Cayenne (Manual) vs IS 300 RWD: chronicle of a drag race at 225 km/h
The launch: 0 to 100 km/h
Off the line, the IS 300 RWD hits 100 km/h in 7.40 s versus 7.70 s for the Cayenne (Manual). Despite the faster sprint time, the Cayenne (Manual) is 10 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 Cayenne (Manual) is doing 119 km/h against 124 km/h for the IS 300 RWD. The gap is 0.22 s. The gap remains stable from the start.
At 400 metres standing start, the IS 300 RWD crosses the line in 15.44 s versus 15.52 s. The 0.08 s gap represents roughly 3 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the IS 300 RWD continues to build its lead. At 600 metres, it runs at 173 km/h versus 165 km/h. At 1,000 metres, the IS 300 RWD finishes in 27.59 s versus 28.28 s, with a 0.69 s lead. Both vehicles have similar top speeds (225 vs 225 km/h), preventing any comeback.
What the numbers don’t tell you
The Cayenne (Manual) features all-wheel drive (AWD) against the IS 300 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.
Both rivals share the same electronic speed cap: the Cayenne (Manual) and the IS 300 RWD are governed to 227 km/h. At that speed, standard-fit tyres approach their safety threshold — an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
With two combustion powertrains, the difference comes down to power-to-weight ratio (7.35 kg/hp vs 6.92 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.24 seconds. The 0.30 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Lexus IS 300 RWD is slightly faster than the Porsche Cayenne (Manual) to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
