Brief Description
The 2025 Life-Cycle Impulse enhances its grand touring identity with new arrow-shaped LED DRLs, an optional Iconic Glow grille, and more sculpted air intakes. The cabin features the Curved Display (12.3″ cluster + 14.9″ infotainment) running BMW OS 9 and a two-spoke steering wheel, along with crystal CraftedClarity trims and Multifunction seats. The aluminum/carbon body remains dimensionally unchanged (Coupé 4,851 × 1,902 × 1,346 mm; wheelbase 2,822 mm) but gains stiffer suspension mounts (+10%) for sharper steering response. Adaptive M suspension and Integral Active Steering are standard across all models.
