... not entirely sure if that has been dealt with or not. I can offer some values for fuel consumption of a Spyker C8 Spyder (open):
Saarbrucken - Oxshott: driving mostly empty motorway, 140-170km/h, 3 stops
650km, 80.0L --> 12.3L/100km (19.2 miles/gallon)
Dortmund - Frankfurt - Bad Homburg: driving 140-250km/h, accelerating, slowing down, 1 stop, busy motorway
287km, 36.8L --> 12.8L/100km (18.4 miles/gallon)
(did I calculate correctly?)
