911 Targa 4 vs ID.5 GTX: chronicle of a drag race at 281 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Targa 4 hits 100 km/h in 5.16 s versus 6.24 s for the ID.5 GTX. Despite lacking instant torque, 355 hp of power compensates. At this point, the 911 Targa 4 leads by 1.08 s and sits roughly 10 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Targa 4 is doing 141 km/h against 128 km/h for the ID.5 GTX. The gap is 0.75 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Targa 4 crosses the line in 13.20 s versus 14.53 s. The 1.33 s gap represents roughly 57 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Targa 4 continues to build its lead. At 600 metres, it runs at 201 km/h versus 175 km/h. At 1,000 metres, the 911 Targa 4 finishes in 23.67 s versus 26.88 s, with a 3.20 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the 911 Targa 4 is capped at 282 km/h, the ID.5 GTX at 180 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.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.81 seconds. The 1.08 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Targa 4 has a clear edge over the Volkswagen ID.5 GTX to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
