Powertrain types
The same labels we store on every variant—grouped so you can see how petrol, hybrid, electric, and hydrogen propulsion actually differ.
Car marketing loves overlapping terms. Coriozo keeps a single canonical list in prisma/data/catalog-lookups.ts so comparisons stay consistent. Below is that vocabulary, with short explanations of what each label means in practice.
Conventional combustion
Energy comes from liquid fuel in the tank. There is no traction battery to charge—what you pour in is what you burn.
Mild hybrids (MHEV)
A small battery and motor-generator recover energy and trim consumption, but the wheels are still primarily turned by the combustion engine. You never plug these in.
Plug-in hybrids (PHEV)
A larger traction battery you can charge from the grid unlocks useful electric-only range, while the combustion engine covers longer trips without range anxiety.
Range-extended layouts
Labels vary by OEM, but the theme is electric drive with an on-board engine or unit whose main job is to extend range—not always the same as a parallel plug-in hybrid.
Battery electric (BEV)
Traction motors draw from a high-voltage battery only. Refuelling is recharging; tailpipe emissions at the car are zero.
Hydrogen
Hydrogen can power a fuel cell that generates electricity on board, or—more rarely—feed a dedicated combustion engine.
Hybrid economy and electric range depend on how you drive, charge, and climate-control the cabin—labels describe hardware class, not a single real-world mpg figure. When you compare variants in Coriozo, always read the numeric fields (power split, WLTP range where we have it, and so on) alongside the powertrain type.
