The start: 0 to 100 km/h

Off the line, the M8 Competition Gran Coupe hits 100 km/h in 3.19 s versus 3.33 s for the Model S P85D. Despite lacking instant torque, 625 hp of power compensates. At this point, the M8 Competition Gran Coupe leads by 0.14 s and sits roughly 2 m ahead.

From 100 km/h to 400 metres

At 200 metres, the M8 Competition Gran Coupe is doing 166 km/h against 167 km/h for the Model S P85D. The gap is 0.11 s. The gap remains stable from the start.

At 400 metres standing start, the M8 Competition Gran Coupe crosses the line in 11.09 s versus 11.17 s. The 0.08 s gap represents roughly 5 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the situation changes. Past 400 metres, both rivals hit the same electronic ceiling at 250 (i.e. 155 mph - industry threshold) km/h. Neither can claw back ground through top speed - the outcome hinges on the acceleration curve between 100 and 250 (i.e. 155 mph - industry threshold) km/h.

At 1,000 metres, the Model S P85D finishes in 20.31 s versus 20.32 s. The 0.01 s delta shows an extremely tight race.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the Model S P85D and the M8 Competition Gran Coupe are governed to 249 (i.e. 155 mph - industry threshold) 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 4.75 seconds. The 0.14 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
