It also features a top-of-the-range hi-fi system designed by Focal, the latest generation Peugeot i-Cockpit and the latest-generation driving aids to meet EuroNCAP standards.
Set to be revealed at the 2018 Paris Motor Show, the 508 SW has frameless doors - a unique estate car feature for a mainstream carmaker, full LED headlights and opalescent LED daytime running lights.
In the cabin, there are ergonomic, wrap-around seats offering five multi-point massage programmes, a range of premium and sophisticated trim and upholstery materials and a panoramic opening glass roof.
With the aid of the Magic Flat function, allowing the driver to fold back the two sides of the rear bench seat, the all-new Peugeot 508 SW is never short of space, boasting a total load space capacity of 1,780 litres.
Of this total volume, 530 litres comes from the boot (with luggage cover closed), designed to be simple in shape and entirely practical, with hands-free, powered tailgate.
Pierre-Paul Mattei, Peugeot 508 product design director, said: “We wanted to design a unique SW with a very strong personality that was perfectly situated at the heart of its segment. The secret of the rear structure performance in terms of compactness and rigidity is the sensible and practical boot with an extremely sleek design. Similarly, the frameless doors provide the perfect response to accessibility in a vehicle with a very low roof line.”
With 10 loud-speakers fitted with exclusive Focal technology, this hi-fi system provides pure, fine sound.
New features for the range include Adaptive Cruise Control with Stop & Go function, Lane Keeping Assist and a Night Vision system - a first for the segment.
This system utilises an infra-red camera to detect living beings in front of the vehicle at night time or in low-visibility conditions to maximise safety.
The all-new Peugeot 508 SW is built on the EMP2 platform making it an average of 70kg lighter than the outgoing generation while the new eight-speed EAT8 automatic transmission with electric gear lever and one touch control is an option.
Meanwhile, there are two new petrol engine options based on the PureTech 1.6-litre engine.
Also, there are four diesel options are based on the BlueHDi 1.5-litre and 2.0-litre.
In ECO mode, when twinned with the EAT8 gearbox, the PureTech engine automatically switches to freewheeling mode.
This function, available between 25km/h and 130km/h, eases internal friction in the gearbox and reduces fuel consumption by around 3%.
In the second half of 2019, the range will be supplemented by an efficient Plug-in Hybrid petrol powertrain with an extended ZEV range of 50km (WLTP cycle).
The batteries will be located under the row 2 seats to preserve the roomy boot.
