quote: HP/l is just another metric to help define engine performance, technology, efficiency, etc...
quote: Torque is meaningful but how the torque "feels" to the driver is different when it comes from turbocharging, supercharging, or displacement. And the implimentation of each always has different results.
quote: In addition a smaller, lighter engine will generally provide better handling dynamics than a large "V10" as you described in your fictional example.
quote: If you were an engineer you might want ALL of the information about an engine.
quote: If you need to simplify your world of performance metrics so as not to confuse yourself that's fine. But as a Mechanical Engineer who has studied engines and vehicles for many years please don't try to limit me on having ALL of the information.
quote: I wasn't aware that engines could actually do any handling by themselves. Please enlighten me.

quote: Back on topic, I believe the Mustang and Camaro's V6 are both very comparable. It's the Camaro's 400lb weight dis-advantage that is the cause of the differing EPA numbers. Also, I believe the base Camaro may have a little more agressive gearing than the base Mustang.
quote: Seriously, what good is horsepower per liter? This is about the most pointless and idiotic measurement ever used as a comparison. I still have no idea why people try to claim this as some metric. Absolutely pointless in any reguard.
quote: Your Mitsubishi probably has only about 2 liter displacement, so it has better power per liter than the Mustang.
quote: Not that I'm planning to buy one, but other than the audio tones coming out of the car, this thing should press you back into your seat just as well as older V8s.
quote: The Mustang is not about fast driving, extreme performance, back-breaking acceleration, neck-twisting handling or whatever else you might think. The Mustang is about looks, sounds, and a general impression of "powerful".
quote: If you're car is twice the weight and at higher speeds, it has to use up more energy.
quote: If you really want to save the environment, drive slow and get a electric car.
quote: For highway driving at constant speed, mass is rather irrelevant (in it's most simplistic form). The only energy it takes to continue motion of a body (reguardless of mass) is to compensate for the effects of drag and friction.
quote: So a car with less rolling friction and better overall drag (all else equal) will always have better highway mileage.
quote: You can assume "less rolling friction" implies lower weight.
quote: you seem like a highly educated person. Your posts have been informative, so thanks.
quote: However, please use "regardless" [without the "u"]. Just saying.
quote: Anyway I've watched movies and know that American motorways (interstates?) are generally dead straight
quote: And the Corvette still has leaf springs.
quote: I don't need to watch "Top Gear" (though it's a great show) to know that solid rear axles are junk.
quote: Nope, it still has the stagecoach-era solid rear axle.
quote: But which type suspension will survive longer on those rough bumpy roads? An IRS will be worn out before 100k miles on the roads I drive on while the solid axle will be going strong after 200K miles most likely.
quote: In fact that 31 mpg highway rating is a record for a car with 300+ hp -- no car with 300+ hp has previously broken 30 mpg highway fuel economy
quote: Everyone and their mother knows Mustangs are ugly,
quote: overweight hogs...
quote: Now, put $5,000 into an STi (or even a WRX for the sake of this argument),
quote: I dare you to find a car that will put down that much power that efficiently
quote: and still be drivable during a Minnesota winter
quote: we'll pull quarter miles that'll soak your mama's panties.
