Much of the technology enableing low priced, mass produced, efficient day to day transportation econoboxes were first developed on high performance, limited production performance cars.
Fuel injection, turbos, twin turbos, superchargers, combination supercharger/turbo rigs. Radial ply tires, variable cam shaft timing, direct fuel injection, automatic air conditioning, alternators instead of generators, disk brakes, hydraulic brakes, aerodynamic design, automatic transmissions, cruise control, air bags, back up cameras, automatic door locks, ABS brakes, hydraulic brakes, and many other items were mostly first developed for high end and more expensive cars, and then trickled down to the less expensive, and higher production vehicles.
Econoboxes need super efficient motors and drivelines, light weight body construction, efficient and safe functioning suspensions, crumple zones, quiet interiors, thinner and stronger glass, lighter body panels, unibody construction, and tons of other design advances that can only be developed by their first production in more expensive vehicles.
High end, limited production car owners are the ones that spend the high dollar amounts necessary to prove out and develop many of the newest technology, that will later be refined and cost effective enought to show up on vehicles for the masses.
Some day the full aerodynamic belly pan with straked air extractors from your ACR will show up on econoboxes. Ideas developed by highly paid, leading edge engineers, will be picked up by less well paid econobox designers.
Consider our exotic car excercises to be just the developing ground for successful vehicle designs well into the future.
