Tesla Model 3 Long Range AWD vs BMW M340d xDrive Touring G20: which is truly faster?

Off the line, the Model 3 Long Range AWD hits 100 km/h in 4.44 s versus 4.76 s for the M340d xDrive Touring. The instant torque of 605 Nm from the electric motor makes the difference. Despite the faster sprint time, the M340d xDrive Touring is 2 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.

At 200 metres, the Model 3 Long Range AWD is doing 143 km/h against 137 km/h for the M340d xDrive Touring. The gap is 0.13 s. The challenger starts to claw back ground.

At 400 metres standing start, the Model 3 Long Range AWD crosses the line in 12.80 s versus 13.08 s. The 0.28 s gap represents roughly 13 m of track - two to three car lengths.

Past 400 metres, the Model 3 Long Range AWD continues to build its lead. At 600 metres, it runs at 196 km/h versus 192 km/h. At 1,000 metres, the Model 3 Long Range AWD finishes in 23.49 s versus 24.00 s, with a 0.51 s lead. Despite a higher top speed (250 (i.e. 155 mph - industry threshold) km/h), the M340d xDrive Touring never recovers its launch deficit.

Both rivals are electronically governed, but not at the same level: the Model 3 Long Range AWD is capped at 233 km/h, the M340d xDrive Touring at 250 (i.e. 155 mph - industry threshold) 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 7.61 seconds. The 0.32 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
