Since manuals are more fuel efficient you would think there would be more.
On many new cars, even the smaller 4-bangers, this is no longer the case. Review the mileage estimates, often the automatics get better mileage. The current Ford Fiesta shows the automatic and manual to be identical in the city (29 MPG), but the automatic gets 1 or 2 MPG better on the highway 39 (or 40 for the SFE package) for the automatic vs 38 for the manual.
“Since manuals are more fuel efficient you would think there would be more.”
Exactly, my C5 Corvette with a 6 speed manual transmission routinely gets 32 to 34 MPG at 70 mph on my “commute’” from the SF Bay Area down to Monterey. FYI most, if not all of the new Corvettes do not have a gas guzzler tax, and several models have between 500 and 640 Hp.
