Good night fella.
I loved the Vauxhall Calibra.
The Bertone designed 2000-2005 Vauxhall Astra coupe had a similar silhouette.
Sadly Vauxhall, etc... stopped doing coupes but they did make a really good looking three door hatchback that continued production years after the model year it's based on was replaced.
Even the base model Astra 3 door, the 1.4turbo looked great.
But the best of them is the VXR with a 276bhp 2.0T 16v.
The 4L60 is fine for regular use if the guts are upgraded. No sense in a stock rebuild ever on those though. Interesting on the custom 6L trans upgrade. Mostly the 6L swaps are pretty easy as the TCM is in the box and there are a few TCM conversion modules for the GEN III motors. Also, since the TCM is in the box they're not hard to adapt to any engine, which is pretty cool. 6L all the things!...?
@pip-bip Or chevy sprint, or Suzuki sprint, or Pontiac firefly, or Daewoo Lanos. A laughable excuse of a car, till you drive one with the turbo. Still slow as balls, but I defy you to find a more fun car to beat on.
@facw The current designs aren't necessarily based only on the test specification. Many manufacturers want to have their cars far exceed the limits.
The forces in a roll-over accident can be fairly significant. The force will occur in multiple directions and there could be other impacts to the pillars before the roll-over. The A and B pillars often have airbags in them making them larger.
That doesn't explain the huge C-pillars on some cars. The new Mazda 3 hatchback is good example of an oversized blind spot in the back. I can't explain that other than "esthetics".
