The start: 0 to 100 km/h

Off the line, the 4 Long Range RWD hits 100 km/h in 6.73 s versus 6.88 s for the Prius PHEV. Despite the faster sprint time, the Prius PHEV is 7 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.

From 100 km/h to 400 metres

At 200 metres, the Prius PHEV is doing 121 km/h against 129 km/h for the 4 Long Range RWD. The gap is 0.07 s. The gap remains stable from the start.

At 400 metres standing start, the 4 Long Range RWD crosses the line in 14.92 s versus 15.09 s. The 0.18 s gap represents roughly 8 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 4 Long Range RWD continues to build its lead. At 600 metres, it runs at 176 km/h versus 169 km/h. At 1,000 metres, the 4 Long Range RWD finishes in 27.23 s versus 27.46 s, with a 0.23 s lead. Despite a higher top speed (262 km/h), the Prius PHEV never recovers its launch deficit.

What the numbers don’t tell you

The Prius PHEV features all-wheel drive (AWD) against the 4 Long Range RWD’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.

Electronically capped at 180 km/h, the 4 Long Range RWD 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.

With two plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (7.00 kg/hp vs 6.91 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.22 seconds. The 0.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
