Grand Cherokee 4xe vs Boxster S: chronicle of a drag race at 273 km/h
The launch: 0 to 100 km/h
Off the line, the Boxster S hits 100 km/h in 4.94 s versus 6.04 s for the Grand Cherokee 4xe. At this point, the Boxster S leads by 1.10 s and sits roughly 9 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Boxster S is doing 145 km/h against 130 km/h for the Grand Cherokee 4xe. The gap is 0.75 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster S crosses the line in 13.01 s versus 14.27 s. The 1.26 s gap represents roughly 55 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Boxster S continues to build its lead. At 600 metres, it runs at 202 km/h versus 182 km/h. At 1,000 metres, the Boxster S finishes in 23.47 s versus 25.86 s, with a 2.39 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Grand Cherokee 4xe is capped at 210 km/h, the Boxster S at 279 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 (6.62 kg/hp vs 4.14 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.33 seconds. The 1.10 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Boxster S has a clear edge over the Jeep Grand Cherokee 4xe to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
