The start: 0 to 100 km/h

Off the line, the 911 Carrera 4 hits 100 km/h in 4.16 s versus 4.47 s for the 911 Carrera T. At this point, the 911 Carrera 4 leads by 0.31 s and sits roughly 4 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Carrera 4 is doing 155 km/h against 153 km/h for the 911 Carrera T. The gap is 0.24 s. The gap remains stable from the start.

At 400 metres standing start, the 911 Carrera 4 crosses the line in 12.19 s versus 12.47 s. The 0.28 s gap represents roughly 15 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 Carrera 4 continues to build its lead. At 600 metres, it runs at 215 km/h versus 216 km/h. At 1,000 metres, the 911 Carrera 4 finishes in 22.00 s versus 22.25 s, with a 0.25 s lead. Both vehicles have similar top speeds (286 vs 293 km/h), preventing any comeback.

What the numbers don’t tell you

The 911 Carrera 4 features all-wheel drive (AWD) against the 911 Carrera T’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 share the same electronic speed cap: the 911 Carrera 4 and the 911 Carrera T are governed to 291 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

With two combustion powertrains, the difference comes down to power-to-weight ratio (3.95 kg/hp vs 4.13 kg/hp) and transmission (Automatic vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.56 seconds. The 0.31 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
