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 Carrera 4S (PDK w/Sport Chrono Package Plus) hits 100 km/h in 4.20 s versus 4.54 s for the Bmw Z4 M40i. At this point, the 911 Carrera 4S (PDK w/Sport Chrono Package Plus) leads by 0.34 s and sits roughly 5 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Carrera 4S (PDK w/Sport Chrono Package Plus) is doing 154 km/h against 147 km/h for the Bmw Z4 M40i. The gap is 0.32 s. The gap remains stable from the start.

At 400 metres standing start, the 911 Carrera 4S (PDK w/Sport Chrono Package Plus) crosses the line in 12.19 s versus 12.70 s. The 0.51 s gap represents roughly 26 m of track — two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 Carrera 4S (PDK w/Sport Chrono Package Plus) continues to build its lead. At 600 metres, it runs at 214 km/h versus 205 km/h. At 1,000 metres, the 911 Carrera 4S (PDK w/Sport Chrono Package Plus) finishes in 21.99 s versus 22.95 s, with a 0.95 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 911 Carrera 4S (PDK w/Sport Chrono Package Plus) is capped at 295 km/h, the Bmw Z4 M40i 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 (3.87 kg/hp vs 4.51 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.76 seconds. The 0.34 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
