The start: 0 to 100 km/h

Off the line, the TT 45 TFSI hits 100 km/h in 5.81 s versus 9.57 s for the 218i Convertible. At this point, the TT 45 TFSI leads by 3.76 s and sits roughly 24 m ahead.

From 100 km/h to 400 metres

At 200 metres, the TT 45 TFSI is doing 133 km/h against 109 km/h for the 218i Convertible. The gap is 1.86 s. The challenger starts to claw back ground.

At 400 metres standing start, the TT 45 TFSI crosses the line in 14.06 s versus 17.01 s. The 2.95 s gap represents roughly 105 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the TT 45 TFSI continues to build its lead. At 600 metres, it runs at 184 km/h versus 150 km/h. At 1,000 metres, the TT 45 TFSI finishes in 25.49 s versus 30.99 s, with a 5.50 s lead.

What the numbers don’t tell you

Electronically capped at 207 km/h, the 218i Convertible never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

With two combustion powertrains, the difference comes down to power-to-weight ratio (5.43 kg/hp vs 11.47 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.88 seconds. The 3.76 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
