BMW M340i xDrive Touring G20 vs Tesla Model 3 Long Range AWD: which is truly faster?

Off the line, the Model 3 Long Range AWD hits 100 km/h in 4.26 s versus 4.58 s for the M340i xDrive Touring. The instant torque of 637 Nm from the electric motor makes the difference. At this point, the Model 3 Long Range AWD leads by 0.32 s and sits roughly 2 m ahead.

At 200 metres, the Model 3 Long Range AWD is doing 145 km/h against 145 km/h for the M340i xDrive Touring. The gap is 0.16 s. The challenger starts to claw back ground.

At 400 metres standing start, the Model 3 Long Range AWD crosses the line in 12.62 s versus 12.74 s. The 0.12 s gap represents roughly 6 m of track - barely a car length.

Past 400 metres, the situation changes. The Model 3 Long Range AWD maxes out at 233 km/h while the M340i xDrive Touring keeps accelerating towards 250 (i.e. 155 mph - industry threshold) km/h. At 600 metres, the gap has dropped to 0.05 s.

Around 759 metres, both vehicles are level. This is the inversion point: the M340i xDrive Touring overcomes its launch deficit thanks to a 17 km/h higher top speed.

At 1,000 metres, the M340i xDrive Touring finishes in 23.11 s versus 23.17 s. The 0.06 s delta shows an extremely tight race.

Both rivals are electronically governed, but not at the same level: the M340i xDrive Touring is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Model 3 Long Range AWD at 233 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 6.92 seconds. The 0.32 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
