Off the line, the XC40 B4 hits 100 km/h in 8.23 s versus 8.59 s for the 318d Touring Steptronic. Despite the faster sprint time, the 318d Touring Steptronic is 8 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the 318d Touring Steptronic is doing 110 km/h against 115 km/h for the XC40 B4. The gap is 0.19 s. The challenger starts to claw back ground.
At 400 metres standing start, the XC40 B4 crosses the line in 16.10 s versus 16.17 s. The 0.06 s gap represents roughly 2 m of track - barely a car length.
Past 400 metres, the XC40 B4 continues to build its lead. At 600 metres, it runs at 158 km/h versus 152 km/h. At 1,000 metres, the XC40 B4 finishes in 29.39 s versus 29.97 s, with a 0.58 s lead. Despite a higher top speed (215 km/h), the 318d Touring Steptronic never recovers its launch deficit.
Both rivals are electronically governed, but not at the same level: the XC40 B4 is capped at 180 km/h, the 318d Touring Steptronic at 215 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 (8.17 kg/hp vs 10.87 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.62 seconds. The 0.36 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, XC40 B4 wins (8,23 s vs 8,59 s).
