MG's Sam Tordoff will start from pole-position for tomorrow's first race at Knockhill despite BMW's Colin Turkington impressively topping a frenetic BTCC qualifying.
Following Turkington's clash with Honda's Matt Neal last time out at Snetterton, the championship carried forward an eight-place penalty after being adjudged to be at fault for the incident.
Despite this, the WSR BMW, in the championship leaders hands, was massively quick as he finally worked into his stride towards the end of the session with a brace of scintillating laps.
In the end the Northern Irish driver set a time almost half-a-second clear of anyone else with 51.705 second lap, sending a clear marker for the front-runners come race day tomorrow.
Before that, however, the race for pole-position was anyone's game during the opening ten-minutes as the timing screens lit up from every direction with Audi, BMW, Ford, MG and Honda all vying for the top spot.
A red-flag midway through the session, courtesy of Chris Stockton's stricken Chevrolet Cruze, neutralised the running, which set up a straight fight for virtual pole between MG and Honda.
Second position, ultimately leading to pole, changed hands a number of times before Tordoff finally snatched the initiative leaving Honda to settle for a two, three and four in the order led by Andrew Jordan joining the MG on the front row.
Row two was then occupied by the factory Honda effort of Gordon Shedden and Matt Neal while MG's Jason Plato, on a different set up to that of his team mate, could manage fifth.
Continuing his fine practice momentum in sixth position was Audi's sole top-ten representive Rob Austin. Audi had looked at one point to yield two cars within the top-ten but Hunter Abbott narrowly missed out in eleventh.
Next up was Mat Jackson in seventh place for his Motorbase Airwaves squad ahead of a strong showing from eBay's Nick Foster who will start tomorrow's opening race as the highest placed BMW in eighth.
Serving his penalty in ninth was Turkington ahead of a season high effort from United Autosports Glynn Gleddie in tenth.
