The start: 0 to 100 km/h

Off the line, the M8 Competition Convertible hits 100 km/h in 3.32 s versus 3.92 s for the Panamera Turbo. At this point, the M8 Competition Convertible leads by 0.60 s and sits roughly 3 m ahead.

From 100 km/h to 400 metres

At 200 metres, the M8 Competition Convertible is doing 168 km/h against 153 km/h for the Panamera Turbo. The gap is 0.52 s. The gap remains stable from the start.

At 400 metres standing start, the M8 Competition Convertible crosses the line in 11.14 s versus 12.01 s. The 0.87 s gap represents roughly 45 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the M8 Competition Convertible continues to build its lead. At 600 metres, it runs at 234 km/h versus 213 km/h. At 1,000 metres, the M8 Competition Convertible finishes in 20.23 s versus 21.90 s, with a 1.67 s lead. Despite a higher top speed (293 km/h), the Panamera Turbo never recovers its launch deficit.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the M8 Competition Convertible is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Panamera Turbo at 303 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 (3.24 kg/hp vs 3.58 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.84 seconds. The 0.60 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
