Johnson Bros of Workshop has taken two Irizars this year, as part of its fleet upgrade programme.
The first, a 57-seater, has a DAF MX11-271 engine and ZF EcoLife gearbox combination, and is liveried for the operator's Redfern Travel brand.
Director Lee Johnson says the vehicle has "instant passenger appeal" and adds: "It's a futuristic design on the i6 – very eye catching."
Its second delivery (pictured) is one of the first 13.2m, tri-axle super-high i6 Integrals in the UK. The 53-seater is powered by a DAF MX11 340 engine and has a ZF AS-Tronic gearbox.
The vehicle has been specified to a high standard, with a floor-mounted toilet, deeply padded PB seats, a Frenzel kitchen unit, and power sockets and wifi.
Gee Vee Travel of Barnsley, meanwhile, has broken its 23-year policy of buying another marque and taken its first Irizar i6 Integral.
The i6's Euro 6 DAF Paccar MX11 320 engine was part of the appeal, according to the operator.
The 12.9m, two-axle, 53-seater also has a centre toilet, twin-screen DVD system, dash-mounted fridge, reversing camera, air horns and is fully carpeted.
Owner Gordon Clarke describes the vehicle as "an eye-catcher and the customers love it".
