Lexus Explains Decision To Discontinue Diesel Engines


Lexus Explains Decision to Discontinue Diesel EnginesLexus IS chief engineer Junichi Furuyama on why the IS diesel was discontinued in favor of the new IS 300h hybrid:

“In the beginning of [developing] this product, especially for Europe, the CO2 regulations become severe and severe… so we carefully investigated which direction – diesel or hybrid – had potential for the future. Not so right now but in the future,” Junichi Furuyama said.

“Yes, yes [in about 10 to 20 years]. Of course we can engineer a new diesel engine. But we don’t have suitable unit so [we would] have to build new one. We investigated many cases, but conclusion was that hybrid was solution to future severe regulations.

The new Lexus IS hybrid squeezes under the magic 100g/km CO2 barrier in the UK, with its 99g/km figure helping Britons save hundreds of pounds in company car tax.
