BMW i5 eDrive40 G60 vs Mercedes S 350 d 4MATIC Limousine Langversion W223: which is truly faster?

Off the line, the S 350 d 4MATIC Limousine Langversion hits 100 km/h in 5.47 s versus 6.12 s for the i5 eDrive40. Despite lacking instant torque, 313 hp of power compensates. At this point, the S 350 d 4MATIC Limousine Langversion leads by 0.65 s and sits roughly 21 m ahead.

At 200 metres, the S 350 d 4MATIC Limousine Langversion is doing 131 km/h against 135 km/h for the i5 eDrive40. The gap is 0.71 s. The gap remains stable from the start.

At 400 metres standing start, the S 350 d 4MATIC Limousine Langversion crosses the line in 13.68 s versus 14.29 s. The 0.61 s gap represents roughly 28 m of track - two to three car lengths.

Past 400 metres, the S 350 d 4MATIC Limousine Langversion continues to build its lead. At 600 metres, it runs at 185 km/h versus 186 km/h. At 1,000 metres, the S 350 d 4MATIC Limousine Langversion finishes in 24.99 s versus 25.87 s, with a 0.88 s lead.

The S 350 d 4MATIC Limousine Langversion 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 i5 eDrive40 is capped at 193 km/h, the S 350 d 4MATIC Limousine Langversion 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.92 seconds. The 0.65 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
