The motorsports outfit has collaborated with Van Sport, another UK firm, to come up with the special edition Transit in time for the van's 50th anniversary.
The Transit M-Sport rides on lowered Eibach suspension and 18-inch OZ Racing wheels shod with 18-inch Michelin rubber. There's also a new quad-tipped exhaust system, but unfortunately there's no talk of any extra power or torque from the Custom's 2.2-litre turbo-diesel.
In Europe the most powerful production variant of the front-wheel drive Transit Custom has 113kW of power and 385Nm of torque at its disposal.
The M-Sport has been fitted with a sports body kit including wheel arch and rear bumper extensions, a rear spoiler, a unique set of side sills, and a new lower front bumper with blue-tinted LED driving lights. In order to complete the rally car look, the Transit Custom M-Sport has been kitted out with livery inspired by the Fiesta RS WRC.
On the inside, the reworked Custom has unique instrument dials, leather seats with M-Sport embossing, and plenty of blue trim and highlights.
No word yet from M-Sport or Van Sport as to how many rally-inspired vans will be built, nor how much they will cost.
