Displacement: 2,999 cc (GLS 450) / 3,982 cc (GLS 580)
The 2026 Mercedes-Benz GLS-Class (X167 Facelift) remains the "S-Class of SUVs," recently updated with enhanced mild-hybrid powertrains. In Pakistan, the most sought-after variants are the GLS 450, featuring a 3.0L turbocharged inline-six, and the powerhouse GLS 580 with its 4.0L biturbo V8. Both engines utilize a 48V mild-hybrid system (ISG), which provides an additional 21–23 hp and substantial torque assistance, ensuring this massive 7-seater feels effortless even when climbing the steep gradients of the Murree Expressway.
Max Power: 375 hp (GLS 450) / 510–530 hp (GLS 580)
The 2026 facelift brings a power bump for the flagship V8. The GLS 450 delivers a steady 375 hp, while the GLS 580 now produces between 510 and 530 hp (market dependent). For those seeking the absolute peak of luxury and performance, the Maybach GLS 600 and AMG GLS 63 variants push the output toward 600+ hp, providing "private jet" levels of acceleration for the Pakistani elite.
Max Torque: 500 Nm (GLS 450) / 700–750 Nm (GLS 580)
Torque is where the GLS excels, providing the "wafting" sensation characteristic of the brand. The GLS 450 offers 500 Nm (369 lb-ft), while the updated GLS 580 delivers a massive 750 Nm (553 lb-ft). This immense pulling power is critical for its 3,500 kg towing capacity and ensures that the vehicle remains composed regardless of how many passengers or how much luggage is on board.
