911 GT3 vs Bmw M340i xDrive Touring: chronicle of a drag race at 313 km/h
The launch: 0 to 100 km/h
Off the line, the 911 GT3 hits 100 km/h in 4.08 s versus 4.58 s for the Bmw M340i xDrive Touring. At this point, the 911 GT3 leads by 0.50 s and sits roughly 4 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 GT3 is doing 158 km/h against 145 km/h for the Bmw M340i xDrive Touring. The gap is 0.48 s. The gap remains stable from the start.
At 400 metres standing start, the 911 GT3 crosses the line in 11.85 s versus 12.74 s. The 0.88 s gap represents roughly 43 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 GT3 continues to build its lead. At 600 metres, it runs at 225 km/h versus 203 km/h. At 1,000 metres, the 911 GT3 finishes in 21.23 s versus 23.11 s, with a 1.88 s lead.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Bmw M340i xDrive Touring never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.16 kg/hp vs 4.73 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.92 seconds. The 0.50 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 GT3 is slightly faster than the Bmw M340i xDrive Touring to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
