So the new Impalla that chevy has released has a option for a 330 HP V8 with 28 highway fuel consumption.
Thats amazing. Just amazing. I wonder how far fuel efficency can be pushed? |

i used to get about 25mpg average on interstate trips from denver to omaha in my 305 throttle body injected 3600lb automatic 92 camaro. On the interstate i could go 360 miles to a tank. in the city i would get something like 230 miles out of a tank. roughly 14 gallon tank.
255lb ft, 170hp 5L v8.... the 70's technology designed ecm has a "lean mode" function where if the speed and throttle position stay at certain range over 60mph for so long it leans out the fuel to safe but very lean. Most new cars have that as well and they are much more aerodynamic. I think i remember being taught while working for my families gm dealership that it only takes something like 8hp to keep the vette going at 60mph once it gets there. i might be off there though. anyway, if they could get 25mpg out of a 92 camaro, 35-40mpg would seem more than feasible out of a v8 today tuning for something more like 300lb ft and 250hp. Make it a v6 and i think 50mpg with 200hp,200lb/ft should be the standard... but instead our cars have gotten heavier and more powerful. instead of lighter and more efficient. the 914 starting to look pretty good again for a daily driver LOL |
