Spy Photos Confirm Next BMW M3 With Inline-Six ICE and Quad Exhausts

Overview

• Fresh images show a camouflaged M3 mule with four tailpipes, widened arches, lightweight wheels, and large cross‑drilled brakes, identifying it as an internal‑combustion development car.
• BMW is developing both an electric M3 and a separate six‑cylinder petrol M3, with the EV slated to launch first based on the Neue Klasse platform.
• BMW M’s development chief has indicated the petrol model will use a 48‑volt mild‑hybrid inline‑six, a lighter approach than the plug‑in hybrid setup used in the new M5.
• Reporting points to an eight‑speed automatic and xDrive as likely, with the six‑speed manual expected to be discontinued.
• The prototype exhibits Neue Klasse cues such as an elongated horizontal grille and flush door handles, while retaining classic M signatures including the quad exhaust layout.
