A hybrid car is a very complicated machine - more so than an EV, a turbo petrol or a diesel.

Turbos aren't very simple. The 'toyota synergy' style hybrid transaxle is a whole lot less complicated than most transaxles too. ICE cars already had an electric starter motor, so it's just adding a second electric motor and some batteries and a charging circuit.

The benefits are clear. Immense range, lower fuel consumption, longer maintenance intervals vs an ICE only, etc.

turbos are cheap and reliable, its very rare to see blown turbos on maintained non-modified cars with the exception of BMW putting them in the valley of the V8 engine and other idiotic designs.

Most turbo failures are from not doing oil changes on time or crappy modified ECU tunes.

ICE engines are incredible feats of engineering. Meanwhile, you need 2, maybe 3 parts to make an electric motor. They are dead simple. Even the control is just an inverter drive.

A turbo has about as many parts as the entire electric drivetrain. There's just a lot less to go wrong and you don't need lubrication or maintenance for solid-state non-moving parts.

I think maybe you are understating the complexity as "just an inverter drive" - highlighted by the fact so many telsas have had drive unit replacements.

right, but so are batteries and electric motors. hybrids give you a modest engine simplification and better efficiency at the cost of a second simpler type of engine.

The Prius has been around for over 20 years. They've had PLENTY of time to figure out how to make it not suck.

It's advantage for Toyota. They really should pushed PHEVs earlier like 2015, before Tesla M3 was sold.
