The start: 0 to 100 km/h

Off the line, the Boxster S hits 100 km/h in 5.07 s versus 5.81 s for the TT 45 TFSI. At this point, the Boxster S leads by 0.74 s and sits roughly 8 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Boxster S is doing 143 km/h against 133 km/h for the TT 45 TFSI. The gap is 0.54 s. The challenger starts to claw back ground.

At 400 metres standing start, the Boxster S crosses the line in 13.18 s versus 14.06 s. The 0.88 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 S continues to build its lead. At 600 metres, it runs at 199 km/h versus 184 km/h. At 1,000 metres, the Boxster S finishes in 23.72 s versus 25.49 s, with a 1.77 s lead.

What the numbers don’t tell you

Electronically capped at 272 km/h, the Boxster S 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 (4.39 kg/hp vs 5.43 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.89 seconds. The 0.74 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
