Porsche Taycan GTS J1.1 vs BMW i5 eDrive40 G60: which is truly faster?

Off the line, the Taycan GTS hits 100 km/h in 3.65 s versus 6.12 s for the i5 eDrive40. At this point, the Taycan GTS leads by 2.48 s and sits roughly 23 m ahead.

At 200 metres, the Taycan GTS is doing 156 km/h against 135 km/h for the i5 eDrive40. The gap is 1.88 s. The challenger starts to claw back ground.

At 400 metres standing start, the Taycan GTS crosses the line in 11.75 s versus 14.29 s. The 2.55 s gap represents roughly 112 m of track - a gap visible to the naked eye.

Past 400 metres, the Taycan GTS continues to build its lead. At 600 metres, it runs at 219 km/h versus 186 km/h. At 1,000 metres, the Taycan GTS finishes in 21.32 s versus 25.87 s, with a 4.55 s lead.

The Taycan GTS features all-wheel drive (AWD) against the i5 eDrive40’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 Taycan GTS is capped at 249 (i.e. 155 mph - industry threshold) km/h, the i5 eDrive40 at 193 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 electric powertrains, the difference comes down to power-to-weight ratio (3.90 kg/hp vs 6.81 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.92 seconds. The 2.48 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
