Off the line, the Bmw 840d xDrive Convertible hits 100 km/h in 5.06 s versus 7.54 s for the Leon e-Hybrid. Despite lacking instant torque, 340 hp of power compensates. At this point, the Bmw 840d xDrive Convertible leads by 2.48 s and sits roughly 28 m ahead.
At 200 metres, the Bmw 840d xDrive Convertible is doing 137 km/h against 125 km/h for the Leon e-Hybrid. The gap is 1.69 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 840d xDrive Convertible crosses the line in 13.36 s versus 15.48 s. The 2.12 s gap represents roughly 88 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw 840d xDrive Convertible continues to build its lead. At 600 metres, it runs at 192 km/h versus 174 km/h. At 1,000 metres, the Bmw 840d xDrive Convertible finishes in 24.31 s versus 27.56 s, with a 3.24 s lead.
The Bmw 840d xDrive Convertible features all-wheel drive (AWD) against the Leon e-Hybrid’s FWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the Bmw 840d xDrive Convertible is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Leon e-Hybrid at 225 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 11.03 seconds. The 2.48 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 840d xDrive Convertible G15 wins (5,06 s vs 7,54 s).
