The new BMW M5 is set for an imminent unveiling after numerous teasers, leaks and spy photos, and the German brand has previewed its new-generation performance sedan.

    Actually, this time around it will be both a high-performance sedan and wagon, the first time BMW will offer a long-roof M5 since the E60/E61 generation that ended production in 2010.

    The single teaser image shared by BMW USA on Twitter shows the sedan under a sheet, revealing the vertically oriented LED daytime running light signatures and illuminated grille surrounds that are becoming increasingly common within the BMW range.

    BMW still hasn’t confirmed what will power the new M5, but a post earlier this year on fan forum Bimmerpost by user ‘ynguldyn’ – who claims to compile future BMW model information from company insiders – revealed key figures for the new M5.

    It will reportedly be the most powerful and heaviest version of the performance model ever, using the same 4.4-litre twin-turbo V8 engine and plug-in hybrid system of the XM SUV albeit with higher outputs.

    While the BMW XM produces 550kW and 1000Nm in Label Red guise from its petrol engine and electric motor, the M5 will reportedly receive a boost to reach 575kW and 1030Nm.

    That’s a significant increase over the model’s peak figures, with the outgoing generation M5 CS limited edition producing 467kW and 750Nm.

    The upcoming BMW M5 will reportedly have a smaller battery than the XM, downsizing from the SUV’s 25.7kWh lithium-ion pack to a 18.6kWh unit. BMW claims an electric-only driving range of 88km for the XM.

    Despite the smaller battery pack, the 2025 BMW M5 will still reportedly be the heaviest car to wear the 40-year-old nameplate, reportedly tipping the scales at 2435kg – the first M5 to crack two tonnes. The XM Label Red weighs 2720kg.

    The BMW insider also claims the M5 will grow in size compared to the regular 5 Series, measuring 5096mm in length (up 36mm) and 1970mm wide (up 70mm), with a longer wheelbase due to “new suspension geometry”.

    Production of the M5 sedan will reportedly begin in July 2024, with the M5 Touring following in November 2024.

    It’ll go up against two new-generation rivals which have yet to be revealed: the next Mercedes-AMG E 63, which is expected to pack a plug-in hybrid six-cylinder powertrain; and a new Audi RS7, replacing the current RS6 and RS7 models and also getting plug-in hybrid power.
