The next-gen G02 BMW X4 has been sighted – our spy photographers caught a camouflaged prototype on a transporter, sharing a ride with a number of BMW/MINI evaluation mules.

The replacement for the current – and short-lived – F26 X4 is slated to enter the market in 2018, and by all accounts (including the lighter level of disguise seen here) should be ready to make its appearance by the end of the year, following on the new G01 X3’s arrival.

Like the X3, the new X4 will sit on the automaker’s rear-biased Cluster Architecture (CLAR) platform, which offers greater interior space and a more practical and comfortable seating system. It’s also set to be lighter proposition than the current example – expect there to be similar weight savings as that touted for the GO1 (up to 100 kg).

Engine choices for the new sports activity coupe will mirror those of the new X3, with the usual 2.0 litre four-cylinder and 3.0 litre straight-six turbo petrol and diesel engines making the line-up.

As before, an M40i variant looks to be on the cards, with output expected to be closer to 400 hp this time around, and with the G01 slated to go the full-on M route, an X4 M is sure to follow – word is that the M4’s twin-turbo 3.0 litre six-pot will offer around 500 hp in the applications here.
