Under the bonnet

Manufacturer technical specifications. The power-to-weight ratio is the key physical factor in a drag race.

The start: 0 to 100 km/h

Off the line, the 911 Turbo S hits 100 km/h in 2.95 s versus 5.73 s for the Bmw 430i. At this point, the 911 Turbo S leads by 2.78 s and sits roughly 16 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Turbo S is doing 176 km/h against 132 km/h for the Bmw 430i. The gap is 2.19 s. The challenger starts to claw back ground.

At 400 metres standing start, the 911 Turbo S crosses the line in 10.57 s versus 13.97 s. The 3.40 s gap represents roughly 146 m of track — a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 Turbo S continues to build its lead. At 600 metres, it runs at 243 km/h versus 185 km/h. At 1,000 metres, the 911 Turbo S finishes in 19.22 s versus 25.35 s, with a 6.13 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 911 Turbo S is capped at 317 km/h, the Bmw 430i at 250 (i.e. 155 mph — industry threshold) 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 (2.83 kg/hp vs 5.99 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.91 seconds. The 2.78 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
