Overview

The 508 saloon is 4.79 m (189 in) long, while the 508 SW (estate) is 4.81 m (189 in) long.^[5] Compared to the Peugeot 407, the 508 has a shorter front overhang and a longer rear passenger compartment.^[6]

After a few initial leaked spyshots, the first definitive details and images leaked to the web on 12 July 2010.^[7] Peugeot released additional information on 6 September 2010.^[8] The 508 was officially launched at the 2010 Paris Motor Show. PSA Peugeot Citroën build the 508 in China in partnership with Dongfeng Motor. It was launched there on 10 August 2011.^[9]

It was reported in 2011 that Peugeot expected China to be the largest market for the car, at almost twice that of France. If predictions were correct, it would be the first time that the company sold more units in any country other than France for any model that is available in Europe.^[3]

The Peugeot 508 was given a facelift in 2015, with the introduction of a vertical grille with the Peugeot lion in the centre.^[10] The front of the car was redesigned and full LED headlights became available. New engines were also launched, and front-wheel drive introduced for the RXH. The Peugeot 508 has received several international awards including Car of the Year 2011 in Spain (awarded 2012), Next Green Car, and Best Large Family Car 2011.^[11] Citations commented on the car "being spacious and well equipped" and that it "represented excellent build quality and has the best fuel economy in its class" (Peugeot 508 1.6 e HDi 109g CO₂/km) or also Auto Zeitung Best Imported Family Car 2011^[12] (readers' votes).

Technical highlights

Peugeot has equipped the 508 for the market in Europe with its HDI common rail diesel engines. The 1.6-litre HDI 112 can be fitted with the e HDI 'micro hybrid' system, including an electronically controlled automatic gearbox, which reduces fuel consumption to 4.20 L/100 km; 56.0 mpg_‑US (67.2 mpg_‑imp) with CO₂ emissions of 109 g/km.^[13]

Though this matches the Volkswagen Passat Bluemotion, it features a slightly larger fuel tank which allows it to cover a slightly longer range of 1637 kilometres (1017 miles).^[14] At least two e HDI engines were available from 2011 to 2012. The first engines had an emission level of 114 g/km. The later model reduces emissions to 109 g/km. A modified air intake is the main reason for the improvement.

The 508 range also included PSA's HYbrid4 diesel electric hybrid powertrain, which reduced fuel consumption further, to 3.80 L/100 km; 61.9 mpg_‑US (74.3 mpg_‑imp) with CO₂ emissions of 99 g/km.^[15]

The top GT version comes with a 201 bhp (150 kW; 204 PS), 2.2-litre turbodiesel engine which generates 458 N⋅m (338 lbf⋅ft) of torque. It comes mated solely to a six speed torque converter automatic gearbox which offers manual shifts via paddles or a central selector.

From a system which rates to a maximum of five stars, the 508 received a five star rating by Euro NCAP in 2011. The score was:

508 RXH

2012 Peugeot 508 RXH in Düsseldorf, Germany

At the 2011 Frankfurt Motor Show, Peugeot revealed a hybrid-electric crossover estate de luxe variant of the 508. To distinguish it from other 508 models, the RXH features flared wheel arches, as well as a new color-coded grille with three columns of LED daytime running lights on each side.

The Hybrid4 powertrain combines a 120 kW (163hp) 2.0-litre HDi FAP diesel engine with a 27 kW (37hp) electric motor to lower fuel consumption to 4.2 L/100 km. The powertrain offers four working modes:

AUTO, in which the vehicle strives for the best fuel economy, throttle response is slow and the automated manual transmission shifts early, furthermore the vehicle switches to ZEV mode as often as possible.

SPORT mode offers a combined power output of 150kW (200hp) and 450Nm at speeds up to 120km/h, throttle response is very aggressive and the engine revs up to 4000RPM before upshifts.

4WD mode keeps the HDi engine running constantly and charging the high voltage battery to offer constant 4WD at speeds up to 120km/h.

ZEV mode is available if the high voltage battery is at least 1/3 full. In this mode, the vehicle moves only via the rear electric motor and the performance is limited. ZEV mode is available at speeds of up to ~60km/h with moderate acceleration, the range on a full charge is about ~2miles (~3km), the A/C compressor is automatically switched off in this mode. If the driver presses the accelerator beyond a certain point, the HDi engine restarts automatically as to offer better acceleration and the vehicle goes to AUTO mode. Auto Start Stop is available in all modes except for 4WD when the engine is constantly running so that the reversible alternator can top up the battery and provide constant rear drive.

The engine automatically shuts down whenever possible (cruising downhill at speeds of up to 85km/h when the battery is not fully charged or cruising on a level surface at speeds of up to ~60km/h), when coming to a stop the HDi engine shuts down at speeds below 30km/h. Restarting can occur at any moment, if the HYbrid4 control unit determines that additional power is needed; or the battery needs to be topped up; or the A/C compressor needs to kick in.

The engine also restarts when the battery is fully charged and the vehicle is going downhill, as to offer additional engine braking, no fuel is used in this mode, but ZERO EMISSION is not displayed, as the HDi engine is rotating. The battery consist of 42 packs of four D-size SANYO batteries (201.6V nominal, ranging from 168V to 250V during use). To offer a longer battery pack life the HCU (hybrid control unit) never charges the batteries over 90% of their capacity, nor discharges them under 30%.

The 508 RXH HYbrid4 also has raised ground clearance of 184mm - 30mm more than the standard 508 SW and 508 HYbrid4.

The RXH was released in the beginning of 2012.^[17] The 508 RXH was launched in a single high spec limited edition version, before a full range became available. It is competing with the Audi A4 Allroad, the Volvo XC70, the Passat Alltrack or even more, the BMW 3 Series XDrive.

508 coupé by Peugeot

A concept "hybrid power" car prefiguring the style of the future 508 coupé, called the Peugeot SR1, was presented at the Geneva Motor Show in March 2010.^[18]

Sources reported that the Peugeot SR1 would go on sale in 2012.^[19]

508L (China)

The Peugeot 508L premiered at the 2018 Guangzhou Auto Show in China. Compared to the European 508 model, the 508L exclusive to China has a 55 mm (2.2 in) longer wheelbase, making the length of the 508L wheelbase 2,848 mm (112.1 in). The Chinese 508L version is also 100 mm (3.9 in) longer overall than the 508 sold in Europe, at 4,870 mm (192 in).

Another difference between the two versions is in the rear with the five-door liftback configuration of the European 508 being replaced by a conventional trunk, making the 508L a traditional four-door sedan in China. Stylingwise, the frameless doors of the European 508 was replaced with framed ones for the 508L.^[30]

It received a facelift mid-2023.

Driving features

The Peugeot 508 includes various features.

The safety kit includes automatic emergency braking, adaptive cruise control, active blind spot detection including some steering correction to avoid an accident, speed and road sign recognition, automatic headlight beam selection and some driver-attention monitoring systems.

A windscreen camera is used to provide the features such as Active Lane Keeping Assistance and Road Edge Detection, speed sign recognition and Lane Positioning Assist, which can keep the car in the centre of the lane.

The 508's Safety Plus Pack has sensors to watch areas out of the field of vision, to warn the driver by a LED.

The car has also parking aids, ranging from front and rear sensors up to fully automated assistance for both parallel and car park spaces.^[33]

508 PSE

In February 2020, Peugeot unveiled the 508 PSE (Peugeot Sport Engineered), available both in liftback and estate body styles.^[34]

The 508 PSE sales has been way under Peugeot sales target (5 to 6% of the 508 total sales).^[35] As of April 2022, only 2,000 units had been manufactured.^[36] In February 2023, the pre-facelift 508 PSE was discontinued.^[37]
