The driving experience is more intense, they say, the shorter the distance you drive a brilliant car. So it proved, at least, on my quickish, wettish run up the Goodwood Festival of Speed hillclimb in the brand new McLaren 570S Spider, the first time any hack has been able to slide behind the wheel.
Excellence was expected, of course. We've spent enough time in the McLaren 570S coupé to reach a general agreement that it's one of the world's finest supercars, regardless of price. And given that this new open version is every bit as powerful and torsionally rigid, rolls on the same tyres and suspension and only weighs 46kg more, there's no way it was going to be any less superb to drive.
Neither was it going to be a lot more expensive: the first 400 Spiders - launch editions tipped to sell quickly because demand for other open-cockpit McLaren models has tended to outstrip coupes two-to-one - are priced at £164,750 and can be ordered now.
