BMW's M division has presented its second stand-alone production model - the BMW XM. We tested the 740bhp plug-in-petrol in prototype form
While the prototype is heavily disguised, the earlier concept revealed it will receive a large and uniquely shaped kidney grille set within a heavily structured bumper, giving it a purposeful look from straight on. As on the new 7 Series and facelifted X7, the headlights are split, with slim LED units above and main/dip beam lights below.
Buyers will be able to choose between two different outputs. As with the prototype driven here, the standard XM is set to offer 643bhp and 627lb ft. For those who consider that a little lacking, there will also be a more potent model with 740bhp and 738lb ft, as hinted at by the concept.Fittingly, this makes the XM the most powerful road car yet to wear the M badge, usurping the M5 CS to the tune of 114bhp in the process.
The electric motor draws its energy from a lithium ion battery with a capacity of “around 25kWh” mounted in three separate elements beneath the rear seat .It is produced exclusively for the XM, providing a claimed electric range of up to 50 miles at speeds of up to 80mph in electric mode. Charging of the battery can only be achieved on an AC system at up to 7.4kW.
The placement of major controls, including an electronic gear lever set high on the middle console, is spot on. Still, XM buyers will probably want to use the newly configured V8 every chance they get. With a combination of Hybrid and Sport modes, the XM’s performance is mesmerising and intimidating in equal measure.
