The folks over at CarWow in the United Kingdom have gathered three roadsters in a bid to see which one is fastest in a straight line. Yes, it’s a drag race featuring the BMW Z4 M40i, Porsche Boxster GTS and Audi TTS Roadster.

On paper, the fresh-faced, M40i-badged Z4 has the clear power advantage, courtesy of the turbocharged 3,0-litre straight-six engine beating under its bonnet (for the record, the 718 Boxster employs a 2,5-litre flat-four while the TTS uses a 2,0-litre four-pot).

All three boast automatic transmissions, but the Audi also features all-wheel drive (its two rivals are rear-driven, of course).
