Taycan vs Bmw M340d xDrive Touring: chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw M340d xDrive Touring hits 100 km/h in 4.60 s versus 5.13 s for the Taycan. Despite lacking instant torque, 335 hp of power compensates. At this point, the Bmw M340d xDrive Touring leads by 0.53 s and sits roughly 18 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw M340d xDrive Touring is doing 138 km/h against 148 km/h for the Taycan. The gap is 0.46 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M340d xDrive Touring crosses the line in 12.92 s versus 13.02 s. The 0.10 s gap represents roughly 5 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The Taycan maxes out at 230 km/h while the Bmw M340d xDrive Touring keeps accelerating towards 250 km/h. At 600 metres, the gap has dropped to 0.28 s.
Around 452 metres, both vehicles are level. This is the inversion point: the Taycan overcomes its launch deficit thanks to a 20 km/h higher top speed.
At 1,000 metres, the Taycan finishes in 22.91 s versus 23.77 s. The 0.86 s delta in favour of the Taycan shows that top speed makes a clear difference.
What the numbers don’t tell you
The Bmw M340d xDrive Touring features all-wheel drive (AWD) against the Taycan’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the Taycan is capped at 230 km/h, the Bmw M340d xDrive Touring 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.
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 7.38 seconds. The 0.53 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw M340d xDrive Touring has a clear edge over the Porsche Taycan to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
