Bmw i5 eDrive40 Touring vs Boxster: chronicle of a drag race at 254 km/h
The launch: 0 to 100 km/h
Off the line, the Boxster hits 100 km/h in 5.65 s versus 6.12 s for the Bmw i5 eDrive40 Touring. Despite lacking instant torque, 269 hp of power compensates. At this point, the Boxster leads by 0.47 s and sits roughly 10 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Boxster is doing 136 km/h against 134 km/h for the Bmw i5 eDrive40 Touring. The gap is 0.43 s. The gap remains stable from the start.
At 400 metres standing start, the Boxster crosses the line in 13.74 s versus 14.33 s. The 0.58 s gap represents roughly 26 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Boxster continues to build its lead. At 600 metres, it runs at 191 km/h versus 184 km/h. At 1,000 metres, the Boxster finishes in 24.75 s versus 25.96 s, with a 1.21 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw i5 eDrive40 Touring is capped at 193 km/h, the Boxster at 264 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 9.07 seconds. The 0.47 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 i5 eDrive40 Touring to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
