Undefined Peugeot 308 Engine Guide: Power, Specs, Options

The Peugeot 308 stands out in the compact hatchback segment with a versatile lineup of engines designed to balance everyday usability, performance, and modern efficiency demands. From mild hybrid petrol units to plug-in hybrids and fully electric variants, the 308 caters to diverse driving needs, whether for city commutes, long motorway runs, or spirited drives. This guide breaks down each powertrain, highlighting key specifications, real-world performance, and suitability for different drivers.

Overview of Powertrain Choices

Peugeot has evolved the 308’s engine range to embrace electrification while retaining traditional petrol and diesel options. The current lineup includes a **1.2-litre mild hybrid petrol**, **1.5-litre diesel**, **plug-in hybrids** in multiple outputs, and the **e-308 electric** model. These options reflect a shift toward lower emissions and better fuel economy without sacrificing the car’s agile handling.

Entry-level models prioritize affordability and economy, while higher trims offer boosted power for quicker acceleration. All engines pair with either manual or automatic transmissions, with automatics dominating the hybrid variants for smoother operation.

Mild Hybrid Petrol: The Everyday Efficient Choice

At the heart of the 308’s accessible range is the **1.2-litre PureTech mild hybrid petrol engine**, producing 143bhp combined from a petrol unit augmented by a small electric motor. This setup replaces earlier non-hybrid versions, delivering improved low-end torque and real-world efficiency around 50mpg.

The six-speed automatic transmission enhances responsiveness, achieving 0-62mph in 8.8 seconds—noticeably quicker than the previous pure-petrol equivalent. Drivers appreciate its refinement, with the electric boost smoothing urban stop-start traffic and enabling brief electric-only cruising.

• Power: 143bhp total
• Torque: Enhanced low-down delivery from 1,500rpm
• 0-62mph: 8.8 seconds
• Top Speed: Around 130mph
• Fuel Economy: Up to 50mpg real-world

This engine suits budget-conscious families or company car users seeking low running costs without the complexity of full hybrids.

Diesel Engines: Torque and Long-Haul Economy

For high-mileage drivers, the **1.5-litre BlueHDi diesel** remains a staple, available in 99bhp and 128bhp tunes. Introduced to replace the older 1.6-litre, it incorporates Selective Catalytic Reduction (SCR) for cleaner emissions and pairs standard with a six-speed manual or optional automatic.

The 99bhp version offers flexible gearing for relaxed motorway cruising, while the 128bhp variant provides ample pull without excessive noise. Real-world figures approach 60mpg on extended journeys, though diesel particulate filter (DPF) maintenance requires regular high-speed runs. AdBlue top-ups are necessary for emission control.

Though less popular amid diesel’s declining favor, these engines excel in refinement and torque for towing or fleet use.

Plug-In Hybrids: Power and Zero-Emission Flexibility

Peugeot’s plug-in hybrid (PHEV) options elevate the 308’s appeal for eco-conscious drivers. The **Hybrid 180** (177bhp combined) and **Hybrid 225** (221bhp) blend a 1.6-litre petrol engine with an 81kW electric motor and 12.4kWh battery, offering 30-40 miles of electric range.

The Hybrid 180 hits 0-62mph in under 8 seconds, with seamless transitions between power sources. The punchier 225 variant accelerates even brisker, ideal for overtaking. Both use an eight-speed automatic, prioritizing comfort on long trips where the petrol engine takes over quietly.

• Electric Range: Up to 40 miles (WLTP)
• Total Power: 177-221bhp
• 0-62mph: 7.5-8s
• Benefits: Tax incentives, low running costs when charged

These are top picks for business users leveraging company car tax breaks.

Fully Electric e-308: Silent and Smooth Urban Star

The **e-308** brings zero-tailpipe emissions with a 54kWh battery powering a 156hp electric motor. It delivers instant torque for brisk off-the-line feel, reaching 0-62mph in about 9.5 seconds—competitive yet not the quickest in its class.

Quoted range hits 267 miles (WLTP), with real-world figures around 200-250 miles depending on conditions. Charging takes 7.4 hours on a home wallbox, and its quiet cabin enhances the premium feel over petrol rivals like the MG4.

Performance is adequate for most, with regenerative braking aiding efficiency in traffic.

Performance Across the Range

No 308 is outright slow; even the diesel manages traffic effortlessly with low-end torque. Petrol mild hybrids feel zingy under 10 seconds to 62mph, while PHEVs and e-308 add EV smoothness. Top speeds hover 118-155mph, sufficient for European limits.

Handling complements engines: light steering and composed ride suit all powertrains.

Fuel Economy and Running Costs Breakdown

Hybrids shine for mixed driving; diesels for pure economy.

Transmission and Driving Dynamics

Manuals offer engagement in base models; e-EAT8 automatics in hybrids provide shift-free cruising. All deliver refined, quiet progress, with minimal engine noise intruding.
