Porsche 911 Turbo S 992 vs Porsche Boxster S 987: which is truly faster?

Off the line, the 911 Turbo S hits 100 km/h in 2.53 s versus 5.07 s for the Boxster S. At this point, the 911 Turbo S leads by 2.54 s and sits roughly 17 m ahead.

At 200 metres, the 911 Turbo S is doing 185 km/h against 143 km/h for the Boxster S. The gap is 2.18 s. The challenger starts to claw back ground.

At 400 metres standing start, the 911 Turbo S crosses the line in 10.00 s versus 13.18 s. The 3.18 s gap represents roughly 147 m of track - a gap visible to the naked eye.

Past 400 metres, the 911 Turbo S continues to build its lead. At 600 metres, it runs at 257 km/h versus 199 km/h. At 1,000 metres, the 911 Turbo S finishes in 18.17 s versus 23.72 s, with a 5.55 s lead.

The 911 Turbo S features all-wheel drive (AWD) against the Boxster S’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.

Both rivals are electronically governed, but not at the same level: the 911 Turbo S is capped at 322 (i.e. 200 mph - industry threshold) km/h, the Boxster S at 272 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 (2.43 kg/hp vs 4.39 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.54 seconds. The 2.54 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
