Off the line, the GR86 hits 100 km/h in 6.20 s versus 7.75 s for the 420d Convertible. At this point, the GR86 leads by 1.55 s and sits roughly 2 m ahead.
At 200 metres, the GR86 is doing 132 km/h against 116 km/h for the 420d Convertible. The gap is 0.57 s. The challenger starts to claw back ground.
At 400 metres standing start, the GR86 crosses the line in 14.35 s versus 15.64 s. The 1.29 s gap represents roughly 50 m of track - a gap visible to the naked eye.
Past 400 metres, the GR86 continues to build its lead. At 600 metres, it runs at 179 km/h versus 161 km/h. At 1,000 metres, the GR86 finishes in 26.10 s versus 28.69 s, with a 2.59 s lead. Both vehicles have similar top speeds (223 vs 236 km/h), preventing any comeback.
Electronically capped at 236 km/h, the 420d Convertible 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.
With two combustion powertrains, the difference comes down to power-to-weight ratio (5.34 kg/hp vs 9.34 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.82 seconds. The 1.55 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, GR86 wins (6,20 s vs 7,75 s).
GR86 goes from 0 to 100 km/h in 6,20 seconds (calibrated simulation).
