Boxster vs Bmw 223i xDrive Active Tourer: chronicle of a drag race at 252 km/h
The launch: 0 to 100 km/h
Off the line, the Boxster hits 100 km/h in 5.60 s versus 6.98 s for the Bmw 223i xDrive Active Tourer. At this point, the Boxster leads by 1.38 s and sits roughly 17 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Boxster is doing 134 km/h against 125 km/h for the Bmw 223i xDrive Active Tourer. The gap is 0.93 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster crosses the line in 13.86 s versus 15.12 s. The 1.26 s gap represents roughly 53 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Boxster continues to build its lead. At 600 metres, it runs at 185 km/h versus 174 km/h. At 1,000 metres, the Boxster finishes in 25.21 s versus 27.21 s, with a 2.00 s lead. Both vehicles have similar top speeds (252 vs 238 km/h), preventing any comeback.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Boxster is capped at 262 km/h, the Bmw 223i xDrive Active Tourer at 238 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 (5.15 kg/hp vs 7.41 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.73 seconds. The 1.38 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Boxster has a clear edge over the Bmw 223i xDrive Active Tourer to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
