That said, a N* is a good engine, just not as good as it should be. :?

The same, 300 in the high-horsepower variant. That only equals the power that v6 puts out. My point simply isn't to bash the N*-it'* a good engine, and when it came out in the 90'*, it was cutting edge- but while Honda has gone from 2.0L SOHC 4-bangers to 3.5L 300 hp V6'*, GM , mostly, still has the same engines from the mid-late 90'* in their cars today. The N* has barely been touched in the same amount of time it took for Japan, Inc. to go from 2.5L v6s to 3.5L 300 hp giants.Fuel economy? If you've got the coin to buy either a Jag or a Bonnie, putting up $25-$30 a week for some gas hopefully isin't a problem. If it is, go buy a Sunfire.

On the other hand, when you look at a sticker that tells you the car should get on average 17mpg in the city and 24mpg on the highway and after driving it almost 20k miles never having one tank average over 17 mpg you may understand someones frustration.
I thought GM was pulling in the area of 340 HP out of the Northstar? I must have it mixed up with another engine. How many models are running the Northstar today? It seems to me it may be on it'* way out. I think the standard engine for the Cad line is a V6 isn't it. Maybe I have some homework to do. I'll get back on this later.

The EPA averages are bogus anyways.....the way they masure highway fuel economy is by "driving" the car at 55 mph, with the Air conditioing and "nonessential accesories" off. Check out this month'* Car and Driver, the Patrick Bedard colummn, and you'll see for yourself why the EPA number you see on a car'* window sticker is 1 part science and 90 parts imagination. Dare drive your car in a human , real-world manner, and you can officially kiss your 17 mpg rating goodbye. The point?Don't listen to the EPA ratings on the window, since chances are , in a 275 hp GXP on a modern highway , only the Dalai Lama could do 55 mph.

EPA ratings aren't bogus, they do all cars the same so it'* a fair test.
Milage isn't just the engine'* efficiency but it'* also the transmission effeciency, gearing, the car'* weight and distribution, tires, suspension setup.

Whoever was mentionning about the Acura V6. I believe that thing only has in the neighborhood of 230/240 lb-ft of torque. That is what they dont tell you. You can have 400HP but if you only have 230 lb/ft of torque, all that HP is useless,
