Re: Gas Mileage
When I fill the tank I divide the miles driven by gallons to get an accurate mpg. On the Roadster over three summers and 26k of mostly highway driving, I have reached 31mpg driving at 55-60 but typically drive at 70-80 (with periodic bursts to 90-100) and see 26-28 mpg. One afternoon I followed some bear-bait for 100 miles (for an hour) and still got 26 mpg.
I'm very interested to see what the SRT6 returns for mileage. While I drive fast, I'm not really a leadfoot off the line.
