the opel tech 1 is perhaps also worth mentioning, same period and same Cd, as the aero 2000 and it looks like it had more than a little influence on the vectra and also calibra. unfortunately not much data on this car.
the hubcaps are actually taken from a rekord, wich gives an idea of how cars at the time looked
the vectra replaced the ascona
comparing the two side by side gives and idea how revolutionary the now almost bland aero styling must have been
perhaps also worth mention again here is the
opel flextreme gte with a 0.22
i love the design of this car as it look pretty and practical at the same time,
however with -0.015Cd almost 30 years later, i wonder where the EXTREME part is
