While the 2026 BMW 4 Series is widely celebrated for its low center of gravity and aerodynamic silhouette, its engineering versatility extends to practical utility. For 2026, the 4 Series retains a surprisingly robust towing capacity, making it a viable option for Grand Rapids drivers who need to transport light recreational equipment without upgrading to an SAV.
| Configuration | Engine | Braked Towing Capacity | Unbraked Towing Capacity |
|---|---|---|---|
| 430i Coupe (RWD) | 2.0L Inline-4 Turbo | 1,600 kg (3,527 lbs) | 750 kg (1,653 lbs) |
| M440i xDrive (AWD) | 3.0L Inline-6 Turbo | 1,800 kg (3,968 lbs) | 750 kg (1,653 lbs) |
| 430i Convertible | 2.0L Inline-4 Turbo | 1,600 kg (3,527 lbs) | 750 kg (1,653 lbs) |
| i4 Gran Coupe | Electric | 1,600 kg (3,527 lbs) | 750 kg (1,653 lbs) |
The ability to tow nearly 4,000 lbs in an M440i xDrive is a direct result of the CLAR (Cluster Architecture) platform, which provides high torsional rigidity through the use of high-strength steel and aluminum reinforcements.
