In the same way that the M Performance line denotes 'sportier' versions of BMW's wider range - those that aren't quite full M-spec - the iPerformance moniker applies to hybrid versions of the standard line-up, leaving the 'real' i-range cars to stand alone.
It's all part of a broader product strategy, called 'Number One Next', that BMW is using to spearhead the next generation of its automotive technology.
The X5 was chosen to lead the local charge (ba-doom) as it is the highest-selling model variant in Australia. Next in line is the 330e hybrid 3 Series sedan which will follow in May this year.
While BMW has not confirmed which models will follow in our market, a 740e model was unveiled at the 2016 Geneva Motor Show. And, given the next-generation X3 and 5 Series are both currently due to arrive in 2017, it would be reasonable to assume there will be iPerformance models for each of these.
