Alltid like morsomt når noen sammenligner hifi og biler; og da særlig sportsbiler.
Bare motorstyringen alene i en moderne Ferrari, Porsche, Zonda etc er langt mere komplisert enn elektronikken i et hvilket som helst lydprodukt.
Noen som vil prøve å gjette hva som er enklest/billigest å utvikle av et sportsbilschassi og ei høyttalerkasse? K-T?

The avionics system in the F-22 Raptor, the current U.S. Air Force frontline jet fighter, consists of about 1.7 million lines of software code. The F-35 Joint Strike Fighter, scheduled to become operational in 2010, will require about 5.7 million lines of code to operate its onboard systems. And Boeing’s new 787 Dreamliner, scheduled to be delivered to customers in 2010, requires about 6.5 million lines of software code to operate its avionics and onboard support systems.
These are impressive amounts of software, yet if you bought a premium-class automobile recently, ”it probably contains close to 100 million lines of software code,” says Manfred Broy, a professor of informatics at Technical University, Munich, and a leading expert on software in cars. All that software executes on 70 to 100 microprocessor-based electronic control units (ECUs) networked throughout the body of your car.

For today’s premium cars, ”the cost of software and electronics can reach 35 to 40 percent of the cost of a car,” states Broy, with software development contributing about 13 to 15 percent of that cost. He says that if it costs US $10 a line for developed software—a cost he says is low—for a premium car, its software alone represents about a billion dollars’ worth of investment.
