The start: 0 to 100 km/h

Off the line, the 718 Boxster S hits 100 km/h in 4.16 s versus 7.43 s for the 220d xDrive Gran Coupe. At this point, the 718 Boxster S leads by 3.27 s and sits roughly 16 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 718 Boxster S is doing 157 km/h against 118 km/h for the 220d xDrive Gran Coupe. The gap is 2.01 s. The challenger starts to claw back ground.

At 400 metres standing start, the 718 Boxster S crosses the line in 12.06 s versus 15.43 s. The 3.38 s gap represents roughly 129 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 718 Boxster S continues to build its lead. At 600 metres, it runs at 218 km/h versus 163 km/h. At 1,000 metres, the 718 Boxster S finishes in 21.69 s versus 28.31 s, with a 6.61 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 718 Boxster S is capped at 285 km/h, the 220d xDrive Gran Coupe at 234 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 (3.87 kg/hp vs 8.24 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.14 seconds. The 3.27 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
