I don't understand these phev and hybrid systems.
Am I correct in saying
Battery works with the engine giving very good mpg.
OR
Is it the car runs on battery until it is depleted and then the engine kicks in?
I am totally lost with them.
Described as a plug in hybrid
Read about the new e-Hybrid CUPRA Terramar's performance, technology, interior and exterior car design.

So plugin means you can charge up the small battery as opposed to EV that have much bigger batteries and longer range. The battery on these will give you a 76 mile range according to the web site and you can get a Cupra charger with logo

. (Pay for that bit I guess going to be all listed.)
Phev ones don't need a charger they do regenerate off running them about on petrol whilst the e-hybrid ones are crossover type of EVs. If you are a true petrol head PHEVs are hybrids but hide it better for those that can't abide plugging in. Regenerative breaking to charge up the installed battery and alternator for that.
The 70 mile range is obviously good on school runs and local shopping trips, going to work if local whilst not giving you range anxiety that some get with EVs where the likes of the Terramar will give you about
280 miles in tests.
This is where Honest John of Daily Telegraph fame use to say don't do all your motoring on battery else you'll never be able to start the engine when you need to. They may have sorted that one out now. People wouldn't toggle the car back to running on petrol then wonder why they couldn't start it. If you plug back in after use you won't get a flat battery.
