Mustang V6  (Source:
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.

Fail. Ever car you listed costs much more ...

Mustang (3.7l) = 305hp / 280lb.ft. - $21,000
G37 (3.7l) = 330hp / 270lb.ft. - $36,000
S2000 (2.2l) = 237hp / 162lb.ft. - $36,000
RX8 (1.3l) = 232hp / 159lb.ft. - $27,000

And none of them other then the RX8 and s2000 have 100/l.

I love that ricer argument though.

Did You know that the RX8 sucks gas down like crazy too?

And you'll notice they give up ALL of their torque in favor of horsepower too.

Short stroke + Big bore = High HP, Low Torque (and vise versa)

Also, the RX8 uses a rotary engine that while a rev-monster, has a notoriously BAD track record of reliability-- and oil consumption. They were recalling them as recently as 3 years ago and replacing the ENTIRE engine due to oil leaks as well.

I know, but I didn't want to mention it.

Almost all very high HP engines to displacement have a very short stroke and very high revlimiter.

The guy also mentioned the VQ35DE and VQ37HR in the Infiniti G35 (and g37) which neither are 100hp/l either, but are pretty good.

The penalty for getting engines like that, is you can't add a whole lot of power with boltons, whereas the v8 mustangs respond very well.
