The start: 0 to 100 km/h

Off the line, the X4 M40d hits 100 km/h in 4.81 s versus 6.71 s for the Explorer EcoBoost 300. At this point, the X4 M40d leads by 1.90 s and sits roughly 22 m ahead.

From 100 km/h to 400 metres

At 200 metres, the X4 M40d is doing 139 km/h against 127 km/h for the Explorer EcoBoost 300. The gap is 1.34 s. The challenger starts to claw back ground.

At 400 metres standing start, the X4 M40d crosses the line in 13.13 s versus 14.92 s. The 1.79 s gap represents roughly 75 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the X4 M40d continues to build its lead. At 600 metres, it runs at 193 km/h versus 173 km/h. At 1,000 metres, the X4 M40d finishes in 24.04 s versus 27.09 s, with a 3.06 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the X4 M40d is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Explorer EcoBoost 300 at 220 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 (5.94 kg/hp vs 6.70 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.35 seconds. The 1.90 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
