2025 BMW M5: Plug-in hybrid to bring big power boost
The upcoming 2025 BMW M5 will be the most powerful – and heaviest – version of the performance model ever, according to sources close to the brand.
In a post on fan forum Bimmerpost, user ‘ynguldyn’ – who claims to compile future BMW model information from company insiders – announced key figures for the new generation M5 sedan and wagon (the latter known as the M5 Touring).
According to the insider information, the BMW M5 will share the same 4.4-litre twin-turbo V8 engine and plug-in hybrid system as 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 – 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 reduced size 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”.
The new BMW M5 will see the return of the Touring wagon for the first time since 2010, when the V10-powered E61 M5 was offered as a long-roof but only in Europe – accounting for little more than 1000 of the model’s total 20,000 sales after it launched in 2005.
Production of the M5 sedan will reportedly begin in July 2024, with the M5 Touring following in November 2024.
In March 2027 it’s expected a mid-life update will bring BMW’s ‘Panoramic Vision’ interface to the M5, ahead of production ending in February 2031.
