After work late last night around 11pm and no traffic, I did some hwy runs to ease the engine up past 3500 rpms. Slowly accelerating up then decelerating back down. By the end of an hours worth of driving, then engine finally saw 5000 rpms multiple times at briefly seen speeds of 80 mph in 4th and 90 mph in 5th.
What an amazing automobile!
Finished the hour with a couple of runs with foot conrol and cruise control on relatively flat hwy stretches at 55 mph and 60 mph. While holding pedal dead still while speed varied on small inclines and desents obtained the best results, 55 mph with CC brought a range of 49 mpg to 55.7 mpg figure depending on road grade. I can SO live with that!
Loving my Mirage.
