You did a great job in turning the '88 Copy Cat into a Le Mans prototype from the Group C Era - its rounded, futuristic look would’ve set it apart from anything on the real-life grid back then.

1985 Testar Scuderia SC002
When rally car hit the tarmac.

SC002 was the debut of Testar Scuderia in rally world, it was designed for the Group S specification. They need a new shell for their new endurance race, the SC002 switched out the 2.0L Twincharged I4 with the SP010 (Their 1984 group C entry)'s engine. Its engine was a success in the previous season although the fuel economy is questioned because the SC002 have an AWD chassis which increase the drivetrain loss.

specs
Chassis: Carbon monocoque frame with coachbuilt aluminium panels.
Engine: 2.3L Odd-firing 60-Degree V6, single turbocharged.
~ 654hp
Drivetrain: AWD with 3 Helical LSD (mid, rear and front)

I am loving to already see all of these beautiful entries

All new for 1985 the Nexxon GTC Lynx

We started from the ground up to make our entry as powerful and positive as possible.

Then we took the to the wind tunnel to maximize the cars flow and stability.

From the turbofan rims, the exhaust and heat drafts under the rear spoiler to increase both cooling and downforce, and then we put the lights and every vent off the front (except the front brake ducts)

We are taking driver safety and injury prevention to a new level with a roll cage designed to break the spine of the car to separate the cabin from both fuel cell and powertrain in case of catastrophic crashes.

Nexxon takes performance serious but safety is our number 1 goal.

If one would use multiple technologies in the same individual tech pool, so for example one in Steering and one in Traction Aids as they share one slider. Would the penalty be applied once per slider or once per selected technology? Not sure if I should read “individual tech pool item” as the section per tech pool slider or as actual individual bits. Hope my question is clear enough

I will say once, otherwise it would be pretty hard for me to check everything

My PC offed himself (GPU broken). Therefore this challenge will be open until it is fixed. Resubmissions are allowed so everyone can enjoy the longer design time

Since im probably retuning mine, ill disclose my current trims fastest lap is 1:54.xxx

That being said im guessing mid 1:40s will be the goal?

Vorstentelg MPB-051f

Meet the Vorstentelg MPB-051f!

Vorstentelg is a Dutch passenger car brand. The name means “monarch’s scion/descendant” in Dutch. As it’s founder claims to be a descendant of Karel van Gelre, the Duke of Guelders. MPB stands for Middenmotor Prototype voor Betrouwbaarheidsraces, which translates to: mid engined prototype for endurance racing.

Vorstentelg has a long history of racing in different classes. From the 1967 MPB-034b to the Erasmus 2000 Injectie that raced in the 1972 Orisian Touring Car Championship.

The MPB-051 is another purebred racecar that is designed to participate in the most competitive endurance races held around the globe. Powered by a 2.3L Twin-Turbo V8 with 516.7 kW (692.9 HP) this Vorstentelg accelerates from standstill to 100km/h in 3.5s. Due to a lot of aerodynamic optimization the MPB-051f can reach a top speed in excess of 355km/h. However due to specific tuning for race tracks it’s limited to 340km/h.

Another example of a Group C-esque build based on road-going supercar body set (in this case, the '85 Caspita mod body) - and this one leaves my mind blown. I could see it remaining in service even into the early '90s, during the twilight of Group C.

-OOC, god I really hope I didn’t bungle my projections on reliability… Also more photos later spent too much time tweakin’ just before work >_<

Anachronisms: Pushrod suspension, Twin Charge, Sequential gearbox. Cost was 99,200 after penalties

The Seaforth Endurance 700. sponsored by Bob Player Special tapioca sticks, now with reduced asbestos.

High revving and powerful, the Seaforth car sounds the beast it is on track, it can do the automation test track in: Lap 1: 1.49.40 and Lap 2: 1.47.23. Seaforth hopes this to be another illustrious step in their long history in motorsport.

Uses 6.5k of anachronisms, all in aero (Active wing and sport undertray) and costing 93.5k it uses the full budget.

oh man why didn’t I think of better aero >_<

It was also one of the anachronism penalties I was willing to take, although I’ve been less clear about it in my post. That was the multiple technologies in the same individual tech pool I was asking about earlier. Mine has both an active wing and a sport undertray as well. And I might have gone for cooling flaps as well if my car wasn’t already quite overweight.
