Michael, I know because I'm always curious about consumption, and I'm also a Yorkshireman with short arms and deep pockets. The price of petrol annoys me immensely even though in real terms it's cheaper now than in the seventies - hell I can remember my father getting peeved when it went up to three and sevenpence a gallon. I've never seen a reason why a quickish car should necessarily be thirsty, and I always note the consumption at each tank - mentally, not an actual note, though. I *always* brim the tank and reset the odometer, and being a child of the sixties I can do the necessary division in my head.
The car consistently returns 36-38 on the commute which is from J8 M1 to London W12 - so half the distance on the motorway and half on urban roads with all the stopping and starting that entails. On a longer journey - round the M25/M2 or up to Yorkshire or Scotland, it returns 45mpg. I rarely exceed 80mph, I rarely boot it, and I calibrate my speedo with satnav units; it's within 2mph. I assume the odometer to be correct since it indicates the same 46 miles to work as a Fiat Coupe and a Seat Cupra. I do note that the original mileage claims for the xr2 were 45mpg at 75mph... Being an official 'old fart' engineer, I consider a vehicle which will not return 30mpg in general usage broken and in need of fixing! (Or alternatively, not suitable for general use.) (For the record, the Fiat Coupe (2000cc N/A) does 31/32 on the work run and 35 on a long motorway and has never been below 27 including a top speed autobahn test and a 'how far can I legally go in an hour' test. The Cupra (1.8 turbo, 180bhp) does 34 or so on the commute and 35-39 on the cruise; it's very sensitive to the cruise control between 75 and 80. It's also sensitive to how it's driven, of course.
