A Scottish driver has converted his hybrid Prius to LPG to boost its green credentials.
Freelance IT consultant Mick Gilluley from Scotland's central belt has converted it to also run on autogas LPG, which has better environmental credentials than either petrol or diesel.
Converted by UKLPG approved installer Martin Motors in Muirhead, his Prius returns on average 60 mpg.
Because the car actually runs on electric at low speed and on autogas LPG at all other times, its green credentials are what really catches the eye.
While, the environmental benefits of hybrid electric cars are well-documented, not so many people know how autogas LPG is helping improve local air quality, amongst other things.
According to the firm, cars running on autogas LPG emit less carbon dioxide and oxides of nitrogen than petrol or diesel, and 120 times less small particle emissions than diesel vehicles.
However, Mick has been a fan of autogas LPG for over 10 years and with his list of converted cars including BMW, Mercedes, Porsche, Smart and Vauxhall.
He said: "I've had the LPG bug for a long time and realised way back that it is an absolute no brainer; in that instantly upon converting the vehicle your fuel costs are all but halved.
"There's something nice about pulling up at the pump and seeing the cost of autogas LPG versus petrol and diesel.
"Of course, the environmental angle is also incredibly important and one of the reasons I drive autogas LPG powered cars."
Paul Oxford, business development manager at Autogas said: "Mick's a great example of how passionate autogas LPG vehicle owners get thanks to the fuels low price at the pump and its better environmental credentials than petrol or diesel.
"We've always long suspected that autogas LPG users are extremely loyal and Mick is proof of this. However, the benefits of driving on the cheaper fuel is also enjoyed by 170,000 other car owners in the UK, so he's definitely not alone."
