LEARNER drivers will have to fork out less for their theory tests - saving would-be motorists around £100 million over the next decade. The cost of a theory test is being slashed by 25% in October, taking the cost down from £31 to £25, and with a further drop of £2 lined up for October next year. Theory test fees for motorbikes and other vehicles are also set to be cut, a spokesman said.

McLaren P1′s Pirelli P Zero Corsas key to performance +video

The new McLaren P1 is shod with custom-made Pirelli P Zero Corsa Tyres specially developed to meet the challenges of a 903bhp supercar. Ron Dennis has already told us that he has driven the P1 round the Top Gear test track at Dunsfold a full 10 seconds quicker than the Pagani Huayra went round, so we know the P1 has huge abilities on tap. But what’s also interesting is that Ron did his Top Gear lap on the P1′s road tyres, specially developed for McLaren by Pirelli, and not on hand-cut slicks like the Pagani Huayra.
