Geely unveils new Guinness-certified i-HEV hybrid system with incredible efficiency
Geely has unveiled its new i-HEV hybrid system, which the company claims has a 48.41% maximum thermal efficiency on its engine. This, according to Geely, is one of the highest such numbers in mass production today.
The new i-HEV system improves overall energy efficiency by more than 10% with AI-based energy management and a dedicated hybrid powertrain which comes in multiple options including 1.5l petrol, 1.5l turbodiesel, and 2.0l turbodiesel.
The new i-HEV system achieved a Guinness-certified fuel consumption figure of just 2.22l/100km under combined conditions. The electric drive provides 230kW, which enables acceleration from 0 to 19 mph in 1.84 seconds, which is, of course, a useless number since no one counts acceleration like that.
However, Geely says the new system is optimized for low-speed urban driving and energy recovery efficiency, which is probably why it shared an acceleration number only to that speed.
The new i-HEV system will be used by Geely in China across its entire range of vehicles.

Didn't expect that one of the chinese legacy automakers still comes out with a new IC engine. We should suspect that also in this i-HEV system the IC engine is unfortunately still able to drive the wheels directly.
