Four Tailpipes Show That the Neue Klasse BMW M3 Still Packs a Punch | Carscoops

      The beloved sports sedan maintains its inline-six engine with a mild-hybrid update, highlighting that high-performance engines are far from extinct.

      A prototype of the next-generation BMW M3 was recently spotted undergoing tests featuring inline-six internal combustion engine (ICE) power. BMW M officials previously indicated that this new model would incorporate mild-hybrid technology. The ICE variant of the M3 may debut approximately one year after the fully electric model.

      Performance vehicles are likely to be the last stronghold of the ICE era, yet BMW M is welcoming electrification. The low-selling XM has spearheaded this movement, and the sub-brand’s inaugural fully electric vehicle will be the M3.

      Numerous prototypes have been captured by spy photographers over the past year, and they have now successfully captured the gasoline-powered version. As evident, the sedan showcases a familiar Neue Klasse design that closely mirrors its electric sibling.

      Extra Airflow, Extra Purpose

      Upon closer examination, additional air intakes can be seen in the front bumper. While obscured by a mesh cover, it’s evident that this sports sedan requires adequate airflow.

      This change may be subtle, but the rear is unmistakably different. The ICE-powered M3 features a sporty quad exhaust system rather than a standard rear bumper, and the bumper itself has been redesigned with cutouts and a less aerodynamic profile.

      Details That Matter

      Overall, the rest of the vehicle remains familiar, yet it includes pronounced wheel arches and lightweight wheels supported by a high-performance braking system. Other notable features include flush-mounted door handles, a discreet rear spoiler, and a more dynamic side profile.

      While spy photographers didn’t capture the interior, prior images of the electric model suggest it will follow the layout of the new iX3. This means we can anticipate a Panoramic iDrive and Operating System X, alongside a 17.9-inch infotainment display and an updated steering wheel.

      What’s Under The Hood?

      Limited information is available regarding this model at present, but BMW M’s Head of Development, Dirk Häcker, previously noted that it will employ an inline-six engine paired with a 48-volt mild hybrid system. This setup is expected to enhance both performance and efficiency while avoiding the additional weight and charging challenges associated with a fully electric version.

      Details are scarce, but it’s anticipated that the model will feature a twin-turbo 3.0-liter inline-six engine, a compact battery, and an electric motor potentially integrated within the transmission. This should yield power outputs surpassing the current figures of 473 hp, 503 hp, and 523 hp.

      The extent of the performance increase remains uncertain, but we may have to wait some time to learn more, as the ICE-powered variant is likely to debut roughly a year after the M3 EV, suggesting a possible launch in 2028.
