Peugeot 508 RXH Review: 2012-2018 Hybrid Estate Guide

The Peugeot 508 RXH stands out as a trailblazing vehicle in the world of hybrid estates, merging the torque of a diesel engine with the smoothness of electric propulsion. Launched around 2012, this model targets drivers who demand versatility, low running costs, and a touch of adventure without sacrificing refinement. With its elevated stance and rugged cladding, it positions itself as a stylish alternative to traditional SUVs, delivering official figures of 68.9 mpg combined and just 107 g/km CO2 emissions. This review delves into its design, powertrain, driving dynamics, and everyday practicality, drawing from extensive road tests and expert insights.

Distinctive Exterior Design and Build

The 508 RXH draws its roots from the standard 508 SW estate but elevates it with purposeful off-road aesthetics. It features a 30-50mm increase in ground clearance, depending on the source, paired with protective plastic cladding along the sills, wheel arches, and lower bodywork. This gives it a more assertive presence, reminiscent of premium raised estates like the Audi A4 Allroad or VW Passat Alltrack, yet with a uniquely French flair through its bold grille and claw-like daytime running lights.

Measuring up as a large family hauler, the RXH’s 18-inch alloys and wider track enhance stability, while its sleeker profile compared to boxier rivals like the Peugeot 3008 Hybrid4 avoids a bulky feel. Weighing in at around 1910 kg, the added hybrid components contribute to its substantial mass, but the design cleverly disguises it with smooth lines and a panoramic roof option that amplifies interior spaciousness.

• Raised ride height: Improves approach angles for light off-road use.
• Cladding and alloys: Rugged yet elegant styling cues.
• Dimensions: Generous length for family practicality.

Advanced Diesel-Electric Powertrain

At the heart of the 508 RXH is Peugeot’s HYbrid4 technology, a parallel hybrid system first seen in models like the 3008 and Citroën DS5. It pairs a 2.0-liter turbodiesel engine producing 163 bhp (some tests note 161 bhp) with a 37 bhp rear-mounted electric motor, yielding a combined 200 bhp and 500 Nm of torque. The diesel drives the front wheels via a six-speed automated manual gearbox, while the electric motor powers the rear, enabling on-demand four-wheel drive.

This setup allows for four selectable modes via a console dial, optimizing performance for various scenarios:

• ZEV (Zero Emission Vehicle): Pure electric mode up to 40 mph for 2.5 miles, requiring at least 50% battery charge.
• Auto: Intelligent blending of power sources for maximum efficiency, often yielding impressive real-world mpg in gentle driving.
• Sport: Sharper throttle response and higher revs, achieving 0-62 mph in 8.8-9.5 seconds.
• 4WD: Engages both motors for traction in snow or rough terrain.

The gearbox, though not as seamless as a dual-clutch unit, uses electric torque fill to smooth shifts, prioritizing efficiency over outright pace. Official economy shines at 68.9 mpg, but testers report 47-56.5 mpg in mixed conditions, dropping under enthusiastic driving.

Luxurious and Spacious Interior

Step inside the 508 RXH, and you’re greeted by a premium cabin that punches above its price point. High-quality soft-touch plastics, Nappa leather/Alcantara upholstery, and glossy black trim create a classy ambiance, enhanced by LED ambient lighting. Electrically adjustable, heated front seats offer excellent support for long journeys, with ample rear legroom for four adults.

The dashboard integrates a color head-up display, adjustable for key info like speed and navigation, alongside a central screen for controls and hybrid status. Between the analog gauges, a digital readout provides power flow, battery charge, and economy stats. The nearly full-length panoramic roof floods the space with light, making it feel airy despite the car’s size. Boot capacity remains practical at 423 liters with seats up, expanding further when folded.

• Seating: Supportive and comfortable for extended drives.
• Tech: Head-up display and hybrid monitors.
• Storage: Versatile boot for family needs.

Driving Experience: Balance of Efficiency and Capability

On the road, the 508 RXH impresses with precise, progressive steering that belies its 1.9-tonne weight, making it easy to place through corners. It grips well and resists understeer, though the ride can feel lumpy over small bumps due to the firm suspension tuned for handling. The elevated stance aids light off-road duties or snowy conditions via 4WD mode, but it’s no hardcore SUV.

In Auto mode, efficiency is prioritized, with gentle ambling yielding strong mpg figures—testers noted 56.5 mpg in traffic. Sport mode livens things up, though acceleration feels more urgent than explosive, suiting relaxed motorway cruises (50-70 mph in 6.6 seconds). Real-world tests over 400 miles averaged 47 mpg across town, motorway, and traffic. The system’s frugality shines for company car users, with low BIK ratings from 107 g/km emissions.

Drawbacks include the gearbox’s occasional hesitancy and weight-induced sluggishness under hard acceleration, but overall, it delivers a composed, refined drive with Peugeot’s traditional fluidity.

Practicality for Families and Fleets

Beyond performance, the RXH excels in versatility. Its 4WD capability handles British winters effectively, while ZEV mode suits urban zero-emission zones. Spacious enough for five, with ISOFIX points and a flat-folding load area, it’s ideal for holidays or gear-hauling.

For fleets, the hybrid’s low emissions and high mpg reduce costs, though higher upfront pricing (around £33,000-£36,000 in 2012) demands long-term ownership. Servicing focuses on diesel reliability, with battery warranties covering the electric side. Used examples from 2012-2018 remain appealing for value.
