Zenos’ most potent model ever goes against some of the finest track weapons out there in a bid to prove its speed on the track.

The British sure know how to build a stripped, track-focused car, with the latest crop to include not only the familiar Caterham 620R and Ariel Atom in the latest 3.5R form, but also the new Zenos E10R which comes with a Focus RS engine mounted behind the seats.

With power outputs ranging from 311hp for the 620R, 345hp for the E10R and 350hp for the Atom 3.5R, the three lightweights offer immense, almost racecar-like performance on track while still retaining their road-legal credentials.

Can the new Zenos E10R compete with the established track warriors? Auto Express pits all three on the Castle Combe race circuit to find out which out is faster against the clock.
