Mazda Motor Corp said it would become the world's first automaker to commercialize a much more efficient petrol engine using technology that deep-pocketed rivals have been trying to engineer for decades, a twist in an industry increasingly going electric.
The new compression ignition engine is 20 percent to 30 percent more fuel efficient than the Japanese automaker's current engines and uses a technology that has eluded the likes of Daimler AG and General Motors Co.
Mazda, with a research and development (R&D) budget a fraction of those of major peers, said it plans to sell cars with the new engine from 2019.
"It's a major breakthrough," said Ryoji Miyashita, chairman of automotive engineering company AEMSS Inc.
[...] A homogeneous charge compression ignition (HCCI) engine ignites petrol through compression, eliminating spark plugs. Its fuel economy potentially matches that of a diesel engine without high emissions of nitrogen oxides or sooty particulates.
[...] AEMSS' Miyashita said a key issue would be how smooth and responsive the engine is.
"Is it jerky? If so, that would pose a big question when it comes to commercializing this technology." he said. "Hopefully Mazda has an answer to that question."

i dunno. biggest waste is still the breaks (red light, slow traffic) with any pure combustion engine.
my wish would be for a 5-stack wankel and a dynamo to have a baby which one could feed with butan and propan that "talks" to a big (grid-tie ready) battery which "talks" to 4 rims mated over two generations to a generator (breaking) and then a motor (accelerator)...
