Boxster Spyder vs Bmw i5 eDrive40 Touring: chronicle of a drag race at 288 km/h
The launch: 0 to 100 km/h
Off the line, the Boxster Spyder hits 100 km/h in 4.59 s versus 6.12 s for the Bmw i5 eDrive40 Touring. Despite lacking instant torque, 375 hp of power compensates. At this point, the Boxster Spyder leads by 1.54 s and sits roughly 17 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Boxster Spyder is doing 154 km/h against 134 km/h for the Bmw i5 eDrive40 Touring. The gap is 1.23 s. The challenger starts to claw back ground.
At 400 metres standing start, the Boxster Spyder crosses the line in 12.41 s versus 14.33 s. The 1.92 s gap represents roughly 85 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Boxster Spyder continues to build its lead. At 600 metres, it runs at 216 km/h versus 184 km/h. At 1,000 metres, the Boxster Spyder finishes in 22.15 s versus 25.96 s, with a 3.81 s lead.
What the numbers don’t tell you
Electronically capped at 193 km/h, the Bmw i5 eDrive40 Touring never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
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 1.54 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Boxster Spyder 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.
