I never really understand why drag racers make cars that will be disadvantaged by aerodynamics.
Surely the whole concept is to go as quickly as you can, so build a car that optimises weight saving and drag reduction.
Overall 1/4 mile in 9.5s wasn't too bad, but 8.5s would be better. 150mph plus is where the thrill really starts.
I remember claims of technical advantages, but I agree with DM that it was purely marketing. They only ran 850 estates for the first year - saloons after that.
This. I do the odd bit of fabrication for the aircooled VW crowd and last year was asked to make a dry sump tank for a type 2 bay window . Turned out the guy kept bashing his deep sump on sarf London speed bumps. OK high 14s/low 15s doesn't sound impressive... but in a camper van with full Danbury conversion (cooker, fridge etc)
Re the Volvo touring cars... wasn't the story something like the roof line of the estate gave more downforce (or probably less lift)? If the switch to the saloon occured when wings were introduced then perhaps it could have been as much for tech reasons as marketing
