Around town the Porsche is rated higher EPA despite not forcing a 1-4 shift or having a strange shift schedule.

I want to like the Corvette but I just can't get over the pushrod V8, whose <7k rev limit is kind of lame. Now that other manufacturers are coming to their senses and offering taller gears, Corvette fuel economy is no longer best in class.
Keep in mind the C7 has much more power, and over double the torque of a Cayman. It has double the displacement, and still gets the same fuel economy. That alone is pretty impressive, IMO. How high the motor revs is simply due to the displacement. The motor doesn't have to stretch out as far to develop power because of the large displacement. The 2.7 needs aggressive tuning to reach ~300 HP, and that requires a higher rev range.

Think of all the small displacement motors that develop a lot of power per liter. The F20C out of the AP1 Honda S2000 develops 240 HP from 2 liters, but requires 9k RPM to get there, with low torque. Due to complains about unusable power they had to tone it down to 8k RPM with the same HP output, by increasing displacement to 2.2L in the AP2 S2000.

I'd still rather have the Cayman, but only because there are too many Corvettes on the road lol
