BMW has revealed its its new M Performance parts for the new-generation M5 super sedan, along with a special M3 30 Years American Edition for the US market.

Set to be displayed at the 2017 SEMA show, the M Performance parts on the new M5 have already been previewed by the new MotoGP safety car, and are all crafted from carbon-fibre.

The accessories include a front splitter, side skirts, rear spoiler and a rear diffuser. BMW claims that these parts not only enhance the visual appeal of its new-generation super sedan, but also providing "optimised aerodynamic characteristics" for "even sportier handling".

Other M Performance goodies on offer are the carbon-fibre grille surrounds, a coilover suspension system, sports pads for the carbon-ceramic brakes, an M Performance sports exhaust system - which is made from titanium and finished with carbon-fibre exhaust tips - along with the M Performance Drive Analyser, which records vehicle dynamics data and allows these statistics to be monitored via the M Performance Drive Analyser smartphone app.

BMW's global arm says most of these accessories will be offered as retrofit components when the M5 launches in March 2018, with further products coming in July. Confirmation and timing for the Australian market is still to be determined – CarAdvice has contacted the local division for details.

Meanwhile, the SEMA show will also serve as the launch pad for the M3 30 Years American Edition, which celebrates the 30th anniversary of the nameplate in the US.

Combining the red, white and blue colours of the American flag, the limited-edition M3 features a six-speed manual transmission, Frozen Red II metallic paint, M Performance Golden light alloy wheels (19-inch front and 20-inch rear) - the colour is inspired by the E30 M3's DTM racing wheels - and a 30th anniversary graphic applied to the rear sunshade.

Inside, there's appropriately patriotic tri-colour Merino leather in red, white and blue, highlighted by contrasting stitching on the seats and dashboard. There's also M Performance sports suspension, a fixed M Performance carbon-fibre rear wing, along with M Performance door handles, shift knob and centre armrest.

The BMW M3 30 Years American Edition is a one-off special that is "expected to be available for purchase" following the SEMA show.
