BMW M model buyers aren’t cross-shopping between M cars from the brand’s performance arm, according to its global boss – meaning its model range isn’t cannibalising itself by being too close in terms of capability.

The latest model is the M2 CS – the third ‘Competition Sport’ model in local showrooms, and sitting above the standard M2 – which is priced at $172,900 before on-road costs, making it more than a regular BMW M3.

The M2 CS brings a 30kg weight saving over the standard M2 and is offered as rear-wheel drive only, with the same (limited) 302km/h top speed as all other CS models.

The smallest and most affordable M car also has a 0-100km/h claim of 3.8 seconds – while the M3 CS Touring takes 3.5 seconds, with the M4 CS a tenth of a second quicker at 3.4 seconds.

Yet the M2 CS is less than a single kilowatt down on the flagship M4 CS’s 230.11kW/tonne power-to-weight ratio (based on Euro specs), at 229.4kW/tonne.

It’s also only 3.6 seconds slower around the 20.832-kilometre Nürburgring Nordschleife racetrack in Germany, its 7:25.53 lap well in the mirrors of the M4 CS’s 7:21.989 time.

This all comes for $82,000 less than the M4 CS’s $254,900 before on-road costs price.

But buyers aren’t shopping between CS models on price, says M Division boss Frank van Meel, when asked if the similar on-paper performance between the trio sold here was an issue for customers.
