RWD cars with good MPG? (Looking for a highway commuter)

Consider aero mods to a small truck with a tapered cap.

The Corvette didn't get cylinder deactivation until 2014. Still, with an original EPA rating of 19/28 (16/25 revised), you could do worse for a RWD cruiser.

My dad has an S2000, the first(best) generation with the 2.0 screamer.
Here is the link to its' fuelly. I drove it to work (7 miles) exclusively and got 27.8 MPG with regular VTECs, YO. Otherwise I was hypermiling it just like my Accord, which gets about 32 MPG doing exclusively work commutes.

The gearing is just too short for good MPG in the S2000. Also keep in mind you should be running 91+ octane in it.

S2000 (Honda S2000) | Fuelly

Our S2000 is rated for 18/24, and I can tell you that is pretty accurate.

Also something to consider if you want to go upscale would be a 2011-2012(???) Mercedes Benz C300 in the 6 speed manual. Rwd sedan with room for passengers and a 18/25 rating. I got to drive one at work and holy crap does it have a nice clutch.

Infiniti G35s/G37s are also an option

I just added up my numbers for 2016 through 2018. Total of 33,020.7 miles and 943.5 gallons equals 35.0 MPG. I poke along at 57 MPH in a 55 limit. The nearest faster speed limit is over 50 miles from here.

My truck seats five adults comfortably. The box has the scratches and dents to prove that it gets used as a truck.

I've rented V6 Camaro's multiple times and got 30-32 mpg in mixed driving. I even managed 26 with the 455 HP Camaro SS with a few full throttle launches.

BMW 435 convertible will also return 30 mpg.

Ever driven the 4-cylinder? I'm curious what that will do on a long highway drive.

When I drove the Viper from Chicago to Seattle, it averaged a surprising 21.9 mpg cruising at 80 for the trip. Sometimes I wonder what it would do with actual hypermiling.

And better. A Dodge Charger V6 as to utility. Fleet spec reliability.

National’s rental fleet is only V6 and V8. (So far)

I’m curious about the Turbo 4 as well because it is shared with the Cadillac ATS and CTS. (The Cadillacs are the Camaro platform wrapped in a more sensible sedan wrapper). I want to know if the Turbo 4 saves enough fuel to make up for requiring premium.

Doug demuro did a video on hypermiling a viper. He did very poorly considering the results.

Just an update. I just bought a 2013 Cruze Eco 6sp. Got a new job 4 months ago and have a 20 mile commute, 18 interstate. I started another thread days ago asking driving tips, turbo makes it a little harder to get up to speed without drinking gas.
