A revealing prototype for the fourth-generation BMW X5 SUV was spotted testing on public roads with most of its lines and styling details properly visible.

Until now, our best look at the 2019 X5 came back in November when two lightly-covered prototypes were seen just outside BMW‘s Spartanburg factory.

In these spy shots from our CarPix partners we can see even more details, such as the LED fog lights, or the belt line that climbs towards the rear door handle and then continues its path towards the edge of the taillights. It makes the all-new X5 appear more muscular than the outgoing model.

We had a feeling the redesigned taillights might be smaller than before, towards the inner and outer edges. And indeed, gone are the L-shape units, replaced by a sharper, sort of horizontal fang, perhaps a little reminiscent of the taillights on an Audi Q5.

By utilizing the CLAR (cluster architecture) platform, like the all-new 5 and 7-Series models, the 2019 BMW X5 is said to be longer, lighter and more rigid. Inside, we expect it to boast at least the same level of active safety and connectivity as the 5-Series, while providing passengers with more room for themselves as well as for their luggage.

A variety of petrol and diesel units should be available across the range, while the flagship X5 M version is expected to pack the same 4.4-liter TwinPower Turbo V8 engine that breathes life into the all-new M5. A total of 600 or more HP should be available for the X5 M.

The 2019 BMW X5 will be unveiled sometime later this year.
