A UK petrol company has launched a new ‘biofuel’ which it claims is designed to work in classic cars – but the emissions-reducing petrol blend comes at a hefty premium compared to unleaded from the regular fuel bowser.
British start-up Coryton markets its biofuels – which contain a blend of unleaded petrol and bio-organic compounds from agricultural waste – as ‘Sustain Classic’, claiming it can reduce tailpipe emissions of classic cars by “at least 65 per cent”.
While the company’s focus is selling its fuel to classic-car owners, it does not say why its product works better in older vehicles than existing biofuels – or regular unleaded petrol – on the market.
Coryton sells three ‘levels’ of biofuels: ‘Super 33’ and ‘Super 80’ contain 98-octane unleaded petrol and 33 to 80 per cent renewable content respectively, while the company’s flagship ‘Racing 50’ is a blend of 102-octane motorsport fuel and 50 per cent renewables.
However, Coryton’s biofuels come at a substantial mark-up compared to ‘regular’ 98-octane petrol in the UK and Australia.
Super 33 starts at £3.80 ($7.25) per litre and Super 80 costs £4.65 ($8.85) per litre – with Racing 50 setting buyers back £5.24 ($10) per litre.
Despite its high price, Coryton has secured a contract to supply its biofuels to at least one high-profile client in the UK, with the British division of Japanese car-maker Mazda now using the petrol to run its fleet of heritage vehicles.
In a media statement, Mazda UK said its press vehicle fleet – which includes 15 cars, from an classic RX-3 rotary coupe to MX-5 convertibles from the 1990s and 2000s – will be filled with Super 80 “each time the cars are driven or loaned to media”.
