Bmw 840i vs Tonale PHEV: chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw 840i hits 100 km/h in 5.12 s versus 6.30 s for the Tonale PHEV. At this point, the Bmw 840i leads by 1.18 s and sits roughly 12 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 840i is doing 140 km/h against 129 km/h for the Tonale PHEV. The gap is 0.79 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 840i crosses the line in 13.33 s versus 14.52 s. The 1.19 s gap represents roughly 52 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw 840i continues to build its lead. At 600 metres, it runs at 196 km/h versus 179 km/h. At 1,000 metres, the Bmw 840i finishes in 24.04 s versus 26.24 s, with a 2.21 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw 840i is capped at 250 km/h, the Tonale PHEV at 200 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 (5.20 kg/hp vs 6.68 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.74 seconds. The 1.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 840i has a clear edge over the Alfa Romeo Tonale PHEV to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
