The start: 0 to 100 km/h

Off the line, the 740Le iPerformance hits 100 km/h in 5.58 s versus 6.06 s for the 630d Gran Turismo. The instant torque of 400 Nm from the electric motor makes the difference. At this point, the 740Le iPerformance leads by 0.48 s and sits roughly 6 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 740Le iPerformance is doing 132 km/h against 127 km/h for the 630d Gran Turismo. The gap is 0.34 s. The challenger starts to claw back ground.

At 400 metres standing start, the 740Le iPerformance crosses the line in 13.77 s versus 14.32 s. The 0.55 s gap represents roughly 24 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 740Le iPerformance continues to build its lead. At 600 metres, it runs at 186 km/h versus 177 km/h. At 1,000 metres, the 740Le iPerformance finishes in 25.05 s versus 26.17 s, with a 1.12 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the 740Le iPerformance and the 630d Gran Turismo are governed to 250 (i.e. 155 mph - industry threshold) 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.

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 9.67 seconds. The 0.48 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
