Bmw 840i Gran Coupe 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 Gran Coupe hits 100 km/h in 5.46 s versus 6.30 s for the Tonale PHEV. At this point, the Bmw 840i Gran Coupe leads by 0.84 s and sits roughly 9 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 840i Gran Coupe is doing 137 km/h against 129 km/h for the Tonale PHEV. The gap is 0.55 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 840i Gran Coupe crosses the line in 13.69 s versus 14.52 s. The 0.83 s gap represents roughly 37 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw 840i Gran Coupe continues to build its lead. At 600 metres, it runs at 191 km/h versus 179 km/h. At 1,000 metres, the Bmw 840i Gran Coupe finishes in 24.68 s versus 26.24 s, with a 1.56 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw 840i Gran Coupe 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 (5.45 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 0.84 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 840i Gran Coupe 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.
