Within 24 hours of their official reveal, the all-new BMW M3 and M4 have been leaked via social media.

    Posted to @carswithoutlimits on Instagram, the images show both the M3 sedan and M4 coupe in deep green and bright yellow respectively, also offering a proper look at the polarising new nose for both models that first debuted on the standard 4 Series.

    In keeping with previous-generation models, the new M3 and M4 get more aggressive body kits, large multi-spoke alloy wheels with low-profile tyres, a quad-tipped exhaust out back, boot lid spoilers, slits in the bonnet, and what looks like carbon-fibre roofs – indicating the models pictured are high-spec Competition variants.

    The distinctive spurred side mirrors also feature on both models, as do what appears to be BMW’s flagship Laserlight headlights.

    Further details haven’t been published with the photos on Instagram, though we’ve heard plenty of preliminary facts from BMW itself in the lead-up to the official September 23 reveal.

    Power will come from a new-generation 3.0-litre twin-turbo inline six that first featured in the X3 M and X4 M, expected to be available in two states of tune – a ‘standard’ 353kW/600Nm version and a high-spec ‘Competition’ model with 375kW/600Nm.

    For the first time, the M3 and M4 will be offered with rear-wheel drive and M xDrive variable all-wheel drive, as well as the choice of six-speed manual and eight-speed torque converter automatic transmissions.

    We’ll also see the first-ever M3 Touring wagon, though the RS4 Avant rival isn’t expected to hit the market until around 2023.

    Thanks to the added traction of all-wheel drive, the M3 and M4 should be capable of hitting triple figures in well under 4.0 seconds.

    Expect to see a limited top speed of 250km/h from the factory, with the option to raise that to around 300km/h by ticking a the M Driver’s Package option box.
