Race simulation at real speed
CONFIDENCE 99%The Taycan 4S reaches 100 km/h first (3.95 s vs 4.11 s), but the Model X is ahead at every metre of the race. Explanation: the Model X accelerates harder at low speed and builds a distance gap before either car hits 100 km/h.
Why this result?
The Porsche Taycan 4S with Performance Battery Plus (PB) is faster at 0-100 km/h, but the Tesla Model X Long Range compensates at high speed thanks to higher peak power or top speed. At 400 m, Tesla Model X Long Range leads by 0.09 s.

Model X Long Range vs Taycan 4S with Performance Battery Plus (PB): chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the Taycan 4S with Performance Battery Plus (PB) hits 100 km/h in 3.95 s versus 4.11 s for the Model X Long Range. At this point, the Taycan 4S with Performance Battery Plus (PB) leads by 0.16 s and sits roughly 5 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Taycan 4S with Performance Battery Plus (PB) is doing 155 km/h against 160 km/h for the Model X Long Range. The gap is 0.05 s. The challenger starts to claw back ground.
At 400 metres standing start, the Model X Long Range crosses the line in 11.92 s versus 12.01 s. The 0.09 s gap represents roughly 5 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Model X Long Range continues to build its lead. At 600 metres, it runs at 224 km/h versus 218 km/h. At 1,000 metres, the Model X Long Range finishes in 21.31 s versus 21.62 s, with a 0.32 s lead. Both vehicles have similar top speeds (250 vs 250 km/h), preventing any comeback.
What the numbers don’t tell you
Both rivals share the same electronic speed cap: the Model X Long Range and the Taycan 4S with Performance Battery Plus (PB) are governed to 249 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.
With two electric powertrains, the difference comes down to power-to-weight ratio (3.51 kg/hp vs 3.99 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.88 seconds. The 0.16 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Taycan 4S with Performance Battery Plus (PB) is slightly faster than the Tesla Model X Long Range to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
