Bmw 740e iPerformance vs 308 GTi 270: chronicle of a drag race at 270 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw 740e iPerformance hits 100 km/h in 5.49 s versus 6.06 s for the 308 GTi 270. At this point, the Bmw 740e iPerformance leads by 0.57 s and sits roughly 15 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 740e iPerformance is doing 133 km/h against 140 km/h for the 308 GTi 270. The gap is 0.48 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 740e iPerformance crosses the line in 13.68 s versus 13.98 s. The 0.30 s gap represents roughly 14 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The Bmw 740e iPerformance maxes out at 250 km/h while the 308 GTi 270 keeps accelerating towards 270 km/h. At 600 metres, the gap has dropped to 0.13 s.
Around 752 metres, both vehicles are level. This is the inversion point: the 308 GTi 270 overcomes its launch deficit thanks to a 20 km/h higher top speed.
At 1,000 metres, the 308 GTi 270 finishes in 24.71 s versus 24.90 s. The 0.18 s delta shows an extremely tight race.
What the numbers don’t tell you
Electronically capped at 250 km/h, the Bmw 740e iPerformance 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 (5.83 kg/hp vs 4.63 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.52 seconds. The 0.57 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 740e iPerformance has a clear edge over the Peugeot 308 GTi 270 to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
