The start: 0 to 100 km/h

Off the line, the A110 GT 300 hits 100 km/h in 3.92 s versus 4.53 s for the 911 Targa 4S. At this point, the A110 GT 300 leads by 0.62 s and sits roughly 4 m ahead.

From 100 km/h to 400 metres

At 200 metres, the A110 GT 300 is doing 157 km/h against 150 km/h for the 911 Targa 4S. The gap is 0.40 s. The challenger starts to claw back ground.

At 400 metres standing start, the A110 GT 300 crosses the line in 11.96 s versus 12.49 s. The 0.52 s gap represents roughly 27 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the A110 GT 300 continues to build its lead. At 600 metres, it runs at 215 km/h versus 213 km/h. At 1,000 metres, the A110 GT 300 finishes in 21.76 s versus 22.38 s, with a 0.62 s lead. Despite a higher top speed (295 km/h), the 911 Targa 4S never recovers its launch deficit.

What the numbers don’t tell you

Electronically capped at 295 km/h, the 911 Targa 4S 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 (3.83 kg/hp vs 3.65 kg/hp) and transmission (Manual vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.68 seconds. The 0.62 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
