Last year, Lotus announced the development of its Omnivore engine, the name denoting flex-fuel capability. Today Lotus released test results for the engine, along with the kind of detail on how it operates only an engineer could love. These test results cover the first phase of testing the Omnivore engine with gasoline. Presumably, testing with fuels derived from alcohol and other sources are in the next phases.
In Lotus' lab, the Omnivore engine brought in 10 percent better fuel economy than current direct-injection engines, which are the most efficient on the market.
