The General Motors LS-based small-block engines are a family of V8 and offshoot V6 engines designed and manufactured by American automotive company General Motors.First introduced in 1997, the family is a continuation of the earlier first- and second-generation Chevrolet small-block engine, of which over 100 million have been produced altogether, [5] and is also considered to be one of the ...
Because the H2 is built to the over-8500-lb GVW, its fuel economy is neither published by the U.S. EPA nor counted toward Corporate Average Fuel Economy. [48] For example, H2 in one engine configuration averages an estimated 14 mpg ‑US (17 L/100 km; 17 mpg ‑imp) on the highway and 10 mpg ‑US (24 L/100 km; 12 mpg ‑imp) in the city. [48]

The determination of a fuel cell's performance depends on the thermodynamic evaluation. Using hydrogen's lower heating value, the maximum fuel cell efficiency would be 94.5%. [33] The efficiency of a hydrogen combustion engine can be similar to that of a traditional combustion engine. If well optimized, slightly higher efficiencies can be achieved.
