Panamera 4 E-Hybrid vs Bmw 745Le: chronicle of a drag race at 273 km/h
The launch: 0 to 100 km/h
Off the line, the Panamera 4 E-Hybrid hits 100 km/h in 4.56 s versus 5.36 s for the Bmw 745Le. At this point, the Panamera 4 E-Hybrid leads by 0.81 s and sits roughly 13 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Panamera 4 E-Hybrid is doing 143 km/h against 141 km/h for the Bmw 745Le. The gap is 0.59 s. The challenger starts to claw back ground.
At 400 metres standing start, the Panamera 4 E-Hybrid crosses the line in 12.86 s versus 13.47 s. The 0.61 s gap represents roughly 30 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the gap narrows. The Bmw 745Le maxes out at 250 km/h while the Panamera 4 E-Hybrid keeps accelerating towards 273 km/h. At 600 metres, the gap has dropped to 0.58 s.
At 1,000 metres, the Panamera 4 E-Hybrid finishes in 23.49 s versus 23.97 s, with just 0.48 s to spare. The Bmw 745Le fails to fully close the launch gap.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Panamera 4 E-Hybrid is capped at 278 km/h, the Bmw 745Le at 250 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 (4.93 kg/hp vs 5.19 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.84 seconds. The 0.81 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Panamera 4 E-Hybrid has a clear edge over the Bmw 745Le to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
