Triple Eight Racing MG's Josh Cook has set the pace during a truncated opening British Touring Car Championship practice session of the weekend at a greasy Donington Park.
Thanks to the tricky track conditions, the session was hit by a number of red flag incidents, which ultimately shortened the 40 minute running.
MG's Cook had held the top spot as the session headed into the business end of the running. But once the penultimate red flag was lifted, Honda's Gordon Shedden shot to the top of the order.
Cook immediately responded and became the first driver to dip under the 1 minute 11 barrier, defeating the reigning champion by little over a tenth.
Mat Jackson was third for Motorbase Performance while BKR's Aron Smith continues his fine start to the year in fourth.
Colin Turkington continues to display the raw potential of the brand new Subaru Levorg after setting the fifth quickest time ahead of Andrew Jordan and Matt Neal.
Incidentally, Turkington's effort was over one second clear of the next best Team BMR Subaru of Jason Plato, who was 17th.
Team Hard's Jake Hill was another to post an impressive performance amidst the changeable conditions after placing his Toyota Avensis in eighth ahead MG's Ashley Sutton and West Surrey Racing's Rob Collard.
