The G31 BMW 5 Series Touring has been spotted out on test again, this time wearing a little less camouflage than during its previous sighting. This one appears to be of the Luxury trim variant, though an earlier sighting also revealed what seemed like an M Sport-kitted version, so both can be expected when the facelift arrives.

There’s less cladding on the fascia of the development vehicle here compared to previous sightings, and here the kidney grille appears to have largely remained in size relative to that on the current, pre-facelift model. The crease lines and other aesthetic features appear to remain unchanged along the sides, while further exterior changes to the car’s rear end include a revised bumper and tail lights.

The previous sighting of the updated G31’s interior reveal that this set of revisions will bring the Live Cockpit driver instrumentation as featured in the G20 3 Series and the G29 Z4, though the centre console at the time appears to be unchanged from the current car, and therefore different from those in the 3 Series and the Z4.

While the G31 and its G30 sedan sibling may receive a modest set of changes in terms of styling, the update is expected to bring the company’s 3.0 litre inline-six petrol-electric plug-in hybrid powertrain to the 5 Series line-up and be badged 545e, which will replace the existing 530e.

This already features in the G11/G12 7 Series range, though this powertrain can expected to serve in the 5 Series with a mild detune. Further along, four- and six-cylinder petrols and diesels are also expected to continue in the facelift. As for its debut, the G31 5 Series Touring could arrive in 2021, to follow shortly after the facelifted G30 sedan which is expected at the end of next year, or early 2021.
