Under the bonnet

Manufacturer technical specifications. The power-to-weight ratio is the key physical factor in a drag race.

The start: 0 to 100 km/h

Off the line, the Panamera hits 100 km/h in 5.28 s versus 5.76 s for the IS 350 F Sport RWD. At this point, the Panamera leads by 0.48 s and sits roughly 8 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Panamera is doing 136 km/h against 137 km/h for the IS 350 F Sport RWD. The gap is 0.30 s. The challenger starts to claw back ground.

At 400 metres standing start, the Panamera crosses the line in 13.57 s versus 13.83 s. The 0.26 s gap represents roughly 12 m of track — two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows. The IS 350 F Sport RWD maxes out at 250 (i.e. 155 mph — industry threshold) km/h while the Panamera keeps accelerating towards 264 km/h. At 600 metres, the gap has dropped to 0.20 s.

At 1,000 metres, the Panamera finishes in 24.66 s versus 24.69 s, with just 0.03 s to spare. The IS 350 F Sport RWD fails to fully close the launch gap.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Panamera is capped at 264 km/h, the IS 350 F Sport RWD at 250 (i.e. 155 mph — industry threshold) 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 (5.42 kg/hp vs 5.58 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.49 seconds. The 0.48 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
