Yahoo Autos Mazda MX-5 Miata sets lap records with sustainable fuel on cross-U.K. trip
As we approach an electrified world, the question of what to do with millions of gasoline-powered cars remains. New ones being built today will remain on the road for decades to come, and even if every last commuter is phased out it would be nice if classic cars don't become paperweights once fossil fuel is no longer being brewed. Enter sustainable fuels, also called eFuels, which functions exactly the same as gasoline, but is manufactured synthetically with no oil drilling, and can be put in internal combustion engines with no modification.
As proof of concept, Mazda recently drove a bone stock MX-5 roadster 1,000 miles around the U.K., visiting famous race tracks and setting record laps for alternative fuel cars. The Miata was powered exclusively Sustain, an eFuel made by a British company named Coryton. Sustain was created entirely from agricultural waste, Mazda says, using straw and crop byproducts unfit for consumption.
The weeklong roadtrip consisted of stops at Anglesey Circuit in Wales, Oulton Park in England, Knockhill in Scotland and Kirkistown in Northern Ireland. Even including the pace-setting laps, the Miata returned 45.6 mpg. By contrast, the same 2.0-liter Miata is rated at a combined 40.9 mpg in the U.K. driving cycle, sans hot laps. In the U.S, the Miata is rated at just 29 combined mpg. Perhaps just as importantly, the Mazda was able to perform with no impact on performance or reliability.
