Peugeot 508 plug-in hybrid specs, performance and range

Like the look of the sharp new Peugeot 508 but don't want a standard petrol or diesel? You're in luck: plug-in hybrids are now available

Peugeot has let its electrification engineers loose on the 508 range, with plug-in hybrid (PHEV) versions of the 508 fastback and estate due in the UK next year. Order books are set to open before the end of 2019 but prices are yet to be confirmed.

The motoring industry is becoming more and more hybrid-heavy and the Peugeot range is no exception. Along with launching hybrid 508 models, the French carmaker has recently revealed a plug-in version of its 3008 SUV plus all-electric versions of the new 208 hatchback and 2008 crossover are on the way too.

Quick facts

  • Around 30 miles of all-electric range
  • Claimed CO2 emissions of 29-36g/km
  • Full charge in as little as two hours
  • Hybrid4 models with 225hp
  • Saloon and estate models available
  • Orders open before the end of 2019

Peugeot had let its rivals take the upper hand in the family saloon/estate market. Cars like the Volkswagen Passat and Ford Mondeo are commonplace on UK roads, while the old 508 (which many won’t even realise existed) is a rare sight indeed. If you do spot one, you will notice they are anything but exciting to look at.

The new 508 is something of a contrast. It's striking both inside and out and, thanks to the addition of frugal, low-emission hybrid models, they should appeal to everyone from family buyers to company car drivers. Read on to find out more about the new Peugeot 508 plug-in hybrids' prices, performance, interior and more.


Peugeot 508 plug-in hybrid specs

Both the 508 'fastback' and estate (named the SW for 'station wagon') will come with a choice of three trim levels: Allure, GT Line and GT. If you are unfamiliar with Peugeot’s model hierarchy, Allure represents the entry-level, GT Line sits in the middle, and GT stands tall at the top.

As for the fastback, a 'fastback' is a hatchback or saloon with a rear-end that slopes from the top of the roof pretty much all the way down to the rear bumper giving it a coupe-like appearance, while a station wagon is another way of saying estate - it's long and roomy.

Standard equipment for the hybrid models is yet to be confirmed, but Allure spec petrol and diesel models include Bluetooth, dual-zone climate control, sat-nav, digital radio, a 10-inch touchscreen media system (which is Android Auto and Apple CarPlay compatible), rear parking sensors and 17-inch alloy wheels.

GT Line models bring sporty looks without the high running costs you might associate with performance oriented cars. On top of the standard kit for entry-level PHEV models, drivers will likely get full LED headlights, black roof lining, aluminium pedals, checkered front grille, gloss black rear bumper diffuser and 18-inch alloy wheels.

At the top of the range are GT models which are expected to come with equipment such as an electric boot opening and closing, electric front seats (which also have massaging functions), an uprated sound system and 19-inch alloy wheels.

Peugeot has confirmed that all hybrid 508s will come with four driving modes. First up is Zero Emission mode, which, you guessed it, means the 508 drives under battery power alone - provided the car has enough charge. Then there is Sport mode, which gears the hybrid powertrain for maximum performance and Hybrid mode, which switches between petrol and battery power for optimised efficiency. The final option is Comfort, which softens the suspension for improved ride comfort.

Peugeot 508 plug-in hybrid prices

Peugeot is set to open order books for 508 fastback and estate plug-in hybrids before 2019 is finished. Delivery dates are yet to be confirmed, but as the rest of the 508 range is already on sale, deliveries are likely to start in the first half of 2020.

As for prices, Peugeot is yet to release any official information but petrol and diesel 508 Allure, GT Line and GT models start at roughly £27,000, £29,000 and £37,000 respectively. Buyers should expect a substantial hike in the price for having hybrid power, however, so expect to be paying over £30,000 for starters.

Peugeot 508 plug-in hybrid rivals

Hybrid saloons and estates are becoming increasingly popular – partly driven by the fact hybrids are favourable with company car buyers due to the low emissions - and consequently the low tax bills. Fortunately for Peugeot, many of those that are currently available are significantly more expensive than the 508 is expected to be. As an example, the Mercedes E-Class saloon plug-in hybrid starts at nearly £47,000.

The only direct rival for the Peugeot 508 plug-in is the Passat GTE PHEV, which starts at around £38,000 for an estate and £36,000 for a saloon.

Peugeot 508 plug-in hybrid performance

Both fastback and station wagon variants of the 508 PHEV come with the same hybrid tech. This is a combination of a 1.6-litre petrol engine and an electric motor – together they produce 225hp.

Peugeot is yet to confirm torque - that's low engine speed muscle - figures but as for economy there will be no difference between the body styles, with both claimed to be capable of 217mpg under that latest WLTP emissions test procedure.

Carbon dioxide (CO2) emissions are where things differ (slightly). Depending on spec, fastback models will emit between 29g/km and 34g/km of CO2, meanwhile, estate models emit between 30g/km 36g/km of CO2.

Peugeot 508 plug-in hybrid electric range

A fully charged plug-in 508 saloon is claimed to be capable of around 30 miles of all-electric driving. It is worth noting that similar to the emission figures above, the car's electric range is affected by the equipment buyers specify.

Estates suffer a marginal disadvantage in all-electric range on paper but roughly speaking drivers should again expect around 30 miles of zero-emission motoring. Both saloon and estate models use an 11.8kWh (kilowatt-hour) battery pack, which Peugeot claims can be fully charged from empty in under two hours using a 7kW power supply - a common format for charge points installed at motorists’ homes.

Peugeot 508 plug-in hybrid interior

If you have seen the interior of a standard 508 you have seen the interior of a hybrid 508. Key to the modern design is a dashboard which curves around the driver, a central touchscreen media system, driver’s digital dash display and a minimal amount of buttons.

Peugeot 508 plug-in hybrid safety

Currently, all Peugeot 508s get automatic emergency braking, lane keeping assist and an active bonnet (a system which aims to protect pedestrians in the event of a crash, by popping up the bonnet to cushion the impact) as standard.

Petrol and diesel Allure, GT Line and GT models also benefit from driver alertness warning and blind spot monitoring for added safety credentials. It is expected that the PHEV models will also come equipped with the same technology.

For fans of action films (and also pedestrian/animal safety), Peugeot is including night vision technology. This system uses infrared cameras to highlight animals and pedestrians up to 200m in front to help drivers to safely avoid them.

Peugeot 508 plug-in hybrid technology

Being a PHEV, the most impressive technology is arguably hidden under the bodywork, but that is not to say there is nothing else to look forward to. Peugeot’s 'i-Cockpit' layout takes centre stage, with the 10-inch touchscreen media unit and 12.3-inch digital dash display - which you look at over the top of the tiny steering wheel - being two of the most stand out elements.

On top of this is Peugeot’s MyPeugeot app. This, like many similar platforms offered by other carmakers, allows motorists to access key information about their car on a smartphone. MyPeugeot will also send you information (such as fuel consumption) after every trip, so you can keep on top of your motoring costs.

Peugeot 508 plug-in hybrid dimensions

Dimensions for plug-in versions of the 508 fastback and 508 SW are not expected to differ from the conventionally powered models. This means 508 fastbackss measure in at 4,750mm long, 1,859mm wide (including door mirrors) and 1,403mm high. Similarly, estates are 4,778mm long, 1,859mm wide and 1,420mm high.

What is quite impressive is that Peugeot is claiming the new 508 PHEV has the same luggage capacity as non-hybrid models. This means the 508 fastback boasts 487 litres of space, while estates come with 530 litres with the rear seats in place.

For those who are looking for a tow car, Peugeot is yet to confirm official figures for the PHEV 508’s towing capacity.
