Last night I travelled to Salisbury to interview the wonderfully charismatic scientist, Dame Wendy Hall.  Her team invented an internet system that pre-dated the web and we sat in her garden chatting until dusk. Waving goodbye, I squeezed past her Jaguar XF and started up the 2008.

As I looked back over my shoulder, I was startled to discover the roof ‘wave’ decoration cut into the headlining was illuminated brightly by LEDs in the dark! It’s quite the most bizarre design feature I’ve encountered in any car for years. Peugeot would call it a unique selling point but I would have preferred that part of my £17,245 to have been spent on a sat nav system instead.

Equally as startling but in a rather more appealing way was the fuel economy I achieved driving back from Salisbury. Car manufacturers make claims about fuel consumption that are impossible to match but without even trying I managed a quite incredible 68.8mpg!

This figure, of course, has now given me the incentive to go for my highest mpg ever – the magic 70mpg! I have driven on several fuel economy events in the past and been pleased with 50mpg but the 2008’s consumption was in normal conditions.

Which means I didn’t have to push the door mirrors in and take off the windscreen wipers to improve aerodynamics – or remove the seats to reduce weight!
