S212 E250 Wagon (2.0 Petrol engine) Drove from Woking, Surrey to Port Gaverne, Cornwall on the August bank holiday Monday. Route was M4/M5/A30. 244 miles in 3 hrs 45mins at 35mpg. Average Speed 65 mph. The traffic leaving Cornwall, north east, up the M5 was solid for 50 miles but going into Cornwall, it was the best I have ever known I would normally expect that route to take me near on 5 hrs.
