Megane E-Tech Electric 217 vs Bmw Z4 sDrive20i: chronicle of a drag race at 238 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw Z4 sDrive20i hits 100 km/h in 6.70 s versus 7.54 s for the Megane E-Tech Electric 217. Despite lacking instant torque, 197 hp of power compensates. At this point, the Bmw Z4 sDrive20i leads by 0.84 s and sits roughly 20 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw Z4 sDrive20i is doing 123 km/h against 124 km/h for the Megane E-Tech Electric 217. The gap is 0.76 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw Z4 sDrive20i crosses the line in 14.87 s versus 15.61 s. The 0.74 s gap represents roughly 31 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw Z4 sDrive20i continues to build its lead. At 600 metres, it runs at 170 km/h versus 160 km/h. At 1,000 metres, the Bmw Z4 sDrive20i finishes in 27.21 s versus 29.16 s, with a 1.95 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Megane E-Tech Electric 217 is capped at 160 km/h, the Bmw Z4 sDrive20i at 241 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 11.36 seconds. The 0.84 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw Z4 sDrive20i has a clear edge over the Renault Megane E-Tech Electric 217 to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
