It would be cool if its 150K but I doubt it would be that low if there gunna do wider body panels and maybe a small HP increase. Correct me if I'm wrong but the Gen 4 ACR carbon fiber wing and splitter was 10K alone, so imagine what wider carbon fiber body panels would be. If people want paddle shifters, Didn't Ralph say that developing that transmission would cost as much as developing the Gen V? Then again the Gen 4 costed the same amount as the Gen 3, So who knows.
$14k got you the following in the Gen IV
-CF wing
-CF Splitter
-CF cannards
-KW Coilovers
-Sidewinder wheels
-Stoptech brakes
-Sport Cup tires
-Bigger front sway bar
Alone it all costs more, however when you are removing the cost of the stock viper suspension, wheels, brakes, tires and sway bar it makes up for some of that cost.
I do not see a Gen V ACR adding $50,000 above the $99k SRT cost if it still uses the same engine or transmission. Even if it had different hood, CF aero, different brakes/wheels, tires etc. You are adding all that sure, but you would be removing any of the stock stuff (oem CF hood, etc) from the build.
