Off the line, the 718 Cayman hits 100 km/h in 4.56 s versus 5.14 s for the 840i. At this point, the 718 Cayman leads by 0.58 s and sits roughly 4 m ahead.
At 200 metres, the 718 Cayman is doing 149 km/h against 140 km/h for the 840i. The gap is 0.42 s. The challenger starts to claw back ground.
At 400 metres standing start, the 718 Cayman crosses the line in 12.65 s versus 13.35 s. The 0.70 s gap represents roughly 33 m of track - a gap visible to the naked eye.
Past 400 metres, the 718 Cayman continues to build its lead. At 600 metres, it runs at 206 km/h versus 195 km/h. At 1,000 metres, the 718 Cayman finishes in 22.89 s versus 24.12 s, with a 1.23 s lead.
Both rivals are electronically governed, but not at the same level: the 840i is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 718 Cayman at 274 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
With two combustion powertrains, the difference comes down to power-to-weight ratio (5.20 kg/hp vs 4.45 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.77 seconds. The 0.58 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
