 308 packs adaptive cruise control, lane-keeping assist, blind-spot monitoring, and traffic-sign recognition. Low-speed collision avoidance enhances city safety.

Standard across trims, these features provide peace of mind, with robust crash structures from high-strength steel.

Pricing, Trims, and Market Positioning

Starting around €32,000 for base Active diesel, prices climb to €40,000+ for loaded GT models, competitive against VW Golf, Hyundai i30, and Kia Ceed. Leasing deals favor the diesel for its BIK efficiency.
