Hot hatches thread

Couple of Hot Hatches I made in 4.1, Volkswagen Golf GTI 16v + Aether Sirius GT-Turbo


You have put in so much effort into their exterior and interior design that remaking either or both of them for 4.2 is a no-brainer.

I’ll remake the Golf if the Delta body is added to 4.2

This is my first stab at a hot hatch.
I designed the car I want, not the car I deserve or can afford. So there were some must-haves:

  • Quality sliders left at zero
  • 2+2 seating
  • Low size and weight using mass-production methods (no billet) and materials (no magnesium)
  • 1.2g skidpad
  • Full double-wishbone suspension
  • Rear longitudinal boxer engine (leaves frunk, tunnel, and upper trunk as cargo / fuel areas)
  • RWD with sequential gearbox
  • Cd < 0.3
  • Roll Angle < 3 deg

With the engine I had but a few rules:

  • Has to run 98RON, 14.7AFR, with modern cat
  • No stress flags on the dyno
  • Maximum power for the given engine bay length (width was surpringly not the issue)

Engine specs (common):

  • AlSi Block and Head, lightest crank, rods, and pistons
  • 5 valve/cylinder with VVT, DI per cylinder
  • Exhaust has hi-flow 3-way cat but no mufflers

Engine specs (4-cyl):

  • 1.74L Twin-Turbo Boxer-4
  • 10.2:1 Compression
  • 294hp at 8800rpm, 240.8lb-ft at 8500RPM

Engine specs (6-cyl):

  • 1.83L Twin-Turbo Boxer-6
  • 7.2:1 Compression
  • 455hp at 8,400, 291lb-ft at 7,900RPM

Car features (common):

  • Aluminum semi-space frame with aluminum panels
  • RWD 7-speed gearbox, geared LSD
  • Sport tires (P235/45R17 front, P275/40R17 rear)
  • Vented disk brakes (2-piston front, 1-piston rear)
  • Electric Variable Power Steering
  • Full double-wishbone suspension with active sport springs, semi active dampers, passive sway bars

Car specs (4-cyl)

  • 1409kg
  • 0-60 5.47s
  • 60-0 32.7m
  • 1/4mi 13.86s
  • Vmax 182mph
  • 9.6L/100km
  • Approximate Cost $44,600

Car specs (6-cyl)

  • 1405kg
  • 0-60 5.7s
  • 60-0 32.7m
  • 1/4mi 14.10s
  • Vmax 189mph
  • 11L/100km
  • Approximate Cost $52,600

Lets go for the Non turbo version instead :wink:

With the mechanical specs you’ve given us, I think it’s more of a track-focused coupe than a hot hatch, and it should therefore be more appropriate for this thread.

“Hottest” trim of the 1992 Salon Petit facelift. Sporting a SOHC 3V 1.2 inline-four engine that makes this tiny bean absolutely fly, which may or may not make the car somewhat dangerous with its questionable amount of safety…
