Affordable 1970s Sports Car Challenge Part 2: U.S. Federalization Boogaloo

The example vehicles were hastily modified to meet US federalization and sacrifices had to be made, the end result being cars that cost more and underperformed compared to their predecessors. Cars that had ET to spare in their initial builds will have less difficulty in Part 2 than cars that used the full ET budget, this is by design. Lower tech, lower ET builds will have their own difficulties meeting the requirements, as an OHV engine, for example, will have more ET to play with but will have worse emissions they have to fight.

ET limits in a sandbox comp like those are sort of arbitrary, just with then end goal of preventing rocket ship tech. The primary goal of part 2 is the challenge of balancing the car and making sacrifices.

Deciding to use the twilight of a true sports car run to debut the new fuel efficient unleaded octane version of their flat six, Yinzer turned the Sport into a limited run overland rally car. It has a turbocharged engine, skid plates, flip over head lights, an automatic locking rear differential, and reworked suspension with a foot of wheel travel. This is the base trim variant with value seats and radio.

Let me clarify as well, ALL cars that entered the 1st part are eligible for part 2. Instabins and rule breakers included. Just make sure you re-tune and make corrections as necessary.

Do we need rear bumpers within the height requirements, or only fronts? I ask because my body has an unpaintable, unmorphable chrome bumper (WTF??) that’s going to be hard to cover up.

Yes, in 1973, only fronts were required, but by 1974 both front and rear were required.

Try taking a bumper fixture and using it as a 3d texture to cover it up. That way the original bumper won’t show through.

MY75 Bogliq Bodkin GS


The 1973 oil crisis and the implementation of pollution controls in 1974 changed the Bodkin from a World Rally wannabe to a blue collar personal luxury coupe.

A comfortable cruiser for the driving enthusiast who likes to tour the back country without going broke.


Bogliq USA realised the average Bodkin driver didn’t want a hard riding racer, so they re-tuned it for flowing through the country, looking stylish and saving the owner money in the process!

1.8L Liberty four, 4 spd manual, 2 seats and requires 91RON unleaded fuel.

75’ Spider 6 by Posite


Well… there is more to offer then just track performance in the new model, this one has a radio and a T-top! (It is also still certainly to expensive to place well, but this was an interesting challenge none the less.)

Are the original rules still in effect as far as tire widths go?

Yes

What does that mean?

He is saying that you have that thing really stuck out there. That is setting the standards pretty darn high for everyone else who is modifying theirs and not have submitted yet.

Yeah, that it’s big.

Which is good; It fits the challenge perfectly, and I sort of love the extreme size of those early bumpers.

Ha ha yeah, this body needed all the bumper I could get to cover up that pointed nose. Every split bumper design I tried ended up looking like a felony crime against ascetics in the first place too. (Those early bumpers were practical too, can’t exactly sit and have a chat on a modern one comfortably can we eh?)

1975 and a time for change.

With the US banning the sale of leaded fuel. Prancing Fox had to make changes to it’s line of cars. The PF Vyxen 1500 was hit the hardest. Although the company managed to claw back a lot of the power lost through the lower octane fuel the effect on the engine efficiency took a hit…a LARGE hit. 25% of the fuel economy was lost overnight and couldn’t be regained without sacrificing the power output.

Along with the new “5mph bumper” and headlights saga the Vyxen looked a shadow of it’s former self. Big ugly bumpers and the removal of the pop-up headlights also took their toll on proceedings. The manufacturer had reduced the size of the front and rear logos after comments from the motor trade press journalists but the impact of the new regulations turned a sleek sports car into…Frankencar.

Here’s some quotes from our team of skilled professionals:

“Kids really want stupid decals like this?”
“It looks like a bootleg Ferrari, but I guess that’s fine?”
“I loved that old bumper. It gave the car such a classy style.”
“Yeah it’s more powerful, but it might blow up. You sure we can sell this?”

Can’t for the love of god pull down the engine emissions on my car, might need to swap it cause I may just have a powerful enough engine, problem that the game locked me in front engine placement now and it has a really tight space to work with.

Also a question, are we allowed to build a different car for Part 2 or the people participated in Part 1 must use their Part 1 entry?
