The start: 0 to 100 km/h

Off the line, the Boxster Spyder hits 100 km/h in 4.75 s versus 5.58 s for the Cayman (PDK). At this point, the Boxster Spyder leads by 0.84 s and sits roughly 7 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Boxster Spyder is doing 148 km/h against 137 km/h for the Cayman (PDK). The gap is 0.53 s. The challenger starts to claw back ground.

At 400 metres standing start, the Boxster Spyder crosses the line in 12.80 s versus 13.65 s. The 0.84 s gap represents roughly 40 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Boxster Spyder continues to build its lead. At 600 metres, it runs at 206 km/h versus 194 km/h. At 1,000 metres, the Boxster Spyder finishes in 22.97 s versus 24.50 s, with a 1.53 s lead. Both vehicles have similar top speeds (272 vs 261 km/h), preventing any comeback.

What the numbers don’t tell you

With two combustion powertrains, the difference comes down to power-to-weight ratio (3.98 kg/hp vs 5.06 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.22 seconds. The 0.84 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
