Both a 3.0 litre twin-turbo in-line six-cylinder petrol engine producing 269kW and the engine from the M3 and M4 performance heroes have reportedly been considered, with the latter producing 318kW.
The X4 range is currently headlined by the xDrive35i range-topper in Australia, with power coming from a 225kW/400Nm 3.0 litre turbocharged six-cylinder petrol engine returning 8.3 l/100km.
The top-spec X4 can reach 100km/h from rest in 5.5 seconds, so expect an M version to better this figure and offer more power than the xDrive35i. A diesel version – like it’s bigger X6 M50d sibling – is also a possibility.
BMW’s M characteristics are well disguised in these spy photos, although front styling reveals a marginally more aggressive look than the current X4.
The rear view differs from the regular X4 with tailpipes exiting either side of the vehicle, and perhaps a stronger LED-style appearance from the tail lamps.
Watch for a debut of the ‘X4 M’ midway through next year, with first deliveries in overseas markets to take place in 2016.
