Mercedes G 450 d W463 vs Cupra Terramar: which is truly faster?

Off the line, the G 450 d hits 100 km/h in 5.83 s versus 8.31 s for the Terramar. Despite lacking instant torque, 367 hp of power compensates. At this point, the G 450 d leads by 2.48 s and sits roughly 31 m ahead.

At 200 metres, the G 450 d is doing 128 km/h against 116 km/h for the Terramar. The gap is 1.64 s. The challenger starts to claw back ground.

At 400 metres standing start, the G 450 d crosses the line in 14.11 s versus 16.25 s. The 2.14 s gap represents roughly 83 m of track - a gap visible to the naked eye.

Past 400 metres, the G 450 d continues to build its lead. At 600 metres, it runs at 174 km/h versus 160 km/h. At 1,000 metres, the G 450 d finishes in 26.22 s versus 29.41 s, with a 3.19 s lead. Both vehicles have similar top speeds (210 vs 214 km/h), preventing any comeback.

The G 450 d features all-wheel drive (AWD) against the Terramar’s FWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.

Electronically capped at 210 km/h, the G 450 d never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.30 seconds. The 2.48 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
