MG driver Jason Plato qualified on pole for Sunday's first British Touring Car race at Oulton Park after a hard-fought session.
With the track drying but rain threatening, there was a flurry of activity early on. WSR BMW drivers Tom Onslow-Cole and Rob Collard, Gordan Sheddon (Honda), Andrew Jordan (Eurotech) and Plato all held pole at one time or another in the early stages.
Plato had a big moment at Cascades and reigning champion Matt Neal seemed to have secured pole for Honda when he set a time of 1m26.949s to open up a gap of half a second over the field.
Water on the track at Cascades caught out several drivers, but with just 30 seconds to go Plato's works MG snatched pole with a 1m26.872s.
"We put ourselves under a bit of pressure - I made a mistake on my first run at Lodge, then ran out of talent on the exit of Cascades," said Plato. "We had one more run so I'm really pleased with that."
Collard and Jordan also both put in strong final laps, but a couple of minor errors limited the BMW to third, while traffic held Jordan to fourth, less than 0.2s slower than Plato.
Shedden ended up fifth, just ahead of Onslow-Cole, while Frank Wrathall's Dynojet Toyota Avensis jumped up the timesheets late on to secure seventh.
Daniel Welch recorded his best BTCC qualifying with eighth in his Proton.
Like Wrathall, Dave Newsham (ES Vauxhall) seemed to struggle for much of the session, but finally moved up to ninth in the closing moments.
Motorbase managed to fix Mat Jackson's Ford Focus after its practice crash and he was immediately a top-six contender when he came out. But an air lock in the cooling system curtailed his running and left him 10th by the end of the session.
Former single-seater racer Will Bratt qualified 18th for his BTCC debut in Rob Austin Racing's Audi A4.
