EX40 Twin Motor AWD vs Bmw 840d xDrive Convertible: chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the EX40 Twin Motor AWD hits 100 km/h in 4.93 s versus 5.06 s for the Bmw 840d xDrive Convertible. Despite the faster sprint time, the Bmw 840d xDrive Convertible is 6 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
From 100 km/h to 400 metres
At 200 metres, the Bmw 840d xDrive Convertible is doing 137 km/h against 144 km/h for the EX40 Twin Motor AWD. The gap is 0.01 s. The challenger starts to claw back ground.
At 400 metres standing start, the EX40 Twin Motor AWD crosses the line in 13.14 s versus 13.36 s. The 0.21 s gap represents roughly 10 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The EX40 Twin Motor AWD maxes out at 180 km/h while the Bmw 840d xDrive Convertible keeps accelerating towards 250 km/h. At 600 metres, the gap has dropped to 0.18 s.
Around 712 metres, both vehicles are level. This is the inversion point: the Bmw 840d xDrive Convertible overcomes its launch deficit thanks to a 70 km/h higher top speed.
At 1,000 metres, the Bmw 840d xDrive Convertible finishes in 24.31 s versus 25.14 s. The 0.83 s delta in favour of the Bmw 840d xDrive Convertible shows that top speed makes a clear difference.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the EX40 Twin Motor AWD is capped at 180 km/h, the Bmw 840d xDrive Convertible 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.
With two combustion powertrains, the difference comes down to power-to-weight ratio (5.17 kg/hp vs 5.97 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.89 seconds. The 0.13 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Volvo EX40 Twin Motor AWD is slightly faster than the Bmw 840d xDrive Convertible to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
