There are many ecomods available in spain. Plug-in and LifePO4 conversion, LPG fuel and termodynamics engine improvements. 3.1 €/100 km running cost are possible with 6500 € modification (6.84 €/100km if standard) that i will explain more detailled later.
spanish fuel prices (Gasolina is Petrol, Gasóleo is Diesel from oil)
Ministerio de Industria, Turismo y Comercio - Precios Carburantes
The only way to know prices of GNC, GNL or GLP is going directly to one gas station (
Map of stations members of Asociación Española de Operadores de Gases Licuados de Petróleo), half price per energy unit is a good aproximation.
95 octane: 1.35 €/L, 5.11$ gal. us
98 octane: 1.48 €/L, 5.6$/g
diesel: 1.27€/L, 4.8 $/g
premium: 1.33€/L, 5.03 $/g
LPG: 0.7 €/kg
CNG/LNG: 0.49€/kg
If you think this is expensive you must to know that spain have cheap prices compared with rest of Europe where they pay +70% more (european cheapest prices excluding Andorra, Luxembourg, Livigno, Ceuta, Melilla and NO TAX or VAT exceptions) .
+8%(summer) to +16%(winter) mpg increase (spanish climate is not extreme)

But if you want more range you can add 288Wh capacity LifeYPO4 battery adding 104€, EV range extended to 250 km (155 mi) only 9000€!, you will run 1.75€/100km (or 3.82 €/100 mi) or 26 mi/$ running only electric mode will last enough to a Taxi Driver day, maybe.
In USA you will find original Engineer PHEV (spanish upgraded version seems better)

A very extensive list of Cars/Engines succesful and legally converted, since 2011 only Euro2 or above petrol engines are allowed to convert to LPG in Spain (regulated European laws on LPG). if not listed there is no problem on doing conversions if your car has an ICE burning petrol 95 or 98 if: atmospheric, turbo, supercharger/compresor, otto, atkinson, any number of cylinders... I will appreciate if anyone tries converting a Miller engine (atkinson and turbo separately already converted), a TFSI (supercharged + turbo), or any multistage, biturbo ... If you read linked pdf R115 you will find big blocks american cars (It's comomn tu convert v8 on viper sr-10, escalade, F150, hummer, corvette, etc.).

Attached you will find a table of fuel cost comparison for a combination of phev, lpg, etc. in urban use, as taxi. Bcn taxi means a real taxi driven in BCN without too much care on hypermilling. In USA you have better petrol and LPG prices, better Enginer PHEV kit prices (and also you can improve the kit), LPG conversion will be a must to thing if you owned PLug-in Prius, but it's cheaper to do yourself conversion.
In spain better combination for urban use is hypermilling driving style + lpg conversion and when you drive 500.000 km you saved enough money to buy another prius... I'm wondering how much km could be done without changing batteries or having any mechanical problem (I noticed about 250.000 milles without problems but how much could be done?).
