Mustang V6  (Source: allfordmustangs.com)
Ford's Mustang V6 finally gets some balls

When it comes to increasing the fuel economy of vehicles to meet more strict CAFE regulations, automakers are looking at a variety of possible scenarios. Many like Toyota and Honda are pushing hybrid powertrains with vehicles like the Prius and Insight. Others, like VW and Audi, are heavily invested in diesel technology.

Ford is no stranger to relatively expensive hybrid powertrains or turbocharging, but it is using an off-the-shelf, normally aspirated V6 to boost fuel economy in its 2011 Mustang. Base Mustangs have long been the laughing stock of the sporty coupe market with drivers limping along with a "whopping" 210 hp (240 lb-ft of torque) from a 4.0-liter V6 engine. That engine is rated at 18 mpg in the city and 26 mpg on the highway with a 5-speed manual transmission (16 mpg/24 mpg with a 5-speed automatic transmission).

Ford's base 2011 Mustang, however, should be able to give a little more dignity to those who choose not to go the GT route. The 2011 Mustang is now powered by a smaller, all-aluminum 3.7-liter V6 which pumps out an impressive 305 hp and 280 lb-ft of torque (at 6500 rpm and 4250 rpm respectively). The new engine is also 40 pounds lighter than the outgoing unit.

For the eco-conscious folks out there, fuel economy is up as well despite the 31 percent improvement in power. This time around, it's the automatic transmission (6-speed) that gets the best fuel economy at 19 mpg city/30 mpg highway. The 6-speed manual transmission is not far behind at 18 mpg city/29 mpg highway.

With the V6 Mustang now within 10 hp of its more expensive GT brother, Ford is expected to announce a new V8 engine for the vehicle that will be rated at around 400/400 (hp/lb-ft).

For comparison, the Mustang V6's arch enemy -- the Camaro V6 -- is rated at 17 mpg city/29 mpg highway. Considering that the new Mustang V6 now offers relatively the same punch as the Camaro V6 while weighing around 400 pounds less means that a whole new round of pony car wars is likely to begin.

Probably has to do with it being a high compression engine. Leaded fuel was high octane so you could run higher compression without the dreaded pre-detination. If they start putting more ethenal in our fuel we might be able to go back to higher compressions as ethenol is higher octane that gasoline.

according to GM documents, it is a 9.5:1 motor, which wasn't anything special back then considering what the BBCs were running, but it is respectable considering the ancient iron heads. he runs premium with some occasional lead substitute due to it having the original valve seats.

as a comparison: 95 Monte Carlo with the 3100 engine is also running 9.5:1 compression, but with aluminum heads. mileage is about 20 in the city, around 31-35 on the highway. but with about 1/2 of the torque and horsepower of the 350, it's a fair trade in my world.
