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 4.30 s for the Model X Long Range. At this point, the Taycan 4S with Performance Battery Plus (PB) leads by 0.35 s and sits roughly 7 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 158 km/h for the Model X Long Range. The gap is 0.20 s. The challenger starts to claw back ground.
At 400 metres standing start, the Taycan 4S with Performance Battery Plus (PB) crosses the line in 12.01 s versus 12.14 s. The 0.13 s gap represents roughly 7 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the gap narrows.
At 1,000 metres, the Taycan 4S with Performance Battery Plus (PB) finishes in 21.62 s versus 21.65 s, with just 0.02 s to spare. The Model X Long Range fails to fully close the launch gap.
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 (3.67 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 5.92 seconds. The 0.35 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.
